Completed this entire series, Thanks for the explanation. 1. Terraform migration ( using import and then running terraform import command which will create a state file). - This will import the EC2 instance all details which was created manually. - Importing EC2 instance to create a state file. # 2. Terraform drift detection ( if some one manually changed any settings for any resource, then detecting that change is called drift detection). # There are 2 ways to detect it. Scenario 1: Use terraform refresh using a cron job. ( terraform refresh, refershes the recents changes which was done manually to the statefile and keeps it updated. Scenario 2: - A) Use audit/activity logs to see who made changes, if its changed by user and resources is managed by TF, then send an alert using lambda/azure functions and notify. - B) Apply strict IAM rules so that no one can login to console.
Thank you Abhishek for making this video and explaining the import scenario... because these are some of the most commonly asked scenario questions in the interview!
Amazing series!!!! This has helped me a lot in quick interview pre. I am a SRE with 6 years of exp working on terraform from close to 5 years on and off. You have amazing straight to the point teaching skills.
Thank you so much for the entire series and this surprise video! I'm so addicted to your teaching style and real-time scenarios you bring in. I really appreciate your time and efforts for all the free DevOps content. God bless you 🙏
After running >terraform plan -generate-config-out=generated_resources.tf this command I was getting an error saying >Too many command line arguments. To solve this you have to put generated_resources.tf in quotes. So the command would be: >terraform plan -generate-config-out="generated_resources.tf"
I was stuck with this too. ChatGPT was unable to solve this issue for an hour. Thought to check the comments to see anybody else got the same issue. And now its resolved. Thank you!!
Thank you, Abhishek, for this surprise video. I really appreciate it. I would like to request the next series to focus on scenario-based questions for each tool ( Jenkins ,Docker, K8S , AWS) you have covered previously. Thanks
Hi Abhishek,can you please make a video on complete monolithic/microservice project deployment from setting up the infrastructure in cloud to deploying the app to production by showing the differences among deployments in vms,containers if possible
Terraform series is super and more effective. Could you please prepare similar with Azure Cloud. For example, creation of VM, Networking, User data or provisioner, Azure Key vault, Azure blob storage for backend etc... Also some real time project examples.
Abhishek can you please explain that also how we can use resource of one resource and used in other resources and taint and untaint , for_each ,count,count.index, function..but one think i can say all of your series are wonderful..now one can provide this type of knowledge share free pf cost .. thanks alot your inspiration for many people
Thanks Abhishek for these wonderful videos. Can you please make some video on Sentinel policies in terraform, as I am facing same Question in the multiple interviews
hi abhishek, will you explain more about data resource concept. please create video where two different project connect with each other and transfer details or use details of each other or project 1 required details from project2 to run
Hi Abhishek, Scenario 1: Use terraform refresh using a cron job. ( terraform refresh, refershes the recents changes which was done manually to the statefile and keeps it updated. Where i have to mention cron job?
Hi @abhishek ,i have one questions related terraform import command , If i have import the Ec2 instance using import command and after that try to add one extra volume on particular that instance using terraform ......if i run terraform plan command so it shows first i will destroy the instance and then create and attached this extra volume ......please help to address this issue .
Very helpful series. I have faced many interview questions that you explained in this series. I am following your all the series and improving my knowledge day by day. I have one doubt in import command. By using terraform import are we able to import on one resource at a time ? and if yes then how we can import multiple resources at one time. Also how to resolve the error "resource already exists" in terraform. Suppose I have main.tf with 5 resources and I deployed that already and after that I made changes in four of them and again deploying using terraform apply then I will get error for that one unchanged resource as its already exists.
Thanks for the surprise video Abhishek, really appreciate your hard work. I have a quick question on the 1st scenario. If we want to migrate more than one resource to terraform and not only EC2 instance, how do we achieve that? The command you shared is for resource block and we create a lot of resource blocks to achieve other resources, do we run the command multiple times or do we have a method to achieve this from one command?
How to setup lambda function can you please do it practically if anyone modify the state file?also could please make a video on lamda function layer and different use cases
@abhishekveeramalla Can the Terraform lock concept be used to prevent the multiple users change the infra as in the case of scenario-2 in the video? How can this be explained?
This importing method was not working for me giving error - only managed resources can be imported. I did it another way by writing resource block in main.tf including ami and instance_type. then ->terraform init ->terraform import aws_instance.example instanceId. This generated statefile with all info of aws instance whose id i provided
Hello Abhishek...u gave an example of one resource migration ie;Ec2...and how do we migrate multiple resources like S3, vpc, etc,. under one terraform project...and how do we use terraform import command for multiple resources.
hi abhishek sir, thankq for providing this wonderful series of terraform , i hve watched all urs videos of terraform frm day1 . while solving this import senario im getting an error as Error: Too many command line arguments │ │ To specify a working directory for the plan, use the global │ -chdir flag. could u please help to how to resolve it , thnks in advance🙂
Sir One silly doubt, Is there any way to import 1000 resources at a time in terraform without mentioning each and every resource id in the terraform configuration file. For example somethimes we mention (*) for all the contents.
Hi Abhishek, you have installed a CLI and then had connected an instance. Can we use Linux AMI and can use putty to connect and then can access same instance through Linux, could you please confirm is that method is also available to connect?
Hi Abhishek, I have one doubt. sometime back I learned on youtube that to use already created VPC resource in our terraform we use data block. Is this the best way or the one which you explained about terraform import command. or is there any difference in both. Thanks
Thanks Abhishek for the amazing content , i was able to learn all the basics of terraform because of you . i just had one doubt so while importing existing resources to terraform we need to have all the id tags of every resource that is existing then ?
hi Abhishek, I want to setup Terraform from my client and we're a team of 6 people managing AWS Infrastructure. Can you let me know how should I set this environment and make it secure? For a single user, I can create an IAM User and use the security credentials, but I am sure how to do it for entire team. Should I use Git & Jenkins for automation.
Hey Abhishek Thank you so much for this course and all the courses. By learning all your series can someone show 3 years of experience? I mean this is for freshers only or for experienced people also?
Thanks Abhishek for wonderful video.. While replicating, I am getting the below error while running terraform init , please suggest which point I missed. Error : Unsupported block type Block of type "import" are not expected here.
Hi Abhishek, i have doubt that can we integrate terraform with jenkins. Can you please make a video on this. Please 🙏🙏 Many thanks for your efforts and the technics you use to make understand in easy way. By asking questions your self on behalf of viewers... Once again thank you.
Hi Abhishek. I have watched terraform till day 7 classes. Almost all the things understood but slightly there is confusion on modules and workspaces. I want to know about these deeply. Can u plz guide any resources?
Thanks for the Series...great Stuff @AV 👌👍 !!! A QQ , pardon my ignorance ,where does the cron job reside/needs to be created in scenario 2a ?Please lemme know . .
Hello Abhishek, In Your video instance is running on N Virginia region.when you are importing the instance in that you provide us-east-1 region. When we are importing configuration that time region mandatory or not? Due to some issue i am not able to do practical that why I am asking this question. Thank You
Hi Abhishek, Could you please let me know if I want to import a S3 bucket, an ec2 instance with a security group attached ( other than default one) which I might have deployed manually,in this case do I have to use three separate import blocks for each of these resources (s3,ec2 and the security group which is attached to the ec2 instance)...i.e. The id field in the import block will have the bucket id, instance id and sg ID or the whole import of three resources can be done from same import block ?
Hi abhishek, I have one more question. If terraform command is being executed from personal system of devops person and same user did the change manually. How lambda function will understand because the user is same. Either he did it from console or setup secret in local and perform terraform commands
Completed this entire series, Thanks for the explanation.
1. Terraform migration ( using import and then running terraform import command which will create a state file).
- This will import the EC2 instance all details which was created manually.
- Importing EC2 instance to create a state file.
# 2. Terraform drift detection ( if some one manually changed any settings for any resource, then detecting that change is called drift detection).
# There are 2 ways to detect it.
Scenario 1: Use terraform refresh using a cron job. ( terraform refresh, refershes the recents changes which was done manually to the statefile and keeps it updated.
Scenario 2:
- A) Use audit/activity logs to see who made changes, if its changed by user and resources is managed by TF, then send an alert using lambda/azure functions and notify.
- B) Apply strict IAM rules so that no one can login to console.

After running >terraform plan -generate-config-out=generated_resources.tf
this command I was getting an error saying >Too many command line arguments.
To solve this you have to put generated_resources.tf in quotes. So the command would be:
>terraform plan -generate-config-out="generated_resources.tf"
Thanks.. It is working !!!
I was stuck with this too. ChatGPT was unable to solve this issue for an hour. Thought to check the comments to see anybody else got the same issue. And now its resolved. Thank you!!

How to make terraform more responsive?
Someone asked this question in my interview
What does that mean ?
This is not a frontend web right to make it responsive 😢
Simlarly in case of Azure We can use Azure Activity logs who have done the changes whethter it is a service principal or an AD user . Am i Correct ?
Thank you Abhishek. I have a question If tf state file got deleted by mistake how can we get it back?
Best practice is to use backend with version control. Delete means need to play with this import
