debug daemon (debugd)
Debugd is a tool we built to allow for shorter iteration cycles during development.
The debugd gets embedded into OS images at the place where the bootstrapper normally sits.
Therefore, when a debug image is started, the debugd starts executing instead of the bootstrapper.
The debugd will then wait for a request from the cdbg
tool to upload a bootstrapper binary.
Once the upload is finished debugd will start the bootstrapper.
Subsequently you can initialize your cluster with constellation apply
as usual.
Build cdbg
The cdbg
tool is part of the //:devbuild
target, if you follow the generic build instructions at build-develop-deploy.
If you need to build cdbg
standalone for your current platform, you can run
bazel build //debugd/cmd/cdbg:cdbg_host
debugd & cdbg usage
Follow the debug-cluster workflow to deploy a bootstrapper with cdbg
and debugd
.
Logcollection to Opensearch
You can enable the logcollection of debugd to send logs to Opensearch.
On Azure, ensure your user assigned identity has the Key Vault Secrets User
role assigned on the key vault opensearch-creds
.
On AWS, attach the SecretManagerE2E
policy to your control-plane and worker node role.
When deploying with cdbg, enable by setting the logcollect=true
and your name logcollect.admin=yourname
.
./cdbg deploy --info logcollect=true,logcollect.admin=yourname
# OR
./cdbg deploy --info logcollect=true --info logcollect.admin=yourname
Other available fields can be found in the filed list
For QEMU, the credentials for Opensearch must be parsed via the info flag as well:
./cdbg deploy \
--info logcollect=true \
--info logcollect.admin=yourname \
--info qemu.opensearch-pw='xxxxxxx'
Remember to use single quotes for the password.
You will also need to increase the memory size of QEMU to 4GB.
