SampleController is not the most easy code to deal with. They have example on how they cast objects to a known resource type. And they also have example on how they lookup the resource from a lister.

Unless you have specific needs, I would recommend to also consider using kubebuilder and follow the kubebuilder book that has intuitive explanations of making controllers.

Resource not found error performing SSA create using dynamic client

Asked 2021-Jan-01 at 17:21

I was following @ymmt2005 excellent dynamic client guide. All is good until the final step when I make the actual PATCH call, and I get a the server could not find the requested resource error. Just about everything seems right, except I'm unsure about the 'FieldManager' field in the PathOptions struct. I'm not sure what "the actor or entity that is making these changes" refers to. Does this need to match something in my code or system? Any other ideas?

ANSWER

Answered 2021-Jan-01 at 17:21

The answer is really trivial. The original code assumes that namespace is provided in the manifest. The deployment endpoint does not automatically set namespace to default if the provided namespace is "", and errors out because "" is not a valid namespace. Therefore, I added logic to set namespace to default if not provided and presto, the server side apply will create the resource if it doesn't exist and update if it does exist. Thanks again @ymmt2005 .

The easiest approach would be to turn your object into an array using Object.values() and Object.keys(). Check out this plunker for an example.

If you want access to the keys as well as the value you can include an index in your *ngFor.

I am using the kubernetes sample controller and I want to increase the log verbosity

How to scale a CRD Controller in Kubernetes

Asked 2019-Jul-17 at 22:54

I'm reading a lot of documentation about CRD Controller

I've implemented one with my business logic, and sometimes I got this race condition:

I create a Custom Object, let's call it Foo with name bar
My business logic applies, let's says that it creates a Deployment with a generated name, and I save the name (as reference) it in the Foo object
I remove the Custom Object
I quickly recreate it with the same name, and sometimes I get this log:

Generally you only run one copy of a controller, or at least only one is active at any given time. As long as you were careful to write your code convergently then it shouldn't technically matter, but there really isn't much reason to run multiple.
