The code:

  D --> C

The result:

All together (in Split mode).

How to create? Open Notion and add a new Code block with Mermaid language

You could choose the mode of the block: Split (both code and image shown), Code (code only) and Preview (image only).

For documentation of what could be used in code - here is a link to developers: https://mermaid.js.org/

I was working on the migration of about 10 container-app to the docker, and I wasted a lot of time taking a look for logs, you know if the service was able to contact other ones, etc.
I used to have about 3-5 terminals open, having 1 as a log console. But what I found? It's useless if you have about 10 containers flooding into it. Here comes the easy, lazy and fast project called Dozzle.

It features:

• Intelligent fuzzy search for container names 🤖

• Search logs using regex 🔦

• Small memory footprint 🏎

• Split screen for viewing multiple logs

• Download logs easy

• Live stats with memory and CPU usage

• Authentication with username and password 🚨

It's god damn small: RAM usage for the container was about 10 MB all the time.

Don't forget to star it :D
