Creating a container revision

To create a container revision, run this command:

yc serverless container revision deploy \
  --container-name <container_name> \
  --image <Docker_image_URL> \
  --cores 1 \
  --memory 1GB \
  --concurrency 1 \
  --execution-timeout 30s \
  --service-account-id <service_account_ID> \
  --command '<command_1>','<command_2>' \
  --args '<key_1=value_1>','<key_2=value_2>'

Where:

• --cores: Number of cores available to the container.

• --memory: Required memory. The default value is 128 MB.

• --concurrency: Maximum number of concurrent requests to a single container instance. May be in the range between 1 (default) and 16. If the number of requests to a container exceeds the concurrency value, Serverless Containers scales the container up by running its additional instances.

  Note

  The number of container instances and concurrent container requests in each zone cannot exceed the quota.

• --execution-timeout: Timeout. The default value is 3 seconds.

• --service-account-id: ID of the service account with permissions to download a Docker image.

• --command: Commands the container will run when started. Separate them by commas. It matches the ENTRYPOINT instruction in the Dockerfile.

• --args: Arguments matching the CMD instruction in the Dockerfile. Specify them in key = value format separated by commas. If you do not specify this parameter, the default CMD value from the Docker image will be used.

Result:

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.

In Terraform, a new revision is created every time the resource runtime parameters are updated.

To create a revision:

1. Update the parameters of the yandex_serverless_container resource in the configuration file:

   resource "yandex_serverless_container" "test-container" {
     name               = "<container_name>"
     cores              = "<number_of_cores>"
     memory             = "<memory_amount>"
     concurrency        = "<concurrent_requests>"
     service_account_id = "<service_account_ID>"
     image {
       url      = "<Docker_image_URL>"
       command  = ["<command_1>","<command_2>"]
       args     = ["<key_1=value_1>","key_2=value_2"]
       work_dir = "<working_directory>"
     }
   }
   

   Where:

• cores: Number of cores available to the container.

• memory: Required memory. The default value is 128 MB.

• concurrency: Maximum number of concurrent requests to a single container instance. May be in the range between 1 (default) and 16. If the number of requests to a container exceeds the concurrency value, Serverless Containers scales the container up by running its additional instances.

  Note

  The number of container instances and concurrent container requests in each zone cannot exceed the quota.

• command: Commands the container will run when started. Separate them by commas. It matches the ENTRYPOINT instruction in the Dockerfile.

• args: Arguments matching the CMD instruction in the Dockerfile. Specify them in key = value format separated by commas. If you do not specify this parameter, the default CMD value from the Docker image will be used.

• work_dir: Allows you to change the working directory of a container. It matches the WORKDIR instruction in the Dockerfile. We recommend setting absolute paths to folders.

For more information about the yandex_serverless_container parameters in Terraform, see the relevant provider documentation.

1. Create resources:

   1. In the terminal, change to the folder where you edited the configuration file.

   2. Make sure the configuration file is correct using the command:

      terraform validate
      

      If the configuration is correct, the following message is returned:

      Success! The configuration is valid.
      

   3. Run the command:

      terraform plan
      

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

   4. Apply the configuration changes:

      terraform apply
      

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

   This will create the revision. You can check the new revision using the management console or this CLI command:

   yc serverless container revision list
   

To create a container revision, use the deployRevision REST API method for the Container resource or the ContainerService/DeployRevision gRPC API call.
