 ## Pods evicted due to lack of disk space
 
 - Pods go to evicted state after doing X
-  - Related issues: [#133 - Pods evicted due to `NodeHasDiskPressure`](https://github.com/rancher/k3d/issues/133) (collection of #119 and #130)
-  - Background: somehow docker runs out of space for the k3d node containers, which triggers a hard eviction in the kubelet
-  - Possible [fix/workaround by @zer0def](https://github.com/rancher/k3d/issues/133#issuecomment-549065666):
-    - use a docker storage driver which cleans up properly (e.g. overlay2)
-    - clean up or expand docker root filesystem
-    - change the kubelet's eviction thresholds upon cluster creation: `k3d cluster create --k3s-agent-arg '--kubelet-arg=eviction-hard=imagefs.available<1%,nodefs.available<1%' --k3s-agent-arg '--kubelet-arg=eviction-minimum-reclaim=imagefs.available=1%,nodefs.available=1%'`

 - What's the solution: Hopefully, this will be solved by the planned [replacement of dqlite with embedded etcd in k3s](https://github.com/rancher/k3s/pull/1770)

-## Setting Kubernetes API Server flags (e.g. to enable feature flags)
+## Passing additional arguments/flags to k3s (and on to e.g. the kube-apiserver)
 
 - The Problem: Passing a feature flag to the Kubernetes API Server running inside k3s.
 - Example: you want to enable the EphemeralContainers feature flag in Kubernetes
 - Solution: `#!bash k3d cluster create --k3s-server-arg '--kube-apiserver-arg=feature-gates=EphemeralContainers=true'`
-  - Note: Be aware of where the flag require dashes (`--`) and where not.
+    - Note: Be aware of where the flags require dashes (`--`) and where not.
+        - the k3s flag (`--kube-apiserver-arg`) has the dashes
+        - the kube-apiserver flag `feature-gates` doesn't have them (k3s adds them internally)

+- Second example: `#!bash k3d cluster create k3d-one --k3s-server-arg --cluster-cidr="10.118.0.0/17" --k3s-server-arg --service-cidr="10.118.128.0/17" --k3s-server-arg --disable=servicelb --k3s-server-arg --disable=traefik --verbose`
+    - Note: There are many ways to use the `"` and `'` quotes, just be aware, that sometimes shells also try to interpret/interpolate parts of the commands
