docker-swag VS watchtower

I have a NAS on .0.181 and a swag container (on a different port than nginx) on .0.180 that points to my public facing services. For obvious reasons, I don't want my public domain to point to any other ports/addresses on my home network. Additionally, as elegant as swag is, it requires authentication and so won't work for simple local DNS. I now have one local domain for each server and an nginx instance on each that resolves to my different services on each.

OP is even linking the Github... https://github.com/linuxserver/docker-swag

I have an UnRAID server with a few services (Jellyfin, Nextcloud, etc.) running on it behind Linux Servers' SWAG reverse proxy container, which is built on Nginx and Let's Encrypt. This is pointed to a DuckDNS link, which is then pointed at my domain with a CNAME. So I can access Jellyfin, for example, at jellyfin.mydomain.com. A few weeks ago, due to seemingly unrelated issues, I got a new modem/router, an Arris SURFboard G34. For the first few weeks, everything was working as before. But now, when on my LAN, I can't get to my services at the proxied domain. It times out every time. There are no errors in SWAG's logs, nothing seems amiss in the router's web interface, and the services are available both at their IP:port address and, when not on my LAN, I can access them at the domain no problem.

Reverse proxy, probably? I use Docker SWAG, setup here, with DuckDNS and it works really well for me. There are of course many ways to reverse proxy, as I linked to earlier.

> if you're using the docker image, upgrades are a breeze. Just bump the tag on the image, redeploy, and you're done.

Or you could just run Watchtower beside it and it will automatically update your docker containers. https://github.com/containrrr/watchtower If you are OK with automated updates.

So i primarily use containers on my local machine walled off from the internet, so it's not a big concern for me. Watchtower [1] is popular among home server users too which automatically updates containers to the latest image.

For production uses I think companies generally build their own containers. They would have a common base linux container and build the other containers based off that with a typical CI/CD pipeline. So if glibc is patched, it's probably patched in the base container and the others are then rebuilt. You don't have to patch each container individually, just the base. Production also minimizes the scope of containers with nothing installed except what's necessary so they have few dependencies.

You can use Watchtower (https://containrrr.dev/watchtower/) that solves problem of manual pulling on VPS.

I checked https://containrrr.dev/watchtower/ and Arguments, but I don't understand where to attach that using portainer.

Again, there are options to automate some of the burden here by using tools such as Watchtower.

Have you ever deployed a Docker app on a server, but everytime you push a new version of your image to a Docker registry you need to manually restart your app? If you want to automate this restarting, this blog post is for you! I am now going to show you how you can do this with literally 1 simple command using Watchtower!
