升级和 dockerizing Elixir/Phoenix 应用程序后 application_controller 中的内核 pid 终止错误

Question

我正在将一个 Elixir/Phoenix 应用程序从 1.7.4 升级到 1.11.4，并将其 docker 化。我已经设法更新依赖项并使用

iex -S mix phx.server

运行它。此外，我能够在本地生成一个版本并成功运行它，如下所示：

MIX_ENV=prod mix release jujuba

Compiling 2 files (.ex)
Compiling crate file_worker in release mode (native/file_worker)
    Finished release [optimized] target(s) in 0.85s
* assembling jujuba-24.61.1 on MIX_ENV=prod
* using config/runtime.exs to configure the release at runtime

Release created at _build/prod/rel/jujuba!

    # To start your system
    _build/prod/rel/jujuba/bin/jujuba start

Once the release is running:

    # To connect to it remotely
    _build/prod/rel/jujuba/bin/jujuba remote

    # To stop it gracefully (you may also send SIGINT/SIGTERM)
    _build/prod/rel/jujuba/bin/jujuba stop

To list all commands:

    _build/prod/rel/jujuba/bin/jujuba

当我用

_build/prod/rel/jujuba/bin/jujuba start

运行它时，它会正常启动。但是，当我构建它的图像并尝试运行它时失败了。

我正在使用这些命令构建和运行 docker：

docker build --progress=plain . -t jujuba:24.61.1
docker run -p 4000:4000 jujuba:24.61.1

它给出了这个错误：

docker run -p 4000:4000 jujuba:24.61.1

我的 Dockerfile 看起来像这样

FROM hexpm/elixir:1.11.4-erlang-24.3.4.8-alpine-3.17.0 as build

RUN apk add --update git build-base
RUN apk add curl

RUN mkdir jujuba
WORKDIR jujuba

ENV MIX_ENV prod

RUN curl https://sh.rustup.rs -sSf | sh -s -- --quiet -y
RUN source "$HOME/.cargo/env"
RUN mix do local.hex --force, local.rebar --force

RUN mkdir ./apps
RUN mkdir ./apps/jujuba

COPY mix.* ./
COPY ./mix.* ./apps/jujuba/
COPY ./mix.* ./apps/jujuba/
RUN mix deps.get --only $MIX_ENV
RUN mix deps.compile

COPY config ./config

RUN mix phx.digest

COPY rel ./rel
RUN PORT=4000 MIX_ENV=prod mix release jujuba

FROM alpine:3.17 AS app
# install runtime dependencies
RUN apk add --update openssl postgresql-client

# copy release to app container
COPY --from=build ./jujuba/_build/prod/rel/jujuba/ .

CMD ["sh", "/bin/jujuba", "start"]

你对我做错了什么有什么暗示吗？

这是我的主管的样子：

defmodule Jujuba.Application do
    use Application
  
    require Logger
  
    def start(_type, _args) do
      # Define workers and child supervisors to be supervised
      children = [
        # Telemetry
        JujubaWeb.Telemetry,
        # Start the endpoint when the application starts
        JujubaWeb.Endpoint,
  
        # Start the Ecto repository
        Jujuba.Repo.Master,
  
        # Start the flow builder supervisor
        {FlowBuilder.Supervisor, []},

        # Start AMQP Client
        {AMQPClient.Supervisor, []},
        # Start the generic contact import flow builder supervisor
        ContactImportFlowBuilder.Supervisor,

        # Start your own worker by calling: Jujuba.Worker.start_link(arg1, arg2, arg3)
  
        # Connection to Redis
        {Redix,
         name: :redix,
         host: Application.get_env(:redix, :host),
         port: Application.get_env(:redix, :port),
         password: Application.get_env(:redix, :password)},
  
        {Phoenix.PubSub, name: JujubaWeb.PubSub, adapter: Phoenix.PubSub.PG2}
      ]
  
      JujubaWeb.PlugPipelineInstrumenter.setup()
      JujubaWeb.MetricsExporter.setup()
      Jujuba.RepoInstrumenter.setup()
      JujubaWeb.PhoenixInstrumenter.setup()
  
      opts = [strategy: :one_for_one, name: Jujuba.Supervisor]
  
      Supervisor.start_link(children, opts)
    end
  end
