I introduced local package with go modules
for server side api. It works fine in local environment without error by commanding go run main.go
.
But it does not work when commanding docker-compose up
.
I want to know how to fix Dockerfile
and docker-compose.yml
.
I command go mod init
at article
directory.
As result, it sets module github.com/jpskgc/article
in go.mod.

"github.com/jpskgc/article/api/controller"
)
api := router.Group("/api")
{
api.GET("/articles", func(c *gin.Context) {
controller.GetArticleController(c, db)
})
}
router.Run(":2345")
}

I expect server side api working fine without error in docker environment. But the actual is that docker environment for server side fails to run.
Here is error message when commanding docker-compose up
api_1 | main.go:14:2: cannot find package "github.com/jpskgc/article/api/controller" in any of:
api_1 | /usr/local/go/src/github.com/jpskgc/article/api/controller (from $GOROOT)
api_1 | /go/src/github.com/jpskgc/article/api/controller (from $GOPATH)
Here is the entire source code on github (branch: try-golang-mod).
