I currently have a VPS (on Contabo) which I use docker containers for self hosting, my web front-end is using Traefik to reverse proxy and I am using Cloudflare for DNS. My problem is the server is over utilized. I’d like to fix this by building a 2-3 node Docker Swarm to spread the load. I am still in the process of learning Docker, but I have created a simple swarm in the past. Unfortunately, it lacked the ability for me to use the containers (with the same IP) as I moved them around. My questions are: How do I make would I enable the seamless use of a container publicly as I move them from node to node?I know there will be a moment, but I don’t want to need to change my DNS each time a container gets moved. I know I would need a shared IP, but I am sure what to use it on. Does Traefik provide some type of HA? Do separate instances need to run on each node? Does anyone have any links to share on tutorials? Does Docker Swarm move containers automatically to balance resource use or is that more a Kubernetes feature? submitted by /u/EZarnosky [link] [comments]
