UDS Core establishes a secure baseline for cloud-native systems and ships with compliance documentation and first-class support for airgap/egress-limited systems. Based on the work of Platform One, UDS Core expands on the security posture of Big Bang while providing advanced automation with the UDS Operator and UDS Policy Engine. UDS Core is a collection of several individual applications combined into a single Zarf package and we recommend using UDS CLI to deploy it as a UDS Bundle.

- K3D for dev & test environments or any CNCF Certified Kubernetes Cluster for production environments.
- UDS CLI v0.8.1 or later
While the UDS Bundles published by this repo can be used for dev and test environments and include a K3d cluster, UDS Core also publishes a UDS Package that is intended to be used in your own UDS Bundle. You can use the k3d-core-demo bundle as an example.
UDS Core publishes bundles you can use for trying out UDS Core or for UDS Package development where you only need part of UDS Core. These bundles leverage UDS K3d to create a local k3d cluster with tools installed to emulate a cloud environment.
Note
These UDS Bundles are intended for dev and test environments and should not be used for production. They also serve as examples to create custom bundles.
If you want to try out UDS Core, you can use the k3d-core-demo bundle to create a local k3d cluster with UDS Core installed by running the following command:
uds deploy k3d-core-demo:0.21.1In addition to the demo bundle, a k3d-slim-dev bundle also exists to work with UDS Core with only Istio, Keycloak & Pepr installed. Run the command below to use it.
Deploy Istio, Keycloak and Pepr:
uds deploy k3d-core-slim-dev:0.21.1UDS Core development leverages the uds zarf dev deploy command. For convenience, a UDS Task is provided to setup the environment. You'll need to have NodeJS 20 or later installed to continue. Here's an example of a flow developing the metrics-server package:
# Create the dev environment
uds run dev-setup
# If developing the Pepr module:
npx pepr dev
# If not developing the Pepr module (can be run multiple times):
npx pepr deploy
# Deploy the package (can be run multiple times)
uds run dev-deploy --set PKG=metrics-serverYou can perform a complete test of UDS Core by running the following command:
uds run test-uds-coreThis will create a local k3d cluster, install UDS Core, and run a series of tests against it, the same tests that are run in CI. If you want to run the tests against a specific package, you can use the PKG env variable. The following example runs the tests against the metrics-server package:
UDS_PKG=metrics-server uds run test-single-packageNote you can specify the --set FLAVOR=registry1 flag to test using Iron Bank images instead of the upstream images.
