Kubernetes launcher

Kubernetes Launcher is a simple config downloader and process supervisor. From high level it's similar to consul-template:

1. It can download configmaps to a specific location.

2. It can start an application a child process.

3. In case of configmap change, the new files will be redownloaded and the process will be restarted.

Configuration

• KUBERNETES_CONFIGMAP: configmap to download (data should contain the file->content mapping)
• KUBERNETES_CONFIGMAP_NAMESPACE: namespace of the configmap
• CONF_DIR: destination directory

Supervised process should be defined as an argument. Such as:

./kubernetes-launcher hdfs namenode
