Flip

An application to manage a Floating IP address on a Docker Swarm cluster.

The setup will consist of a Docker Swarm cluster with flip enabled on each managers. The flip daemon controls on which host the Floating IP will be configured. The Floating IP is only assigned to one host at a time (providing active / passive failover). In the event that the service fails on the active Docker host, Docker Swarm will relocate it on another member of the cluster and flip daemon will assign the Floating IP on that member.

Get started

To enable flip for a given service, add the label flip.enabled: "true" to the service configuration.

There is 2 types of datasource to get the Floating IP from.

File

Create a yaml file with the following content:

---
floating_ip:
  address: '192.168.12.226'
  netmask: '255.255.255.0'
  gateway: '192.168.12.1'

Then run the docker command:

docker run -d -v /var/run/docker.sock:/var/run/docker.sock -v /opt/flip/config.yml:/tmp/config.yml --net host --cap-add=NET_ADMIN --restart=always --name flip kassisol/flip:x.x.x -d file -o /tmp/config.yml -D

Metadata

Kassisol

The metadata server can be downloaded from https://github.com/kassisol/metadata. Once running and provisioned with data, run the docker command to start flip.

docker run -d -v /var/run/docker.sock:/var/run/docker.sock --net host --cap-add=NET_ADMIN --restart=always --name flip kassisol/flip:x.x.x -d kassisol -o "url=http://metadata.example.com:8080;itype=public;index=0" -D
