Figure 3-2-2
(3) Copy all the file directories under the "Tc6_a" folder to the "Tc6_b"
again.Go back to the master server and execute the following command to confirm that the cluster now has 3 nodes:docker node lsSee that there are now 3 nodes in the cluster. As shown in.Until then, the most complex and troublesome process is over. The rest is to experience the convenience of Docker swarm.Create test program Build Test RedisBecause there is a nee
