[dnull88]

i try use portus on kubernetes (minikube). DB,Registry,portus is up. Authentication (as docker login) works, webhook-notification works. When i try delete tag by portus - i receive "... unable to be removed." In registry log:

Could not delete tag on the registry: execution expired
Completed 500 Internal Server Error in 2025ms (ActiveRecord: 4.7ms)

delete enabled in registry and portus. Registry version - 2.6, Portus version - 2.3.0-dev
Same configuration works on docker-compose (with same envs,certs,images).
Maybe someone can help with this problem?

Here's your problem: Could not delete tag on the registry: execution expired. In the source code of Portus we have a timeout of 2 seconds for any HTTP request, which includes the registry (see this line). So, I'd start investigating why is it so slow (if you could login with docker, then I assume that the registry is reachable at some point).

It's also worth mentioning that this timeout value is quite magical (at the time we thought it was enough, but maybe this isn't always the case). So another solution would be to increase it (or even make it configurable). That being said, I'd like to know why is it so slow...

Would it be possible for you to increase this value, and check which is the timeout value that works for you ?

Closing due to inactivity. I believe that we have polished this feature quite a lot. Otherwise, there's an issue (#1599) that might relate a bit with these kinds of issues.
