This series was really fantastic. There is a huge difference between someone who is literally teaching concepts the way you are and someone who makes a quick YT tutorial on how to do something simple. Both can be valuable, but I find your method to be far more valuable for me.

You are awesome!!!.
I went through ur bash and docker.
I will go through others, too.

I have never seen videos, which are so well explained.

Real respect!!!.

Amazing - Thank you for the whole series. Very well done!

Easily the most practical tutorial (and all your other tutorials as well) for someone just spinning their own home server. Far better than other tutorials.

[Nikongen]

Great Series :)
I really enjoyed watching, again since this time I'm actually playing around with docker.

What I am missing though is Part 8: How to add persistent storage to a docker container, or how to access a filesystem where I store my website files, so these are not deleted when the container stops running or restarts.

Used this tutorial to set up nginx inside of docker, hosted on a proxmox (after watching the series) ubuntu LXC container that was created/managed through ansible (after watching the series). Needed nginx inside my homelab as a redirector as it's becoming difficult to keep track of all of my homelab servers a bunch of other stuff). Thank you for the easy to follow content, looking forward to continued learning facilitated by the time you are devoting!

You rly saved me with the skip prompts thing! Thanks!

[gavinxu]

Such a great introduction to docker with detailed explanations and examples, not only showing just the commands, but also the logic of doing that!

Sorry to see this series end. This really helped me figure out what was going on with getting into and out of containers. I'm trying to move from vm environments to docker containers, and this series was an excellent start. I look forward to more of your Docker videos!

[coletraintechgames]

this was I want more. After watching this, I went off in search of more... and realized how good this was and can find nothing of this quality.. where is #8? and 9 and

Three questions:

1a) @15:39 "being prompted"
Your solution worked. But which of the 12 geographical choices (when you were prompted) did the "apt install" (contained within the file "Dockerfile") choose, when automating it to not ask?

1b) What if you wanted to choose a specific geographical location (choose a specific number from the 1 through 12 list)?
How do you automate which choice is chosen?

2) Where are the docker images located?
Those images are downloaded from a server. Where does docker store them? What directory? What filename?

3) Are containers able to access your host machine?
For example, if I want to run an untrustworthy app, script, visit a sketchy web site, test something, etc, can it be done safely from a container, where any damage would not escape the container?


Thank you.

[fedebaez]

thank you master, this course was great!

[ronnierush]

Many Thanks for the Great tutorial series. I now know a small something about what Docker is and its workings. It does seem a bit none intuitive compared with using a VM but I guess that could be that I use VM's all the time and I am no pro at that either :-)
