Cannot run 2 instances of "az connectedk8s proxy" on the same VM

[dschveninger]

Describe the bug

The "az connectedk8s proxy" does not allow a client proxy to run more than one instance on a VM. We would like to be able to run multiple proxies by specifying client port number.

The following code prohibit the "az connectedk8s proxy" from running multi-instances on a VM.

The code only allows a single process running:

1. Does not allow the Client port to be set.

   azure-cli-extensions/src/connectedk8s/azext_connectedk8s/custom.py

   Line 1801 in c984268

   if(clientproxyutils.check_process(proc_name)):

2. Check for a process name only.

   azure-cli-extensions/src/connectedk8s/azext_connectedk8s/_clientproxyutils.py

   Line 125 in c984268

   def check_process(processName):

What is the process for getting an idea like this evaluated?

Allow to specify client port and run instance of proxy on different local ports against different clusters.

Any update on this? Would be very helpful for "az connectedk8s proxy" to run multi-instances on a VM

Starting with extension version 1.6.8, you should now be able to run multiple instances of az connectedk8s proxy on the same VM if you specify different ports for each. You can do this using the --port argument. Note, the proxy will also use an internal port, which will continue to use the default for the first proxy instance you create, but will then pick the port numbered 1 less than the option you specify with the --port argument for subsequent proxy instances.

Note, you will then need to set the kube context to the cluster you want to target to change which proxy is being used/ which cluster you are targeting.
