[GitHub] [incubator-streampark] libanglang opened a new issue, #2186: streampark support remote docker daemon

libanglang opened a new issue, #2186:
URL: https://github.com/apache/incubator-streampark/issues/2186

   ### Search before asking
   
   - [X] I had searched in the [feature](https://github.com/apache/incubator-streampark/issues?q=is%3Aissue+label%3A%22Feature%22) and found no similar feature requirement.
   
   
   ### Description
   
   condation:
   1. k8s use kata as a runtime which like a micro vm
   2. streampark deployed on k8s and run a kubenetes application task
   
   problems arising:
   streampark can't connect to docker-daemon when run a kubenetes application task, because the following conf in k8s yaml does not take effect
             volumeMounts:
               - name: volume-docker
                 mountPath: /var/run/docker.sock
                readOnly: true
   			 
   i guess kata container and host use their own kernel due to this socket file can't mount to kata container
   
   Why do I bring this up suggestion
   1. docker may not be installed on k8s cluster because k8s use cotainerd + runc
   
   2. we don't worry about kubenetes can schedule streampark to any node if we install a docker daemon on one node which cluster node can connect to it 
   
   
   proposal:
   1. install docker to support remote commutication
   [Service]
   ExecStart=
   ExecStart=/usr/bin/dockerd -H tcp://192.168.10.100:2375 -H unix://var/run/docker.sock
   
   2. streampark conf
   	docker:
       # instantiating DockerHttpClient
       http-client:
         max-connections: 10000
         connection-timeout-sec: 10000
         response-timeout-sec: 12000
         docker-host: "tcp://192.168.10.100:2375"
   
   
   ### Usage Scenario
   
   condation:
   1. k8s use kata as a runtime which like a micro vm
   2. streampark deployed on k8s and run a kubenetes application task
