local_release_dir has insufficient nuances, as it needs to handle several cases, - where to put downloaded artifacts - where to search for when installing artifacts - where to search for when using artifacts (passing them via lookup to kubectl stdin for instance) Furthermore, depending on how the user set up download delegation, the value we want can be on the host the tasks is executing, on the delegated hosts, etc. Define variables on top of local_release_dir for differents contexts, handling which host context to use depending on `download_delegate`. Mostly, this boils down to choosing the correct `host` for hostvars[host]['local_release_dir'].

# Where ansible should look for artefacts when installing binaries / pre-loading container image

|
|
# account `download_delegate`, and in particular the scenario where:
|
|
# - hostvars['some_host']['download_delegate'] == 'other_host' or 'localhost' -> both scenario will result in the artefact transiting by localhost
|
|
# - hostvars['localhost']['local_release_dir'] != hostvars['some_host']['local_release_dir']
|
|
# We explicitly check hostvars
