Docker Swarm Configuration for InkBlink

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

 

 

 

Join Docker Swarm as Manager
docker swarm join --token SWMTKN-1-02wfprfajaadqgikj5c1bkas15zgkfp6d314lqh8e2w98f8f1o-32839oqlr8e70n9mwuw10acmf 100.102.91.58:2377
Join Docker Swarm as Worker**
docker swarm join --token SWMTKN-1-0b6xiw3t04rexf66zno478qwc3dlldqqlta7jielsme50yzk9p-28lqq8xzxb9zko29rk2xo5ypz 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
If Tailscale Device is Not Recognizable by Docker ( WINDOWS  - WSL Alternative )
