Merge in patch as option

[gfrid]

Lets assume the bellow scenario:

the patch replaces existing resources, it there any 'merge' ? 'op': 'merge' ?

    annotations = [
        {
            'op': 'add',  # You can try different operations like 'replace', 'add' and 'remove'
            'path': '/metadata/annotations',
            'value': {
                'external-dns.alpha.kubernetes.io/internal-hostname': ingress_name,
                'external-dns.alpha.kubernetes.io/target': ip

            }
        }
    ]

    annotate_deployment(apps_v1_api, name, annotations)

• Can you please explain this, I am little confused of what to do?

• Do I need to update this in setup.py?

[gfrid]

the idea is to annotate ingress but using "strategic merge" option, the current state is that python overwrites existing annotations. 'op': 'add' removes the existing and creates a new. This is important feature that needs to work as it allows Kubernetes external DNS: https://github.com/kubernetes-sigs/external-dns/blob/master/docs/faq.md to work in specific scenarios, from what i know there is no other way to do this. Rancher does it programmatically. Current workaround is to use kubectl inside the python using os.system

• Thank you for responding!
• I will try to find an alternate solution other than the rancher
• if I will not get any other, I will use kubectl inside the python using os.system
