Adding function environment variables

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder 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 the timeout is reached.
• --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.

Terraform allows you to quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. Configuration files store the infrastructure description in the HashiCorp Configuration Language (HCL). Terraform and its providers are distributed under the Business Source License.

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

If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

If you don't have Terraform, 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 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 the yandex_function resource properties, see the provider documentation.

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
   

   The terminal will display a list of resources with parameters. No changes will be made at this step. If the configuration contains any errors, Terraform will point them out.

4. Apply the configuration 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.

You can add environment variables using the Yandex Cloud Toolkit plugin for the IDE family on the JetBrains IntelliJ platform.
