问题

我在Gin框架中构建了一个Go服务器，现在我想将其部署到GCP。我正在尝试在GCP Compute Engine的虚拟机上运行docker compose up -d命令。该命令在我的本地机器上成功运行，但在虚拟机终端中显示错误。
我在终端中收到的错误是：
service "app" depends on undefined service db: invalid compose project

我的docker-compose.yml代码如下：

  1. version: "3.7"
  3. services:
  4.   database:
  5.     container_name: mywealth-database
  6.     image: postgres:12.8
  7.     restart: always
  8.     environment:
  9.       - POSTGRES_USER=sharauq
  10.       - POSTGRES_PASSWORD=sharauq
  11.       - POSTGRES_DB=mywealth
  12.     ports:
  13.       - 5432:5432
  14.     volumes:
  15.       - db:/var/lib/postgresql/data
  16.   app:
  17.         container_name: app
  18.         restart: always
  19.         build: .
  20.         ports:
  21.             - "8080:8080"
  22.         depends_on: 
  23.             - db
  25. volumes:
  26.   db:

我的Dockerfile如下：

  1. # Start from the latest golang base image.
  2. FROM golang:latest
  4. # Add maintainer information
  5. LABEL maintainer="sharaukadr2001@gmail.com"
  7. # Set the current working directory inside an image.
  8. WORKDIR /app
  10. # Copy Go module dependency requirements file.
  11. COPY go.mod .
  13. # Copy Go Modules expected hashes file.
  14. COPY go.sum .
  16. # Download dependencies.
  17. RUN go mod download
  19. # Copy all sources.
  20. COPY . .
  22. # Build the application.
  23. RUN go build -o /mywealth
  25. # Delete source files.
  26. RUN find . -name "*.go" -type f -delete
  28. # Run the application.
  29. CMD ["/mywealth"]

I build a Go server in Gin framework and now I want to deploy it to GCP. I am trying to run docker compose up -d on VM in GCP Compute Engine. The command successfully runs in my local machine but shows error in VM terminal
The error I am getting in terminal is:
service "app" depends on undefined service db: invalid compose project

My docker-compose.yml code is:

  1. version: "3.7"
  3. services:
  4.   database:
  5.     container_name: mywealth-database
  6.     image: postgres:12.8
  7.     restart: always
  8.     environment:
  9.       - POSTGRES_USER=sharauq
  10.       - POSTGRES_PASSWORD=sharauq
  11.       - POSTGRES_DB=mywealth
  12.     ports:
  13.       - 5432:5432
  14.     volumes:
  15.       - db:/var/lib/postgresql/data
  16.   app:
  17.         container_name: app
  18.         restart: always
  19.         build: .
  20.         ports:
  21.             - "8080:8080"
  22.         depends_on: 
  23.             - db
  25. volumes:
  26.   db:

My Dockerfile is:

  1. # Start from the latest golang base image.
  2. FROM golang:latest
  4. # Add maintainer information
  5. LABEL maintainer="sharaukadr2001@gmail.com"
  7. # Set the current working directory inside an image.

  19. # Copy all sources.
  20. COPY . .
  22. # Build the application.
  23. RUN go build -o /mywealth
  25. # Delete source files.
  26. RUN find . -name "*.go" -type f -delete
  28. # Run the application.
  29. CMD ["/mywealth"]

你依赖其他服务，而不是卷。

你的数据库服务被称为 database，所以在 docker-compose.yml 文件中 app 服务定义的 depends_on 应该是 database，而不是 db。

英文:

You 'depend' on other services. Not on volumes.

Your database service is called database, so the 'depends_on' in the app service definition in the docker-compose.yml file should be database. Not db.
