= Configuring periodic importing of image stream tags
|
|
|
|
[role="_abstract"]
|
|
To maintain up-to-date image definitions from an external container image registry, configure periodic importing of image stream tags. This process allows you to quickly re-import images for critical security updates by using the `--scheduled` flag.
|
|
|
|
.Procedure
|
|
|
|
. Schedule importing images:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc tag <repository/image> <image-name:tag> --scheduled
|
|
----
|
|
+
|
|
For example:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc tag docker.io/python:3.6.0 python:3.6 --scheduled
|
|
----
|
|
+
|
|
.Example output
|
|
[source,terminal]
|
|
----
|
|
Tag python:3.6 set to import docker.io/python:3.6.0 periodically.
|
|
----
|
|
+
|
|
This command causes {product-title} to periodically update this particular image stream tag. This period is a cluster-wide setting set to 15 minutes by default.
|
|
|
|
. Remove the periodic check, re-run above command but omit the `--scheduled` flag. This will reset its behavior to default.

[source,terminal]

|
|
$ oc tag <repositiory/image> <image-name:tag>
