Queues are on the Move

Update July 22nd 2016 – Queue Routing has been moved to the UI, routing using solano.yml is no longer supported


A little over a year ago we released a feature called Custom Queues which exposed some of our internal routing logic to better select the compute resource that your build runs on. If you wish to use Docker containers you can route your builds to the “docker” queue to take advantage of Solano CI’s built-in Docker environment (read more). If you have a large test suite that needs to run using beefy machines with multiple GPUs, we’ll set up a queue for you to route your vector processing jobs through. 

Moving configuration items from the source-controlled solano.yml file isn’t a decision we take lightly. We’re big fans of moving away from the decade-old model of having your build’s configuration settings stored within the build system in a cryptic XML format. We are working on changes to the method we use to process configuration files very early in the session lifecycle. Configuration values that we absolutely must know before a worker starts now need to be set using the UI. We have some exciting enhancements coming soon that we’re super jazzed to share with you all, and moving to a UI-based queue routing configuration is the first step in enabling these enhancements.


For users who don’t currently use Custom Queues, this change won’t have any impact on your builds. For those of you that are using Custom Queues, we’ve pre-migrated the queue settings from your most recently run session to help you in the transition. All you need to do is verify that the auto-generated Queue Routers are correct, and click a button to enable the new routing scheme. We will be deprecating the config file approach to queue routing in July 2016 – we will be in contact with you prior to the cutoff to make sure everyone is migrated and ready for the change.

How to migrate

Step 1.

Visit your Solano CI Dashboard page, and click the gear icon for the repo you wish to configure. This will take you to the Repo Settings page.

Step 2.

Click “Queue Routing” in the left sidebar to bring up the Queue Routing settings page. Using the form at the bottom of the page, add branch/profile combinations and indicate which queue you want each combination to route to. You can use ‘*’ in the branch field to match all branches. If you’re not using profiles or don’t wish to change routing rules based on profile you can simply leave the field blank.Queue Routing settings page

Step 3.

Click “Save” to add the new route to your list of active Queue Routers. The routes are evaluated from top to bottom, the first rule that matches the branch & profile of the session that is being routed will be the one that determines the queue to use.

Step 4.

Once you validate that your Queue Routers are configured correctly, you can turn on Queue Routing for this branch by toggling the slider at the top of the page so that “Enabled” is highlighted in green. Congratulations, you’re fully migrated! Now would be a good time to remove any references to queue routing in your solano.yml to avoid any future confusion.

Like I mentioned earlier, we’ve automatically populated Queue Routers for repos that have queues defined in their solano.yml configuration file. All you should need to do is verify that the rules are correct, and click “Enable” to turn on the new Queue Routing. If you don’t see your queues auto-populated, please send us a link to a Session that has a queue defined in its solano.yml, and we’ll auto-generate the routers for you.

Stay tuned for some exciting news about upcoming changes that will have a big positive impact on your build performance.
