How to find out your COI version
  • For version 2.0.4 and higher, run this command to get the version from inside the image:

    cat /etc/ycloud/image-info
    

    Result:

    coi-version: 2.3.14
    
  • For version 2.1.0 and higher, run this command to get the version in description:

    yc compute image get-latest-from-family container-optimized-image \
      --folder-id standard-images --format json \
    | jq -r '.description'
    

    Result:

    Container Optimized Image 2.3.14
    

Note

In version 2.2.0 and higher, the patch, which is the third number in the version, such as 3 in 1.2.3, means an update of the system components and packages and is not there in the release list.

Version 3.1.0

  • Container Optimized Image is now available in the Kazakhstan region. To work with Docker images as a service account linked to a VM with a running Container Optimized Image, you will be using Delphi Container Registry of the same region as the VM.
