It looks like a missing runtime dependency in your final image. Try changing
RUN apk add --no-cache openssl ncurses-libstoRUN apk add --no-cache openssl ncurses-libs libstdc++.tejpochiraju
Can confirm that this change seems to be needed ever since the
elixir:alpineimage used to build the app moved to Elixir1.12.LostKobrakai
The beam has native runtime dependencies and OTP 24 added libc as runtime dependency to support the JIT. With that change it seems like bare
alpine:3.9no longer brings all the required runtime dependencies. You’ll need to make sure that all of those those are present in the app container.romenigld
I asked in stackoverflow.
And put this:
and now worked for me. Thank you guys!
frankely
Thank you for sharing this!
romenigld
Hello @frankely I quit the postgresql-client because I installed in other way.
My final Dockerfile was this:
frankely
This is awesome! @romenigld, thank you for sending the newer version, I was looking for something like in order to deploy my api to Heroku and this did it! I’m currently using your initial Dockerfile, I’ll try this one instead.

Note this appears to be fixed in the upcoming docs of Phoenix 1.6.0.
With Alpine’ main selling point (if you will) being its small size, I’ve been wondering by how much the size of the runtime image would increase. Turns out: Not much.
libstdc++has 1.6MB and (its dependency)libgccnot more than 200KB.However, I wonder if it still makes sense to use Alpine if you need to add (gnu)libc anyways? (I haven’t yet compared the image size with the Debian based
-slimvariant.) And even if it still is considerably smaller (and or has other benefits), should it be more or less advertised as default approach in the docs, now that we have the-slimvariant?odix67
a good tip is to keep the the underlying os image versions in sync (build and release section), specifying a concrete version of the build image is also helpful, then look at Dockerfile of the build image and use the underlying os image version in your release image, then it would be unlikely to run into such issues
banano
my reason to use Alpine is not (mainly) size, but keep CVS reported security risks at minimum. Usually, ubuntu, even slim, as it packs more deps, it raises more security holes, which demands more maintenance.
btw, libgcc is not needed, just libstdc++
