Looks like it is missing dockerfile, how can i add dockerfile to existing image?
Not at all … The “Dockerfile” never makes it into the container. It’s more a recipe of “how to create the container”
What is your cmd to run the container ? (docker run …)
what does “docker logs < id of container >” give you ?
Puh … this seems more a problem of awsels/frontend-base rather than of docker …
From the error message I’d suspect that Ruby is not or only partial installed. But I don’t know “awsels” … so I can’t give you a decent suggestion.
You should contact the maintainer of the container to resolve this issue.
