41 # The "progress_deadline" parameter specifies the deadline in which an
42 # allocation must be marked as healthy. The deadline begins when the first
43 # allocation for the deployment is created and is reset whenever an allocation
44 # as part of the deployment transitions to a healthy state. If no allocation
45 # transitions to the healthy state before the progress deadline, the

50 # The "canary" parameter specifies that changes to the job that would result
51 # in destructive updates should create the specified number of canaries
52 # without stopping any previous allocations. Once the operator determines the
53 # canaries are healthy, they can be promoted which unblocks a rolling update
54 # of the remaining allocations at a rate of "max_parallel".
56 # Further, setting "canary" equal to the count of the task group allows
57 # blue/green deployments. When the job is updated, a full set of the new
58 # version is deployed and upon promotion the old version is stopped.
61 # Specifies if the job should auto-promote to the canary version when all
62 # canaries become healthy during a deployment. Defaults to false which means
63 # canaries must be manually updated with the nomad deployment promote

68 # last stable job on deployment failure. A job is marked as stable if all the
69 # allocations as part of its deployment were marked healthy.
