Given a kubernetes cluster with many helm charts in different namespaces, how can I use helm to query the list of the last recently "touched" charts?
By "touched" I mean either installed (via helm install) or upgraded (via helm upgrade).
Something like: helm ls --all --sort-by updated.
I am also fine with a solution that uses kubectl directly.
The brute force way:
helm ls --max 99999 -A -o json | jq -r '.[] | "\(.updated)\t\(.name)"' | sort | tail | column -t
-A for all namespaces--max 99999 to "disable" paging (there's no better way as of 2024-09-24)jq to filter out on the "updated" fieldNote that a sample json entry looks like the following:
{
"name": "hoth-cb7f8a327",
"namespace": "default",
"revision": "2",
"updated": "2024-06-14 15:02:16.775174131 +0000 UTC",
"status": "deployed",
"chart": "hoth-0.1.0",
"app_version": "1.0.0"
}
Sample output of the aforementioned command:
2024-09-24 10:56:15.655674586 +0000 UTC geonosis
