+# Themes & Things To Revise & Focus On
+- **ConfigMaps** & mounting into containers as volumes
+- More **ConfigMaps**, seriously it was on about three or four questions, practice all the ways of creating & using a ConfigMap [DOCS LINK](https://kubernetes.io/docs/tasks/configure-pod-container/configure-pod-configmap/)
+- Learn to use every variation of `kubectl run` and use with or without the `--dry-run -o yaml` flags, e.g.
+  - `--restart=Never` will create a **Pod**
+  - `--restart=Always` and `--replicas` will create a **Deployment**
+  - `--restart=OnFailure` will create a **Job**
+  - `--restart=OnFailure` and `--schedule` will create a **CronJob**
+  - Pass any commands for the pod/container to run at the end of the command after `--`  
+  e.g. `kubectl run webpod --image nginx --restart Never -- sleep 600`
+- Memorise the `volumeMount` and `volumes` syntax of pod & container spec, you don't have time to look it up, and it comes up a lot
+- Multi container pods, experiment with deploying this, and sharing a volume using `emptyDir`
+- Network Policy, `podSelectors` both for ingress/egress rules and applying the policy
+- PV and PVC, go through creating both and a pod to use the PVC, [DOCS LINK](https://kubernetes.io/docs/concepts/storage/persistent-volumes/)
+	- Surprise! one question required SSH onto a node to create a file for PV of `hostPath` type
+- Ingresses are not in the exam, nor are CRDs, Helm, etc, only core, non-beta API objects
+- Editing objects directly with `kubectl edit` ... only do this if you're confident of the change you're making, i.e. It's something mutable and you know the syntax
+  - If you save and it's wrong you're thrown back into the editor. If you're anything less than 99% sure, then export the YAML `kubectl get foobar -o yaml --export > blah.yaml` and edit that
+  - Often the change you are making requires you to delete the object (as it's an immutable field) so `kubectl edit` is never going to work
+
+
+# Bash/Terminal Tips
+
+Enable `kubectl` auto complete, very useful and part of the docs so you can copy & paste it   
+https://kubernetes.io/docs/reference/kubectl/cheatsheet/#kubectl-autocomplete
+
+
+Aliases. Shortening `kubectl` to `k` is a HUGE time saver! I used `kn` as a way to change namespaces
+```
+alias k=kubectl
+alias kn='kubectl config set-context --current --namespace '
+```
+
+Change editor used by `kubectl edit`
+```
+export KUBE_EDITOR=nano
+```
+
+If a command like delete is taking a while, hit `ctrl+z` to put it to the background and carry on working
