Docker构建Golang项目常见问题

1 Dockerfile
- 1.1 dockerfile报错：failed to read expected number of bytes: unexpected EOF
- 1.2 go mod tidy: go.mod file indicates go 1.21, but maximum supported version is 1.17
- 1.3 是否指定启动文件问题
2 构建及部署

1 Dockerfile

1.1 dockerfile报错：failed to read expected number of bytes: unexpected EOF

可能是docker拉取的镜像版本导致的问题的出现。

解决办法：

使用docker pull {镜像名称}，单独拉取构建时所需的基础镜像。
更改Dockerfile中的镜像版本。

1.2 go mod tidy: go.mod file indicates go 1.21, but maximum supported version is 1.17

在这里插入图片描述
因为Dockerfile中基础镜像是golang:alpine。查看golang:alpine可以看到里面的golang版本是1.17.5。

解决办法：更改Dockerfile中基础镜像为golang:1.21。

1.3 是否指定启动文件问题

2 构建及部署

构建

docker build -t ucenter-rpc:0.0.1 -f Dockerfile .

Docker创建网络

docker network create --driver=bridge zero_bridge_network

mkdir -p /opt/soft/go-zero/deploy/ucenter-rpc/etc
mkdir -p /opt/soft/go-zero/deploy/ucenter-rpc/logs

docker-compose
