executable not found on docker container

问题

我正在尝试在一个带有Go应用程序的Docker容器中运行CMD命令时遇到了一些问题。

这是我得到的输出：

  1. golang-api | /bin/sh: ./server: not found
  2. golang-api exited with code 127

这是Dockerfile：

  1. FROM golang:1.18-alpine
  3. RUN apk add g++ && apk add make
  5. WORKDIR /app
  7. COPY go.mod go.sum ./
  9. RUN go mod download
  11. COPY . .
  13. RUN make build
  15. EXPOSE 8000
  17. CMD ./server

这是负责构建命令的Makefile：

  1. LINUX_AMD64 = GOOS=linux GOARCH=amd64 CGO_ENABLED=1 GO111MODULE=on
  3. migrate:
  4.     cd cmd/migrations/$(FOLDER) && go run main.go
  6. build:
  7.     cd cmd && $(LINUX_AMD64) go build -a -v -tags musl -o server

这是docker-compose.yml：

  1. version: '3.1'
  3. services:
  4.   api:
  5.     build:
  6.       dockerfile: Dockerfile
  7.       context: .
  8.     container_name: golang-api
  9.     ports:
  10.       - "8000:8000"
  11.     restart: unless-stopped
  12.     depends_on:
  13.       - db
  14.     environment:
  15.       - POSTGRES_URL=$POSTGRES_URL
  17.   db:
  18.     image: postgres
  19.     restart: always
  20.     environment:
  21.       POSTGRES_USER: postgres
  22.       POSTGRES_PASSWORD: postgres
  23.     ports:
  24.       - '5432:5432'

完整输出：

英文:

I'm having some issue trying to run a CMD command inside a docker container with a Go application.

This is the output I've got:

  1. golang-api | /bin/sh: ./server: not found
  2. golang-api exited with code 127

This is the Dockerfile

  1. FROM golang:1.18-alpine
  3. RUN apk add g++ && apk add make
  5. WORKDIR /app
  7. COPY go.mod go.sum ./
  9. RUN go mod download
  11. COPY . .
  13. RUN make build
  15. EXPOSE 8000
  17. CMD ./server

And this is the Makefile responsible for the build command:

  1. LINUX_AMD64 = GOOS=linux GOARCH=amd64 CGO_ENABLED=1 GO111MODULE=on
  3. migrate:
  4. 	cd cmd/migrations/$(FOLDER) && go run main.go
  6. build:
  7. 	cd cmd && $(LINUX_AMD64) go build -a -v -tags musl -o server

And the docker-compose.yml

  1. version: '3.1'
  3. services:
  4.   api:
  5.     build:
  6.       dockerfile: Dockerfile

问题已解决。

不知何故，RUN cd cmd 命令似乎没有在预期的目录中生成文件。

尝试使用 RUN go build cmd/main.go 而不是使用 makefile，这也是评论中 @paltaa 指出的方法。

英文:

The problem was solved.

Somehow,the RUN cd cmd command seemed not generating the file in the expected directory.

Trying with RUN go build cmd/main.go instead of using the makefile worked, as well pointed by @paltaa in the comments.
