Docker integration? about gin HOT 12 OPEN

I just released my Docker Container which runs gin. https://github.com/ntboes/docker-golang-gin https://registry.hub.docker.com/u/ntboes/golang-gin/

Usage:

docker run --name some-instance-name -v $(pwd):/go/src/app ntboes/golang-gin -p 4000

from gin.

Are you intending to use this in a production or a development environment.

gin wasn't originally intended to run in production, but you use case interests me 😄

from gin.

My idea was to have gin running in a container and have the code in a volume. Thus, when you git pull on the host machine you get the new code deployed automatically. The issue is that you lose control of dependencies, as you can't go get inside the container. Anyway, I think this might be an interesting model for CD, albeit slightly silly.

from gin.

You can use gin with Vagrant and the official golang image like this:

Vagrantfile

config.vm.define "app" do |v|
  v.vm.synced_folder ".", "/vagrant", disabled: true
  v.vm.synced_folder ".", "/go/src/app"
  v.vm.provider "docker" do |d|
    d.build_dir = "."
    d.ports = ["80:3000"]
  end
end

Dockerfile

FROM golang:onbuild
RUN go get github.com/codegangsta/gin
CMD ["gin"]
EXPOSE 3000

from gin.

While using the golang:1.4-wheezy and a simple martini example within a docker container, I get http: proxy error: dial tcp 127.0.0.1:3001: connection refused.

from gin.

Here's the dockerfile and example code I'm using:

https://gist.github.com/caiges/3527b9213ce841f511fe

and the command I'm using:

gin --path /opt/helloworld /opt/helloworld/main.go

from gin.

When I integrate Gin within Docker I receive this error message:

"/go/bin/gin: 1: /go/bin/gin: Syntax error: "(" unexpected"

Any ideas?

from gin.

Hmm, haven't observed that behavior. Can you link your code?

from gin.

It´s a concept test only:

[server.go]

package main

import "github.com/go-martini/martini"

func main() {
m := martini.Classic()
m.Get("/", func() string {
return "Hello world!"
})
m.Run()
}

[Dockerfile]

Hmm, might be something in the lifes.com repo you're using. I slightly modified your Dockerfile, built with docker built -t testapp and was able to run docker run testapp gin --path /usr/src/app /usr/src/app/main.go

from gin.

Yeah! Thanks caiges! now this part is working but now I received the following error message:

$ docker run -p 3000:3000 lifes-server gin --path src/lifes.com/ src/lifes.com/server.go
[gin] listening on port 3000
2015/01/27 18:33:52 http: proxy error: dial tcp 127.0.0.1:3001: connection refused

Any ideas?

Thank you so much!

@Raul-diffindo I had the same error when I was running without the CGO_ENABLED=0 flag
