swarmpit VS watchtower

So I need to setup prometheus, granfana, node exporter, and cadvisor before running this? All of the above give me everything I need to monitor a swarmcluster. And if I want multi-user access to the graphs, I’d configure auth in Grafana.

Further, if I were to monitor Swarm without the Prom+Grafana stack, I’d be looking at:

https://github.com/swarmpit/swarmpit

What is the value-add of Storm?

And then also look at Swarmpit https://github.com/swarmpit/swarmpit. It was last updated Aug 28, 2020 as well, so I don't know how active it is, but I also used it for a while before sticking with Portainer ultimately.

Kubernetes is a bit overkill. For my homegrown usage i use docker swarm. And use https://swarmpit.io to manage it

Specific to swarm but it might help soneone in a way https://github.com/swarmpit/swarmpit

In my experience, there are actually two platforms that do this pretty well.

First, there's Docker Swarm ( https://docs.docker.com/engine/swarm/ ) - it comes preinstalled with Docker, can handle either single machine deployments or clusters, even multi-master deployments. Furthermore, it just adds a few values to Docker Compose YAML format ( https://docs.docker.com/compose/compose-file/compose-file-v3... ) , so it's incredibly easy to launch containers with it. And there are lovely web interfaces, such as Portainer ( https://www.portainer.io/ ) or Swarmpit ( https://swarmpit.io/ ) for simpler management.

Secondly, there's also Hashicorp Nomad ( https://www.nomadproject.io/ ) - it's a single executable package, which allows similar setups to Docker Swarm, integrates nicely with service meshes like Consul ( https://www.consul.io/ ), and also allows non-containerized deployments to be managed, such as Java applications and others ( https://www.nomadproject.io/docs/drivers ). The only serious downsides is having to use the HCL DSL ( https://github.com/hashicorp/hcl ) and their web UI being read only in the last versions that i checked.

There are also some other tools, like CapRover ( https://caprover.com/ ) available, but many of those use Docker Swarm under the hood and i personally haven't used them. Of course, if you still want Kubernetes but implemented in a slightly simpler way, then there's also the Rancher K3s project ( https://k3s.io/ ) which packages the core of Kubernetes into a smaller executable and uses SQLite by default for storage, if i recall correctly. I've used it briefly and the resource usage was indeed far more reasonable than that of full Kubernetes clusters (like RKE).

I believer Portainer and Swarmpit would have this capabilties https://www.portainer.io/ https://github.com/swarmpit/swarmpit

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!
