docker-autocompose VS watchtower

But there is this little tool docker-autocompose that can read the configuration of your current containers and export that into a docker-compose.yml. It probably wont work 100% perfect for every possible container config, but its worth a try and it might save a lot of time when making the switch from run to compose. Good luck!

You can try to use docker-autocompose to read the configs of your currently deployed containers and write them into a compose file for you.

There are different registries, Docker Hub, Quay (quay.io), GitHub (ghcr.io), Linuxserver (lscr.io). Then there is the image name and then the tag (//:; for example lscr.io/linuxserver/plex:latest). The tag and the registry won't matter too much for you (tag I guess you use latest), because most maintainers like Linuxserver push the same image to different registries. So it doesn't really matter if you use lscr.io/linuxserver/plex:latest or just linuxserver/plex:latest or ghcr.io/linuxserver/plex:latest. What does matter is if you use the linxserver or the plexinc image. If you run docker container ls in your terminal, you can see which image you are using. You could then run docker container inspect to get a json config of your plex container and volume mounts etc. to use that to create a docker compose file for it. There are also tools that do that automatically for you, like this: https://github.com/Red5d/docker-autocompose/blob/master/README.md This way, you can use docker compose to start/stop/update and have a permanent config which you can easily migrate to a new NAS/server.

I converted existing docker run via https://www.composerize.com/ (since I had them written down in text file) , you can also use https://github.com/Red5d/docker-autocompose (examples on very bottom) to convert existing containers to YML file.

> 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!
