How Do I Export My State from Spacelift Using Terraform?

Question:

I am using Spacelift and my stack’se state is managed by it, but now I need to export this state data into an Amazon S3 bucket for backup purposes or other reasons. How can that be achieved without altering the current setup too much?

Accepted Answer:

Certainly! You have a couple of options using Terraform commands integrated with Spacelift, which will help you pull and export your state file to an Amazon S3 bucket seamlessly. Here’s how it can be done through tasks or by configuring hooks for regular execution:

Using Task Commands in the Interactive Console

1. Firstly, extract (pull) your current Terraform state into a JSON format using this command within Spacelift’s interactive console (CLI):

   terraform state pull > state.json && echo "export complete" | at -M now +30m >> my_statebackup.log
   

2. Then, use the AWS CLI to copy (cp) state.json into your specified S3 bucket:

   aws s3 cp state.json s3://my-unique-bucket/path-to-your-folder/ --acl public-read # Adjust ACL as needed for security or access permissions
   

   Please make sure that the AWS credentials are configured, and Spacelift stack has proper write permission to your S3 bucket. You can check this by referring to Spacelift’s documentation on integrating with cloud providers.

Alternatively, for a more automated approach:

Setting Up Hook in Workflow Configuration

1. Navigate to your Spacelift stack settings and access the Hooks tab from there under ‘Workflow configuration’.
2. Create or select an existing hook which triggers when you want this state export process, for example during a nightly backup task:
3. Add commands within that Hook’s execution script to pull your Terraform’s current state and then copy it into S3 using the AWS CLI as shown above—or any similar command depending on how frequently or at what event (like successful deployment) you want this operation executed. This way, Spacelift will automatically run these commands under defined conditions without manual intervention each time a workflow triggers that hook during your specified execution window.

Remember to adjust permissions and secure the necessary AWS credentials properly for seamless integration between Terraform’s state file export operations in Spacelift with S3 storage solutions, maintaining best practices around security configurations when storing sensitive data like infrastructure states externally on cloud services such as Amazon Web Services.
