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：
-project_name
- src
- app
- config
- main.go
- .env
- docker-compose.yml
- Dockerfile
docker-compose.yml文件包含（我需要GO服务器和PostgreSQL）：
version: '3.9'
services:
app:
container_name: logger_app
build: ..
ports:
- "12000:12000"
restart: on-failure
volumes:
- .:/app
depends_on:
- postgres
networks:
- MYAPP
postgres:
image: postgres:latest
container_name: postgres_db
environment:
- POSTGRES_USER=${DB_USER}
- POSTGRES_PASSWORD=${DB_PASSWORD}
- POSTGRES_DB=${DB_NAME}
- DATABASE_HOST=${DB_HOST}
ports:
- '5432:5432'
networks:
- MYAPP
networks:
MYAPP:
driver: bridge
Dockerfile包含：
FROM golang:1.18 as builder
RUN mkdir /app
WORKDIR /app
COPY . .
RUN go get -d -v ./...
RUN go install -v ./...
RUN go build -o /build
EXPOSE 12000
CMD ["/build"]
当我运行docker-compose up --build时，我得到以下错误：
failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount868285600/Dockerfile: no such file or directory
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.
