How to run golang using docker?

问题

我正在尝试使用Docker与Go语言和PostgreSQL。

我有以下项目结构：

  1. -project_name
  2.    - src
  3.      - app
  4.      - config
  5.      - main.go
  6.      - .env
  7.      - docker-compose.yml 
  8.      - Dockerfile

docker-compose.yml文件包含（我需要GO服务器和PostgreSQL）：

  1. version: '3.9'
  2. services:
  3.   app:
  4.     container_name: logger_app
  5.     build: ..
  6.     ports:
  7.       - "12000:12000"
  8.     restart: on-failure
  9.     volumes:
  10.       - .:/app
  11.     depends_on:
  12.       - postgres
  13.     networks:
  14.       - MYAPP
  16.   postgres:
  17.     image: postgres:latest
  18.     container_name: postgres_db
  19.     environment:
  20.       - POSTGRES_USER=${DB_USER}
  21.       - POSTGRES_PASSWORD=${DB_PASSWORD}
  22.       - POSTGRES_DB=${DB_NAME}
  23.       - DATABASE_HOST=${DB_HOST}
  24.     ports:
  25.       - '5432:5432'
  26.     networks:
  27.       - MYAPP
  29. networks:
  30.   MYAPP:
  31.     driver: bridge

Dockerfile包含：

  1. FROM golang:1.18 as builder
  3. RUN mkdir /app
  4. WORKDIR /app
  6. COPY . .
  8. RUN go get -d -v ./...
  10. RUN go install -v ./...
  12. RUN go build -o /build
  14. EXPOSE 12000
  16. CMD ["/build"]

当我运行docker-compose up --build时，我得到以下错误：

  1. failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount868285600/Dockerfile: no such file or directory
  2. ERROR: Service 'app' failed to build : Build failed

I'm trying to use docker with go lang & PostgreSQL

I have this structure for the project:

  1. -project_name
  2.    - src
  3.      - app
  4.      - config
  5.      - main.go
  6.      - .env
  7.      - docker-compose.yml 
  8.      - Dockerfile

the docker-compose.yml file contains ( I need GO server & PostgreSQL)

  1. version: '3.9'
  2. services:
  3.   app:
  4.     container_name: logger_app
  5.     build: ..
  6.     ports:
  7.       - "12000:12000"
  8.     restart: on-failure
  9.     volumes:
  10.       - .:/app
  11.     depends_on:
  12.       - postgres
  13.     networks:
  14.       - MYAPP
  16.   postgres:
  17.     image: postgres:latest
  18.     container_name: postgres_db
  19.     environment:
  20.       - POSTGRES_USER=${DB_USER}
  21.       - POSTGRES_PASSWORD=${DB_PASSWORD}
  22.       - POSTGRES_DB=${DB_NAME}
  23.       - DATABASE_HOST=${DB_HOST}
  24.     ports:
  25.       - '5432:5432'
  26.     networks:
  27.       - MYAPP
  29. networks:
  30.   MYAPP:
  31.     driver: bridge

The Dockerfile contains:

  1. FROM golang:1.18 as builder
  3. RUN mkdir /app
  4. WORKDIR /app
  6. COPY . .
  8. RUN go get -d -v ./...
  10. RUN go install -v ./...
  13. RUN go build -o /build
  15. EXPOSE 12000
  17. CMD [ "/build" ]

when I run docker-compose up --build I got this error:

  1. failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount868285600/Dockerfile: no such file or directory
  2. ERROR: Service 'app' failed to build : Build failed

答案1

得分: 2

将构建行更改为 build: . 行。Compose 文件和 Dockerfile 在同一个目录中。

英文:

Change the build line to build: . line. The compose file and Dockerfile are in the same directory.
