ha-considerations.md: keepalived image missing curl

[jdefaver]

What happened?

I used the documentation in ha-considerations.md to deploy kubernetes with haproxy and keepalived on static pods. I determined keepalived was not working as expected by looking at /var/log/messages on the host (journal: /etc/keepalived/check_apiserver.sh exited with status 1).

By connecting to the keepalived pod, I realized curl was missing:

$ kubectl exec -it  -n kube-system keepalived-kubernetes-control-2 -- /bin/bash
$ cd /etc/keepalived/
$ ./check_apiserver.sh 
./check_apiserver.sh: line 11: curl: not found
*** Error GET https://localhost:443/

What you expected to happen?

Keepalived check script returning 0 when the endpoint is reachable.

How to reproduce it (as minimally and precisely as possible)?

Deploy as stated in the documentation.

is this by using osixia/keepalived:1.3.5-1?

i think we just need a newer image tag:
osixia/docker-keepalived#29

try osixia/keepalived:2.0.20

/kind documentation
/priority backlog
/help
