airlock's Introduction

Airlock

Build status Container image

Airlock is a minimal update/reboot manager for clusters of Linux nodes. It is meant to be simple to run in a container.

Fleet-wide updates and reboots are coordinated via semaphore locking, with configurable groups and simultaneous reboot slots.

Configuration is done through a single TOML file. The service is stateless, and etcd3 is used to store the semaphore and to guarantee its consistency.

Quickstart

go get -u -v github.com/coreos/airlock && airlock serve --help

A TOML configuration sample (with comments) is available under examples.

An automatically built x86_64 container image is available on quay.io and can be run as:

docker run -p 3333:3333/tcp -v "$PWD/dist/examples/config.toml:/etc/airlock/config.toml" quay.io/coreos/airlock:master airlock serve -vv
