User story:

As a user, I want to add AWS tags when creating a new node pool on an existing HCP AWS cluster so that I can more easily mange my resources in AWS.

Additional information

In order to make the UI feel more stream-lined, the labels and AWS tags are combined into a single section.

Acceptance criteria:

• When adding a new label/tag the checkbox to make the entry an AWS tag will be unchecked (aka by default new items will be labels)
• When adding  AWS tags, the user must enter a key value and may enter a value (but is not required to do so).
• A machine pool may have up to 17 AWS tags. Once there are 17 AWS tags, the user will not be allowed to create another. - The checkbox to make an item an AWS tag will be disabled.
• If more than 17 AWS tags are added, an error will be shown when the user tries to create the machine pool.
• For a given machine pool, the AWS tag key must be unique
• The AWS tag key cannot begin with "aws"
• The AWS tag key must between 1 and 128 characters
• The AWS tag value must be between 0 and 256 characters
• Allowed characters for both AWS tag key and value are:
  • Letters
  • Numbers
  • Spaces
  • Any of these special characters: _ . : / = + - @
• The ability to add an AWS tag will only be available to HCP AWS clusters
• When editing a machine pool - the user will be able to view but not modify AWS tags.  In addition, the user will not be able to add new ones.

Mockups/Design (if available)

See mockup 2.b.4

Validation will appear as it does today but will follow the validation rules above if a user selects to make an item an AWS tag

See screenshot 2.a.1 for an example

Out of scope

This story is just for the ability to add an AWS tag - other items in the design doc including organizing the add/edit machine pool into subtags is covered by other stories.

Just to be clear - this only applies to adding a new machine pool.  The ability to add/edit AWS Tags on an existing machine pool is not yet available and will be covered in another epic once the API is ready.

Implementation notes

The ability to add/edit AWS tags for a node pool is available in the node pool API (GET, POST, PATCH), for example: GET /api/clusters_mgmt/v1/clusters/

/node_pools/

With the following structure:

aws_node_pool > tags
