Questions and answers about Container Solution

How do I perform auto updates based on immutable tags?

Updating a container won't work with tags that persist from version to version. We recommend using a new tag for each Docker image.

Disadvantages of using tags that persist from version to version:

• When a problem occurs, it's difficult to find its source if several identical VMs have the same tag but different code.
• A cluster of multiple VMs can be heterogeneous, for example, if one VM restarts and updates a Docker image.
• It's difficult to distinguish between Docker image versions on a VM.
