A sample application in Go for Wercker.
This application uses the golang container obtained from the Docker Hub
Clone this repo and cd into the directory:
git clone https://github.com/happy-python/golang-wercker.git
cd golang-wercker
then build the executable:
go build
You can run the executable in a couple of different ways. The first is to simply launch the executable:
./golang-wercker
Now point your browser at http://localhost:5000 to see:
Hello World!
or at http://localhost:5000/cities.json to see:
{"cities":["Amsterdam","Berlin","New York","San Francisco","Tokyo"]}
The second, and more useful, way is to use the wercker dev command to launch the binary within a Docker container, using the base image defined in the box/id property at the top of the wercker.yml, like so:
wercker dev --expose-ports
The dev target inside wercker.yml uses the internal/watch step to dynamically reload the runtime container when sourcefile changes are detected, which allows you to quickly test changes without having to kill/rebuild/relaunch the container. For instance, add another city to the array on main.go:15 like so:
Cities: []string{"Amsterdam","Berlin","New York","San Francisco","Tokyo","London"},
and then refresh your browser pointing to http://localhost:5000/cities.json to see:
{"cities":["Amsterdam","Berlin","New York","San Francisco","Tokyo","London"]}}
