I've been watching a lot of Christian's videos over the last week in random order. The content is informative, accessible and well paced. But what I love the most is watching how the homelab just quietly grows over time in the background! ♥

[@GorkemYildirim]

I started using docker in OMV5 and mostly adding stacks with docker-compose files but sometimes it is necessary to use these basic commands. Thanks a lot for the detailed tutorial.

[@AkamiChannel]

Your explanation of Docker is great. Many videos out there don't really explain what the point of it is in the first place. Good job!

[@christianlempa]

Many thanks!

[@ChrisPinCornwall]

Thank you so much. One of the best IT resources on YT, doubly impressive as you're not working in your native language. Respect!

[@christianlempa]

Thank you so much 😃

[@TechWazza]

Thanks for the explanation. Your description of persistence was helpful.

[@christianlempa]

Thanks ❤

[@hangchen]

Been searching and this is the best docker beginner video

[@christianlempa]

Wow, thanks!

[@tomferrin1148]

Very useful tutorial. All the Docker basics are well explained.

[@christianlempa]

Thanks mate! :)

[@mikhailmakharadze8604]

Thank you Christian, video is very useful.

[@GadgeteerZA]

Thanks, this finally explained persistent storage and volumes in an easy way.

[@christianlempa]

Thanks mate!

[@linearburn8838]

I love docker

[@christianlempa]

Me too! 😎

[@nourkonsol3162]

thank you,, Simple and Clear..

[@MarcelloRademaker]

Keep up the good work and a big thank you from Amsterdam

[@christianlempa]

Thank you so much! And yea, I will do :)

[@pandukaliyanage]

This is a hidden gem! OMG i love you bro! the best youtuber i ever met!!!!!!! keep grinding! i need more!!!!!!!!

[@christianlempa]

Haha, thanks, I'll do 😁

[@catharsis222]

Really quality material! I feel I will get better watching these videos. This will reinforce what I already know and Im definitely going to pick up some new ideas here. This is like a long form format of David Bombals videos. I found this just by putting Docker Networking and I look forward to see everything

[@christianlempa]

Thank you so much! It really makes me happy because David B. makes great videos, professionally produced and it's nice to hear you get some value out of mine, too 😁

[@catharsis222]

@@christianlempa it finally hit me, this reminds me of that Maximilian guy from Germany who does Academind, but hes more of a JavaScript guy, and this channel is exactly what I do in my life (Networking/Cloud/Python). This channel has potential.

[@catsbycamden6670]

First off, your tutorials are amazing! I am new to this whole shebang, would this nginx example be accessible from the public internet?

[@ivanivanou7330]

Very useful tutorial for beginners. thumb up!

[@christianlempa]

Thanks mate

[@nshutiherve4403]

This was so helpful Thank you

[@christianlempa]

You're so welcome!

[@boesit]

That was a super cool introduction - thank you

[@christianlempa]

You're very welcome!

[@boesit]

@@christianlempa I would love if you make a video and discuss how to monitor +several Docker/Portainer installations and the containers. Just an idea ;-)

[@roarcerth3681]

Great explanation!

[@christianlempa]

Thanks mate

[@Technik500]

great channel, love your videos! one thing with regards to this video is explaining about dockerfile and creating an image. didn't see you had a video on it?

[@christianlempa]

Thank you so much :D

[@ikemaduforo]

Christian, This is good

[@christianlempa]

Awesome!

[@fishy007]

Loved this explanation. Thank you! I was confused as to how a container would store persistent info, but you've explained volumes well. Also, what is the status bar app I'm seeing at the top of your screen? The one with the folder links and CPU/RAM usage? I love the look of it.

[@christianlempa]

Thanks :) I'm not using the bar anymore but its a rainmeter skin you can find on my dotfiles github repository

[@Chathumal2011]

Nice video. I see that your channel is somewhat new. The way you present these videos, mark my words, this channel will be a super tech channel. By the way as a telecommunication engineering student, I would like to work with python,linux.networking etc all these things are gathered in this channel. Thanks for making such a channel. I wish you good luck!!!

[@christianlempa]

Thank you so much! It makes me happy to see that you believe in this channel and it will be successful, I'll do my best to make it happen 😀

[@maxsalcedo7190]

awesome content!!!!

[@christianlempa]

Thank you 😊

thank you

[@paulmaydaynight9925]

question: id like to start 'slax' as the base image but its not a docker hub option yt deletes this u r l post so reconstitute this slax o r g slash customize p h p how do i use that Tomas M -the original livecd creator- slax image based on ram loadable modules in docker , deploy docker slax

[@_Roland]

sehr gut, danke!

[@christianlempa]

Sehr gerne 🙂

[@badrulv4427]

can you have the commands you used in the tutorial in a script available here thanks

[@gt3911]

@6:56 what is this terminal your used to access the VM?

[@christianlempa]

I've done a video about my WSL setup here: kzbin.info/www/bejne/pXeZmH-vnbZ3mtk

[@HEWfunkingKNEWit]

Man I watched so many videos to try understand what you explained in this video

[@christianlempa]

Thank you! I'm glad my content helps you 😉

[@YannMetalhead]

Good video.

[@christianlempa]

Thx

[@devendrahyalij5724]

Your Awesome ❤️

[@christianlempa]

Thanks, you too 😊👍

[@judeleon8485]

Thanks Christian. This was really helpful. However, I want to ask why you say we need a linux distribution to run dockers? Though I am new to dockers but I'm aware that I can simply run docker on windows from my command prompt without any linux installation besides having wsl2 installed

[@christianlempa]

You can't run Linux Containers on Windows and vice-versa, solutions like WSL are only possible to do this because they run Linux in a VM inside Windows. That's what I meant.

[@Dj-WannaBe]

I know that the video is old, but now i came to see the docker ... what is the name of the shell app you use ? Because dont look like VSCode... How you customized it to show those icons,and the AI autocomplete ?

[@christianlempa]

I did a full video on that: kzbin.info/www/bejne/pXeZmH-vnbZ3mtk

[@JosephWhite-dm8we]

[@mildmildfire]

I am a bit confused with how much resources does docker require for running minimal load on a vps server. Is 1 GB ram on a vps even enough to run docker itself?

[@christianlempa]

Docker itself doesn't have much overhead, it's very efficient

[@bafd19991]

What terminal are you using?

[@christianlempa]

I'm using Windows Terminal and zsh in the wsl. I will upload a video on Monday about my complete terminal setup so stay tuned 😊

[@fbifido2]

Note: sudo docker image rm

[@christianlempa]

Thanks! :)

[@Selbstdenkender]

Love the German accent :-) Well explained as well!

[@christianlempa]

Thanks :D

[@F2H16]

Hi Christian, thanks for the great content. I could have concentrated or enjoyed it even more without the background music. That's a personal preference though.

[@christianlempa]

Thank you so much! I like my music, but I must admit, that it was a bit too loud on some of my older videos :D

[@DerJP]

bester mann übelst sympathisch

[@christianlempa]

Danke 😊👍

[@ALN2006]

what is this windows theme? I assume xcad is Your username

[@christianlempa]

Yes that's right ;) I created my own rainmeter plugin at this time

[@AkamiChannel]

What I get confused about sometimes is how SSL gets taken care of with a docker app and with a load balancer. Let's say I have a little app that I want to work with low latency here in Japan and also in North America. I've never done anything beyond single-instance apps. So I'm interested in learning how to deploy multiple instances in a few different regions. How all of that is going to play along with say, AWS's S3, DynamoDB, and CloudFront for example becomes very complex.

[@christianlempa]

Good point. Docker really gets interesting when deploying applications in cloud environments. We will have look at that when I make videos about kubernetes and cloud deployment of docker applications. Stay tuned for more content about that 😎

[@petergfrazier]

So like docker is PLAN9...

[@devendrahyalij5724]

i want that wallpaper

[@christianlempa]

Haha yeah that's awesome 😎

[@snegmatron]

Ahh, is this German efficiency at work, no offence if not German? Great, clear tuition giving the foundations of why something is being done. Although new and struggling with Linux, I can see the rationale. No smart-A comments, or ear shattering noise (not music) 100%

[@christianlempa]

Thank's, you're right I'm German 😂

[@them4z]

It's spelled "daunlohd", not "dohnlohd". 😉

[@CottonInDerTube]

There is NO "seequal" in MySQL. Structured Query Language. There IS NO "SEEQUAL" =)

[@christianlempa]

I'm still used to it man ;)
