but when I tried to do with this command:

docker run --env-file .env -p 8080:4000 romenigld/blog-prod

I`m getting this error:

It looks like a missing runtime dependency in your final image. Try changing RUN apk add --no-cache openssl ncurses-libs to RUN apk add --no-cache openssl ncurses-libs libstdc++.

Can confirm that this change seems to be needed ever since the elixir:alpine image used to build the app moved to Elixir 1.12.

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:3.9 no longer brings all the required runtime dependencies. You’ll need to make sure that all of those those are present in the app container.

I asked in stackoverflow.
And put this:


# prepare release image 
FROM alpine:3.14 AS app 
RUN apk upgrade --no-cache && \ 
apk add --no-cache postgresql-client bash openssl libgcc libstdc++ ncurses-libs

and now worked for me. Thank you guys!

Hello @frankely I quit the postgresql-client because I installed in other way.
My final Dockerfile was this:

FROM elixir:alpine AS build

# install build dependencies
RUN apk add --no-cache build-base npm git python3

# prepare build dir
WORKDIR /app

# install hex + rebar
RUN mix local.hex --force && \
    mix local.rebar --force

# set build ENV
ENV MIX_ENV=prod

# install mix dependencies
COPY mix.exs mix.lock ./
COPY config config
RUN mix do deps.get, deps.compile

# build assets
COPY assets/package.json assets/package-lock.json ./assets/
RUN npm --prefix ./assets ci --progress=false --no-audit --loglevel=error

COPY priv priv
COPY assets assets
RUN npm run --prefix ./assets deploy
RUN mix phx.digest

# compile and build release
COPY lib lib
RUN mix do compile, release

# prepare release image
FROM alpine AS app

# RUN apk add --no-cache openssl ncurses-libs
RUN apk upgrade --no-cache && \
    apk add --no-cache bash openssl libgcc libstdc++ ncurses-libs

WORKDIR /app

RUN chown nobody:nobody /app

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.

The beam has native runtime dependencies and OTP 24 added libc as runtime dependency to support the JIT.

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) libgcc not 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 -slim variant.) 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 -slim variant?

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

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++
