I’m trying to create overlay network without using swarm mode;
When I try to create the network after required steps (up and running key-value storage and configure the daemon accordingly) it says this is “This node is not a swarm manager”.
I use docker version : 19.03.13 on CentOS 8.1.1911
All the examples for this practice nearly 4-5 years old, and official docker documentation (v17.09) has this part but current one has not.
Could this option be deprecated? Which means we can use overlay network only on swarm mode. If so is there any documentation/proof would you share with me?
If this is still open option what would you suggest to achieve that?
