Setup

Ensure you have Nix installed. This is recommended in general but a requirement for the following steps. Consult the developer docs for more info. At the very least, nix should be in your PATH and either common --config=nix has to be set in the .bazelrc or you need to append --config=nix to each Bazel command.

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:openstack_qemu-vtpm_debug

The location of the destination folder can be queried like this:

bazel cquery --output=files //image/system:openstack_qemu-vtpm_debug

Upload to CSP

Warning! Never set --version to a value that is already used for a release image.

AWS

• Install aws cli (see here)
• Login to AWS (see here)
• Choose secure boot PKI public keys (one of pki_dev, pki_test, pki_prod)
  • pki_dev can be used for local image builds
  • pki_test is used by the CI for non-release images
  • pki_prod is used for release images

# Warning! Never set `--version` to a value that is already used for a release image.
# Instead, use a `ref` that corresponds to your branch name.
bazel run //image/upload -- image aws --verbose --raw-image path/to/constellation.raw --attestation-variant ""  --version ref/foo/stream/nightly/v2.7.0-pre-asdf

GCP

• Install gcloud and gsutil (see here)
• Login to GCP (see here)
• Choose secure boot PKI public keys (one of pki_dev, pki_test, pki_prod)
  • pki_dev can be used for local image builds
  • pki_test is used by the CI for non-release images
  • pki_prod is used for release images

export GCP_RAW_IMAGE_PATH=$(realpath path/to/constellation.raw)
export GCP_IMAGE_PATH=path/to/image.tar.gz
upload/pack.sh gcp ${GCP_RAW_IMAGE_PATH} ${GCP_IMAGE_PATH}
# Warning! Never set `--version` to a value that is already used for a release image.
# Instead, use a `ref` that corresponds to your branch name.
bazel run //image/upload -- image gcp --verbose --raw-image "${GCP_IMAGE_PATH}" --attestation-variant "sev-es"  --version ref/foo/stream/nightly/v2.7.0-pre-asdf

Azure

Note:

For testing purposes, it is a lot simpler to disable Secure Boot for the uploaded image! Disabling Secure Boot allows you to skip the VMGS creation steps above.

• Install az and azcopy (see here)
• Login to Azure (see here)
• Optional (if Secure Boot should be enabled) Prepare virtual machine guest state (VMGS) with customized NVRAM or use existing VMGS blob

export AZURE_RAW_IMAGE_PATH=path/to/constellation.raw
export AZURE_IMAGE_PATH=path/to/image.vhd
upload/pack.sh azure "${AZURE_RAW_IMAGE_PATH}" "${AZURE_IMAGE_PATH}"
# Warning! Never set `--version` to a value that is already used for a release image.
# Instead, use a `ref` that corresponds to your branch name.
bazel run //image/upload -- image azure --verbose --raw-image "${AZURE_IMAGE_PATH}" --attestation-variant "cvm"  --version ref/foo/stream/nightly/v2.7.0-pre-asdf

OpenStack

Note:

OpenStack is not one a global cloud provider, but rather a software that can be installed on-premises. This means we do not upload the image to a cloud provider, but to our CDN.

• Install aws cli (see here)
• Login to AWS (see here)

# Warning! Never set `--version` to a value that is already used for a release image.
# Instead, use a `ref` that corresponds to your branch name.
bazel run //image/upload -- image openstack --verbose --raw-image path/to/constellation.raw --attestation-variant "sev"  --version ref/foo/stream/nightly/v2.7.0-pre-asdf

QEMU

• Install aws cli (see here)
• Login to AWS (see here)

# Warning! Never set `--version` to a value that is already used for a release image.
# Instead, use a `ref` that corresponds to your branch name.
bazel run //image/upload -- image qemu --verbose --raw-image path/to/constellation.raw --attestation-variant "default"  --version ref/foo/stream/nightly/v2.7.0-pre-asdf

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.
