regclient VS watchtower

But I'd suggest looking into if it's solved by other tools already, like regclient/regclient and their regsync features or something like containers/skopeo.

This is possible with the help of regctl.

I've been working on some stuff last couple of days to give me this function. Together with regctl I've got some drafts working.

with more options like auth and certs. Infra might include backing disk and LB; if you need to scale, run several and keep them in sync with one of many open tools eg regclient.

Also plenty of cloud services now have registries like GHCR, ECR, etc. which are basically pay per Gb.

I had a similar problem and ended up using regctl. You might have to tweak your docker config depending on the registries you use, by setting a file type ci/cd envvar with the name DOCKER_CONFIG

> 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!
