[RFE] Juju should be able to tag nodes according to the applications they are running

[Pedro Guimarães]

Hi,

Juju does have a resource-tags config which allows to apply a tags to all nodes in a given model.

However, for backup purposes, I need to separate some nodes which run, e.g. ETCD vs k8s-master. Ideally, there should be another resource-tag option where juju can tag nodes with "application name" that is running on it + model name.

Option could be: resource-tag-application-names
And that will create, for example:
kubernetes.etcd
kubernetes.k8s-master
etc

Add a tagging option to allow setting custom VM tags at creation. This is different then tags for constraints: in this case you have a set of tagged nodes and you want to restrict the search.

$ juju add-machine --tags="key1=value1 key2=value2"

Or on a bundle:
machines:
  "0":
      constraints: ......
      tags: key1=value1 key2=value2...
