This is a very simple web application that allows you to post messages and show them on an index page. This is the classic guestbook application, but way simpler and created so it could be showcased during trainings. In particular, this repository also holds Kubernetes manifests to train people with Kubernetes, and a Helm chart to do the same with Helm. This application uses redis as the backend storage.
This application has been written in go, so in order to build this application you need to perform:
$ go build
That being said, in order to run this application we recommend using Docker. You can build the Docker image like this:
$ docker build -t mssola/messages:0.1 .
I have already pushed some tags on the DockerHub. In order to run this application you need to take into account some environment variables:
MESSAGES_FILE_PATH: the base path were the index page is located. You usually don't have to set this one, because it only matters if you are planning to have the index page on another path (which is something that happens on the Docker image but that's already handled for you).MESSAGES_REDIS_HOST: the host were redis is located (default:localhost).MESSAGES_REDIS_PORT: the port were redis is bound (default:6379).MESSAGES_REDIS_PASSWORD: the password to be used when connecting to the redis instance.
You can find more information about how to deploy this application with plain Kubernetes manifests or with Helm in the kubernetes directory.
