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

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

1. View a 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 a file named docker-compose.yaml:

   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. It must be at least 30 GB.
   • --network-interface: VM network settings.
   • --service-account-name: Name of the service account.
   • --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 via SSH.

   2. View a list of running Docker containers:

      sudo docker ps -a
      

      Result:

      CONTAINER ID  IMAGE  COMMAND                 CREATED         STATUS         PORTS               NAMES
