Adding function environment variables

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To add environment variables, run the command:

yc serverless function version create \
  --function-name=<function_name> \
  --runtime <runtime_environment> \
  --entrypoint <entry_point> \
  --memory 128m \
  --execution-timeout 5s \
  --source-version-id <version_ID> \
  --environment <environment_variables>

Where:

• --function-name: Function name.
• --runtime: Runtime environment.
• --entrypoint: Entry point in <function_file_name>.<handler_name> format.
• --memory: Amount of RAM.
• --execution-timeout: Maximum function running time before timeout.
• --source-version-id: ID of the function version from which you want to copy the code.
• --environment: Environment variables in key=value format. You can specify multiple pairs separated by commas.

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the relevant documentation on the Terraform website or its mirror.

If you do not have Terraform yet, install it and configure the Yandex Cloud provider.

To add environment variables:

1. In the configuration file, add the environment section for the yandex_function resource and specify the list of environment variables as <key> = "<value>".

   Example of a function description in the Terraform configuration:

   resource "yandex_function" "test-function" {
       name               = "test-function"
       description        = "Test function"
       user_hash          = "first-function"
       runtime            = "python37"
       entrypoint         = "main"
       memory             = "128"
       execution_timeout  = "10"
       service_account_id = "<service_account_ID>"
       tags               = ["my_tag"]
       environment = {
           <environment_variable_key> = "<environment_variable_value>"
       }
       content {
           zip_filename = "<path_to_ZIP_archive>"
       }
   }
   

   For more information about yandex_function properties, see this Terraform article.

2. Check the configuration using this command:

   terraform validate
   

   If the configuration is correct, you will get this message:

   Success! The configuration is valid.
   

3. Run this command:

   terraform plan
   

   You will see a detailed list of resources. No changes will be made at this step. If the configuration contains any errors, Terraform will show them.

4. Apply the changes:

   terraform apply
   

5. Confirm the changes: type yes into the terminal and press Enter.

You can check the new environment variables using the management console.

To add environment variables, use the createVersion REST API method for the Function resource or the FunctionService/CreateVersion gRPC API call.
