caddy-docker-proxy VS Nebula

https://github.com/lucaslorentz/caddy-docker-proxy

It handles the routing to multiple dockerized projects on one server, by scanning docker compose files for labels and automatically setting up the required caddy configuration.

My go to is always this instead:

https://github.com/lucaslorentz/caddy-docker-proxy

Single label to a docker container and with correct DNS you’ll have an automatically managed certificate right away.

I have had a great experience with using this: https://github.com/lucaslorentz/caddy-docker-proxy

It combines caddy with docker-compose labels, making it super easy to spin up new projects that can immediately be exposed.

If you want a slightly heavier but more robust solution, caddy-docker-proxy[0] is a plugin that listens to the Docker socket and automatically updates the Caddy configuration based on Docker labels you add to containers.

I.e. it makes Caddy act a bit more like Traefik. Most of the time, you'll just add the label `caddy.reverse_proxy={{upstreams http 8080}}` to your containers and the plugin will regenerate Caddy's configuration whenever the container is modified.

I disagree, Caddy works great in Docker. See https://caddyserver.com/docs/running#docker-compose, and CDP is a project that autoconfigures Caddy from labels https://github.com/lucaslorentz/caddy-docker-proxy. Regarding plugins, it's super simple to write a Dockerfile to add plugins, we ship a builder image variant that can be used to compile in any plugins you want.

This way, Caddy will buffer the request and give 30 seconds for your new service to get online when you're deploying a new version.

Ideally, during deployment of a new version the new version should go live and healthy before caddy starts using it (and kills the old container). I've looked at https://github.com/Wowu/docker-rollout and https://github.com/lucaslorentz/caddy-docker-proxy but haven't had time to prioritize it yet.

Docker labels support is available via a plugin https://github.com/lucaslorentz/caddy-docker-proxy

I am trying now for some Days to use a Caddyfile additionaly to the auto generated files from lucas lorentzes caddy repositroy. https://github.com/lucaslorentz/caddy-docker-proxy

(I am a Nebula maintainer.) We recently merged support for gVisor-based services, although it's very new, and I don't know of much experimentation that's been done with it yet: https://github.com/slackhq/nebula/pull/965

Nebula, originally from Slack[0].

Wireguard rightly gets a lot of attention, but Nebula is a really simple and easy to deploy mesh network that is often overlooked.

It does lack a management GUI and that stuff is very much DIY.

Fair enough about the android mobile client... My use case only involves meshing linux appliances across various networks so we only need the nebula core binaries which are under MIT license

https://github.com/slackhq/nebula/blob/master/LICENSE

That's not at all confusing with Slack's Nebula. https://github.com/slackhq/nebula

Sounds like a bunch of your pain points are just related to needing an online CA or ICA. But, looking through the Nebula docs I don't know that it supports things like CRL addresses where you could host the CRL, or OCSP responders. Someone got support for an OCSP responder but never submitted a PR with completed code: https://github.com/slackhq/nebula/issues/72

Nebula is a scalable, cross-platform overlay networking tool focused on performance, simplicity, and security. This portable tool is equally adapted for linking a small number of computers or scaling to connect tens of thousands. It integrates encryption, security groups, certificates, and tunneling into a powerful, cohesive connectivity solution. Thanks for the recommendation go to jmeador42.

Replying to my own comment as I can no longer edit it:

The folks over at Slack had an interesting discussion regarding the the "battle of the VPNs" article published by Netmaker I sourced in my parent comment:

https://github.com/slackhq/nebula/discussions/911

Interesting. I thought recognized the logo, apparently seems to be a commercial support offering of https://github.com/slackhq/nebula and they support the "nebula" iOS app. I had been using for nebula/defined in the past.

Nebula: Is super easy to get running. It uses an interesting angle, working on the service and not just the device level. Unfortunately their NAT support seems to be still quite problematic and I am not going to maintain all those forwarded ports manually. There is a PR to support PCP but even if that ever gets applied I am not sure how well that will play with older routers. While it should be battle proven at slack, the community seems to be not that active. It still has the in-house tool that just got released.

The catch is that I want this to be reliable and fault tolerant, so if some of the game servers in the network go down, the remaining online servers should still always be able to receive broadcasts from any other online server. The servers can also be in multiple geographic locations and I am planning on using a mesh overlay network like Nebula to connect them. Essentially each pair of online servers will likely have a secure link between them that goes directly through the underlying network.
