How many containers should I run on the 5$/m droplet ?
I'm just getting started with docker, I created my first droplet (via the Docker pre-built set-up) and have pointed two domain names to the droplet's IP.
The first domain would be my personal site to play around with, so I would like to test different images/blogs etc. - for the moment I will set it up with Ghost using the official Docker Ghost image.
The second domain will contain 2 sub-sites for my other half and her sister to create a simple portfolio/blog site... for the moment with Ghost but I will possibly switch to Wordpress as it's easier for an end-user.
Therefore, I plan to have at least 3 "portfolio" sites running 3 Ghost images or 1x Ghost + 2x Wordpress.
After checking just the 3 Ghost images running, alongside Nginx image and Docker-Gen - I seem to use 95% memory, I suppose it's normal but I don't know of any ways to test load.
Will I be able to run other sub-sites from the second domain?
Also what is a good set-up for dockerfiles and directories for each site ? I figured I would follow:
With a docker and site folder inside, like so:
Although I'm still trying to wrap my head around how a Data Container works, I need an easy way to login and update or tweak files like adding a new theme or plugin to ghost.
Thanks in advance!
