Additional context

I take the Auth Config from docker login and put it in config.json.

I also have the Problem, i download ex. the Watchtower Image from DockerHub over DSM and in Watchtower i become this error:

2023/07/27 16:32:27 | stderr | time="2023-07-27T14:32:27Z" level=debug msg="No credentials for containrrr found" config_file=/config.json
2023/07/27 16:32:27 | stderr | time="2023-07-27T14:32:27Z" level=debug msg="Trying to load authentication credentials." container=/watchtower image="containrrr/watchtower:latest"

because the Image name is containerrr/watchtower and in the config.json containerrr is not set because it is from dockerhub.

Hi there! 👋🏼 As you're new to this repo, we'd like to suggest that you read our code of conduct as well as our contribution guidelines. Thanks a bunch for opening your first issue! 🙏

None of these are errors. The level=debug indicates that those are just debug messages, and should not be treated as errors. The last messages for example, just tells you that it cannot find any explicit credentials for watchtower, so it just goes ahead and pulls it using public authentication. It's not an error, but nice information to have if you were trying to debug why it didn't use the credentials you expected etc.
