10/27/2021, 9:34 AMHi all,
What is the best way to patch an existing deployment with pulumi?
for example, I want to 'translate' the following
kubectlcoredns Copy code
kubectl patch deployment coredns \
-n kube-system \
--type json \
-p='[{"op": "remove", "path": "/spec/template/metadata/annotations/eks.amazonaws.com~1compute-type"}]'b

you can't do this at the moment. you'd need to import the coredns pod into your state, and manage it from there

thanks for the answer.
As soon as I will import the coredns deployment into my code, how can I edit it and redeploy it?

once you've imported it into your state, you'd just update the code that has been imported too

I'm having some issues with the import.
As i'm executing the following python command:
Copy code
core_dns_deployment = k8s.apps.v1.Deployment(
resource_name=f'{cluster_name}-coredns-deployment',
args=k8s.apps.v1.DeploymentInitArgs(
metadata=k8s.meta.v1.ObjectMetaArgs(
namespace='kube-system',
name='coredns'
),
),
opts=ResourceOptions(import_='deployment/coredns', provider=k8s_provider, depends_on=[k8s_provider])
) Copy code

11/18/2021, 8:04 AMWe're trying to do exactly the same thing. Did you ever get this working @witty-belgium-75866? Are you aware of any code examples @billowy-army-68599?

11/18/2021, 8:29 AMhi @boundless-traffic-88044
my workaround was to patch
coredns Copy code
def patch_coredns(args):
kube_config = args[1]
# Only do the imperative patching during deployments, not previews.
if not pulumi.runtime.is_dry_run():
<http://pulumi.log.info|pulumi.log.info>('patching the coredns deployment ..')
patch = [{"op": "remove", "path": "/spec/template/metadata/annotations/eks.amazonaws.com~1compute-type"}]
with tempfile.NamedTemporaryFile('w') as temp_file:
temp_file.write(kube_config)
temp_file.flush()
args = [
'kubectl',
'patch', 'deployment', 'coredns', '-n', 'kube-system', '--type', 'json', '-p', json.dumps(patch)
]
new_env = os.environ.copy()
new_env['KUBECONFIG'] = temp_file.name
subprocess.run(args, env=new_env) Copy code
core_dns_patch = Output.all(fargate_profile.arn, kubeconfig).apply(patch_coredns)e

11/19/2021, 3:12 AMThanks for the workaround Amit - definitely seems less than optimal.
