At Meroton, we’ve long provided managed Buildbarn environments to help development teams streamline their build processes. Now, we’re excited to take it a step further with the introduction of our latest offering: Buildbarn Fundamentals.

This new course is designed to empower your team with the knowledge and practical skills needed to manage and operate your own Buildbarn environment. Whether you're just getting started with remote build execution or looking to take control of your infrastructure, this hands-on course will provide you with the tools to succeed.

Unlock the Power of Buildbarn with Expert Guidance​

Buildbarn Fundamentals is more than just a training session; it’s an opportunity to set up a production-ready Buildbarn reference cluster in your own AWS environment. By participating in the course, your team will not only understand what makes Buildbarn tick but also walk away with a fully functional Remote Build Environment (RBE) cluster, which you can continue to use or adapt to your organization’s needs.

At Meroton, we believe that mastering the management of remote build environments is crucial for modern development workflows. This course is designed to be both comprehensive and practical, offering a deep dive into Buildbarn while equipping your team with the operational knowledge to effectively maintain and scale your infrastructure.

What You'll Learn​

Buildbarn Fundamentals is a hands-on course that teaches participants how to:

• Set up a fully operational Buildbarn cluster in AWS
• Manage and operate Buildbarn clusters independently
• Integrate third-party tools to enhance your build environment and understand the needs of consumers
• Optimize caching, remote execution, and troubleshooting with Buildbarn

By the end of the course, your team will have the skills and confidence to self-manage a Buildbarn environment, enabling you to scale and optimize your development processes independently.

Before heads out to summer adventures I'd like to invite everyone to a cool summer Buildbar. At the Buildbar we'll eat good food, talk about interesting technical problems, new developments with Bazel and Buildbarn.

And also have a few beers.

Feel welcome to come over on Wednesday 19 June 2024, from 16 to 20.

Directions​

You'll find us at our Linköping offices at Fridtunagatan 33. Currently there is some ongoing construction but follow the red lines and you'll be fine.

After BazelCon we've all gotten a bit giddy and you might feel excited how the information presented at BazelCon might impact your development workflow. For that purpose we're inviting everyone in the wider bazel community to an open BuildBar at the Meroton offices.

Come over and digest BazelCon with high level technical discussions of the talks, great company, a pleasant atmosphere and also beer.

Feel welcome to come over this Thursday the first of December from 16 to 20.

We've performed some updates to the free tier and our pricing model.

Shared Cache​

The free tier has been upgraded into an environment with a 1TB cache. This means that you can use the free tier without worrying about hitting any limits or setup process.

Do note that while the cached items will only be accessible with the correct api keys, the storage area can be reclaimed by anyone. I.e. as the cache becomes full your items might be dropped.

With the current churn we expect any items in the cache last at least a week. However, you should always treat items in the cache as something which might be dropped at any moment. The purpose and design of the cache is to maximize build performance, not to provide storage.

Shared executors​

New for the free environment is the introduction of remote execution, this was previously only available for paying customers.

If you're using bazel you can simply add the --remote_executor=<...> flag and your builds will be done remotely.

The free environment has access to 64 shared executors.

Starter tier​

If you need dedicated storage for evaluation purposes we also offer a starter tier. The starter tier is a streamlined environment with 100 GB of dedicated cache and access to the same 64 executors as the free tier.

This allows you to try out remote execution and caching without being disturbed by others. While the 100GB dedicated cache will only be used by you and therefore not be overwritten by anyone else's build, the cache is still a cache and the system will still drop the cache entries if it determines it is useful for maximizing performance.

Need more executors?​

At the moment the starter tier has a fixed amount of shared executors. If you need a scalable solution contact us for setting up a custom Buildbarn environment of any size.

When you have a remote build and cache cluster it can sometimes be hard to track down what exactly is using all of your building resources. To help with this we have started a tips and trix section in the documentation where we will share methods we use to debug and resolve slow builds.

The first section is about build non-determinism. Ideally your build actions should produce the same output when run with the same input, in practice this is sometimes not the case. If you are lucky a non-deterministic action won't be noticed since the inputs for the non-deterministic action is unchanged it won't be rebuilt.

If you're not so lucky the non-determinism stems from a bug in the implementation and you should definitely pay attention to them. But how do you know which if any actions are non-deterministic?

This is not trivial but we have added a server side feature which allows detection of non-determinism with virtually no effort on your part.

Once activated it reruns a configured fraction of your actions and automatically flags them if they produce different outputs. The scheduling is done outside of your bazel invocation so your build throughput will be unaffected at the cost of an increase in the number of resources consumed. We suggest 1% which will only increase your resource use by a trivial amount but you could of course set it to 100% which would double the cost of your builds.

The purpose of these articles is to have a freeform area discussing ideas, technical issues, solutions and news in an indepth relaxed manner. It is not to serve as reference material, structured reference material should be available in the documentation section.

The article format allows more in depth on discussions for reacurring subjects. In contrast to the documentation published articles aren't changed, if the subject requires a revisit in the future then we publish a new post and add references to the old.
