This endpoint checks whether a namespace is available in Bluemix and can be used to set up the private Docker images registry for an organization. When a HTTP code 201 Ok is returned, the namespace is already assigned to another organization in Bluemix and cannot be used. When a HTTP code 404 Not found is returned, the namespace can be used for your organization.
Consider the following rules when choosing a namespace for your organization:
- Every organization can have one namespace at a time only
- The namespace must be unique in Bluemix.
- The namespace can be 4-30 characters long.
- The namespace must start with at least one letter or number.
- The namespace can only contain lowercase letters, numbers or underscores (_).
