Create and edit instance tags

The instances created on a cloud provider can be assigned special metadata to help manage, bill or audit the resources. On Amazon Web Services (AWS), they are referred to as instance tags. You can create and edit these on the Universe dashboard of the Yugabyte Platform console.

1. Create instance tags

During the universe creation step, with an AWS cloud provider, use the Yugabyte Platform console to provide the option to input the instance tags as a map of keys and values as shown below.

User can provide these key-value pairs in any order.

Templated tags

Name is the only key that can have templated tags, so it can be made of different parts filled in at run-time to determine node and instance names.

• The parts of the template should be enclosed between ${ and }.
• The reserved keywords that can be specified: universe, instance-id, zone, and region.
• Templated tag value needs to have instance-id at the minimum.
• Order of the parts of template do not matter.

Check Cloud Provider instances*

Browse to the cloud provider's instances page. In this example, since you are using AWS as the cloud provider, browse to EC2 -> Running Instances in the correct availability zone and search for instances that have test-tags in their name. You should see something as follows in the Tags tab of those instances.

2. Edit instance tags

The map of instance tags can be changed using the edit universe operation. You can modify, insert, or delete existing instance tags as shown below:

These are changes, compared to the input during the create universe:

• Billing was modified.
• MyInfo was deleted.
• NewInfo was added.
• Department was not changed.

Note that the Name key field cannot be edited.

As before, you can confirm on the cloud provider list of instances that the tags have been updated correctly:
