# Continuous integration infrastructure

This page consolidates resources regarding our CI _infrastucture_, namely our [Buildkite agents fleet](#buildkite-agents).
This infrastructure is maintained by the [DevX team](../../../enablement/dev-experience/index.md).

## Buildkite agents

We maintain a shared fleet of Buildkite agents for continuous integration across all repositories.

### Buildkite agent queues

We have several different types of agents availables. We recommend explicitly declaring which type of agent you want your jobs to run on with the `agents: { queue: "standard" }` field in your pipeline configuration.

The currently available queues:

- `standard`: our default Buildkite agents, currently Docker-in-Docker agents running in Kubernetes
- `baremetal`: special Buildkite agents running on standalone machines
