# Try to follow "THING:ACTION:SPECIFIER" for specific actions.
# Examples:
# - chart:lint:redpanda # Lint the redpanda chart
# - helm:add-repo:jetstack # Add the jetstack repo to helm
# - helm:install:cert-manager # Install cert-manager using helm
# When this files becomes too long, all of THING can be extracted into it's own
# file.
# For CI or running many types of similar ACTIONs, have a top level task named
# just ACTION. For example, "lint" would run tasks that match *:lint:*. (Though
# there's no matching in taskile AFAIK so this is done by hand).
#
# Feel free to change this format provided there's a general flow to the new
# format, all existing tasks are changed, and backwards compatibility is
# maintained via aliases.
