Deployments

This project produces docker images on each git tag. To run the image simply convert the git tag to the docker tag, for example to use version 0.0.3:

> docker run -it --rm -p 80 gugahoi/golang-healthcheck:0.0.3
2019/02/26 02:13:54 Listening on :80

or to test the endpoint with an ephemeral port:

> ID=$(docker run -it --rm -p 80 -d gugahoi/golang-healthcheck:0.0.3)
> curl -v $(docker port ${ID} 80)/healthcheck
*   Trying 0.0.0.0...
* TCP_NODELAY set
* Connected to 0.0.0.0 (127.0.0.1) port 32771 (#0)
> GET /healthcheck HTTP/1.1
> Host: 0.0.0.0:32771
> User-Agent: curl/7.54.0

{"version":"0.0.3","lastcommitsha":"b26b8ac3215b14dbf03cb1ad94d842fe9540e144","description":"Web API for ANZ"}

Note that the application listens on port 80 but if mapping it to different port in the host, access it via the host port.
