What's up Docker ( aka WUD ) gets you notified when a new version of your Docker Container is available.

Errors about getaddrinfo and reading undefined for random containers at each run #380

Hi, Lately I notice that WUD frequently lists containers that are so-to-say not up-to-date, although they are already. I think it is related with the following errors I see from the WUD container:

Error: getaddrinfo EAI_AGAIN auth.docker.io
Error: getaddrinfo EAI_AGAIN registry-1.docker.io
Cannot read properties of undefined (reading 'tag') I get these errors for random containers at almost every check/run. I do a check/run every once a week, to not overload docker hub. Any idea what this is about? Br, T

I have the same issue, the container is unable to make outbound DNS/HTTP requests.

Ubuntu 22.04.4 LTS running Docker version 26.1.0, build 9714adc

I have 10+ containers on the same docker network and they can all access the Internet without issue, only this container (and wallabag) have this issue.

/etc/resolf.conf is the same for both a working container and the wud container

Not sure if something is hard coded during the build causing this?
