This is the source code for the codefresh/cf-deploy-kubernetes container. This container is used to demonstrate a Kubernetes deployment using Codefresh.io

The deployment script makes the following assumptions about your application and Kubernetes configuration:

1. The application is deployed using the Kubernetes deployment API (versus the the replication controller directly). For more information read http://kubernetes.io/docs/user-guide/deployments/
2. The tested codebase has a yaml file (i.e. deployment.yml) that describes the Kubernetes deployment parameters and configuration of your application.
3. The script processes deployment.yml as a simple template where all {{ ENV_VARIABLE }} are replaced with a value of $ENV_VARIABLE deployment.yml
4. At the moment, only the basic username/pass authentication is supported.

The following env variables control the deployment configuration:

1. KUBERNETES_DEPLOYMENT_TIMEOUT - How much to wait for a successful deployment before failing the build. Defaults to 120 (secs).
2. KUBERNETES_USER - The user for the Kubernetes cluster. Mandatory.
3. KUBERNETES_PASSWORD - The password for the Kubernetes cluster. Mandatory.
4. KUBERNETES_SERVER - The server (HTTPS endpoint) of the Kubernetes cluster's API. Mandatory.
