How to replicate default kubernetes deployment services #424
Description
How to replicate default kubernetes deployment services with install options.
I installed k3s with 3 nodes using --cluster and --server options.
How is it possible to replicate these default services including coredns and metrics-server to run on each master nodes with install options?
Info:
curl -sLS https://get.k3sup.dev | sh
sudo install k3sup /usr/local/bin/
export USER=ubuntu
export SERVER_01=1.1.1.1
export SERVER_02=2.2.2.2
export SERVER_03=3.3.3.3
k3sup install --ip $SERVER_01 --user $USER --cluster --k3s-extra-args '--disable traefik --disable servicelb --disable local-storage --node-external-ip 1.1.1.1'
k3sup join --ip $SERVER_02 --user $USER --server-user $USER --server-ip $SERVER_01 --server --k3s-extra-args '--disable traefik --disable servicelb --disable local-storage --node-external-ip 2.2.2.2'
k3sup join --ip $SERVER_03 --user $USER --server-user $USER --server-ip $SERVER_01 --server --k3s-extra-args '--disable traefik --disable servicelb --disable local-storage --node-external-ip 3.3.3.3'info:
