Creating a VM from a Container Optimized Image with multiple Docker containers

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.

To create a VM from a Container Optimized Image with multiple Docker containers:

1. See the description of the CLI command for creating a Container Optimized Image VM:

   yc compute instance create-with-container --help
   

2. Set up a Docker container specification. Save the following data to the docker-compose.yaml file:

   version: '3.7'
   services:
     app1:
       container_name: nginx
       image: "nginx"
       ports:
         - "80:80"
       restart: always
     app2:
       container_name: redis
       image: "redis"
       restart: always
   

3. Create a VM with multiple Docker containers:

   yc compute instance create-with-container \
     --name my-vm \
     --zone ru-central1-a \
     --ssh-key ssh-key.pub \
     --create-boot-disk size=30 \
     --network-interface subnet-name=<subnet_name>,nat-ip-version=ipv4 \
     --service-account-name <service_account_name> \
     --docker-compose-file docker-compose.yaml
   

   Where:

   • --name: VM name.

   • --zone: Availability zone.

   • --ssh-key: Path to the public key file and file name.

   • --create-boot-disk size: Boot disk size.

     To get the minimum boot disk size required for installing an image, run this command:

     • yc compute image get-latest-from-family container-optimized-image --folder-id standard-images if you are installing a Container Optimized Image.
     • yc compute image get-latest-from-family container-optimized-image-gpu --folder-id standard-images if you are installing a GPU Container Optimized Image.

     You can find the minimum boot disk size in the min_disk_size property.

   • --network-interface: VM network settings.

   • --service-account-name: Name of the service account you created earlier.

   • --docker-compose-file: YAML file with the container specification.

   Once created, the VM will appear in the VM list under Compute Cloud in the management console.

4. Check the result.

   1. Connect to the VM over SSH.

   2. View the list of running Docker containers:

      sudo docker ps -a
      

      Result:

      CONTAINER ID  IMAGE  COMMAND                 CREATED         STATUS         PORTS               NAMES
