Dockerself - runtime self-dockerizer

Presentation

dockerself is a program that creates a new Docker container, injects itself, and finally runs itself from within Docker.

For the record, I was working on pathwar (a security learning platform) and was trying to design the less-constraining way of creating new levels.

My current best idea is to inject a custom entrypoint when the platform starts a new container, instead of requiring the level developers to adapt their Dockerfile.

Additionally, to the simplicity that is added for a level developer, this pattern also has the advantage of always putting the latest version of the entrypoint, even if the image was not updated for a very long time.

$> man fred - fred man page

A good friend is starting his “piscine” at 42 today; it’s only his first day but he already made me the good old joke about “there is no man fred”.

If this joke doesn’t make you smile, this is probably because you don’t know what is the man command for developers and how much useful it is.

Explanation: man is the short for manual, when you type man something in a terminal, you can get some information about the command/function/thing.

More info on Wikipedia: man page, RTFM (read the fucking manual)

Unfortunately, as the fred command does not exist by default, running man fred will just raise an error:

$ man fred
No manual entry for fred

As a workaround, I created a manpage for fred four years ago. Today, I just added some install instructions and an example in the README file.

As soon as you install this manpage on your computer, you will be able to type man fred and have usefulvital! information about me :)

Good luck William for your piscine!
