= 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>
----
