## Setup
|
|
|
|
Ensure you have Nix installed. This is a requirement for the following steps.
|
|
Consult the [developer docs](/dev-docs/workflows/build-develop-deploy.md) for more info.
|
|
At the very least, `nix` should be in your PATH.
|
|
|
|
Building the image also requires `newuidmap` and `newgidmap` to be present in the PATH. On Debian and Ubuntu, these can be sourced through
|
|
the `uidmap` package.
|
|
|
|
## Build
|
|
|
|
You can build any image using Bazel.
|
|
Start by querying the available images:
|
|
|
|
```sh
|
|
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.
|
|
|
|
```sh
|
|
bazel build //image/system:azure_azure-sev-snp_stable
|
|
```
|
|
|
|
The location of the destination folder can be queried like this:
|
|
|
|
```sh
|
|
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.
|
|
|
|
```sh
|
|
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](https://github.com/edgelesssys/constellation-kernel).
|
|
We track the latest longterm release, use sources directly from [kernel.org](https://www.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](https://github.com/edgelesssys/constellation-kernel) to use new releasever
