42 # as part of the deployment transitions to a healthy state. If no allocation
43 # transitions to the healthy state before the progress deadline, the

48 # The "canary" parameter specifies that changes to the job that would result
49 # in destructive updates should create the specified number of canaries

51 # canaries are healthy, they can be promoted which unblocks a rolling update
52 # of the remaining allocations at a rate of "max_parallel".

55 # blue/green deployments. When the job is updated, a full set of the new
56 # version is deployed and upon promotion the old version is stopped.
