🌍 Exporting Environment Variables In Custom Flow

Custom flows are an essential and important feature in the env0 platform, and today we released a new and powerful enhancement to declare environment variables that are persistent between commands and steps in the env0.yml file, and can be used either by other Terraform/Terragrunt commands or in other custom flow commands.

✨ Export your own Environment Variables ✨

In the env0.yml steps, append your key-value to the $ENV0_ENV file, like so: echo KEY=VALUE >> $ENV0_ENV. You may do so explicitly, in a separate command, or within your own script. The value can be accessed in any later step, explicitly in a command or within a script.

✨ Export your own TF_VAR ✨

Using this feature you may also export Terraform environment variables. The key should use the TF_VAR_ prefix, as mentioned in the official Terraform documentation (See this for more details)

🚧

Note

When declaring an environment variable in deploy, it won't be recognized in destroy and vice versa.

Check out this example template that demonstrates the use of TF_VAR and $ENV0_ENV.

You can read more about this feature in our official docs: https://docs.env0.com/docs/custom-flows#exporting-your-own-environment-variables

This feature is also available in our Self hosted as agent in version >= v3.0.33.
