I'm trying to figure out a way to consolidate the logs from all the containers I'm running into a single console view, organized by each container. I came across a setup that seemed really effective, but I need guidance on what tools or scripts I should use to get it done.

Consider setting up a log shipper like Fluent, which can pull logs from your containers and send them to storage solutions like ELK, Grafana Loki, or Splunk. This way, you can always have access to your logs and analyze them without having to tail each one manually.
You can actually do this with plain `kubectl` as well. Just run: `kubectl logs -f -l app=yourapp --all-containers=true` to get a live tail on multiple logs. If you want something a bit more streamlined, tools like **multitail** or **Dozzle** might also work for you! Here’s a [link to multitail](https://www.vanheusden.com/multitail/) for more info.
If you’re using Kubernetes, **stern** is a great option for tailing logs from multiple containers at once. It aggregates logs from all containers matching the criteria you set. You can also check out **kubetail** for a similar experience, making it easier to see what's happening across your services.
You can use **tmux** to create a custom multi-pane console where each container's logs can be displayed separately. It's a handy little setup that allows you to monitor everything in one place! Here's a [guide to get started with tmux](https://opensource.com/article/20/1/tmux-console).
Tmux might be an old-school choice, but it gets the job done! Most people today aren't familiar with it.
Stern really simplifies things, definitely worth checking out!
