Docker Swarm over TLS

In this example, there are 3 servers with Docker installed on it. If docker is not installed, you can see the installation here. There will be one manager and two workers: Master – manager (IP: 1.1.1.1) Slave_1 – worker (IP: 1.1.2.1) Slave_2 – worker (IP: 1.1.2.2) Required ports for Docker Swarm to work: 2376 and … Continue reading "Docker Swarm over TLS"
