In these talks I will give practical tips and tricks on how to effectively use Docker as a valuable tool to solve various problems or just use it for fun projects with all kinds of hardware and software! See my YouTube Channel with all episodes for more information.

EP01: socks5 proxy vs. port forwarding

   
Opening and forwarding specific ports per docker container is onl practical for a few containers but the more ports you open the more it becomes a hasstle and it is totally not clear which ports map to which container.  

A simple but very effective solution is to use a socks5 proxy. In this episode I will show how to install and use a socks5 proxy and what benefits it brings to use this solution which is that each container can be reached by its internal hostname which is the name of the container.

I will also show how to use username/password authentication and show how to use this combination in a secure practical way.

EP02: socks5 proxy with git (gitlab)

yotube

The proxy example in the previous episode can be extended to not only browsers but also for other protocols as well like like git. In this episode I will show how to use git over a ssh/socks proxy

EP03: socks5 proxy with Kubernetes (kubernetes-sigs/kind)

yotube

What makes this solution even more attractive is the fact that it can be used inside kubernetes as well. In this episode I will show hwo to install the socs5 proxyy via helm and hwo to access the dashboard.

EP04: generating dynamic hostnames

yotube

In the previous talk EP01: socks5 proxy vs. port forwarding I showed how to reach docker containers by their internal hostname but what if you want to expose a docker containter to the outside? In this episode I will show how to generate a externally accessable dynamic hostname for specific containers.

EP05: generate ssl cerificates for docker containers

yotube

Now that we can generate dynamic hostnames for docker containers, that opens the road for automatic generation of ssl certificates for those containers.

EP06: how to find the internal dns name of a docker container

yotube

In this episode I will show how to get the interal dns name of a docker container which is more than just the name of a container. Nothing fancy but still a handy trick to remember!
