Docker Swarm + Tailscale

Due to conflicts between docker swarm initializing a custom network as the listening address, a tailscale image will run in a container to provide access to host as a proxy.

Steps to Initialize Tailscale Proxy (One machine in swarm cluster)

docker compose -f tailscale-compose.yaml up -d

#IPv4 Address of Container Running Tailscale (not local machine ip)
#Use this IP to initialize Docker Swarm
docker exec tailscale-proxy tailscale ip -4

To verify docker swarm has been initiated, check if port 2377 is listening

 netstat -an | grep 2377

Expected Terminal Output

$ netstat -an | grep 2377
  TCP    [::1]:2377             [::]:0                 LISTENING

Initialize Docker Swarm

#$DOCKER_IP is the result of docker exec tailscale-proxy tailscale ip -4
docker swarm init --advertise-addr "$DOCKER_IP" --listen-addr 0.0.0.0:2377

Join Docker Swarm as Manager

docker swarm join --token SWMTKN-1-3d5d79nba8q7gwtjhdawcl6eanznxn9fvhjrpcwjqx7vwfijya-65qikauecpqd0dbulv5rlnl7m 100.79.134.37:2377

Join Docker Swarm as Worker**

docker swarm join --token SWMTKN-1-2uhvdl1275df55gfuf8hheurl3r4j6wat80mh1b1w20h4xsrih-86evlwxl0mx9o0cuwompj6xtm 100.79.134.37:2377

Initialize Docker Swarm

TAILSCALE_IP=$(tailscale ip -4)
echo "Tailscale IP is : $TAILSCALE_IP"
docker swarm init --advertise-addr "$TAILSCALE_IP" --listen-addr 0.0.0.0:2377
