Garbage collection
Tanka can automatically delete resources from your cluster once you remove them from Jsonnet.
Note: This feature is experimental. Please report problems at https://github.com/grafana/tanka/issues.
To accomplish this, it appends the tanka.dev/environment: <hash>
label to each created
resource. This is used to identify those which are missing from the local state in the
future.
Note: The label value changed from the <name>
to a <hash>
in v0.15.0.
Because the label causes a diff
for every single object in your cluster and
not everybody wants this, it needs to be explicitly enabled. To do so, add the
following field to your spec.json
:
{
"spec": {
+ "injectLabels": true,
}
}
Once added, run a tk apply
, make sure the label is actually added and confirm
by typing yes
.
From now on, you can use tk prune
to remove old resources from your cluster.
