Waits for a machine to be created and started.

juju wait-for machine 0 --query='life=="alive" && status=="started"'


The wait-for machine command waits for a machine to reach a goal state. The goal state can be defined programmatically using the query DSL (domain specific language). The default query for a machine just waits for the machine to be created and started.

The wait-for command is an optimized alternative to the status command for determining programmatically if a goal state has been reached. The wait-for command streams delta changes from the underlying database, unlike the status command which performs a full query of the database.

Multiple expressions can be combined to define a complex goal state.
