Adding container 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 container revision deploy \
  --container-name <container_name> \
  --image <Docker_image_URL> \
  --cores 1 \
  --memory 1GB \
  --service-account-id <service_account_ID> \
  --environment <environment_variables>

Where:

• --cores: Number of cores available to the container.
• --memory: Required memory. The default value is 128 MB.
• --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. Open the Terraform configuration file and add a list with environment variables named environment to the image section for the yandex_serverless_container resource:

   ...
   resource "yandex_serverless_container" "test-container" {
     name               = "my-container"
     memory             = 256
     service_account_id = "ajecvjv1lv01********"
     image {
         url = "cr.yandex/yc/test-image:v1"
         environment = {
             <key> = "<value>"
         }
     }
   }
   ...
   

   Where environment represents environment variables in key="value" format. You can specify more than one pair.

   For more information about the yandex_serverless_container resource parameters in Terraform, see the relevant 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 or this CLI command:

yc serverless container revision get <revision_ID>

To add an environment variable, use the deployRevision REST API method for the Container resource or the ContainerService/DeployRevision gRPC API call.
