What can happen if my delegates aren't updated?

You can encounter some strange errors if your delegates are expired. In most cases the delegate will still function as expected but you might encounter some hard to diagnose issues if running an older delegate.

See the below to see if you’re running the supported version or if the version you are running is expired.

Harness has an N-3 support policy for delegates. N-3 means that the current version and the three previous versions are supported.

You can use the API to determine the latestSupportedVersion for your account

Alternatively in the UI you can also check under Account Settings > Account Resource > Delegates

If you cannot use dockerhub or harness internal docker registry due to internal security policies, you can use the API to list the latest supported version to your internal repository and then use it to supply the upgrader with a custom delegate tag
