Looping over map key:value pairs?

[IAMSolaara]

Hello,
I have seen that you can loop over a map variable using for, but it loops over the values, not keys or key:value pairs.

I have this task declared:

tasks:
  map_test:
    vars:
      NODES_MAP:
        map:
          foo: { type: a }
          bar: { type: a }
          baz: { type: b }
    cmd:
      for: { var: NODES_MAP }
      cmd: "echo map key: {{.ITEM}}"

And thus get as output:

$ task map_test
task: [map_test] echo map key: map[type:a]
map key: map[type:a]
task: [map_test] echo map key: map[type:a]
map key: map[type:a]
task: [map_test] echo map key: map[type:b]
map key: map[type:b]

which just gives me the values, but not the keys.

Is there a way to loop over a key:value pair, like a record? Am I missing something?

Thanks

I guess one way to do this would be turning the map into a list of maps, thus getting:

NODES:
  - map:
      key: foo
      type: a
  - map:
      key: bar
      type: a
  - map:
      key: baz
      type: b

@IAMSolaara When looping over maps, we make the {{.KEY}} variable available for use. You can see this in our looping over variables documentation. e.g.

tasks:
  map_test:
    vars:
      NODES_MAP:
        map:
          foo: { type: a }
          bar: { type: a }
          baz: { type: b }
    cmd:
      for: { var: NODES_MAP }
      cmd: "echo map key: {{.KEY}} - {{.ITEM}}"
