I build a Dockerfile as:
FROM hexpm/elixir:1.15.7-erlang-26.1.2-alpine-3.17.5 AS releaser
RUN apk add --no-cache build-base git python3 curl
WORKDIR /app
RUN mix do local.hex --force, local.rebar --force
COPY config/ ./config/
COPY mix.exs mix.lock ./

WORKDIR /app
COPY --from=releaser /app/_build/prod/rel/liquid ./
CMD ["bin/liquid", "eval", "Release.migrate", "&&", "exec", "bin/liquid", "start"]
and this is my docker-compose.yml:
version: "3.8"
services:
pescarte:

context: .
container_name: liquid_dev
ports:

environment:

healthcheck:
test: [ "CMD-SHELL", "pg_isready -U liquid -d liquid" ]
interval: 5s

However when i try to run docker compose up I get this error:
liquid_dev | ** (UndefinedFunctionError) function Release.migrate/0 is undefined (module Release is not available)
liquid_dev | Release.migrate()
liquid_dev | nofile:1: (file)
liquid_dev | (stdlib 5.1.1) erl_eval.erl:750: :erl_eval.do_apply/7
liquid_dev | (elixir 1.15.7) lib/code.ex:543: Code.validated_eval_string/3
liquid_dev exited with code 1
The full repository with the source code (empty phoenix apps) can be found here
And trying to build with docker build -t liquid-pescarte —no-cache —progress plain . gives all correct instructions and it compiles down all my umbrella apps, so I didn’t understand why on the runtime its brokes.
