PiCluster 2.4 is out!

I am pleased to announce that a new version of PiCluster is out with some nice improvements. PiCluster aims to provide an easy-to-use solution to manage your Docker containers across multiple nodes. Let’s see what is new in this release.

New Features

Automatic Node Bootstrapping – Now you can increase node capacity easier than ever without having to manually add nodes to the cluster. Simply install the agent on a new node and copy your config.json  and start the agent daemon. When the agent starts, it will connect to the server and then the configuration will be added.

The container status in the Web Console now displays containers that are stopped or not running per what is in the config file. This new ability makes it very easy to see if there is a problem.

The CLI utility, Pictl, has finally been updated to work with the 2.x releases of PiCluster and comes with a new feature to show node metrics.

Enhancements

Now you can add your Elasticsearch and Kibana/Grafana details under the new ‘Configure Elasticsearch’ menu item without having to add it to the config file manually.

The Node and Container layout pages now refresh every 15 seconds. You can now use those pages as a useful dashboard.

Bug Fixes

The Kibana and Grafana dashboards were updated to support the latest releases and the Manage Container menu item now can display a large number of nodes properly.

A full list of changes is in the release notes. I encourage you to try out PiCluster to learn more and provide any feedback on our GitHub page.
