- `oc` is the OpenShift command-line client
                        - Some common commands:
                          - Login: `oc login`
                          - Projects: `oc projects`, `oc new-project`
                          - Information: `oc get` and `oc describe` (describe is for humans, get is machine-friendly JSON/YAML)
                          - Create: `oc create`
                          - Modify: `oc edit` and `oc replace` (edit is interactive)
                          - Delete: `oc delete`

- Create a new application from source code, e.g.:

```txt
                        oc new-app https://github.com/openshift/django-ex.git
                        ```

- This clones the repo, analyses it, builds an image with the code, and launches it
                        - Make it reachable from the internet:

```txt
                        oc expose svc/django-ex
                        ```
