What is Terraform Cloud Remote Operations?

Terraform Cloud Remote operations are the way that Terraform Cloud lets you run your Terraform workflows from your local machine. You might ask, “What is the point? Why not just run Terraform locally?” Well, this feature gives you the best of both worlds: the flexibility of working locally with the power and consistency of Terraform Cloud. This means you get to keep using your favorite tools while being sure that your infrastructure changes follow team-wide rules and are tracked for history.

It’s a big step up from just running things on your own. With this feature you and your team can standardize processes and avoid the dreaded “it works on my machine” problem. Think of it as a bridge between your local setup and the managed environment of Terraform Cloud. This approach gives you a good balance of control and the perks of a collaborative, cloud-based tool.

Why Use Terraform Cloud Remote?

There are some good reasons why using Terraform Cloud Remote should be a consideration for your team. Here are some benefits:

Collaboration and Consistency

The biggest win is how much easier it is to work as a team. Every single plan and apply runs in the same environment. This means all members of your team are using the same versions of Terraform and providers. This prevents those odd bugs that happen because of environment differences. It also means you can set policies for all operations. So you ensure that changes follow the standards you have as a team.

Centralized State Management

Terraform Cloud takes care of managing your Terraform state files. You will not have to worry about locking, or potential problems with local state files. This central state keeps your deployments more reliable. It helps prevent accidents that might occur if many people work on the same project.

Security and Access Control

With this setup, you can use specific permissions to control who can run plans and apply changes. It’s more secure than handing out credentials to each member of the team. This is a step up in controlling who can touch what in your infrastructure. You can also monitor all actions through the platform.

Automation and Pipelines

Terraform Cloud can integrate with the systems you use for your CI/CD pipelines. This can fully automate your infrastructure changes. It is a good thing to have everything from code changes to infrastructure updates flow together automatically, with very little manual involvement.

How Remote Operations Work

The flow of remote operations is not too hard to follow. Here is a breakdown:

Local Configuration: You start by writing and setting up your Terraform config on your local machine. This is where you define all of the things you want to build.
Connecting to Terraform Cloud: You use the Terraform CLI to connect to your Terraform Cloud organization and workspace. This tells Terraform where your work will be run.
Starting a Remote Plan: You run the terraform plan command. This does not apply anything to the real world. Instead, it sends your config to Terraform Cloud. This will run the plan in a remote environment.
Reviewing the Plan: Terraform Cloud does the plan in a controlled environment, and then provides a result of the plan. This tells you what changes it will make to the real-world infrastructure. You can review this plan from your local machine. Or from the Terraform Cloud UI.
Applying Changes: When you are sure everything is correct, you use the terraform apply command. This sends the request to Terraform Cloud. Then, Terraform Cloud will apply the changes.
Remote Execution: All of the execution and changes happen on the Terraform Cloud servers. Not on your machine. This makes your process more consistent and reliable.
State Storage and Tracking: Terraform Cloud keeps track of all your infrastructure details. So you know at any time what is running. And what has changed. You have a full audit trail to view.
Output and Results: You receive the output of the operations on your local terminal. You will also be able to check all results and logs in Terraform Cloud.

This process means that you don’t need to have any infrastructure knowledge to use Terraform. If you can write a few commands in your terminal, you have the power to deploy infrastructure. This helps democratize DevOps. And also empowers each member of the team to understand and control their deployments.

Setting Up Terraform Cloud Remote Operations

Getting set up to use Remote Operations needs a few initial steps. Here’s what you need to do:

Install Terraform CLI

You will need the Terraform CLI installed on your machine. You will use this command line to run your plan and apply commands.

Download the correct version of the Terraform CLI for your system from the official website.
Follow the install instructions that are on the Terraform website.
After the install, you can verify that the installation worked. Use the command terraform --version

Create a Terraform Cloud Account and Organization

If you do not have one already, you’ll need to create a Terraform Cloud account. After you have an account, you’ll create an organization. Your team will work under this organization.

Go to the Terraform Cloud website and register for an account. You may need to use a company email, or a specific email type. This will depend on your company policies.
After you log in, you will need to create your organization. You will set its name. And other settings to fit your company needs.

Configure a Workspace

You will set up a workspace inside of your organization. This will be the logical location where you will keep your resources.

In your Terraform Cloud account, create a new workspace.
You will choose the type of version control. If you are using Git or a similar system.
You will connect your workspace to a specific repository or branch on that system. If you are using a local method, it might be a different set up.
Set the workspace settings to match what you are trying to do. You can change the name. You will need to add variables that your configuration needs, and other such changes.
You can also set up specific rules for this workspace, such as which users can have access, or which plan needs an approval.

Authenticate Your Local Environment

You will connect your local CLI to your Terraform Cloud account through authentication.

Go to your user settings in Terraform Cloud to get an API token.
Use the terraform login command in your terminal, and enter the API token you have just created.
You can verify that you are connected by running a terraform cloud command.

Key Commands for Remote Operations

Knowing how to use the Terraform CLI to connect to Terraform Cloud will empower you. These are some important commands you need to understand:

`terraform init`

This command will initialize your Terraform configuration. This process will download the plugins and providers your configuration needs. You’ll do this from your local machine.
* This command should be the first command you run in a new configuration directory. It makes sure that your setup is good to go.

`terraform plan`

This is one of the main commands to run your plan in the cloud. This command will start the remote plan. It will show you all of the changes it will perform in your infrastructure.

It is important to use this command every time you change your Terraform configuration. It helps you prevent unwanted or bad changes from occurring.
You can also use the -out option to keep this plan as a file. You will use this file in the next step to apply.

`terraform apply`

This command will apply all of your changes. It will use the plan you created in the previous step. Or by default, it will prompt you to confirm that you want to apply changes.

You can also use a plan file as an input to this command using the specific command terraform apply <plan file>.

`terraform state`

This command lets you manage your state files. You can use this to perform operations such as list, show, mv, and rm. This can also help you debug.

You can use this to inspect your state, or to make changes in the state of your resources. This can be done when you have an issue that you need to resolve.

`terraform cloud`

This command is what you will use to interact with your Terraform Cloud workspace and organization.

You can use the command terraform cloud workspace list to view all of your workspaces.
You can also use it to get the current login status using terraform cloud login.

Best Practices for Terraform Cloud Remote Operations

Here are a few best practices that you should follow:

Use Version Control

Always keep your Terraform configuration in a version control system. This makes it easier for teams to collaborate. It also helps you keep a record of all of the changes you’ve made over time. It makes changes easy to review, and helps you roll back to prior versions when needed.

Create a Git repository for your Terraform configuration.
Keep all changes as small commits to make it easy to follow your changes.
Use branches to develop features, and keep the main branch as the official working version.

Use Modules

When you use modules, it lets you make reusable components of your infrastructure. This will keep your code clean and easy to manage.
* Create a module for parts of your infrastructure that you use again and again.
* Use modules that others have made. Look at the Terraform Registry to see if there are any good modules that fit your needs.
* Keep your modules up to date. When you update a module, you should make sure you update the versions in all the places that it is used.

Use Variables

You can use variables to keep your configuration flexible and secure. This means that you will not hard-code values into your configuration. It also means that you can configure settings in one place. It is a good idea to use environment variables.
* Set variables for values that can change. Examples would be regions, instance sizes, and passwords.
* Keep secret information as sensitive variables. You can store these in Terraform Cloud.
* Use different variables for development, test, and production. This makes it easier to keep each environment separate.

Plan Before You Apply

Always run a terraform plan and review the output carefully before you apply. This will help prevent unexpected changes that may affect your infrastructure negatively.
* Share the plan output with your team. This is an opportunity for review and input.
* When using automated tools, integrate a plan check before an apply step.
* Always look closely at any destructive changes that a plan will make.

Manage State Carefully

Terraform Cloud handles your state by default. However you should also be aware of how the state is managed.

Lock the state files when changes are occurring. This will prevent two people from making changes at the same time.
Do not modify the state manually if you can help it.
If there is an issue with the state, research the correct way to make the change.

Use Remote Backends

Remote backends are a big part of Terraform Cloud. This will be managed by default when you use Terraform Cloud. This is where all state files will be stored.
* Using a remote backend, keeps your state safe and accessible to all of your team.
* This helps with consistency since everyone on your team will use the same state file.
* This is also a great step for security, since it prevents you from accidentally storing state information locally or in an insecure location.

Lock Down Permissions

Make sure to use role based access control so that you control who can make changes to your infrastructure.
* Use different roles for different team members.
* Give users only the access they need.
* You can review access rights regularly.

Automate Your Pipeline

Automate your workflows to run automatically when you push to your git repositories. This will save you a lot of time and effort, and also reduce human errors.

Set up CI/CD to run terraform plan on every commit to the main branch.
Add an approval step before applying changes.
Use Terraform Cloud APIs to interact with other tools.

Monitor and Log Operations

It is a good idea to monitor your Terraform operations. You should keep logs of all changes that are made in your infrastructure. This will help you troubleshoot and keep an audit trail.

Use the Terraform Cloud UI to keep track of all of the plan and apply operations.
Connect your logs to a centralized logging tool.
Set up alerts for any unexpected changes.

Keep Your Environment Clean

Use the terraform destroy command to remove any resources you do not need.

This can save you a lot of money.
You can also automate a process of removing development resources once you are finished using them.

Continuously Improve

Make sure you are using the newest version of Terraform, and other providers. This can help with security fixes, new features, and performance upgrades.

Update Terraform CLI and providers regularly.
Keep up with the best practices in the Terraform world.
Participate in Terraform community forums to stay informed.

Troubleshooting Common Issues

Even with best practices, you might face some issues. Here are common problems and how to solve them:

Authentication Errors

If you are having errors when trying to connect to Terraform Cloud, these steps should help.

Confirm your API token is valid and up to date.
Make sure the user that is used for the API token has the correct permissions.
Use the command terraform login again to refresh the login.
You can test the connection using terraform cloud login.

State File Locking

If your state is locked, it may be because another change is occurring at the same time.

Check who locked the state file. You can unlock it manually if needed.
Wait for the current change to finish.
Avoid making changes on the same resource at the same time.

Provider Version Issues

If you are seeing errors about provider version, then there is an issue with the version of the providers you are using.

Confirm that all members of your team are using the same version.
Update the provider version in your terraform block.
Run terraform init again to update the provider.

Unexpected Plan Changes

If your plan has changes that you do not understand, you will need to investigate further.

Use the terraform plan command to review any changes.
Check the configuration to confirm you have set everything correctly.
Check the logs to see when the change was initiated.
Review provider documentation to see if there have been changes.

Connectivity Problems

If you cannot connect to Terraform Cloud from your local environment, you should follow these steps:

Check your network settings.
Make sure that you can reach the Terraform Cloud servers.
If you are using a proxy, make sure it is set correctly.
Test the connection from a different network.

Permissions Issues

If you are getting permission errors, then your user may be missing the correct roles.
* Review the permission on Terraform Cloud to make sure you have the right role.
* Ask your administrator to grant the correct permissions.
* Try running the command as a different user if you have permission.

If you are getting an error that is not on this list, make sure to check the logs. The error message might point to the solution. You can also check the Terraform documentation. There may be a specific answer for your issue. If all else fails, check the community forums. Others may have had similar issues, and found a solution.
