Docker compose $GOPATH/go.mod 存在但不应该

Question

我有一个可以自行完美运行的 Dockerfile。

但是当我从docker-compose up --build运行它时

我得到： $GOPATH/go.mod exists but should not

下面是终端 output 的片段。

Successfully tagged app_app:latest
Starting golang_db ... done
Starting golang_app ... done
Attaching to golang_db, golang_app
golang_app | $GOPATH/go.mod exists but should not
.
.
golang_db | Version: '5.6.48'  socket: '/var/run/mysqld/mysqld.sock'  port: 3306  MySQL Community Server (GPL)
golang_app exited with code 1

有什么建议么？

Answer 1

在 GOPATH 的根目录中不需要任何包。 期望通常是有一个子目录 src/github.com/someproject/somerepo，这很可能是警告的根本原因

Answer 2

我整理了一下，上面的Dockerfile已经更新了。
