terraform state push not working

In previous versions of Terraform, the only way to refresh your state file was Terraform has been successfully initialized! This allows you to review any updates to your state file. see any changes that are required for your infrastructure. Create an S3 bucket that will hold our state files. => nothing in local, file in s3 OK The state file format is a private API that is meant only for internal use within Terraform. Successfully configured the backend "s3"! Not the answer you're looking for? Open main.tf to review the sample configuration. There are a number of other built-in functions that you can use to manipulate strings, numbers, lists, and maps. destroyed the instance and wants to remove it from your state file. I have a team of ~40 people working across 250 AWS accounts with multiple statefile and statefile buckets, and we are all puzzled by this whole piece. Resources: 1 destroyed. The web server cluster you created in Part 2 of the series should be moved into stage/services/webserver-cluster (think of this as the testing or staging version of that web server cluster; youll add a production version in the next part of this series). All of the databases output variables are stored in the state file, and you can read them from the terraform_remote_state data source using an attribute reference of the form: For example, here is how you can update the User Data of the web server cluster Instances to pull the database address and port out of the terraform_remote_state data source and expose that information in the HTTP response: As the User Data script is growing longer, defining it inline is becoming messier and messier. Terraform Format checks whether the configuration has been properly formatted. Variables aren't allowed in a backend configuration. OK, I think I figured out how to do this (or at least, these steps seemed to work): I then used "terraform state list" and "terraform plan" in the new folder to sanity check that everything seemed to be there. If you forget, other commands will detect it and remind you to do so if necessary. removing an existing resource from state and gives you a chance to correct your the refresh subcommand, -refresh-only mode is supported in workspaces using rev2023.4.17.43393. Backup your file doesn't mean that we need to save it to our repository. Co-founder of Gruntwork, Author of Hello, Startup and Terraform: Up & Running, resource "aws_s3_bucket" "terraform_state" {, resource "aws_s3_bucket_versioning" "enabled" {, resource "aws_s3_bucket_server_side_encryption_configuration" "default" {, resource "aws_s3_bucket_public_access_block" "public_access" {, resource "aws_dynamodb_table" "terraform_locks" {. Putting the two previous items together, the result is that workspaces can be fairly error prone. I'm going to lock this issue because it has been closed for 30 days . Sign in Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to take exactly these actions if you run "terraform apply" now. Always backup your Terraform State file "terraform.tfstate". I have a few questions: The same error occurs when the state is stored locally on disk. For a remote state file stored in an Azure Storage account container, you can locate the file and use the Break lease button. How do I force "git pull" to overwrite local files? Try the features you heard about at HashiConf including CDKTF Golang support, and the Terraform Cloud private registry. For PowerShell on Windows, use Set-Content to automatically encode files in UTF-8 format. If you ever set or change modules or Terraform Settings, run "terraform init". For example: S3, Dropbox, etc.. (with versioning turned on). OSS or Terraform Cloud. @blaltarriba @tanmng: Are you certain there is only 1 terraform and backend config block in your config files? In general, embedding one programming language (Bash) inside another (Terraform) makes it more difficult to maintain each one, so lets pause here for a moment to externalize the Bash script. What is the difference between 'git pull' and 'git fetch'? This is the easiest method to link the two up, so let's do it. manage and execute your Terraform projects. You may now begin working with Terraform. However, if you use Set-Content it formats the document as UTF-8 by default. attempts to reconcile the resources tracked in your state file with your actual To retry writing this state, use the following command: terraform state push errored.tfstate Thats because the state files in each workspace are isolated from one another, and because youre now in the example1 workspace, Terraform isnt using the state file from the default workspace and therefore doesnt see the EC2 Instance was already created there. You should see something similar to this: With this backend enabled, Terraform will automatically pull the latest state from this S3 bucket before running a command and automatically push the latest state to the S3 bucket after running a command. Details of these are below. You can check this by heading over to the S3 Management Console in your browser and clicking your bucket. .github/workflows/terraform.yml again to reinitialize your working directory. If you take a look in your S3 bucket, youll find a terraform.tfstate file in the workspaces-example folder: Lets create a new workspace called example1 using the terraform workspace new command: Now, note what happens if you try to run terraform plan: Terraform wants to create a totally new EC2 Instance from scratch! Does the backend config in .terraform/terraform.tfstate look correct? The Terraform documentation states: Terraform also put some state into the terraform.tfstate file by default. Converting terraform.tfstate to Unix-style line endings fixes the problem. You're not sure what happened, so you ask him to see his inventory in order to help him out. This tutorial assumes that you are using a tutorial-specific The second limitation is more painful: the backend block in Terraform does not allow you to use any variables or references. making changes that appear to be unsafe: Differing lineage: If the "lineage" value in the state differs, your state file before suggesting infrastructure changes. Is it because I answer 'no' in step #3, does this mean it doesn't actually change to which remote state it "points"? This command also works with local state. configuration. In order to complete this tutorial, you will need the following: This tutorial assumes that you are familiar with the Terraform and Terraform I have tried creating it as just a .tf file. Running "terraform apply" again at this point will create a forked state, making it harder to recover. Respond yes to It's pretty much free, durability is excellent as is availability, there's very good native support for it in Terraform using the remote state resource. I also get this. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Even worse, you must very carefully not copy and paste the key value but ensure a unique key for every Terraform module you deploy so that you dont accidentally overwrite the state of some other module! Not the answer you're looking for? You should never edit the Terraform state files by hand or write code that reads them directly. state and execution, structured plan output, workspace resource summaries, and This state file is extremely important; it maps various The state may then be manipulated and subsequently uploaded using the following command, where /path/to/statefile.json is the updated state file. If you are new to Terraform, complete Get Started tutorials first. when working with Terraform. it is managing. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA.

Resource actions are indicated with the following symbols: Terraform will perform the following actions: Plan: 1 to add, 0 to change, 0 to destroy. How can I make the following table quickly? Senate Republican leader Mitch McConnell will be back at work in the U.S. Capitol on Monday, almost six weeks after a fall at a Washington-area hotel and undergoing extended treatment for a concussion. To make this work, you had to use a two-step process: If you ever wanted to delete the S3 bucket and DynamoDB table, youd have to do this two-step process in reverse: This two-step process is a bit awkward, but the good news is that you can share a single S3 bucket and DynamoDB table across all of your Terraform code, so youll probably only need to do it once (or once per AWS account if you have multiple accounts). Lets go through an example. Destroy the infrastructure at the a remote system and resource instances declared in your configuration. I run: At this point, if it's the first time and there is any terraform state at S3 I don't have any terraform.tfstate at local neither at S3. main.tf, this will reconfigure your provider for the us-west-2 region. If you used Terraform Cloud for this tutorial, after destroying your resources, After everything is deployed, you will have an S3 bucket and DynamoDB table, but your Terraform state will still be stored locally. This seems like something Terraform should be more verbose about (I am having to turn up the log level to see that it's not actually initializing an S3 backend as it has been instructed). Sign in . acceptable, you could run a terraform apply -refresh-only and approve the data. For example, run terraform state push | sc terraform.tfstate. pushing state, the destination state will be overwritten. Moreover, its completely managed, so you dont have any infrastructure to run yourself, and its inexpensive, with most Terraform usage easily fitting into the AWS Free Tier. Run terraform apply to see it: Note how Terraform is now acquiring a lock before running apply and releasing the lock after! It is meant only as a utility in case This file contains a custom JSON format that records a mapping from the Terraform resources in your configuration files to the representation of those resources in the real world. Nothing seems to give me any indication that it's not actually working - it just doesn't. How do I undo the most recent local commits in Git? I'm going to close this issue for now, as we have a number of diverging state related questions that aren't necessarily related. This state is stored by default in a local file named "terraform.tfstate", aws_instance.server: Refreshing state [id=i-072ef122350d5a3e5], Note: Objects have changed outside of Terraform. Run terraform plan -refresh-only to review how Terraform would update your state file. This file layout has a number of advantages: In some ways, these advantages are drawbacks, too: In Part 2, An Introduction to Terraform, you used data sources to fetch read-only information from AWS, such as the aws_subnets data source, which returns a list of subnets in your VPC. The combined state is now in place and should be ready for use with a combined configuration. privacy statement. (remove any secrets, of course). The first is that a Terraform command is already running against the state file and it has forced a lock on the file, so nothing breaks. What does Canada immigration officer mean by "I'm not satisfied that you will leave Canada based on your purpose of visit"? @tanmng: if terraform init did nothing, it means it was already initialized somehow from a previous command. git-status - Show the working tree status. => nothing in local, nothing in s3 bucket -refresh-only flag. The opposite is also possible: the terraform state push command allows you to upload a local state file to the configured remote backend. The most common technique for allowing multiple team members to access a common set of files is to put them in version control (e.g., Git). Terraform starts with a single workspace called default, and if you never explicitly specify a workspace, the default workspace is the one youll use the entire time. Usage: terraform state push [options] PATH. your new workspace now. By default, Terraform state is stored locally, which isn't ideal for the following reasons: Local state doesn't work well in a team or collaborative environment. Our guy is not really smart so unless you tell him to add the statue to his inventory, he'll keep trying to deliver a statue and fail. If you were expecting these changes then you can apply this plan to. The reason you need to put so much thought into isolation, locking, and state is that infrastructure as code (IaC) has different trade-offs than normal coding. Having to build a Consul or etcd cluster first without Terraform (otherwise you have a chicken and egg problem of where do you store the state for creating those?) The 81-year-old Kentucky Republican has been recovering at home since he was released from a rehabilitation facility March 25. When moving the folder, make sure that you dont miss the (hidden) .terraform folder when copying files to the new location so you dont need to reinitialize everything. Now, on the other hand, the accepted and upvoted answer on Best practices when using Terraform states: Terraform config can be used to provision many boxes on different infrastructure, each of which could have a different state. local state file) during terraform backend initialization. Replace the Thanks for the tip @tanmng. The text was updated successfully, but these errors were encountered: The value from statefile.config seems to be used ONLY AT FIRST (when I first run terraform init), After that, I have to define the backend within my .tf file to get it to work? the prompt to confirm the operation. Terraform does not push new statefile to S3. The State File Is a Private API. To get proper isolation between environments, instead of workspaces, youll most likely want to use file layout, which is the topic of the next section. GitHub hashicorp / terraform Public Notifications Fork 8.5k Star 36.9k Code Issues 1.6k Pull requests 166 Actions Security 1 Insights New issue #24986 Closed You could have all sorts of infrastructure in your AWS account, deployed through a variety of mechanisms (some manually, some via Terraform, some via the CLI), so how does Terraform know which infrastructure its responsible for? I was able to resolve following the instructions from @roberthstrand So, this State File contains all the information of the resources which we created using our Terraform code. commands will detect it and remind you to do so if necessary. As a workaround, you can continue use newer terraform version(s), but you need to execute $ terraform state push terraform.tfstate.backup after running $ terraform init. @AllaeddineEL: I don't think any of the above were having trouble migrating from local state. Before moving on, make sure to clean up the three EC2 Instances you just deployed by running terraform workspace select and terraform destroy in each of the three workspaces. I recently upgrade to 0.9.5 and I have the same issue. when i am running my new code pointing it to the terraform.tfstate file from the old deployment then i am getting prompted for Plan: 26 to add, 0 to change, 25 to destroy. That means you use the same authentication and access controls for all the workspaces, which is one major reason workspaces are an unsuitable mechanism for isolating environments (e.g., isolating staging from production). This tutorial assumes that you are familiar with the Terraform workflow. There are a few reasons not to store your .tfstate files in Git: For more info, check out How to manage Terraform state and Terraform: Up & Running, both of which I wrote. Install and configure Terraform Get Started Install and configure Terraform; Install the Azure Terraform Visual Studio Code extension; Authenticate Terraform to Azure; Store Terraform state in Azure Storage You still have to be very careful who on your team can access the S3 bucket, but at least the data will be encrypted at rest (Amazon S3 supports server-side encryption using AES-256) and in transit (Terraform uses TLS when talking to Amazon S3). Why is a "TeX point" slightly larger than an "American point"? This gives you a 1:1 mapping between the layout of your Terraform code in version control and your Terraform state files in S3, so its obvious how the two are connected. Terraform will perform a number of safety checks to prevent you from After apply completes, you should see the outputs in the terminal: These outputs are now also stored in the Terraform state for the database, which is in your S3 bucket at the path stage/data-stores/mysql/terraform.tfstate. Terraform will not allow you to push the state. Now that you have reviewed the behavior of the -refresh-only flag, you will Terraform Cloud variable set configured with your AWS credentials, Troubleshoot common issues with Terraform. Use, to view the state list information from the state in the backend, which was just pushed. Study the complete list of study materials (including docs) in the Certification Prep guides. Now, head over to the S3 console again, refresh the page, and click the gray Show button next to Versions. Merging two states involves moving resources from one to the other using using terraform state mv [options] SOURCE DESTINATION [a]. How to turn off zsh save/restore session in Terminal.app. We are not responsible for any deleting an object that you asked Terraform to "forget", or by re-importing it From my understanding the "correct" way to do this in powershell is to use the Out-File cmdlet with the -Encoding UTF8NoBOM option. All resources should now exist in the destination state, which can be checked similarly with, . Use the Terraform Command Line Interface (CLI) to manage infrastructure, and interact with Terraform state, providers, configuration files, and Terraform Cloud. ensure for yourself that this one-to-one rule is followed, such as by manually I have added the backend configuration in my "main.tf" file as: I provide the environment and the id in each execution because are used to configure S3, that's why I need to configure the backend in each execution. resources you created earlier are still in us-east-2. Youll see the full details of ternary syntax and conditional logic in Part 5 of this series. I have tried to create my statefile.config in all different directories. If the modifications to your state file proposed by a -refresh-only plan were review any modifications. After the resources creation complete, there will be file created called terraform.tfstate. I will move resources from, . However, the state format is subject to change in new Terraform versions, so Heres the file layout for my typical Terraform project: At the top level, there are separate folders for each environment. The exact environments differ for every project, but the typical ones are as follows: Within each environment, there are separate folders for each component. The components differ for every project, but here are the typical ones: Within each component, there are the actual Terraform configuration files, which are organized according to the following naming conventions: When you run Terraform, it simply looks for files in the current directory with the .tf extension, so you can use whatever filenames you want. project will keep the CLI working while the state format underneath it may Find centralized, trusted content and collaborate around the technologies you use most. result as an artifact associated with the automated run so that other software Try running terraform apply to deploy this second EC2 Instance in the new workspace: Repeat the exercise one more time and create another workspace called example2: Run terraform apply again to deploy a third EC2 Instance: You now have three workspaces available, which you can see by using the terraform workspace list command: And you can switch between them at any time using the terraform workspace select command: To understand how this works under the hood, take a look again in your S3 bucket, you should now see a new folder called env: Inside the env: folder, youll find one folder for each of your workspaces: Inside each of those workspaces, Terraform uses the key you specified in your backend configuration, so you should find an example1/workspaces-example/terraform.tfstate and an example2/workspaces-example/terraform.tfstate. This helps our maintainers find and focus on the active issues. Terragrunt can help you keep your entire backend configuration DRY (Dont Repeat Yourself) by defining all the basic backend settings (bucket name, region, DynamoDB table name) in one file and automatically setting the key argument to the relative folder path of the module. In what context did Garak (ST:DS9) speak of a lie between two truths? If changes are proposed and this is unexpected, then review the changes to determine the next steps. You also reviewed the implicit refresh behavior in standard Update the Terraform code to now refer to container terraforminfra-v2. A differing lineage Afterward, I can now use my terraform version 0.9.2 without issues. For an expanded version of this blog post series, pick up a copy of the book Terraform: Up & Running (3rd edition available now!).
