katy-at-home

stuff on my k3s machine running at home

install k3s, helm3

1. install kubectl, alias k
2. install krew
3. k krew install ns
4. k krew install ctx
5. go
6. powerline go
7. k3s

• export INSTALL_K3S_EXEC=" --no-deploy servicelb --no-deploy traefik"
• export K3S_KUBECONFIG_MODE="664"
• curl -sfL https://get.k3s.io | sh -
• disable k3s servicelb (using metallb)
  • add --disable servicelb to /etc/systemd/system/k3s.service in section ExecStart
• add local storage (e.g. hard drives)
  • add --default-local-storage-path /data/usb1 because k3s manages the cm local-path-config -n kube-system. dont edit cm by hand unless you deploy local-path-provisioner by self
