docker - Dockerfile build - possible to ignore error?

I've got a Dockerfile. When building the image, the build fails on this error:

automake: error: no 'Makefile.am' found for any configure output
Error build: The command [/bin/sh -c aclocal && autoconf && automake -a] returned a non-zero code: 1

which in reality is harmless. The library builds fine, but Docker stops the build once it receives this error. Is there any way I can instruct Docker to just ignore this?

See Question&Answers more detail:os

Sure. Docker is just responding to the error codes returned by the RUN shell scripts in the Dockerfile. If your Dockerfile has something like:

RUN make

You could replace that with:

RUN make; exit 0

This will always return a 0 (success) exit code. The disadvantage here is that your image will appear to build successfully even if there are actual errors in the build process.
