Looking for a diary note software in docker

hello friends in my 1st time in the forum I hope to learn and help as much as I can.

I’m not very knowledgeable, much less an expert in docker, but I only made my data server with OpenMediaVault 5, Docker and Portainer and have several containers that I use…

I am dedicating myself to trading cryptocurrencies and I am looking for a solution that allows me to use it in my docker and only use it myself or whoever I want to give access to…

I need something to use as a diary where I can write my notes and the date and time it was written and always reflected… I can also upload images (screenshots) or who knows… if even videos… and that a new post is accommodated under the 1st post and so on to have it as a follow-up…

I really like the idea of ​​the format of a forum where there is always the date and time of when something is written and above all a new post is seen below the 1st and so on, so it occurs to me that it be like a forum that can install it in docker.

can you tell me if there is any image like this in docker.hub
