Rocks Community meetups

Welcome to the Rocks Community! We’re excited to announce that we’ll be holding monthly virtual meetups to discuss various topics related to the community and the rocks initiative. The first meeting will be held on 20 April 1:30pm - 2:30pm UTC; and for this first rocking session we will be looking at going from Dockerfiles to Rockcraft recipes.

During these meetups, we’ll discuss:

  • ways to engage with the community,
  • what the rocks initiative has to offer,
  • Chisel package slices for crafting custom ultra-small Ubuntu-based images,
  • Rockcraft, our special declarative framework for building rocks.

The meetups will be held on an open Google Meet and will be a great opportunity for members of the community to connect, share ideas, and collaborate. We’ll also use this Discourse post to log meeting notes and the underlying Discourse topic to announce new meetings.

Join us on 20 April to learn how to craft ROCK-solid container images. Whether you’re a seasoned pro or just starting, we’ll help you become a true rockstar in the world of containerisation. We’ll be waiting for you backstage!


Thanks to everyone who joined our first Ubuntu Rocks Community Meetup. We had a great discussion about rocks’ approach to containers and how we aim to address open source challenges related to container images. We also introduced two new tools for building lean containers and aggregating software into best-in-class OCI images: Chisel and Rockcraft.

For those who missed the meetup, the recording is available at We encourage you to watch it and join our future meetups, which will be held monthly on an open Google Meet. Next one should happen late May, keep posted.

In our first meetup, we focused on going from Dockerfiles to Rockcraft recipes. We introduced Chisel package slices for crafting custom ultra-small Ubuntu-based images and showed how Rockcraft can be used as a declarative framework for building rocks. We offer these tools to help developers become Rockstars in the world of containerisation. :wink:

See you next time!


Hello Rockers,

Mark your calendars for our next rock’ing session. We’ll be taking the stage at the upcoming OpenSearch community session on Tuesday, July 11, 2023 at 04:00 PM UTC.

Fellow Rockstars will be showcasing the work done on ‘Charmed OpenSearch’ —building an Ubuntu ROCK for the OpenSearch software. Our Snapcraft friends will also be there to demonstrate Snaps’ alignment with Rocks: it has never been so easy to ship quality software across platforms!

Come and join us next Tuesday to see the power of rocks in action with the practical demonstration of OpenSearch OCI images.
