exited due to signal 15 when check keepalived status about kubeadm-ha

[cookeem]

This tutorial the keepalived is running in an offline internal network, if you run it in cloud provider environment, you should use cloud provider ‘s load balancer instead of keepalived.

Vip is an static IP address all masters can reach and not conflict in the network, at this point you should ask your network maintain team which IP address you can used as vip

@cookeem my keepalived is running in an office networks without cloud provider environment. I requested VIP with static IP address on all masters, the ip is fix and unique in our office networks, I configured it, the 3 master status are working well, but the keepalive are not show correct status, below is the error info, it´s seems the password is invalid. is it related with "K8SHA_KEEPALIVED_AUTH"? do you know how get this key in my kubernetes cluster? thanks.

Can you show me all the keepalived.conf files? Make sure all this segment is the same:

    authentication {
        auth_type PASS
        auth_pass K8SHA_KA_AUTH
    }

[GangChenTFS]

below is the output, as same as setup in create-config.sh, thanks. authentication { auth_type PASS auth_pass 412f7dc3bfed32194d1600c483e10ad1d } $ cat create-config.sh # keepalived auth_pass config export K8SHA_KEEPALIVED_AUTH=412f7dc3bfed32194d1600c483e10ad1d

workaround is disable these line in keepalived.conf
