* Extend Tensorboard CRD with status.readyReplicas field
The Tensorboard CRD didn't contain any information about the
Tensorboard server being ready or not. So, the status of the
Tensorboard resource is extended so that it contains a
readyReplicas field, similar to the status.readyReplicas of
the deployment of the Tensorboard server.
* Extend Tensorboard controller to update status of Tensorboard CR
The frontend of the Tensorboard web-app will need information
about whether the Tensorboard servers are ready to connect or not.
As a result, the Tensorboard controller now copies the value of the
status.readyReplicas field of the Tensorboard deployment to the
status.readyReplicas of the Tensorboard CR.
Also, a Deployment() function was added for applying and updating
Tensorboard server deployments.
* Update tensorboard.status.phase of TWA backend response
The frontend of the TWA will need information about the status
of the Tensorboard server, so that it can inform the user about
the server being ready being ready to connect or not.
As a result, the backend sets the status.phase field of the response
to "ready", if tensorboard.status.readyReplicas == 1. Otherwise, the
status.phase field of the response is set to "unavailable".
Also, the getPVCName() function was added, which extracts the name
of a given PVC object.
* Add GET route for PVCs
The Tensorboard web-app frontend will be using an autocomplete
drop-bar to show user the PVCs that live in a specific namespace.
These PVCs could be used as log storages for the Tensorboard server.
So, a PVC GET route was added to the Tensorboard web-app backend.
* Add message to Tensorboard response object in TWA backend
The frontend of the TWA will need to output a response message for
every Tensorboard object. This response message will inform the
user about the current state of the Tensorboard server.
* Use status.STATUS_PHASE for backend response
* Add requirements.txt to TWA backend
* Use status.create_status() for backend response
