Docker of mix release crashes with "Exec format error"

QUESTION

Docker of mix release crashes with "Exec format error"

Asked 2020-Nov-03 at 15:25

Background

I have an executable created via mix release which works just fine when I run it with start on my local machine. However, my docker image crashes when trying to start the executable and I don't know why.

Docker ...

ANSWER

Answered 2020-Nov-03 at 15:25

RCA

This was a tricky one. After reading other similar questions (and the comments from @potibas and @Stefano) I found out what was happening.

So, as I have said, the release file works well on my local machine. This happens because in my local machine the files were being compiled to its operative system (OS).

Now, the docker VM does not have the same OS as my local machine. This matters because of this line:

COPY . /

Here I am copying everything from the workdir to docker. Including the binaries and dependencies compiled for my local machine's OS.

This caused the issue above mentioned.

Solution

There are 2 possible solutions.

Remove the _build and deps folders from the image after the COPY command, via RUN rm -r _build and RUN rm -r deps/.
Add the mentioned folders as well as all the non-essential files to a .dockerignore file.

I personally opted for the second option, as it allows me to have a leaner image.
