toabi commented 3 years ago

This replaces PR https://github.com/StarpTech/k-andy/pull/12

Notable changes:

wireguard as flannel backend so cross-az traffic is protected. See https://docs.hetzner.com/cloud/networks/faq/#is-traffic-inside-hetzner-cloud-networks-encrypted
Allow usage of existing hcloud networks
Nodes get agent-group name as label so nodeSelectors can be used easily
Added multiple useful outputs
It's possible to add taints to node-groups
Minor version update of hcloud ccm and hcloud csi

[ ] Taints are unreliable, just recreated some clusters and not all nodes got the taint.

Hi @toabi what's the status?

toabi commented 2 years ago

Phew had a month of holidays :D the current workaround we used before is to always apply the taints because there is no good way to find out which ones are untainted.

toabi commented 2 years ago

The taint issue is fixed in #15 - now they are set when the node registers. When you change them, agents have to be recreated, but that shouldn't really be a problem.
