How To Change external IP address of Management Host?

Problem

• How to change external IP address of Management Host?

Environment

• Platform9 Edge Cloud - All Versions

Procedure

• Add a second interface (10.128.143.200) to the Deployment Host.
• Modify the externalIP field in the /opt/pf9/airctl/conf/airctl-config.yaml configuration file with the new IP address of the management Plane.

/opt/pf9/airctl/conf/airctl-config.yaml

externalIp: 10.128.143.200

• Make sure that the default route is reachable through the interface which has the new external IP assigned.
• Run configure-localhost which will update the iptables rule with the new management IP address.

sudo /opt/pf9/airctl/airctl configure-localhost --config /opt/pf9/airctl/conf/airctl-config.yaml

• Restart the HAPROXY daemon on the airctl host:

Command

sudo pkill haproxy

• Run configure-hosts to update the hosts and re-establish connection with the management plane:

Command

/opt/pf9/airctl/airctl configure-hosts --config=/opt/pf9/airctl/conf/airctl-config.yaml

• Remove the rules corresponding to old IP address:

Example

$ sudo iptables -S -t nat

$ sudo iptables -t nat -D OUTPUT -d 10.128.145.101/32 -p tcp -m tcp --dport 443 -j DNAT --to-destination 10.128.145.101:8443

$ sudo iptables -t nat -D PREROUTING -d 10.128.145.101/32 -p tcp -m tcp --dport 443 -j DNAT --to-destination 10.128.145.101:8443
