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 specified when creating the CLI profile is used by default. To change the default folder, use the yc config set folder-id <folder_ID> command. You can specify a different folder using the --folder-name or --folder-id parameter.

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

1. View the description of the CLI command to create a VM from a Container Optimized Image:

   yc compute instance create-with-container --help
   

2. Create 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 default-sa \
     --docker-compose-file docker-compose.yaml
   

   Where:

   • --name: VM name.

   • --zone: Availability zone.

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

   • --docker-compose-file: YAML file with 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 via SSH.

   2. View a list of running Docker containers:

      sudo docker ps -a
      

      Result:

      CONTAINER ID  IMAGE  COMMAND                 CREATED         STATUS         PORTS               NAMES
