6 oc rollback - Revert part of an application back to a previous deploy‐
7 ment
8
12 oc rollback [OPTIONS]
13
17 Revert an application back to a previous deployment
18 When you run this command your deployment configuration will be updated
21 to match a previous deployment. By default only the pod and container
22 configuration will be changed and scaling or trigger settings will be
23 left as- is. Note that environment variables and volumes are included
24 in rollbacks, so if you've recently updated security credentials in
25 your environment your previous deployment may not have the correct val‐
26 ues.
27 Any image triggers present in the rolled back configuration will be
30 disabled with a warning. This is to help prevent your rolled back
31 deployment from being replaced by a triggered deployment soon after
32 your rollback. To re-enable the triggers, use the 'deploy' command.
33 If you would like to review the outcome of the rollback, pass
36 '--dry-run' to print a human-readable representation of the updated
37 deployment configuration instead of executing the rollback. This is
38 useful if you're not quite sure what the outcome will be.
39
