fleet - a Distributed init System.
fleet ties together systemd and etcd into a distributed init system. Think of it as an extension of systemd that operates at the cluster level instead of the machine level.
This project is very low level and is designed as a foundation for higher order orchestration. This is a preview release – please read the security notice.
fleet allows you to define flexible architectures for running your services:
- Deploy a single container anywhere on the cluster
- Deploy multiple copies of the same container
- Ensure that containers are deployed together on the same machine
- Forbid specific services from co-habitation
- Maintain N containers of a service, re-deploying on failure
- Deploy containers on machines matching specific metadata
List Machines in the Cluster
$ fleetctl list-machines MACHINE IP METADATA 148a18ff-6e95-4cd8-92da-c9de9bb90d5a 18.104.22.168 region=us-west 491586a6-508f-4583-a71d-bfc4d146e996 22.214.171.124 region=us-east
Submit & Start Units
$ ls examples/ hello.service ping.service pong.service $ fleetctl submit examples/* $ fleetctl start hello.service
$ fleetctl list-units UNIT LOAD ACTIVE SUB DESC MACHINE hello.service loaded active running - 148a18ff-6e95-4cd8-92da-c9de9bb90d5a ping.service - - - - - pong.service - - - - -
Before you can deploy units, fleet must be deployed and configured on each host in your cluster. After you have machines configured (
fleetctl list-machines), start some units.
fleet must be built with Go 1.2 on a Linux machine, or in a Go docker container. Simply run
./build and then copy the binaries out of bin/ onto each of your machines.
The current fleet interfaces should not be considered stable. Expect incompatible changes in subsequent releases.
See CONTRIBUTING for details on submitting patches and contacting developers via IRC and mailing lists.
