Doc Text:
Cause: Improper error checking ignored errors from object creation during template instantiation. Consequence: Template instances would report successful instantiation when in some objects in the template had failed to be created. Fix: Errors on creation are properly checked now. Result: The template instance will report failure if any object within it cannot be created.

Description Ben Parees 2018-12-27 20:05:26 UTC 
+++ This bug was initially created as a clone of Bug #1661845 +++

While testing out use of ${{ }} in a template instance for use in api.ci, the template instance was listed as "successfully created" but one of the objects in the instance was not created.

The template instance should have caused a failure.

The bug in this case is the double replacement isn't being evaluated correctly causing the pod resources not to be valid Pod yaml.

--- Additional comment from Clayton Coleman on 2018-12-24 02:39:22 UTC ---

The injected replacement was not valid JSON.  So the pod creation failed, but the template instance didn't capture that.  Should have failed the template instance.

templateinstance will fail if detect the object name is invalid.

    message: 'Deployment.apps "${{TEST}}" is invalid: metadata.name: Invalid value:
      "${{TEST}}": a DNS-1123 subdomain must consist of lower case alphanumeric characters,
      ''-'' or ''.'', and must start and end with an alphanumeric character (e.g.
      ''example.com'', regex used for validation is ''[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*'')'
    reason: Failed
