The bookmarks are a handy reference, however the latest changes to the test do not allow for pre-existing bookmarks to be used.

## Updates since Sept 2021 Test Changes

### Helm

- understand Helm fundamentals

- install a release

- understand what a Helm release is

- update a Helm release

- list installed helm releases

- identify installed helm releases with problems

- identify chart values to customize

- install a Helm release specifying values using the --set flag

- uninstall a Helm release

### Docker

- create a simple Dockerfile using: FROM and COPY

- build an image with: docker build -t  .

- tag (and maybe push) image

- save image to a .tar file using: docker save

### Canary Deployment

- a service sends traffic to 2 deployments: 1) stable 2) canary.  Out

of the total number of desired pods, make sure the stable deployment

runs X pods, the canary deployment runs Y pods, and the service sends

traffic to both.

### Custom Resource Definitions (CRD)

- discover and use resources that extend Kubernetes

- know how to identify and use them.
