Hi Bro. Thanks anna for the free courses , i got a good job in one of the MNC company as senior Cloud infrastructure as service role. If every person in IT dedicates some free time for others instead focusing on scraping money from others for time, no one would be jobless. Your initiative is helping others including their dependent families, no other employee would do same as you. Thanks anna.

🎯 Key Takeaways for quick navigation: 01:42 📋 *State file in Terraform is where Terraform records the information of the infrastructure it has created.* 03:29 📋 *State file is important because it helps Terraform update and manage existing infrastructure instead of creating new instances or resources.* 07:36 📋 *Advantages of using the state file include updating existing infrastructure and destroying infrastructure in a controlled manner.* 08:05 📋 *One drawback of the state file is that it records sensitive information, such as passwords, by default.* 09:17 📋 *Storing the state file on a personal laptop or any vulnerable device can compromise the security of sensitive information in the state file.* 10:23 🛡️ *Real-world scenarios involve multiple DevOps engineers collaborating on a Terraform project.* 12:12 🛡️ *Storing the entire Terraform logic, including the state file, in a Version Control System can compromise sensitive information.* 14:31 🛡️ *If the state file is not pushed to the Version Control System, Terraform may not know about updates and can delete the corresponding infrastructure.* 16:35 🛡️ *Using a remote backend solves the drawbacks of storing the state file in a Version Control System.* 19:04 🛡️ *With a remote backend, the state file is automatically updated in the external resource (e.g., S3 bucket) when applying Terraform configurations.* 20:41 🛡️ *Storing the state file in a separate remote backend, such as an S3 bucket, enhances security and prevents sensitive information from being exposed in a Version Control System.* 21:09 🛡️ *Multiple remote backends can be used, such as S3 or Azure storage, depending on the cloud provider being used.* 23:13 🛡️ *With a remote backend workflow, DevOps engineers can clone the GitHub repository, make changes locally, verify them with `terraform apply`, and raise a pull request to update the remote state file stored in the S3 bucket.* 27:30 📂 *Before running `terraform init`, there will be no state file available. After running `terraform apply`, the state file will be created and populated with resource information.* 29:03 📂 *The populated state file contains information about the created resources, such as the instance ID, public and private IP addresses.* 30:46 🛡️ *Storing the state file in a Version Control System is not recommended due to security risks and the potential for forgetting to push updates to the state file.* 31:16 🛡️ *Terraform can show the state file using the `terraform show` command.* 31:29 📂 *Deleting the state file can cause Terraform to lose track of the created resources.* 32:10 🛡️ *Using a remote backend like S3 requires creating a `backend.tf` file with the necessary backend configuration.* 33:24 🛡️ *Copying and pasting backend configuration from the HashiCorp documentation or using extensions can simplify the process.* 35:16 🛡️ *S3 bucket creation can be done manually or with Terraform, ensuring unique bucket names.* 37:02 📂 *The S3 bucket name and region are required in the backend configuration.* 38:38 🛡️ *Initializing the project with the backend configuration will create the S3 bucket.* 40:29 📂 *The state file will be created and stored in the S3 bucket instead of locally.* 41:37 📂 *The state file can be stored in an S3 bucket instead of locally.* 42:09 📂 *Using a remote backend allows storing the state file in S3 and accessing it from there.* 42:38 📏 *Modifying the code no longer requires handling the state file manually.* 44:13 🛡️ *Terraform uses locking mechanism to prevent conflicts when multiple people try to update the same project simultaneously.* 45:22 🛡️ *DynamoDB can be used as a locking mechanism for Terraform projects.* 48:15 🛡️ *Adding the DynamoDB lock details to the backend configuration enables Terraform to handle locking.* Made with HARPA AI

Hi Abhishek. Initially you have created S3 bucket and later we deleted statefile. then again we tried to create S3 bucket with same name and configuration with out state file. and we used remote backend to store state file in S3. But if we use same name and configuration which already used we'll get error right. stating Resource already exists. Can you explain on this.

Hi Abhishek, in timestamp@42:00, when you say, no one will have access to state file/backend.tf, but when devOps is creating a resource, wouldn't the state file required and visible at the root of the repository? Terraform must know the presence of the state file to avoid duplication of the resource. Correct?

As suggested by terraform, can we go with option suggested ? will solve if we miss configured ? Initializing the backend... Error: Backend configuration changed A change in the backend configuration has been detected, which may require migrating existing state. 1. If you wish to attempt automatic migration of the state, use "terraform init -migrate -state" 2. If you wish to store the current configuration with no changes to the state, use "terraform init -reconfigure".

When we moved state file to S3 and linked locked file to Dyanamo DB , my assumption was .terraform.lock.hcl shouldn't be created in local as locking is taken care by Dynamodb (Like the way i dont see state file ln local ) . However , I do see lock file in local . I created new folder and tried doing same , still lock file is getting created in local . -- Can you help understand this ?Im i missing something?

Hi Abhishek, first of all thanks for amazing series. I have few doubts in this video. 1) I don’t understand the flow how statefile is being stored in S3 bucket. You said when we run terraform apply then statefile is generated in s3 bucket. But what if I run terraform apply and then my PR got rejected? Basically I wanted to know how this remote backend mechanism will work in case of feature branches? 2) What if I just wanted to try out some things and run terraform apply several times. How statefile is stored in that particular scenario?

Hi 1. if the Pr is rejected and you make necessary changes and do terraform apply, state file will also get updated ryt. You don't need to worry what is happening in state file. It will be updated accordingly. 2. any number of times you try to apply state file will update the same. So as mentioned before updating state file is something terraform will take care. We don't need to get worried

Hi Abhishek, The lock file is pushed to remote n not on local only so it will be able to use lock mechanism if simultaneously t-apply is done? Also in our project we use terragrunt and the explanation is given by the architect on his LinkedIn post i wish you code read n explain it to me in simple words..i cant paste screenshot here but he has written about backend cant be modified without init and that terragrunt allows module level statefile

Question - How does the ".tfstate" file in the S3 bucket get updated in these cases: 1) Another developer raised and got his PR merged without doing 'terraform apply'. 2) Another developer did 'apply' the code, then ran 'terraform destroy', and then got his PR merged.

1. Another developer raised and got his PR merged without doing 'terraform apply'. As source code merged, if any another resource performs terraform apply command resources will create and update the terraform state 2. Another developer did 'apply' the code, then ran 'terraform destroy', and then got his PR merged. a. if apply terraform apply command resources will create and terrafrom state file will update b. terraform destroy command will delete the created resource and at the same time terraform state file will also update will remove all attributes c. PR got merged but terraform statefile is empty. if some one again run terraform apply it will try to create new resources.. so it is essential to make sure to run terraform plan command before apply to know exactly what going to be happen

Hi Abhishek, I have doubt at 20:54 , What if DevOps engineer pushes the Terraform code with out executing it.? He updated the infrastructure but didn't execute "Terraform apply" and pushed it to repo. what happens in that case? Does it lies in the hands of PR reviewer to check ?

Even if we store in git hub repo and forget to push statefile.. cant we always fire terraform refresh command once before starting any changes.. then there wont be any negative side of using statefile in git? Am i right?

Hi, As the state file contains sensitive data and it will be in s3. What about the file providers.tf which contains aws_secret and aws_key ? How can I secure it ? Can I create it and after the first terraform apply command, delete it ?

Hi Abhishek, Kind request. Please answer the below common question which i encountered in most of interviews. We have created the AWS resource for ex an ec2 instance through terraform, and then the state file gets deleted. If we reapply the same terraform code for recreating the ec2 instance. what will happen, will the ec2 instance will be created or not or there will be any errors.

Thanks for the reply@@AbhishekVeeramalla from the video you have explained, like if state file is not there and we create the resource again with minor change it will recreate the whole resource from scratch. But what happens when state file is not there and we re apply the same code without any change. My understanding is that it will create the resource with different ID, Is that correct? please clarify?

Hi Abhishek Anna. What happened in remote backend and Locking mechanism. If some one pull the terraform config file and made some changes. And without terraform apply he was push the updated terraform config file to Github then how tfstate file will track the changes.
