• VRRP_PEER_GROUPS (no default, mandatory): nodes IPs used to setup VRRP (see below)
• CHK_PROTO (default: https): health check proto on Ingress Controller (no TLS check)
• CHK_PORT (default: 443): Ingress Controller's main port used for health check and listening IPs detection

VRRP peer groups

Delimiters:

• |: group delimiter
• : IPs/CIDR delimiter in VRRP groups
• ;: VIPs (CIDR) delimiter in VRRP group
• ,: default gateway to link to VIPs in VRRP group

Example:

VRRP_PEER_GROUPS=172.31.226.108 172.31.226.109 172.31.226.110|10.34.0.11 10.34.0.12 10.34.0.10;10.34.0.1/24 10.34.0.2/24,10.34.0.254|10.34.1.10 10.34.1.11 10.34.1.12;10.34.1.1/24 10.34.1.2/24,10.34.1.254

Will configure 1 VRRP group containing 3 VRRP instances (172.31.226.*, 10.34.0.* and 10.34.1.*), as long as nodes contain IPs declared in the group, each group with its VIPs and gateway (here 2 VIPs 10.34.1.1/24 and 10.34.1.2/24 and 1 gateway 10.34.1.254 in the instance 10.34.1.*)
