# Docker Golang Hot-Reload

This repo contains `Dockerfile` for image containing Go v1.9.2 and [Fresh](https://github.com/pilu/fresh) reloader. It is relased on [Docker Hub](https://hub.docker.com/r/derberg/docker-golang-hot-reload/)

## Usage

Below example assumes you run the image in your project's location

```

#my-project is your project's location

PROJECT=/go/src/{my-project}

#below container run does the following

#rm - makes sure that once you stop the container it is immediately removed

#v - mounts your current directory into a container under proper location needed for Go

#w - sets working directory inside container to the one you mounted in your project. This is necessary, Go magic

#p - exposes port 3000 from inside to 3000 outside

docker run --rm \

    -v $(PWD):$PROJECT \

    -w $PROJECT \

    -p 3000:3000 \

    derberg/docker-golang-hot-reload:1.0

```

## Vendor directory case

Fresh is awesome, but every tool has some limits. For Fresh it is `vendor` directory with your dependencies. You need to exclude it by putting below config file (`runner.conf`) in the root of your project:

```

root:              .

tmp_path:          ./tmp

build_name:        runner-build

build_log:         runner-build-errors.log

valid_ext:         .go 

no_rebuild_ext:    .tpl, .tmpl, .html

ignored:           vendor

build_delay:       600

colors:            1   

log_color_main:    cyan

log_color_build:   yellow

log_color_runner:  green

log_color_watcher: magenta

log_color_app:

```

## Image publishing

```

docker login

docker build -t docker-golang-hot-reload .

docker tag docker-golang-hot-reload derberg/docker-golang-hot-reload:1.0

docker push derberg/docker-golang-hot-reload:1.0

```
