This repository manages the continuous deployment of the [Pangeo](http://pangeo.io/) Cloud Federation
JupyterHub Kubernetes clusters using [hubploy](https://github.com/yuvipanda/hubploy).
It contains scripts to automatically redeploy when the image definition or
chart parameters are changed.

Changing the image will typically take ~20 minutes, and changing a Helm config variable ~1 minute.

## Setup a Kubernetes Cluster
#### Setup a Kubernetes Cluster

The first step to using this automation is to create a Kubernetes cluster and
install the server-side component Tiller on it (used for deploying applications
with the Helm tool). Scripts to do so using Google Cloud Platform can be found [here](https://github.com/pangeo-data/pangeo/tree/master/gce/setup-guide). For other cloud providers (e.g. AWS, Azure), follow the [Zero-to-JupyterHub](https://zero-to-jupyterhub.readthedocs.io/en/latest/create-k8s-cluster.html) guide.

## Install git-crypt
#### Install git-crypt

You will need to install
[`git-crypt`](https://www.agwa.name/projects/git-crypt/). `git-crypt` is used
to encrypt the secrets that are used for deploying your cluster. Please read this [HOW GIT-CRYPT WORKS](https://www.agwa.name/projects/git-crypt/) if new to it.

# Common Issues
### Troubleshooting

* `Error: could not find a ready tiller pod`
* Some times it takes a while to download the new tiller image, wait and try again.
* `Error: UPGRADE FAILED: "example.pangeo.io-staging" has no deployed releases`
* If your first deploy of an application fails. Run `helm delete dev-staging --purge` anywhere you have run `gcloud container clusters get-credentials`
