Consul containers with protocol version error

I try to create a container for the consul and it continues to fail with this output, funny, I really don't think this is a mistake

Protocol 2 spoken by default, understands 2 to 3 (agent will automatically use protocol >2 when speaking to compatible agents)

The following is the command I'm using:

docker container run --net host --name consul-server -e 'CONSUL_LOCAL_CONFIG={"skip_leave_on_interrupt": true}' -e CONSUL_BIND_INTERFACE='eth0' consul agent -server -client 0.0.0.0 -dns-port 53 -bootstrap-expect 1 -ui -datacenter dc1 -v "/var/lib/consul:/consul/data" -data-dir /var/lib/consul

This is the only node new installation with the latest version from the registry, so there is no update or version mismatch with any agent / client occurring here.

Two things to fix. First, the -vvolume argument should be for the command docker, not for the command consul. Move it to the desired location:

docker container run -v "/consul/data:/var/lib/consul" -data-dir /var/lib/consul --net host --name consul-server -e 'CONSUL_LOCAL_CONFIG={"skip_leave_on_interrupt": true}' -e CONSUL_BIND_INTERFACE='eth0' consul agent -server -client 0.0.0.0 -dns-port 53 -bootstrap-expect 1 -ui -datacenter dc1

Also invert them (they are / host / dir: / container / dir)

-, Consul (.. 53). . : https://www.consul.io/docs/guides/forwarding.html, -dns-port 53 , :

docker container run -v "/consul/data:/var/lib/consul" -data-dir /var/lib/consul --net host --name consul-server -e 'CONSUL_LOCAL_CONFIG={"skip_leave_on_interrupt": true}' -e CONSUL_BIND_INTERFACE='eth0' consul agent -server -client 0.0.0.0 -bootstrap-expect 1 -ui -datacenter dc1
