Yes, finally a clear explanation of CI and CD. Thanks.
I would like to see more videos from Eric Minick. He explains really well and I understand concept in first watch of the video as a layman.
I can't imagine how thorough one must be with these concepts, to explain them in a way that Mr. Minick does. The guy made my jaw drop with his presentation and speaking skills, like DAAMN!
Thanks for the appreciation, Syed, glad you enjoyed the video! 🙏
Thank you Syed!
This guy explanations are always very clear and concise, would love to see more of him
I loved this style on writing in front of the teacher, pretty cool. Very good content also, thank you
Thanks for watching, Vik!
Meanwhile, I'm already impressed by how well Mr. Minick can nonchalantly write backward while explaining everything so nicely!
Probably inverted, seeing that the cloth branding is on the opposite side.
Hey Hossam! You got it right. Here's a post to explain how these videos are created 👉 ibm.co/3qcuu2w
Love the simple, straight-to-the-point explanation, Eric. Hope to see more of your videos.
Another fantastic explanation. Thank you so much for making this so clear. I feel much more prepared to talk intelligently about this.
2021: Legendary explanation :D
Thanks!
Thanks for sharing. Awesome explanation of CI/CD for the beginners
I loved this video. Thank you for all your insights.
You're welcome, Marcio, glad you liked it! 👍
Excellent articulation of CD
Your explanations are easy to follow 👍
Great explanation 👍🏻
great explanation of CD for a non programmer ;)
Watch this short video now to save hours of your time scouring internet watching and reading half-baked, vague materials making you even more confused.
Thanks IBM cloud.
Great explanation. Thank you.
Fantastic explanation, thank you.
Well articulated. Got it
CI breaking of things .CD Not breaking of things
Thanks so much for this tutorial.
Thanks for watching, Roman! Glad you enjoyed it! 😃
that was helpful..Thank you
what difference might be between testing QA and Stage?
Many groups I work with have a sequence of testing environments. Generally, faster / cheaper tests are run in lower environments more often. An environment like "Stage" might be used for slow user acceptance environments. As a best practice, more automation and fewer environments is better.
So Continuous integration is one phase of CD?
CI is typically understood as "continuous build" and in that sense it's a phase/step of CD. Some look at CI as constantly integrating code into a common code line and testing it aggressively to learn if it's better or worse than what was there before. All of those downstream deployments and tests are then natural things down as part of CI and you could think of Release as "testing to see if our customers/users like it better" as well.
The lines are really blurry here in when you get into the philosophy.
But when you think of CI as "Build and build-time tests" then yeah, it's a step.
CD is not about the pipeline itself or any tooling. In fact, the idea is much deeper. Maybe listen to Dave Farley, the co-author of the Continuous Delivery book. He's much better at explaining his idea.
He says you always want the software to be in a releasible state such that it's no longer a technical decision when to deploy. The tests need to give you enough confidence to pull the trigger whenever the pipeline completes successfully. It's a definitive indicator whether the code can be shipped.
Also CD is a work philosophy. You want to make lots of small changes (experiments) and deliver them as fast as possible to gather customer feedback and adapt the product accordingly. The pipeline is just a means to this experimental style of agile software development.
And the CI part is also important. In a proper codebase you'd only have a single branch. This forces devs to work in very small steps and integrate it with all other commits at least once per day. Unfinished code is hidden behind feature flags if necessary. That way you surface other devs changes immediately and don't get crazy merge conflicts. Also there's an emphasis on the latest version because only that version is relevant.
Excellent
thank you very much!
CAB is Change Advisory Board; not Change Approval Board
Good catch. 1 take video without a firm script :)
Hi, Automatic test means , unit tests written while coding or test automation ?
"Yes". I love unit tests and they should be part of your build and monitored in that stage. The tests in QA/Stage/Perf/Whatever are runtime tests. Another video on this channel goes into Continuous Testing in more depth.
Awesome explanation .. I wonder how you shoot your videos with the glass and pens and the instructor behind it
The crew in our studio has an awesome setup. Led lights enter the side of the glass to make the markers "pop". Then in post-production they flip the X-axis. I don't wear my wedding ring on my right hand.
Took me a few seconds to realise how this video was done. Clearly it was flipped horizontally post-production.
yes, while filming he was clearly hanging upside down from the ceiling
@@mikesmith8293 nice catch
No idea why .. this guy nailed it into my head ..x..l..n..tee
What is a "Build"? is it compiling the code?
Compile and package into an installable artifact. Yes.
automatically
Can u bring in Python. Just make video . Name your price.
Is he actually writing in mirror type? Geez... Let’s think: he has a wedding ring in ”wrong” finger, right finger... so he probably wrote normally but the whole video was mirrored in post-production.
Correct. I'm dysgraphic and have bad enough hand-writing without trying to write backward. I did have to put Build on my right and Prod on my left which was unnatural.
nice skill of writing backwards...
Video editing my friend. Flip across the Y-axis, hence the wedding ring appears to be on my right hand.
Change playback speed to 1.5x , Thank me later :D
