docker-compose使用dockerfiles运行2个服务，main.go找不到任务“ phx.server”：没有这样的文件或目录

Question

使用4种服务运行docker-compose.yml文件时出现问题。它们是我的go微服务，phoenix Web服务器，mongodb和redis映像。

我在运行两个服务之前都在phoenix和golang dockerfiles中都指定了要更改工作目录的位置。在进行docker-compose时，当前出现以下错误。

找不到任务“ phx.server” main.go：没有这样的文件或目录

这是我的Dockerfile.go.development：

# base image elixer to start with
FROM golang:latest

# create app folder
RUN mkdir /goApp
COPY ./genesys-api /goApp
WORKDIR /goApp/cmd/genesys-server

# install dependencies
RUN go get gopkg.in/redis.v2
RUN go get github.com/gorilla/handlers
RUN go get github.com/dgrijalva/jwt-go
RUN go get github.com/gorilla/context
RUN go get github.com/gorilla/mux
RUN go get gopkg.in/mgo.v2/bson
RUN go get github.com/graphql-go/graphql

# run phoenix in *dev* mode on port 8080
CMD go run main.go

这是我的Dockerfile.phoenix.development：

# base image elixer to start with
FROM elixir:1.6

# install hex package manager
RUN mix local.hex --force
RUN mix local.rebar --force

# install the latest phoenix 
RUN mix archive.install https://github.com/phoenixframework/archives/raw/master/phx_new.ez --force

# create app folder
RUN mkdir /app
COPY ./my_app /app
WORKDIR /app

# install dependencies
RUN mix deps.get

# run phoenix in *dev* mode on port 4000
CMD mix phx.server

这是我的docker-compose.yml文件：

version: '3.6'
services:
  go:
    build:
      context: .
      dockerfile: Dockerfile.go.development
    ports:
      - 8080:8080
    volumes:
      - .:/goApp
    depends_on:
      - db
      - redis
  phoenix:
    # tell docker-compose which Dockerfile it needs to build
    build:
      context: .
      dockerfile: Dockerfile.phoenix.development
    # map the port of phoenix to the local dev port
    ports:
      - 4000:4000
    # mount the code folder inside the running container for easy development
    volumes:
      - .:/app
    # make sure we start mongodb when we start this service
    # links:
    #   - db
    depends_on:
      - db
      - redis
    environment:
      GOOGLE_CLIENT_ID: ${GOOGLE_CLIENT_ID}
      GOOGLE_CLIENT_SECRET: ${GOOGLE_CLIENT_SECRET}
      FACEBOOK_CLIENT_ID: ${FACEBOOK_CLIENT_ID}
      FACEBOOK_CLIENT_SECRET: ${FACEBOOK_CLIENT_SECRET}
  db:
    container_name: db
    image: mongo:latest
    volumes:
      - ./data/db:/data/db
    ports:
      - 27017:27017
  redis:
    container_name: redis
    image: redis:latest
    ports:
      - "6379:6379"
    volumes:
      - ./data/redis:/data/redis
    entrypoint: redis-server
    restart: always

对于与go微服务相关的错误，由于在PATH中找不到go二进制文件，因此您可能需要通过docker文件为go设置GOPATH env变量：

export GOPATH=
