Support injection for applications with statefulset but no deployment.

[snyderpa-owl]

I have a fairly simple use-case but struggling to work out the series of commands to make this happen. In a dev environment with several namespaces each serving a php web app declared using a statefulset configuration, I want to reverse forward port 9003 to my local xdebug client. I expect

ktunnel inject deployment <name_of_statefulset> 9003 -v
INFO[0000] Injecting tunnel sidecar to default/owl-app  
FATA[0001] failed injecting sidecar: deployments.apps "owl-app" not found 

to use the existing statefulset or for ktunnel to provide an ktunnel inject statefulset command.

If there is a workaround or a supported way to accomplish this, help would be appreciated.

Thanks.

Hi @snyderpa-owl, the current implementation doesn't support injecting to StatefulSets, what you can do is expose a service with the port with the ktunnel expose and then direct your php application's xdebug remote host to the address of the exposed service

Thanks @omrikiei here is what I am trying -- can you help me get past this?

% ktunnel expose -v xdebug 9003:9003
FATA[0001] Failed to expose local machine as a service: error creating deployment 
% ktunnel expose -v xdebug 9003     
FATA[0001] Failed to expose local machine as a service: error creating deployment 

I am able to create a simple deployment using kubectl apply so I can confirm I have correct auth and kube installation.

@snyderpa-owl which k8s version are you using? I want to try and replicate this

Connected to an AWS EKS cluster I am using this:

% kubectl version

Any updates on this I need something similar for a DaemonSet

That would make sense for my use-case as well
