12 oc set deployment-hook [OPTIONS]
13
17 Set or remove a deployment hook on a deployment config
18 Deployment configs allow hooks to execute at different points in the
21 lifecycle of the deployment, depending on the deployment strategy.
22 For deployments with a Recreate strategy, a Pre, Mid, and Post hook can
25 be specified. The Pre hook will execute before the deployment starts.
26 The Mid hook will execute once the previous deployment has been scaled
27 down to 0, but before the new one ramps up. The Post hook will execute
28 once the deployment has completed.
29 For deployments with a Rolling strategy, a Pre and Post hook can be
32 specified. The Pre hook will execute before the deployment starts and
33 the Post hook will execute once the deployment has completed.
34 For each hook, a new pod will be started using one of the containers in
37 the deployment's pod template with a specific command to execute. Addi‐
38 tional environment variables may be specified for the hook, as well as
39 which volumes from the pod template will be mounted on the hook pod.
40 Each hook can have its own cancellation policy. One of: abort, retry,
43 or ignore. Not all cancellation policies can be set on all hooks. For
44 example, a Post hook on a rolling strategy does not support the abort
45 policy, because at that point the deployment has already happened.
