我尝试在 Docker 环境中运行 Go API 服务器，但它运行失败并出现错误。

・client: react/axios 
・api: golang/gin 
・web-server: nginx 
・db: mysql 
・container: docker 
・ci-tool: travis 
・deploy: aws elastic beanstalk

  ├ client 
  ├ api 
  │  ├ main.go 
  │  ├ contoroller 
  │  │    └ contoroller.go 
  │  └ Dockerfile 
  ├ nginx 
  └ docker-compose.yml 

这是 api 的 Dockefile

//article/api/Dockefile 
 
FROM golang:latest 
WORKDIR '/app' 
RUN go get github.com/gin-contrib/cors 
RUN go get github.com/gin-gonic/gin 
RUN go get github.com/go-sql-driver/mysql 
RUN go get github.com/google/uuid 
RUN go get github.com/aws/aws-sdk-go/aws 
RUN go get github.com/aws/aws-sdk-go/service/s3 
RUN go get github.com/joho/godotenv 
COPY . . 
CMD ["go", "run", "main.go"] 

这里是docker-compose.yml

//docker-compose.yml 
  api: 
    build: 
      dockerfile: Dockerfile.dev 
      context: ./api 
    volumes: 
      - ./api:/app 
    depends_on: 
      - db 
    tty: true 
    environment: 
      - AWS_ACCESS_KEY_ID 
      - AWS_SECRET_ACCESS_KEY 
      - MYSQL_USER 
      - MYSQL_PASSWORD 
      - MYSQL_HOST 

我希望 docker-compose up 成功，但我失败了。

api_1     | main.go:14:2: cannot find package "github.com/jpskgc/article/api/controller" in any of: 
api_1     |     /usr/local/go/src/github.com/jpskgc/article/api/controller (from $GOROOT) 
api_1     |     /go/src/github.com/jpskgc/article/api/controller (from $GOPATH) 

请您参考如下方法:

为什么不使用 go 模块？

在 Golang 中使用多阶段构建 docker 非常流行。

这将创建一个非常小的图像。

FROM golang:1.12.9-alpine AS builder 
WORKDIR /src 
COPY ./go.mod ./go.sum ./ 
RUN go mod download 
COPY ./ ./ 
RUN CGO_ENABLED=0 go build \ 
-installsuffix 'static' \ 
-o /myapp . 
 
FROM scratch AS final 
COPY --from=builder /myapp /myapp 
 
EXPOSE 8080 
 
ENTRYPOINT ["/myapp"]  

请注意，您无法在正在运行的容器上运行 bash。 使用网络服务时需要添加ca-certificates
