how to set variables on the command line

Hi @quaint-belgium-6566 you can set variables like the example below:

# Override three specific variables value and run a task.
# Use dot notation to override nested variables
garden run my-run --var my-run-arg=foo,some-numeric-var=123,my-nested-vars.var1=bar

See https://docs.garden.io/using-garden/variables-and-templating#variable-files-varfiles for more details.
