Out-of-cluster examples:

Not including required --telegramapi and --telegramgroup in examples for cleanliness.

Watch for pods and events in all namespaces:

kubewatch pods events | jq '.'

Same thing with docker:

docker run -it --rm \
-v ~/.kube/config:/root/.kube/config \
prg3/kubewatch pods events | jq '.'

Watch for services events in namespace foo:

kubewatch --namespace foo services | jq '.'

Same thing with docker:

docker run -it --rm \
-v ~/.kube/config:/root/.kube/config \
prg3/kubewatch --namespace foo services | jq '.'

In-cluster examples:

Run kubewatch in the monitoring namespace and watch for pods in all namespaces:

kubectl --namespace monitoring run kubewatch --image prg3/kubewatch -- pods

Run kubewatch in the monitoring namespace and watch for pods, deployments and events objects in all namespaces. Also flatten the json output:

kubectl --namespace monitoring \
run kubewatch --image prg3/kubewatch \
-- --flatten pods deployments events
