Hello i would you grateful for your help. How to change port is being used by com.docker.backend ? Before run container port 8080 is not used. When i tried kill process it causes closing “docker desktop”. Please help.

You can see the container using You can remove it with docker rm -f <container-id>.

I don’t know what process you killed, but think Docker Desktop wouldn’t use a port like that unless you have a Docker Desktop extension. An extensio is basically a container that runs in the background and you don’t even see it in the list of containers by default. That behavior can be changed by setting “Show Docker Extensions system containers” in “Settings » Extensions”
