我正在嘗試將 docker 與 go lang 和 PostgreSQL 一起使用
我有這個專案的結構：
-project_name
- src
- app
- config
- main.go
- .env
- docker-compose.yml
- Dockerfile
docker-compose.yml 檔案包含（我需要 GO 服務器和 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" ]
當我運行 docker-compose up --build 我得到這個錯誤：
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
uj5u.com熱心網友回復：
將構建線更改為build: .線。compose 檔案和 Dockerfile 位于同一目錄中。
