Creating a VM from a Container Optimized Image and an additional volume for a Docker container

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.

1. View a description of the CLI create VM command:

   yc compute instance create-with-container --help
   

2. Prepare the Docker Compose specification. Save the following data to a file named docker-compose.yaml:

   version: '3.4'
   services:
     app2:
       container_name: container-name
       image: "mongo:latest"
       ports:
         - "27017:27017"
       restart: always
       volumes:
         - /home/yc-user/coi-data:/data
   x-yc-disks:
     - device_name: coi-data
       fs_type: ext4
       host_path: /home/yc-user/coi-data
   

   When creating your VM via the CLI, a default user is created: yc-user.

3. Create a VM with multiple disks:

   yc compute instance create-with-container \
     --name coi-vm \
     --zone ru-central1-a \
     --create-boot-disk size=30 \
     --create-disk name=data-disk,size=10,device-name=coi-data \
     --network-interface subnet-name=<subnet_name>,nat-ip-version=ipv4 \
     --ssh-key <path_to_the_public_part_of_the_SSH_key> \
     --docker-compose-file docker-compose.yaml
   

   Where:

   • --name: VM name.
   • --zone: Availability zone.
   • --create-boot-disk: Parameters of the VM disk. The disk size must be at least 30 GB.
   • --network-interface: Network parameters:
     • subnet-name: Name of the subnet to host the VM.
     • nat-ip-version: Public IPv4 address assignment method.
   • --ssh-key: Path to the file with the public key.
   • --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. Get the ID of the running Docker container:

      sudo docker ps -a
      

      Result:

      CONTAINER ID  IMAGE         COMMAND                 CREATED        STATUS        PORTS      NAMES
      1f71********  mongo:latest  "docker-entrypoint.s…"  5 minutes ago  Up 5 minutes  27017/tcp  container-name
      

   3. Connect to the running Docker container:

      sudo docker exec -it 1f71******** bash
      

   4. View the list of attached disks. Take note of the /dev/vdb 11G 24M 9.9G 1% /data mounted disk:

      df -H
      

      Result:

      Filesystem  Size  Used  Avail  Use%  Mounted on
      overlay     32G   4.0G    27G   14%  /
      tmpfs       68M      0    68M    0%  /dev
      ...
      tmpfs       1.1G     0   1.1G    0%  /proc/acpi
      tmpfs       1.1G     0   1.1G    0%  /proc/scsi
      tmpfs       1.1G     0   1.1G    0%  /sys/firmware
