I’m Træfik user since v1.4 but there was no caching system. I scrolled over the internet to know if any solution exists but nothing appear then I decided to write my own Træfik cache system. This talk it will be a feedback on Golang learning, issues, tips and tricks to start on this awesome language

I discovered Go language but didn’t have any time to follow multiples tutorials to learn it. But one day I discovered Træfik reverse-proxy project when I wanted to switch my infrastructure into fully dockerized one. I’m Træfik user since v1.4 but after many months using it I encountered an issue : there were no caching system in this reverse-proxy. I scrolled over the internet to know if any solution exists but nothing appears.

Then I decided to write my own Træfik cache system, but the main question was “Which language?”
- PHP ? Nah.
- Nodejs ? What a joke !
- C++ ? I didn’t learn this language at school and it’s really insane to learn.

Then I was on Træfik github repository when I decided to write it in Go. Another good point: that’s compatible with docker integration.

So I started the project and called it Souin
