Examples
Waits for all the model units to start with ubuntu.
juju wait-for model default --query='forEach(units, unit => startsWith(unit.name, "ubuntu"))'
Waits for all the model applications to be active.
juju wait-for model default --query='forEach(applications, app => app.status == "active")'

juju wait-for model default --query='life=="alive" && status=="available" && forEach(applications, app => app.status == "active")'
Details
The wait-for model command waits for the model to reach a goal state. The goal state can be defined programmatically using the query DSL (domain specific language). The default query for a model just waits for the model to be created and available.
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.
The model query DSL can be used to programmatically define the goal state for applications, machines and units within the scope of the model. This can be achieved by using lambda expressions to iterate over the applications, machines and units within the model. Multiple expressions can be combined to define a complex goal state.
