Mounting buckets to a container

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

The folder used by default is the one specified when creating the CLI profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also specify a different folder for any command using --folder-name or --folder-id. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.

Run this command:

yc serverless container revision deploy \
  --container-name <container_name> \
  --image <Docker_image_URL> \
  --memory <RAM_size> \
  --execution-timeout <execution_timeout> \
  --service-account-id <service_account_ID> \
  --command '<command_1>','<command_2>' \
  --args '<key_1=value_1>','<key_2=value_2>' \
  --mount type=object-storage,mount-point=<mount_path>,bucket=<bucket_name>,prefix=<directory_name>,mode=<mount_mode>

Where:

• --container-name: Container name.

• --image: URL of the Docker image you are creating a container revision from in the following format: cr.yandex/<registry_ID>/<Docker_image_name>:<tag>.

• --memory: Required RAM.

• --execution-timeout: Maximum container execution time before timeout.

• --service-account-id: Service account ID. The service account needs the storage.viewer role for bucket read access or the storage.uploader role for both read and write access.

• --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 skip this setting, the default CMD value from the Docker image will be used.

• --mount: Object Storage bucket mount settings:

  • type: Mounted storage type. For a bucket, the value is always object-storage.
  • mount-point: Absolute mount path. Use this path to access the directory the bucket will be mounted to.
  • bucket: Bucket name.
  • prefix: Bucket folder that will be mounted to the container. Skip this field or leave it empty to mount the entire bucket.
  • mode: Bucket mount mode, ro (read-only) or rw (read and write).

  To mount several buckets to a container at the same time, specify --mount as many times as you need.

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 manage infrastructure using Terraform under a service account or user accounts (a Yandex account, a federated account, or a local user), authenticate using the appropriate method.

1. Open the Terraform configuration file and add the mounts section to the container description:

   resource "yandex_serverless_container" "test-container" {
     ...
   
     mounts {
       mount_point_path = "<mount_point>"
       mode             = "<mount_mode>"
       object_storage {
         bucket = "<bucket_name>"
         prefix = "<directory_name>"
       }
     }
   }
   

   Where:

   • mounts: Object Storage bucket mount settings:

     • mount_point_path: Absolute mount path. Use this path to access the directory the bucket will be mounted to.
     • mode: Bucket mount mode, ro (read-only) or rw (read and write).
     • object_storage: Bucket settings:
       • bucket: Bucket name.
       • prefix: Bucket folder that will be mounted to the container. Leave this field empty to mount the entire bucket.

     To mount several buckets to a container at the same time, specify mounts as many times as you need.

   For more information about yandex_serverless_container properties, see this provider guide.

2. Apply the changes:

   1. In the terminal, navigate to the configuration file directory.

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

      terraform validate
      

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

      Success! The configuration is valid.
      

   3. Run this command:

      terraform plan
      

      You will see a list of resources and their properties. No changes will be made at this step. Terraform will show any errors in the configuration.

   4. Apply the configuration changes:

      terraform apply
      

   5. Type yes and press Enter to confirm the changes.

You can check the container revision update and its settings using the management console or this CLI command:

yc serverless container revision get <container_revision_ID>

Use the deployRevision REST API method for the Container resource or the ContainerService/DeployRevision gRPC API call.
