Increase open file limit

Add the following to this file: /etc/security/limits.conf

*       soft    nofile          1048576
*       hard    nofile          1048576
root    soft    nofile          1048576
root    hard    nofile          1048576

Add the following to this file: nano /etc/sysctl.conf

fs.inotify.max_user_instances = 1280
fs.inotify.max_user_watches = 10028400

Not sure if I need to modify the following:

Add DefaultLimitNOFILE=1048576 in /etc/systemd/system.conf and /etc/systemd/user.conf below [manager]

Setting up Kubernetes

Install the cluster

k0sctl apply
k0sctl kubeconfig > ~/.kube/config

Restore Sealed Secret key

(Restore sealed-secret.yaml from Backup)

k apply -f sealed-secret.yaml

Install ArgoCD

cd ops/argocd
k create ns ops
k kustomize --enable-helm | k apply -f -

From now on everything else will be installed / setup by ArgoCD
