Docker For Beginners: From Docker Desktop to Deployment

Learn Docker with this highly practical tutorial.
A year ago I tried to learn Docker but just wasn't ready for it. The tutorials I tried to follow were too comprehensive and "theory-based" for a first go at it. A year later I looked back and decided I would make a tutorial that would have been much more beneficial for me then.
In this video, we'll take a fun dive into Docker, learn some definitions, dockerize some apps, push them to Docker Hub, and deploy them to Digital Ocean.

Fresh install big sur, is docker a solution to install node npm etc globally and not run across the permissions issues when settings up a dev environment? Just wondering if this is something that'll replace that original install headache for noobs, or something that happens in addition to that original setup? Thanks I'm super confused, if I can avoid that whole homebrew headache I've went through and end up having to uninstall reinstall node and npm etc. Thanks

Tyle razy mnie oszukaliście skąd mam wiedzieć że znowu szykujecie kolejne pułapki nie możecie przepalić że jestem Polakiem mówiłem wam nie walcię w huja zemną. Wystarczyło mnie zapytć to bym wam powiedział że mam pierwszego. Tylu specjalistów rozkminia mi to zajęło 5 minut. Myślcie że nie wiedziałem gdzie co mam nie chciłem tam zaglądać bo wiedziałem że jest tego dużo i będzie właśnie to co robicie. Niechcenia z takimi ludźmi nic robić nie chce frunąć do Ameryki. Szkoda mi że nie wiedziałem o tej fundacji mogliście powiedzieć nic bym nie zatrzymał.

This is THE best Docker introduction out there, and there are a lot. Brilliant.

[@mastersquinch]

For anyone following this today, the first line in the dockerfile for the youtube-app needs to be FROM node:13.12.0-stretch . There were security fixes in newer versions of node which break this app.

[@oseitutu598]

This might well be the finest job done on a "docker explain" in the history of explaining Docker !! I am all set to go! Thank you for the awesome job you are doing !!!

[@Barbastarkk]

Spent all day yesterday scratching my head, while simultaneously trying to learn docker and makeing various flavours of baboon-like faces . At the end of the day i was left with a blank stare on my face feeling frustrated. After a bad night's sleep and two cups of coffe I stumbled upon this video and that changed everything. I can only speak for my self, but in my opinion your easygoing, inspiring and easy to understand approach to teaching makes this by far the best docker tutorial I've fond so far. Thanks a lot!!

[@blackwersus]

"I pulled some images and then I was like "where is my image?" " LOL that was exactly me - one of the hardest things for me to understand.

[@emmonspatzer5402]

I agree with Angry Bird. I have been studying, making installs, taking everything down to host machine with completely uninstalled Docker, bring it all back up again, doing a variety of Drupal GitHub and GitLab Docker clones, bringing then up locally in containers, etc. Learned more from your video, especially with the Visual Studio UI into doing all this, in an hour or two of watching and rewatching then I have in like a month of prior attempts of learning from reading and other videos. You are an excellent teacher in tone, style, pace, logical flow, ... Thanks so much

[@johndoe9450]

Dear Travis. I just deployed my first docker container to my affordable DigitalOcean droplet, and are now ready for developing and some demoing/showcasing using my favorite tech stack provided by images from Docker Hub. I now have a basic, working knowledge of Docker and now I feel ready to dive in to some of the more refined details of this technology and to use it in future projects. This is all all thanks to this great step-by-step explanation and demonstration. You really manage to take something that is dauntingly complex and make it seem less intimidating! Thank you so much for this wonderful guide! You did a fantastic job with it!

[@jesavius]

After 59 minutes and 29 seconds, there was no lie in the title. This is the man everyone cross-eyed on Docker needed and he came thru!!!

[@savashzaynal6502]

Sir, your a nerd, and I mean it as a complement to your knowledge but your also a rare kind of nerd that can explain something very pedagogically which is very very rare.

[@wkdj2522]

fantastic tutorial. i actually understand what the hell docker is now. i do think to truly appreciate this tool you have to have lived through the late 90's all the way up to a few years ago and actually have been involved in what it takes to do an application build, deal with CM and software dependencies, write multiple run scripts for various platforms and environments, and painstakingly create entire home-grown applications that run on servers to manage app versions, configurations, compatibility, even hardware load to some extent. believe me, docker may not do every single cool trick that's ever been invented -- of course, how could it -- but it appears to do 90% or more, and that means developers actually working on application code and not spending 50% of their time babysitting production.

[@kyabetsu4029]

at work, they asked me to start contenerize our applications and I'm juste a first year student doing his traineeship during four months. So i went to youtube to find help and I just found this video and even if it's a 1h video I'm releaved to find it. Thanks a lot

[@kyabetsu4029]

in addition it dates from 2020 so it's even better

[@markthrasher4548]

This is an absolutely perfect presentation on Docker. The level of content and how it is presented is second to none. The time index for the video is a very nice touch. I'm a definite subscriber. Thanks for the video!

[@bwandesky]

When I started this video I didn't have a Digital Ocean account, before the end of the video not only do I have one, but there are also 100 dollars attached to it. Let the games begin. Good content (excellent I should say). A good sign of a good tutor is when the student is enthusiastic to get started with assignments.

[@elkenoseteolvida]

Honestly, this is the best tutorial of Docker i have seen. Perfectly explained and clear.

[@ieronim272]

Truly the best docker tutorial on youtube

THE BEST Docker video on YT. I love how you explained each of those Dockerfile commands. Every other video seems to skip that.

[@theragavelan]

One of the best tutorial for docker I have ever seen. Thanks a lot. Please add Wordpress tag also to this video. This should rank high for Wordpress docker searches. Thanks

By far the best intro to Docker video I've found

I don't know where you've been hiding but, loved the way you relay information and the speed that you go about it. Gained a Sub. I might have found a mentor!!!!

Best Docker tutorial on KZbin

[@TheMegaEzio]

Went all over this on my own. I can only say now, that this video is very helpful!

[@rursus8354]

That overview first/details then reflection: right! That's a valid experience based teachers skill. Another reflection: each viewer has to know the things that you are talking about. The prerequisites for doing that is knowing bash, knowing apt, knowing VSC (which I essentially don't), knowing wordpress to the extent that the setup settings are known. If your viewers know all that, they may understand your lecture, otherwise not. Bash has to be assumed: otherwise demonstrating docker would be essentially meaningless. But apt? What does it do? What's the file working space on the host for your docker image?

[@fahadkhanchughtai3279]

Thankew, It was neither too complicated nor too easy. Just perfect.

[@bartbtsful]

Not even on the end, but already wanted to say as a beginner. This was excactly what I needed to quick start!. Thanks a lot!

[@MarkusAntony]

Excellent tutorial! Thanks! A small point, but usually for production apps, when building the Docker file you would use a specific version of Node (or whatever server you're using) instead of the 'latest' tag, and you would include both the package-lock.json and package.json file, so that whenever the script runs 'npm install', the container would have the exact dependency versions that work with the application. Otherwise, you could end up pulling the newer versions of the dependencies and those might not be compatible with the application.

[@ITSALLFYA]

Beautifully done. You have a gift. How-to videos on youtube have helped me a lot, but rarely are they done so well. Thank you.

[@OneTamadTV]

I am the same as you. I ditched Docker for a long time as the process is confusing... but yeah I totally learned and understand it now by your video... Thank you!!!

[@tesfayeyimam3700]

I always subscribe to a channel when I am convinced. Hence, I did. This video is really helpful for my project am fighting with.

[@eswara6964]

One of the best docker tutorial, you made it easy and clear to understand docker :)

[@AdmV0rl0n]

Many Thanks for the video. I appreciate the info and detail. Never a day goes by where I am not disappointed in docker. A simple idea at its core. If you use it daily and build a tool kit round it, then as per your video - one year later you can explain where you are at, and what your tooling is. It is in the as complex as other tooling. It actually requires a high skillset to deploy, secure, backup. And it requires like many CLI based world kits, third party tooling and heavy usage to get to speed and stay at speed. All the same, thanks for the video. Useful stuff.

[@liehian3395]

You should continue making tutorial. Amazing on how I am not skipping single second of this video. Good job man.

[@crhu319]

VMs are used for compatibility and provisioning for open ended development where you may need to install new things. Essentially to firewall stuff so it can be isolated from the host OS and customized heavily. Docker is used for provisioning for use, for incremental service driven development, where you are preparing for deployment. And where the OS is definitely known, fixed & singular. The main benefit being the ability to stack/combine containers. No VM can do that, you can't just merge VMs. There is no equivalent to the Dockerfile. You have to use installers. They overlap somewhat. If you have a choice, try Docker first.

[@emanuelechiarello1403]

Man i found myself exactly where you've been. Courius about this stuff but just didn't get it quite right... So well explained even from a newbe like me! Thank you :D

[@imranrentia]

Great Video Travis, I loved it how you showed everything with a live example and was very time efficient. you didnt waste a single second and every thing you explained in the video is useful.

[@chairmakerPete]

Fabulous video. Thank you. I'm utterly exhausted by the never-ending changes in modern development. Taking on docker today, guess kubernetes is next. Just as you feel like you're mastering the tech, it's all scrapped and the circus moves on to the next thing! It really was simpler in the 80s, kids!
