Tags are key:value pairs, acting as cloud resource metadata. For example, resources may be tagged with a tag key called Environment and the value being one of Development, Testing, QA, Production, etc. The value could also be left blank.

Organizations may require that specific tagging is mandatory and/or complies with various naming standards.

The Tag Compliance feature in CerteroX can be used to validate if a tag key exists.

  • Under Operate, select Tag Compliance.

  • Select Actions then Add.

  • Enter a name for your tag compliance policy. With Required Tag selected, enter the name of the required tag key. If necessary, you can filter the resources that the policy will apply to.

  • Select Add to save.

The new tag compliance policy will appear in the list. It will take a few minutes before the status column is updated with information.

You can see a list of resources that do not meet the policy (i.e. do not have the required tag key) by selecting the Show Resources button under Actions on the right-hand side.

The Resources page is shown with the policy filters.

The CerteroX Cluster feature can be used to validate the application of tags to resources. You will need to create a Cluster for the tag key.

  • Under Inform, select Resources.

  • On the right-hand side, select Actions then Configure Cluster Types.

  • Under Actions, select Add.

  • Give the Cluster Type a name and the tag key.

  • Click Create.

  • The new Cluster Type will appear in the list.

  • Back under Inform, select Resources.

  • Select Resource type and choose your Cluster type name.

The resources displayed will now be grouped by the different tag values of the tag key.

You can select a one of these tag values under Resource to see the combined details of the resources with that tag value.

You can then select Sub Resources to see the names of the resources with that tag value.

Cluster Types have a priority order, and resources can only belong to one Cluster at a time. To validate different tag keys, you need to create different Cluster types and to change the priority. i.e. the Cluster type with the highest priority will contain ALL the resources with the associated tag key.

It’s possible to have resource with a tag key but without the corresponding tag value. E.G. tag key = Environment but tag value is blank. In that scenario, CerteroX does not currently add the resource to the Cluster. i.e. you cannot find resources with missing tag values for a given tag key.
