I am the chief software architect of a SaaS editor in france, and this is exactly what we do since 9 years+, and works well. Build numbering and tagging is done automatically on monday morning so QA can start week sprint testing on monday. We have a 3 month release cycle (except rare hotfixes). 2 month of feature dev, 2 weeks of feature completion and polishing then 2 weeks of code freeze where we test fully and document known issues. During the last phase we document, take some break and communicate the release changes to the customers. For customer release, we do 10% first wave, then 50% a week later and 100% few days later.
@@biomorphicI have 80+ customers that pay 50K per year to use my software. The time to release of my features is not the major concern. Quality code and control are the only thing that matter. I even reserve 20% of my velocity to code refactoring, I have (almost) no technical debt. Of course when I produce prototypes I will do 1 week sprints and let QA and marketing teams trigger the releases. But that's not enterprise level software development.
And so what? Make yourself a favour, do not try to lecture me. I have been working in IT for 27 years. I have enough experience to know what works and what does not. No need for a noob to tell me what is a SaaS.@@dimitarslezenkovski2116 read and learn.
I put "gold standard" in quotes because trunk based development is just another development philosophy, often promoted by agile consultants. Everything has trade offs, so before you watch this video and think I'm saying every team should be doing this, I'm not. Use whatever approach works for your team and project needs. We use git flow at my workplace project and it works pretty well. We have shipped features to prod for years now using git flow. Research for yourself, ask chatGPT to compare git flow to trunk based development.
trunk-based is definitely for no-fainted-heart people and for mature teams or senior teams. Looking to the perspective of developers, all approaches may be fun as equal if everybody can understand their benefits. However, most of the time developers aren't there to entertain themselves but to comply expectations of people that has no clue about technology and think that the smallest issue in production is a signal of weak team. So, for those reasons, trunk-based needs a huge backup in wide understanding among stakeholders. Non-surprisingly, for companies that are natively technological, as social networks, or big tech in general, that approach or similars may come as natural as it can be. But for a Bank, or another traditional institution, or government, that will not be the best.
Thanks Cody. Your "rambling" is actually quite refreshing and thought-provoking 👏. It provides those of us who are deeply entrenched in these processes with an opportunity to step back and gain a fresh perspective. I particularly want to emphasize one point that you've brought up. The development process becomes inherently more time-consuming when an organization is risk-averse. This gets even more complicated when the product is not only deployed as SaaS but also on-premise for some customers. Project managers find themselves needing release notes and translations that developers may not be able to produce. There are also other stackholders like the security team that may slow the process down.
Yeah I don’t think many people understand that a lot of software is a people problem, and if people do not like prod to go down, often that requires moral formal processes which slow down development speed in place of more environment stability.
Another element to this process is adding monitors/alarms to each stage. You deploy to a beta or preprod and a workflow bakees for say an hour. If your monitors don’t alert, your pipeline deploys to the next stage, if it does alert you configure it to automatically rollback to the previous revision
This helps a lot! especially for new devs out there, a request, if possible, could you please develop this flow/pipeline/CI-CD process from scratch for a small demo project. Thank you, there are less videos like this out there!
Absolutely would enjoy a video like this! A structure of the “rambling about a topic” style video and then a demo of whatever that was with a small/medium scale to follow it up; man, having those two things on a RUclips video release schedule would be wicked!
Thank you so much, i have an internship coming up and my recruiter gave me a bunch of courses and he expects me to know all this stuff by tommorow, this is a good summary to what I've learned so far
I must say, it is a joy watching how you've increased in subscribers the last months, just goes to show that consistency and authenticity comes a long way. The approach you have is very refreshing, as you have been told before, it is enjoyable to witness the whole process, including errors/changing stuff mid video cause it didn't work as expected etc. So many videos are shown where everything works by defualt, which is rarely ever the case when you actually are developing something, at least to my experience.
Loving these videos man! As I'm starting to look into building my first 'enterprise' system, having these different views on CI/CD, architecture and the pitfalls and benefits of different methods definitely helps! Thanks dude!
Can you go into further detail about the GH actions part of the flow? Like go into an example of building with docker and testing, etc. Please and thanks!
yeah, would love a GH actions tutorial with Dockerfile image building, testing, & deployment together with what are the notable events to listen to in order to kick off an integration/deployment
Build a project for an NGO as a volunteer, its actually my first real world project. I recruited a couple of remote devs (volunteers) to help put too, and the project was successfully deployed.

Absolutely loved this and your other video on larger scale development. I'm starting my first SWE position working on a large enterprise product soon, and I really wish this type of information was covered more in my education. Been pretty nervous because this is a huge step forward from the smaller, hackier programming assignments and projects I worked on in school and my free time. Your videos help ease that anxiety and make me excited about figuring all of this out! Thanks man!
worked in a bank in italy, they basically had 3 separate 'dev' environments where we could tesT/deploy our features, then 1 pre-prod env where users did the UAT and then the prod env. great video. tnx
You know, you might want to make sure the stakeholders get the full context of the application, otherwise they might not sign off on stuff to go into prod, so what you can do is make a separate branch that runs parallel to main, and when it gets pushed, there's an automatic build and deployment to an exclusive environment only the devs can access. And then the devs could branch off of this dev-exclusive branch to work on their features, and make sure everything is bundled together in a single release to pre-prod. And then, you could have a temporary branch for releasing to pre-prod, so you can push any last-minute bug fixes before it gets to the stake holders, and of course that would merge into both dev and main simultaneously to keep everything up to date. But that process is getting a bit cumbersome, so to keep agility high, we can also have branches for hotfixes that branch off of main, and after we fix the bug it gets merged back into main and dev to keep everything up to date. _phew_ we did it boys, we fixed trunk-based development. Wait...
Funniest comment yet. The only solution is tell stake holders that features will get deployed to prod, but they will not be active. Then when you deploy your first couple of bugs on accident, they will say “your approach needs to change”, and now you’re back to git flow.
great video! my friend and i, both new to web dev, launched a newspaper like app to our school last year and this video would have solved much of problems lol the explanation is very straightforward, thanks for sharing your knowledge!
This video is a fucking lifesaver. Been trying to figure out all of this stuff on my own and it's reassuring to know that most of the processes I came up with myself also turned out to be popular processes currently used in the industry.
Excellent advice. Here are some things I'd be interested in hearing about, if you understand them: - Continuous delivery vs Continuous deployment(drawbacks of continuous deployment without continuous delivery) - Other version control systems, mainly SVN, from the perspective of developer experience. - Workflow comparison between CI tools(mainly gh actions, gitlab CI and jenkins)
I prefer your approach from the last vid. Great to see the different options out there that people are using though. This wouldn't work for us, because our features usually take anywhere from 3 to 10 days to build. We have a main, dev, qa and staging branch, and when a dev works on a new feature/ticket, they checkout from main (which is the most stable branch as it is what is on production). There are times when it is beneficial to checkout from staging, but it is case dependent.
As usual always on point about real life software development. The thing that is often not taken into account is that you might introduce features or not corresponding to the client expectation because of not enough details. Which are working features ( so they are not triggering any test flag) it's just that the client is unsatisfied. It happens a lot (especially in agile) which is why i prefer the graph that you detailed on your previous video. Also on some project you just cant accept to have bug in prod. It comes down to what you were saying at the beginning, Every approach have trade off.
Cody, discussing your experience and thoughts is helpful for a small scale guy like me. Plenty to have in mind as things evolve....best of all you are open minded and just discussing the topic. Appreciate it
Great video! as I said in the other one, I think ppl dont understand working on large scale enterprise cous every company does it somehow different, so its great that you explain things at large scale (like enterprise) cous nobody teaches that and when a dev its just in a small team pushing pretty much to production and finds he's way into a company, they are cluless of how things work
I think on medium to large organizations you at least need some email from the user approving the changes they saw in PrePRod and then you can migrate to prod.
Your way of explanation with the diagram makes it simple to understand concepts. Please do some videos on how deployment happens with any hosting platform.

Just recently found the channel and have been really enjoying these diagraming type videos! As a new grad software test engineer who wishes to become a dev. I would love to see some career oriented videos. Or your own career path would be great as well!
I don't know how to say thank you enough, I shared this with my team, we read a business book on blitzscaling and one quote from mark zurkerberg was move fast and break things, we're at that point now 😂, so we're using the trunk based approach right now, but I see us moving slowly moving towards more complex setups cos of the nature of our application
One thing you could cover is the structure of the projects itself. What i mean - monerepos vs multirepos. How do you split your repositories. Namespaces. What belongs to Infra, what belongs to Dev/Build/Whatever. What belongs to Application. From the perspective of Day 0 bootstrapping. New rack/AWS account. You just plugged servers in the rack/wall socket. How do you structure entire work. Where does goes seed secrets and it's IaC. Etc. One thing is that you already have Infra in place. But another thing is how to get to this point. From the realm of "How do you collaborate if there is no Git server yet? How do you provision Git server if there is no Image factory. How do you harden images if there is no secret store and PKI? How do you test images if there is no servers installed?" But specifically from the PoV of project (Git repo) structure, without going into file structure itself. And another thing is how do you align developers local environment for his own local fast iteration without going trough the whole pipeline.
The devil is in the details. LOL.. Awesome! Thank you for your videos. I like how I can see that diagram unfolding on a daily basis. It's great to have this presented in a diagrammatic perspective.
in previous gitflow we clients can do testing, but in trunkbased flow can client do testing in any way or just direct testing on prod environment only?
Yes with feature flag. Release a feature behind a flag and only turn it on for a test user. Obviously it requires more orchestration and setup which is why many avoid feature flags
Continuous delivery vs automated delivery. The goal is to have one or more deployable commit every day, not necessarily to deploy every day. This allows for manual control over things like... not deploying when you are short-staffed or deploying while key team members are not available.
*My key takeaway from this video is:* trunk based development might seem easy at the beginning of development, but as you go, the complexity increases...so better use the large scale development process with different branches and environments for testing (like shown in your last video), it will benefit in long run.
you should make a video showing how this code is/ and kept secure during these processes. that would be cool. especially for us on the cyber security side of things.
Main challenge is to know what all the hype words mean. I guess I have spent a decade naming branches feature, but doing trunk based. It seems obvious that 3 weeks work on a branch is likely to lead to merge pains. If you have long running branches it’s your job to rebase regularly
(Edit I was too quick you basically describe a similar workflow as I did here): Yeah basically you set up a CI that does integrations tests (indeed more important than unit tests) on a PR, and only when the PR succeeds a pull request goes through.
The team could be doing CI into the dev branch too, but then feature flagging needs to be set up, so as an unfinished feature doesn't cause havoc for the rest of the process.
We working like this but without release tags & feature flags. So our pipelines is semi-automatic - build after pushing changes and manual deploy to test & rc env and then similar process after merging request into main branch
If a commit into main or not introduces a bug locally the solution is super simple. You reset, it takes seconds and after notifying the author you go back to work.
I think the idea of agile is good, especially for new products. Ship features, get feedback from users, pivot, ship again. The issue is no one seems to understand the get feedback part but say they are agile.
One thing a lot of people miss is if your product has multiple live versions or not. If you’re product has multiple live versions, like 1.1, 1.2, 2.0, etc., then trunk based dev may be more challenging. You will need to be able build the product for any version at any time to fix a bug or security issue. Now, if you only have one live version, like most web apps or services, trunk based development is ideal.
Thank you. We use regular git flow at our company for building web apps. Usually FE devs build the UI using the API deployed to the dev env so they don't need to run the API locally using docker and they don't need keep the local database data up to date with the latest features. I am just wondering how this might be achieved using the trunk based development.
Well done, you basically explained my dev process. What I did though is when I tag say v1.0.0, it kicks off a build and pushes to Docker Hub. Then another action updates an ArgoCD manifest to automatically update the container in a staging Kubernetes cluster and push updates to Slack that it's done. When I'm done testing staging version, then I just tag a release so without the v and it pushes and updates to my production cluster. It's automated enough that I don't even feel like I'm managing anything, I just code.
As a QA engineer, having essentially experimental code in “main” terrifies the fuck out of me 😂 For me, “main” should be your source of truth. It should be the most complete, stable version of the codebase. There’s just too much risk with the trunk based approach and not all testing can be automated.
I agree not all testing can be automated... and if it can be, it often days of dev effort to write the test that a person can manually verify in 5 minutes.
I like to look at the Linux kernel development as a kind of development. A massive project where the price you pay for a bug is a kernel crash/reboot. This development tends to favor feature branches.
I wonder, if you have staging and production environments in this case, does that mean that the staging is updated by Github Actions, and the production is updated later manually?
I think this is great except for the environments part, which is a different methodology altogether. It might be considered a deployment strategy when rolling out services and making sure they don’t immediately catch fire but it shouldn’t be part of your release strategy here. All of that testing should be done before the PR is accepted (which also has a quality gate to make sure it’s not behind main. Great video though! (Qualification - principal engineer)
Imo for 80% of companies feature flagging or dark shipping is mostly fine. I think once you get in to SLA’s with required uptimes it becomes more prudent to have a slower time to production cycle
Sometimes QA is required by contract (i.e. government funded projects) and testing a feature might require a ton of functional steps to be performed before you can reach that feature. The setup work needed for testing might be difficult to set up on unit tests or integration tests.
Thanks a lot, Cody. I have a question, though. How would you go about a scenario where you have features being worked on but not production ready, and there is a much older feature that was completed on the main branch that needs to be deployed minus the unfinished features?

Just recently found the channel and have been really enjoying these diagraming type videos!
As a new grad software test engineer who wishes to become a dev. I would love to see some career oriented videos. Or your own career path would be great as well!
I don't know how to say thank you enough, I shared this with my team, we read a business book on blitzscaling and one quote from mark zurkerberg was move fast and break things, we're at that point now 😂, so we're using the trunk based approach right now, but I see us moving slowly moving towards more complex setups cos of the nature of our application
move fast and break things until people start getting mad you are breaking things 🤣
Well done video that goes beyond the basic principles
Fantastic work! You covered all the points well 🎉 I was wondering if you were going to mention canaries but you did at the end. Superb job
yaep, that last oen was similar to canarian deplyment, but this uses different versions by redirecting users
crazy how useful everything u say, appreciate it 🌀
Glad it helps!
Good job babe!!! You changed post time on me!
One thing you could cover is the structure of the projects itself. What i mean - monerepos vs multirepos. How do you split your repositories. Namespaces. What belongs to Infra, what belongs to Dev/Build/Whatever. What belongs to Application. From the perspective of Day 0 bootstrapping. New rack/AWS account. You just plugged servers in the rack/wall socket. How do you structure entire work. Where does goes seed secrets and it's IaC. Etc.
One thing is that you already have Infra in place. But another thing is how to get to this point. From the realm of "How do you collaborate if there is no Git server yet? How do you provision Git server if there is no Image factory. How do you harden images if there is no secret store and PKI? How do you test images if there is no servers installed?"
But specifically from the PoV of project (Git repo) structure, without going into file structure itself.
And another thing is how do you align developers local environment for his own local fast iteration without going trough the whole pipeline.
There's some great information in this video thank you very much for sharing!
The devil is in the details. LOL.. Awesome! Thank you for your videos. I like how I can see that diagram unfolding on a daily basis. It's great to have this presented in a diagrammatic perspective.
Not understanding a thing but this whole development idea looks dope
in previous gitflow we clients can do testing, but in trunkbased flow can client do testing in any way or just direct testing on prod environment only?
Yes with feature flag. Release a feature behind a flag and only turn it on for a test user. Obviously it requires more orchestration and setup which is why many avoid feature flags
This is the best channel I found in years
Continuous delivery vs automated delivery. The goal is to have one or more deployable commit every day, not necessarily to deploy every day. This allows for manual control over things like... not deploying when you are short-staffed or deploying while key team members are not available.
I love these cody please keep them up
Nice videos!! Thank you for sharing your experience!
Thanks man. Awesome video. Keep it up!
Nice work man! Respect
*My key takeaway from this video is:* trunk based development might seem easy at the beginning of development, but as you go, the complexity increases...so better use the large scale development process with different branches and environments for testing (like shown in your last video), it will benefit in long run.
you should make a video showing how this code is/ and kept secure during these processes. that would be cool. especially for us on the cyber security side of things.
Very useful video thank you so much and please keep it going ❤
Main challenge is to know what all the hype words mean. I guess I have spent a decade naming branches feature, but doing trunk based. It seems obvious that 3 weeks work on a branch is likely to lead to merge pains. If you have long running branches it’s your job to rebase regularly
Great video!!! 🔥 Quick question tho, is yt your every-day job? or all this content you do is kinda a side project u have.
I have a full time job, YT is just a side hustle / for run
Great overview. Thanks!
This is gold, thanks for the content.
(Edit I was too quick you basically describe a similar workflow as I did here):
Yeah basically you set up a CI that does integrations tests (indeed more important than unit tests) on a PR, and only when the PR succeeds a pull request goes through.
The team could be doing CI into the dev branch too, but then feature flagging needs to be set up, so as an unfinished feature doesn't cause havoc for the rest of the process.
We working like this but without release tags & feature flags. So our pipelines is semi-automatic - build after pushing changes and manual deploy to test & rc env and then similar process after merging request into main branch
If a commit into main or not introduces a bug locally the solution is super simple.
You reset, it takes seconds and after notifying the author you go back to work.
Bro we are building huge startup for influencers using AI and your videos are awesome! what is your opinion about agile development/methodology?
I think the idea of agile is good, especially for new products. Ship features, get feedback from users, pivot, ship again. The issue is no one seems to understand the get feedback part but say they are agile.
One thing a lot of people miss is if your product has multiple live versions or not. If you’re product has multiple live versions, like 1.1, 1.2, 2.0, etc., then trunk based dev may be more challenging. You will need to be able build the product for any version at any time to fix a bug or security issue.
Now, if you only have one live version, like most web apps or services, trunk based development is ideal.
Working in product I needed that!!
14:23 "every team calls it something different" 😄
Thank you. We use regular git flow at our company for building web apps. Usually FE devs build the UI using the API deployed to the dev env so they don't need to run the API locally using docker and they don't need keep the local database data up to date with the latest features. I am just wondering how this might be achieved using the trunk based development.
Huge help! Thank you so much.
Your videos are helpful, Thanks alot❤ deserved a Sub🎉🎉
very helpful for starting devs. Its not that easy to find vids on overall dev process
In a huge projects it could become a merges-hell approach. When there is always a challenge to merge your code. It can take days of developers time.
This is best ❤ Thanks Wdc
Well done, you basically explained my dev process. What I did though is when I tag say v1.0.0, it kicks off a build and pushes to Docker Hub. Then another action updates an ArgoCD manifest to automatically update the container in a staging Kubernetes cluster and push updates to Slack that it's done. When I'm done testing staging version, then I just tag a release so without the v and it pushes and updates to my production cluster. It's automated enough that I don't even feel like I'm managing anything, I just code.
That sounds nice
Brilliantly simplified
As a QA engineer, having essentially experimental code in “main” terrifies the fuck out of me 😂 For me, “main” should be your source of truth. It should be the most complete, stable version of the codebase. There’s just too much risk with the trunk based approach and not all testing can be automated.
I agree not all testing can be automated... and if it can be, it often days of dev effort to write the test that a person can manually verify in 5 minutes.
i like that you like every comment. great videos btw
Thanks!
Could you kindly please share the moment when you are building the software than using diagram? I want to see in practical
I like to look at the Linux kernel development as a kind of development. A massive project where the price you pay for a bug is a kernel crash/reboot. This development tends to favor feature branches.
I wonder, if you have staging and production environments in this case, does that mean that the staging is updated by Github Actions, and the production is updated later manually?
I think this is great except for the environments part, which is a different methodology altogether. It might be considered a deployment strategy when rolling out services and making sure they don’t immediately catch fire but it shouldn’t be part of your release strategy here. All of that testing should be done before the PR is accepted (which also has a quality gate to make sure it’s not behind main. Great video though! (Qualification - principal engineer)
Great video, well explained! The visuals also help anyone with ADHD 😊
Imo for 80% of companies feature flagging or dark shipping is mostly fine. I think once you get in to SLA’s with required uptimes it becomes more prudent to have a slower time to production cycle
Sometimes QA is required by contract (i.e. government funded projects) and testing a feature might require a ton of functional steps to be performed before you can reach that feature. The setup work needed for testing might be difficult to set up on unit tests or integration tests.
can you go into more detail about the tests, how they are made, what do the tests mostly target etc
Please make more of these types of videos
Nice. Can you share a little insight about user story and how to make it for us the junior? Really appreciated that 🙌
These videos are super useful.
Gold video, keep it up :)
Thanks a lot, Cody. I have a question, though. How would you go about a scenario where you have features being worked on but not production ready, and there is a much older feature that was completed on the main branch that needs to be deployed minus the unfinished features?
Probably feature flags, wrap the code with flags to prevent the code from running, then enable it when it’s reDy
I can say it was like this when i worked for big company
