Starting multiple services

[anastayaa]

When i'm trying to run more than one service, i'm getting the error:

unable to bind domain socket with id=0 (see --base-id option)
Error: exit status 1

I think this is related to Envoy proxy!!!

Summary

It's not possible to start a second dataplane (kuma-dp) on a Linux host.

kuma-dp fails with

$ KUMA_CONTROL_PLANE_BOOTSTRAP_SERVER_URL=http://localhost:5682 \ 
  KUMA_DATAPLANE_MESH=default \
  KUMA_DATAPLANE_NAME=node-client-1 \ 
  ./kuma-dp run

unable to bind domain socket with id=0 (see --base-id option)
Error: exit status 1

Steps To Reproduce

1. On the same Linux host, start kuma-cp and 2 kuma-dp, e.g.

$ kuma-cp run

$ echo "type: Dataplane
mesh: default
name: node-server-1
networking:
 inbound:
 - interface: 127.0.0.1:30000:3000
   tags:
     service: node-server" | kumactl apply -f -

$ KUMA_CONTROL_PLANE_BOOTSTRAP_SERVER_URL=http://localhost:5682 \
  KUMA_DATAPLANE_MESH=default \
  KUMA_DATAPLANE_NAME=node-server-1 \
  kuma-dp run

$ echo "type: Dataplane
mesh: default
name: node-client-1
networking:
 inbound:
 - interface: 127.0.0.1:30001:3001
   tags:
     service: node-client
 outbound:
 - interface: :40000
   service: node-server" | kumactl apply -f -

$ KUMA_CONTROL_PLANE_BOOTSTRAP_SERVER_URL=http://localhost:5682 \
  KUMA_DATAPLANE_MESH=default \
  KUMA_DATAPLANE_NAME=node-client-1 \
  kuma-dp run

2. The second kuma-dp run will fail with

unable to bind domain socket with id=0 (see --base-id option)
Error: exit status 1
