I am trying to set up an envoy for k8s. But the envoy service does not start and I see the following error in the log:

"The v2 xDS major version is deprecated and disabled by default.
Support for v2 will be removed from Envoy at the start of Q1 2021.
You may make use of v2 in Q4 2020 by following the advice in https://www.envoyproxy.io/docs/envoy/latest/faq/api/transition "

I understand that I need to rewrite the configuration in v3. I ask for help, as I am not very good at this. Here is my config.

static_resources:
  listeners:
  - name: k8s-controllers-listener
    address:
      socket_address: { address: 0.0.0.0, port_value: 6443 }
    filter_chains:
    - filters:
      - name: envoy.tcp_proxy
        config:
          stat_prefix: ingress_k8s_control
          cluster: k8s-controllers
  clusters:
  - name: k8s-controllers
    connect_timeout: 0.5s
    type: STRICT_DNS
    lb_policy: round_robin
    http2_protocol_options: {}
    load_assignment:
      cluster_name: k8s-controllers
      endpoints:

        - endpoint:
            address:

        - endpoint:
            address:
              socket_address: { address: ${CONTROLLER1_IP}, port_value: 6443 }
        - endpoint:
            address:
              socket_address: { address: ${CONTROLLER2_IP}, port_value: 6443 }
