Collections

Each DataObject needs to be placed in a collection. See collection as a pod of multiple and similar objects. A collection may define a schema for its DataObjects but this is optional. At its simplest form a collection just has a name.

Create a new collection

kind: Collection
namespace: playground
name: accounts

tubectl create -f spec.yaml

Check the just created resource:

tubectl get co accounts -n playground -o yaml

The collection accounts is now ready to be used.

Define a collection with a schema

A schema enforces DataObjects to be consistent with the provided schema. An attribute in a defined schema may specify the value type, a label and regex.

Note Regex are of the type PCRE - Perl Compatible Regular Expressions.

kind: Collection
namespace: playground
name: accounts
data:
  schema:
    username:
      label: Username
      type: string
      require_regex: '#[a-zA-Z0-1]+#'
    firstname:
      label: Firstname
      type: string
    lastname:
      label: Surname
      type: string
    disabled:
      label: Surname
      type: int
    mail:
      label: Mail adress
      type: string
      require_regex: '#[a-zA-z0-9.-]+\@[a-zA-z0-9.-]+.[a-zA-Z]+#'

Note Changing a schema will have no affect on any existing DataObjects! DataObjects are only validated against the schema if they get added or modified.
