- `kube-ps1` makes it easy to track these, by showing them in our shell prompt
- It's a simple shell script available from https://github.com/jonmosco/kube-ps1
- It is installed on our training clusters, and when using [shpod](https://github.com/jpetazzo/shpod)
- On our clusters, `kube-ps1` is installed and included in `PS1`:
- It gives us a prompt looking like this one:
```
[123.45.67.89] `(kubernetes-admin@kubernetes:default)` docker@node1 ~
```
(The highlighted part is `context:namespace`, managed by `kube-ps1`)
- Highly recommended if you work across multiple contexts or namespaces!

## Installing `kube-ps1`
- It's a simple shell script available from https://github.com/jonmosco/kube-ps1
- It needs to be [installed in our profile/rc files](https://github.com/jonmosco/kube-ps1#installing)
(instructions differ depending on platform, shell, etc.)
- Once installed, it defines aliases called `kube_ps1`, `kubeon`, `kubeoff`
(to selectively enable/disable it when needed)
- Pro-tip: install it on your machine during the next break!
