Setup
Ensure you have Nix installed. This is a requirement for the following steps.
Consult the developer docs for more info.
At the very least, nix should be in your PATH.
Build
You can build any image using Bazel. Start by querying the available images:
bazel query //image/system/...
You can either build a group of images (all images for a cloud provider, a stream, ...) or a single image by selecting a target.
bazel build //image/system:azure_azure-sev-snp_stable
The location of the destination folder can be queried like this:
bazel cquery --output=files //image/system:azure_azure-sev-snp_stable
Build and Upload
Similarly, you can also build and upload images to the respective CSP within a single step with the upload_* targets.
bazel run //image/system:upload_aws_aws-sev-snp_console -- --ref deps-image-fedora-40 --upload-measurements
The --ref should be the branch you're building images on. It should not contain slashes. Slashes should be replaced with dashes to
not break the filesystem structure of the image storages.
Optionally, the --upload-measurements option can be used to specify that measurements for the image should be uploaded, and --fake-sign specifies
that a debugging signing key should be used to sign the measurements, which is done for debug images.
Kernel
The Kernel is built from the srpm published under edgelesssys/constellation-kernel. We track the latest longterm release, use sources directly from kernel.org and build the Kernel using the steps specified in the srpm spec file.
After building a Kernel rpm, we upload it to our CDN and use it in our image builds.
Upgrading to a new Fedora release
- Search for the old Fedora releasever in the
image/directory and replace every occurence (outside of lockfiles) with the new releasever - Search for Fedora container images in Dockerfiles and upgrade the releasever
- Regenerate the package lockfile:
bazel run //image/mirror:update_packages - Build test images locally:
bazel query //image/system:all(pick an image name from the output)bazel build //image/system:IMAGE_NAME_HERE(replace with an actual image name)
- Let CI build new images and run e2e tests
- Upgrade kernel spec under edgelesssys/constellation-kernel to use new releasever
