cAdvisor uses Kustomize to manage kubernetes yaml files. See the Kustomize readme for installation instructions, and for a description of how it works.
Pick a cAdvisor release
VERSION=v0.42.0
To update the image version(reference):
cd deploy/kubernetes/base && kustomize edit set image gcr.io/cadvisor/cadvisor:${VERSION} && cd ../../..
To generate the base daemonset:
kubectl kustomize deploy/kubernetes/base
To apply the base daemonset to your cluster:
kubectl kustomize deploy/kubernetes/base | kubectl apply -f -
To generate the daemonset with example patches applied:
kubectl kustomize deploy/kubernetes/overlays/examples
To apply the daemonset to your cluster with example patches applied:
kubectl kustomize deploy/kubernetes/overlays/examples | kubectl apply -f -
Example of modifications needed to deploy cAdvisor with perf support is provided in overlays/examples_perf directory (modification to daemonset and configmap with perf events configuration).
To generate and apply the daemonset with patches for cAdvisor with perf support:
kubectl kustomize deploy/kubernetes/overlays/examples_perf | kubectl apply -f -
On your own fork of cAdvisor, create your own overlay directoy with your patches. Copy patches from the example folder if you intend to use them, but don't modify the originals. Commit your changes in your local branch, and use git to manage them the same way you would any other piece of code.
To run the daemonset with your patches applied:
kubectl kustomize deploy/kubernetes/overlays/<my_custom_overlays> | kubectl apply -f -
To get changes made to the upstream cAdvisor daemonset, simply rebase your fork of cAdvisor on top of upstream. Since you didn't make changes to the originals, you won't have any conflicts.
