osixia/keepalived

Keepalived container image for VRRP high availability and VIP failover with dynamic configuration and hot reload.

Features

• Ready in one command: a virtual IP shared between your nodes, configured with a few environment variables.
• Three levels of configuration: environment variables, your own template, or your own keepalived.conf.
• Hot reload: Keepalived reloads when its configuration file changes, without restarting the container.
• State changes in the container logs: MASTER, BACKUP and FAULT transitions are logged, and you can plug in your own notify script.
• Up-to-date Keepalived: built from the upstream sources on Alpine, with JSON status support.
