Re: Container UUID



Hmm that might work but we need to modify templates, not sure all of clients want this feature. Again this UUID should be unique to each pod.

 

Also some pods might  be created without using templates.

 

Is there any other way??

Hi.

 

You could use template parameters to generate a random value and use it into your contiainer template.

 

In you template.parameters:

 

  - description: My unique UUID

    name: UNIQUE_UUID

    generate: _expression_

    from: '[0-9A-F]{8}-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{12}'

 

And then in your DC:

 

spec:

    template:

        spec:

          containers:

          - env:

            - name: UNIQUE_UUID

              value: '${UNIQUE_UUID}'

 

 

Hope it helps.

Hi

 

Is there any way to put an environment variable which hold a unique UUID value per pod basis? If we put an environment variable at dc or rc level, same value propagating for all pods. That is expected behavior since all pods are creating using same template definition

 

If we add environment variable at pod level, its life time is limited.

 

Example:  Want to put an environment variable like below

 

UUID = FCAC382C-0CEB-40E4-9654-07715CDC9DD8

 

This UUID is unique to each pod.
