 # Docker, Linux, Security. Kinda.
 
-Let's take it from the top.<br/>
-
 We will be exploring some Linux features in the context of a docker application container. Another way of explaining it would be to say we will talk about how to make more secure application containers.
 We will not talk about firewall and apparmor because they are tools that enhance security on the host in general and not specific to a docker application container. A secure host means a more secure application container but that is discussion for another post.<br/>
 We will focus on Linux containers since FreeBSD containers are still experimental(see [here](https://wiki.freebsd.org/Docker) and [here](https://github.com/samuelkarp/runj)). Yes, windows containers exist.<br/>

 Since we have the android phone's interface on another namespace the two cannot interfere with each other. This is pretty much how docker uses namespaces.<br/>
 Without a network namespace we would have to make a small VM, run a VPN on the VM and then make a socks5 proxy to the VM from the host and then have applications pass their traffic through a socks5 proxy with varying degrees of success.<br/>
 **_NOTE_**: since we are not running the script on a hook, you might blow out your net having two upstreams at the same time. In which case, run the script, then restart NetworkManager or whatever you have.
