Docker swarm join with virtualbox: connection error 13, bad certificate

Docker Engine Swarm

Hello!
I’m working through “Get Started with Docker”, Part 4.
I created two machines, initialized swarm, tried to join worker node:

docker-machine create --driver virtualbox myvm1
docker-machine create --driver virtualbox myvm2
docker-machine ssh myvm1 “docker swarm init --advertise-addr 192.168.99.101:2376”
docker-machine ssh myvm2 “docker swarm join --token SWMTKN-1-65xbfd388nl61m4ip6qoplk0yqoze3qzq9ne9t00lmxbppt6oe-7f40hx9wn4tyu3b0nznsrqs2e 192.168.99.101:2376”

And got this error:

Error response from daemon: rpc error: code = 13 desc = connection error: desc = “transport: remote error: tls: bad certificate”

Can anyone help me with the issue?

Port 2376 is the docker daemon port, not the swarmkit port. Use 2377 as the port if you want to explicitly specify it, or omit it entirely in your --advertise-addr command.

For example:

docker-machine ssh myvm1 "docker swarm leave --force"
docker-machine ssh myvm1 "docker swarm init --advertise-addr 192.168.99.101"
docker-machine ssh myvm2 "docker swarm join --token SWMTKN-1-65xbfd388nl61m4ip6qoplk0yqoze3qzq9ne9t00lmxbppt6oe-7f40hx9wn4tyu3b0nznsrqs2e 192.168.99.101"

(you’d of course end up needing to grab an actual fresh token after you re-init the cluster)
