Probably only want to stay with calico and flannel for now.

[MansM]

For flannel be careful with kube 1.7:
flannel-io/flannel#1243

@MansM is there a way to provide host-gw during k3s install? Like a flag or something?

[onedr0p]

Found it!

@MansM I'm guessing you needed to add this to your systemd service file on your k3s master so it persisted on reboot?

[onedr0p]

I updated our config here

Only needs to be on the master config and the clients share it?

[MansM]

On an existing cluster:
kubectl edit cm -n kube-system kube-flannel-cfg

@carpenike only master node

https://rancher.com/docs/k3s/latest/en/installation/install-options/

[onedr0p]

@MansM in order for the setting to persist thru a reboot you need to add this option to the systemd file on the master node.

I have to take your word for it, not using K3s myself. Running Kubeadm build cluster at home: https://github.com/MansM/vagrant-kubeadm

Though not in vagrant but on 2x Dell r710 with a pi3 as master

[onedr0p]

Oh, thought you were using k3s, ignore me :)
