How to change the VIP in deployed cluster?

[vasilytray]

please tell me, if after installing the cluster I need to change the VIP, how do I do it on an already deployed cluster?

Hi @vasilytray !

1. Change IP adress in cluster_vip variable (vars/main.yml)
2. Run playbook with tag

for "Type B" (default) scheme

ansible-playbook config_pgcluster.yml --tags "vip_manager"

Or, for "Type A" scheme

ansible-playbook balancers.yml --tags "keepalived"

All tags https://github.com/vitabaks/postgresql_cluster/blob/master/tags.md

[vasilytray]

thank you very much! This is very cool! and to exchange data in keepalived, I just need to exchange data for downloading ansible-playbook deploy_pgcluster.yml --tags haproxy_conf,confd_conf,pgbouncer_config ?

[vitabaks]

Exactly, you are right
for the "Type A" scheme is a bit more complicated and requires more tags

or just run the entire playbook

ansible-playbook balancers.yml

pgbouncer_config

if you are using the latest version from the master branch then pgbouncer is already listening to all addresses

pgbouncer_listen_addr variable

thank you very much!
