我正在努力在 Phoenix 1.6 中使用 Liveview 制作 Docker 映像并使用发布进行部署。

mix phx.server一切正常运行，但使用 Dockerfile 未加载资产。图像和 css/js 文件不加载。

资产文件夹与所有文件一起复制，并在文件夹中mix assets.deploy编译资产priv。

Docker 文件。我ESBuild用来编译资产。

ARG MIX_ENV="prod"

FROM hexpm/elixir:1.11.3-erlang-23.3.4.7-alpine-3.14.0 as build

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

# prepare build dir
WORKDIR /app

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

# set build ENV
ARG MIX_ENV
ENV MIX_ENV="${MIX_ENV}"

# install mix dependencies
COPY mix.exs mix.lock ./
RUN mix deps.get --only $MIX_ENV
RUN mkdir config

# copy compile-time config files before we compile dependencies
# to ensure any relevant config change will trigger the dependencies
# to be re-compiled.
COPY config/config.exs config/$MIX_ENV.exs config/
RUN mix deps.compile

COPY priv priv

# note: if your project uses a tool like https://purgecss.com/,
# which customizes asset compilation based on what it finds in
# your Elixir templates, you will need to move the asset compilation
# step down so that `lib` is available.
COPY assets assets
RUN mix assets.deploy

# compile and build the release
COPY lib lib
RUN mix compile

# changes to config/runtime.exs don't require recompiling the code
COPY config/runtime.exs config/

COPY rel rel
RUN PORT=4001 mix release

# prepare release image
FROM alpine:3.12.1 AS app
RUN apk add --no-cache libstdc++ openssl ncurses-libs

ARG MIX_ENV
ENV USER="elixir"

WORKDIR "/home/${USER}/app"
# Creates an unprivileged user to be used exclusively to run the Phoenix app
RUN \
  addgroup \
   -g 1000 \
   -S "${USER}" \
  && adduser \
   -s /bin/sh \
   -u 1000 \
   -G "${USER}" \
   -h "/home/${USER}" \
   -D "${USER}" \
  && su "${USER}"

# Everything from this line onwards will run in the context of the unprivileged user.
USER "${USER}"

COPY --from=build --chown="${USER}":"${USER}" /app/_build/"${MIX_ENV}"/rel/acompanhante ./

ENTRYPOINT ["bin/acompanhante"]

# Usage:
#  * build: sudo docker image build -t elixir/my_app .
#  * shell: sudo docker container run --rm -it --entrypoint "" -p 127.0.0.1:4000:4000 elixir/my_app sh
#  * run:   sudo docker container run --rm -it -p 127.0.0.1:4000:4000 --name my_app elixir/my_app
#  * exec:  sudo docker container exec -it my_app sh
#  * logs:  sudo docker container logs --follow --tail 100 my_app
CMD ["start"]
