# 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 init` as usual.
|
|
|
|
## Build cdbg
|
|
|
|
```shell
|
|
mkdir -p build
|
|
cmake ..
|
|
make cdbg
|
|
```
|
|
|
|
## debugd & cdbg usage
|
|
Before continuing, remeber to [set up](https://docs.edgeless.systems/constellation/getting-started/install#set-up-cloud-credentials) your cloud credentials for the CLI to work.
|
|
|
|
With `cdbg` and `yq` installed in your path:
|
|
|
|
1. Run `constellation config generate` to create a new default configuration
|
|
|
|
2. Locate the latest debugd images by running `hack/find-image/find-image.sh`
|
|
|
|
3. Modify the `constellation-conf.yaml` to use an image with the debugd already included and add required firewall rules:
|
|
|
|
```shell-session
|
|
# Set full reference of cloud provider image name
|
|
export IMAGE_URI=
|
|
```
|
|
|
|
```shell-session
|
|
yq -i \
|
|
"(.provider | select(. | has(\"azure\")).azure.image) = \"${IMAGE_URI}\"" \
|
|
constellation-conf.yaml
|
|
yq -i \
|
|
"(.provider | select(. | has(\"gcp\")).gcp.image) = \"${IMAGE_URI}\"" \
|
|
constellation-conf.yaml
|
|
|
|
yq -i \
|
|
"(.debugCluster) = true" \
|
|
constellation-conf.yaml
|
|
```
|
|
|
|
4. Run `constellation create […]`
|
|
|
|
5. Run `./cdbg deploy`
|
|
|
|
By default, `cdbg` searches for the bootstrapper in the current path (`./bootstrapper`). You can define a custom path by appending the argument `--bootstrapper <path to bootstrapper>` to `cdbg deploy`.
|
|
|
|
6. Run `constellation init […]` as usual
|
|
