Before you can collect a support bundle, you need to have a client-only component available. Nothing needs to be installed in the cluster. The Troubleshoot client utility is packaged as a kubectl plugin, and can be installed using krew.
The support bundle plugin can be installed using a simple script:
curl https://krew.sh/support-bundle | bash
For additional options to install krew, visit https://github.com/kubernetes-sigs/krew/#installation.
Once you have the support bundle plugin installed on your workstation, you can generate a local support-bundle by giving the plugin a path to a set of collectors:
kubectl support-bundle <uri/path to collectors>
For example, to use a set of sample collectors:
kubectl support-bundle https://troubleshoot.replicated.com
This will connect to the cluster defined in your local context, and collect some basic information about the cluster. After it’s finished, it will write a file named “support-bundle.tar.gz” to the current working directory.
