This kubectl plugin allows you to interact with Spring Boot Actuator endpoints in your Kubernetes cluster. Currently it provides two main functionalities: listing loggers and setting logger levels.
To install kubectl-actuator, you can download the latest release from
the GitHub releases page. Extract the downloaded archive
and move the kubectl-actuator binary to a directory in your PATH.
For shell completion to work, you need to have at least kubectl
version 1.26 installed. Also, kubectl_complete-actuator needs to be symlinked to kubectl-actuator. For example:
ln -sr ~/.local/bin/kubectl-actuator ~/.local/bin/kubectl_complete-actuatorThe plugin provides two subcommands: pod and deployment. You can use the pod subcommand to execute Actuator
commands for a specific pod, and the deployment subcommand to execute Actuator commands for a deployment.
