Updated guestbook based on suggestions in the pull request Port of current guestbook's README.md Fix guestbook pod and service names Add go boilerplate Use role label for redis pods Give service.containerPort a name based value This gives better env variable keys like REDIS_MASTER_SERVICE_REDIS_SERVER_ADDR, etc. Avoid unnecessarily long names for service (esp in env vars) Adding guestbook deploy/destroy scripts for k8s These are probably only useful for quick testing. Maybe remove them before merging the pull request. Part of avoiding long names for services Update Dockerfiles to git clone from Google's repo Use correct service names while deleting them Fix the script usage path. K8s is not go gettable. Use git clone instead. Using my fork in the Dockerfile to release and update to the docker hub image. Doesn't delete all pods if you remove controller too soon Run the command in a shell to substitute env vars. Workaround for GoogleCloudPlatform/kubernetes#1309 GoogleCloudPlatform in lieu of my fork in Dckrfile Some directory structure changes for guestbook src README that explains the build process for source Strip down the html and css to absolute essentials Reformat JS according to Google's guidelines Also added code to set random colors for elements. Handle repetitive error checks using a common func Also uses @roberthbailey’s stripped down code for reading env vars infoString isn't really a string. Use info instead Remove deploy.sh/destroy.sh scripts Bind submit instead of keypress to capture submit Add links to /env and /info in the footer Reformat the JS Incorporating suggestions by @filbranden License boilerplate and some fixes to release.sh Update README.md Update README.md Add building on boot2docker info to README Accept docker bin path as a param for building Use kubernetes user to host the image on registry Don't get included in k8s's recursive build deps https://github.com/GoogleCloudPlatform/kubernetes/pull/1299#discussion_r 17638061

## Building and releasing Guestbook Image
Guestbook build process employs the usage of docker-in-docker to build an image within another. This requires that the build image has access to the `docker` program's binary, which defaults to the docker available on your host machine. In the case of boot2docker, `DOCKER_BIN` must be set to the binary's location in the boot2docker's vm.
Releasing the image requires that you have access to the docker registry user account which will host the image.
To build and release the guestbook image:
cd examples/guestbook-go/src
./script/release.sh
If you're using boot2docker, specify the `DOCKER_BIN` environment variable
DOCKER_BIN="$(boot2docker ssh which docker)" ./script/release.sh
#### Step by step
If you may want to, you can build and push the image step by step.
###### Start fresh before building
./script/clean.sh 2> /dev/null
###### Build
Builds a docker image that builds the app and packages it into a minimal docker image
./script/build.sh
If you're using boot2docker, specify the `DOCKER_BIN` environment variable
DOCKER_BIN="$(boot2docker ssh which docker)" ./script/build.sh
###### Push
Accepts an optional tag (defaults to "latest")
./script/push.sh [TAG]
###### Clean up
./script/clean.sh
