From Zero to Docker - Tutorial for Beginners

[@JonnyLangefeld]

Probably the most common question on here is how I set up my terminal. Here you go: kzbin.info/www/bejne/amnJnoh9eK6dmZI

[@ades3967]

This is the best Docker for beginners tutorial I've ever seen.

[@phaser2679]

The best docker beginner tutorial I've seen! You've managed to explain the concepts and all the questions I've had in my head. Thanks so much, Jonny! I've been using VMs & Linux for years but when it comes to Docker, I just couldn't wrap my head around it. But you helped settle that in 15mins! Awesome!

[@JonnyLangefeld]

Thank you so much for this comment!

[@funkmasthafred]

I've been looking at a fair few intro videos to docker now and this is by far the best one I 've come across. Short and to the point. Very helpful! Thank you:)

[@SaraSaraSaraSara27]

I have watched SO many docker videos now, and this is hands down the best one

[@JonnyLangefeld]

Wow thank you!

[@aliakbar1062]

Very detailed video!!! It's an amazing tutorial that makes me understand what docker really is. About docker images and containers that you assumed as classes and objects. Thank youuu!!!!

[@bedney45]

Thank you Jonny. This was exactly the level of detail I needed. I knew almost nothing about Docker before and I feel like I can at least begin my more deep learning process now. Cheers!

[@waellerbe]

Thank your explanation of *Docker*. With each new video I watch on this subject, my interest in the value of Docker continues to grow. So happy to have learned about this incredible resource for Mac, Windows and Linux.

[@shettyshivprasad]

Wow, so much information shared in those 16 mins. It is better to watch it again if you feel overwhelmed. Thank you very much for your time and efforts.

[@haseebpavaratty6249]

This is the only video that I found easy to understand. Thanks man.

[@igniteresearch3412]

Awesome ! I came here with zero knowledge in docker and your tutorial helps me allot Now I have created my own image and exposed the port too ... your awesome buddy ! No words Your Great

[@waqar_asgar__r7294]

Thanks. No words spared. Brilliant tutorial.

[@tedthetnaungsoe]

Always wanted to get started learning Docker. But every time I go to Official Page, was so confuse and stop after spending an hour or more on official Page. Luckily, this time, I saw this video and after spending 16minutes, I have now clear understanding of what docker is and how this eco system works. Thanks so much and appreciate your efforts. Now time to dig deeper ....

[@JonnyLangefeld]

So glad to hear, thank you!! :)

[@nikhiljoshi8630]

Jony L - You are brilliant, this video helps me understand what is Docker from ZERO! Too good, thanks a lot.

[@kytv9000]

Yes, this is the tutorial I find very clearly explained with key info about docker for beginners. Thanks.

[@AndrewGrosmanEnUfor]

Was probably the most helpful explanation from setup to running and creating your own simple images. Everyone else so far has started out with stuff non-programmers don't understand (like me). The website posted is also very in-depth. Thank You!

[@nerdsofgotham]

Absolutely wonderful introduction! Just a note for Linux users. You may need to add yourself to the "docker" group. Otherwise you may get a permission denied error like this: docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post %2Fvar%2Frun%2Fdocker.sock/v1.32/containers/create: dial unix /var/run/docker.sock: connect: permission denied.

[@JonnyLangefeld]

Thank you for the feedback and the useful addition!

[@kenjohnsiosan9707]

making an analogy to classes/object vs images/containers makes it clear to me. thanks :)

[@edust83]

Yeah me too!

[@JonnyLangefeld]

Glad it was helpful!

Best introduction video about Docker I have ever seen, thanks!

[@purnendusekharrath6377]

I am speechless ..by the way the videos is presenting..Such a wonderful video..any layman can understand and starts on docker after seeing this.Thank you very much to share this.

[@JonnyLangefeld]

Thank you so much for the feedback!

[@steveburrus9347]

PLEASE PLEASE don't get carried away with yiur pra ise of him.

[@sebipoiana1768]

Purnendusekhar Rath I agree! Simple and on the point! Thank you! :)

[@henriqueferreira9470]

great video! Fast and to the point! No need for a 45 min video!!

[@imshafay]

This video deserved Million Views. and +1 Sub.

[@JaiPandit1989]

Now I have understanding of what is Docker! thanks for short simple and very informative tutorial!

[@bobboberino8923]

Great tutorial, simple yet enough to get started.

[@goosefeathered]

This was absolutely wonderful and extremely helpful. The one thing I wish to be a trend for ALL tutorials, not only this one, would be an explanation of abbreviations (flags generally in this case) and what they mean. Relative to this video, it would be helpful if the flags for docker could be named and explained when run. Excellent resource and I really appreciate it!

[@JonnyLangefeld]

Actually that's a very good point! I'll try to included that from now on. (Wish I had read your comment before the video I just uploaded 😄 oh well, next time)

[@Shambo271]

Clear, concise, short! Thank you, Jonny.

[@SaumitraVideos]

Thank you so much Johnny, this is one of the best videos I have seen - clear, concise and just what most of us want! Thank you once again!

[@bLd321]

Thank you. Very helpful. Great starting point for total newbie.

[@bondinthepond]

Awesome.....Docker basics in just 16 minutes!!!! Great job!! Thanks a lot.

[@fvgoya]

Best beginner video ever about docker!!! Thank you very much!!!!

[@javierlopez5877]

I rarely comment on youtube videos, but I must say Jonny your'e great! Very nice way to explain everything, and the voice is really calming too!! The video edit is also great! Keep it up, I'd be happy to wach more from you. I'm suscribed!

[@chaitanyaPDF]

Thanks for the wonderful tutorial, Jonny. You made it so simple. You should make more videos.

[@feikezhang3354]

Thank you so much! I have read some tutorials about docker, and yours is the best!

[@majicboca]

Excellent job of explaining the fundamentals of Docker in such a concise, step-by-step way. Thank you very much Jonny for taking the time to share your knowledge. Kind Regards.

[@Deepakkumar-wy3mw]

This video is really Good and it helps a lot for the beginners. It is pretty simple to understand and start working with the docker technology. Thank you for making the very interesting video.

[@adianrasmi6344]

Thank You; i have question , i have container for mininet,ryu and flowvisor , how can i add a new topology or file to it I do not how could help me, please

[@salar0049]

Thank you for the tutorial, I managed to install docker and learn some basics for the first time. well done

[@BenKadel]

Great tutorial mate! Very clear and informative

[@luckbychance3179]

It’s very very much helpful for a kick start thanks a lot. Only I did not get you at the point 10.45 where you have ran the command docker run -it --name my-linux-container --rm -v /Data/Private/Documents/Projekte/learning/Docker:/my-data ubuntu bash Question here is : 1) why we need (one of local path i.e. in your case) /Data/Private/Documents/Projekte/learning/Docker, and what we are trying here 2) I see there is some file inside my-data folder, from where those files came in. Is it already present there or it came automatically.

[@sagarkapasi099]

Thank You; Went Straight Into My Head.

[@AmanRaj-gs8pt]

awesome explanation understood the concepts clearly, great job bro

[@trustybee1449]

Very well explained! Thanks for the video! Expecting more! :)

[@jhpang8155]

Good explanation , I get the idea instantly after finish your video. Thanks man, good job!

[@atanudebnath9173]

Hey Jonny, Could you please brief about more on all the terminologies below --Docker Image --Docker Container --Docker Registry / Docker Hub --Docker API --Docker Engine

[@JonnyLangefeld]

Hi Atanu, thanks for your question! So I was trying to explain the first two - Docker Image and Docker Container - in the video from 0:48 onwards, do you have additional questions to that? In regards to the other bullet points: - The Docker Hub is just there to host your own containers. You could think of it as a github for docker. All the big open source software vendors have usually also an official docker image on the docker hub, such as apache or tensorflow and heaps of others. But also you yourself could just create an account on the website (linked in the description) and host your own containers (let's say a unique combination of two softwares or even your own software) and others could download the images from there. - The Docker API is just there to automate the process of building and destroying containers. So you could imagine a web frontend to interact with docker containers (wich actually exists as in portainer or shipyard - you can google it) which would completely communicate with docker via the API. I personally haven't used it yet, I just used the command line. - The Docker Engine is pretty much the software itself. So if people say "Docker" they usually talk about the "Docker Engine". You can find more here: docs.docker.com/machine/overview/#whats-the-difference-between-docker-engine-and-docker-machine

[@atanudebnath9173]

Hi Jonny, Hope you are doing good. Thanks for giving a brief explanation for this part. I have just started with docker but I like this because of it's lightweight feature and its minimal utilization of resources. and building of own image. But if you could help me to learn about dockerfile. and its parameter ..like how to define. It will will be very helpful. I will be looking forward for your reply.. Thanks again for you precious time Jonny..

[@JonnyLangefeld]

As of my lack of time right now, I would just link to the official reference. I hope that helps docs.docker.com/engine/reference/builder/

[@atanudebnath9173]

Thanks Jonny....

[@dheerajmuttreja]

Thanks Jonny a lot ; it was so well explained . Good one

[@aty154]

Amazing tutorial, Good work. Its helps me to understand Docker better way.

[@yashasvibajpai4702]

nice tutorial! crisp one for utter beginners!

[@BrianTX541]

Very good tutorial. Thanks for putting this together.

[@packetjet]

Thank you very much - very helpful and respectful of my time. Perfect

[@markwilcock6460]

Fantastic presentation. Very helpful. Thanks Jonny

[@bondsboy]

Well done. Thanks for sharing this intro to docker will help me get started right away.

[@lokeshjaliminche]

Great tutorial!! Very easy to understand.

[@MrVelyx]

Not an english native speaker but i could understand you and therefor the topic really well. thank you

[@ivanabregu1]

Amazing explanation and easy to understand. Thanks a lot Jonny!

[@Valldak]

You're great! Very useful tutorial. Should have way more likes!

[@alexanderrende8544]

Jonny, is it possible to make a docker of NOD32 for linux using their linux installer. So that i can installed NOD32 on my nas to scan a nas folder for viruses. Thank you.

[@xmarkspot]

Cheers mate, this video was just what I was looking for!

[@zernelguan8144]

Much more clear now, thanks Jonny!

[@jk0000079]

What's the point of running a command with sudo, if you already are root?

[@choppertuber2858]

Hello sir , I need to dockerize my own lumen app . How can I do that ? do I need Ubuntu base image or php image ?

[@JonnyLangefeld]

I haven't worked with lumen yet, but in general I would recommend to browse through hub.docker.com/ and pick an image that has most of the stuff you need. And then you can customize your own image by starting with the FROM keyword in your own Dockerfile.

[@MrIslam8787]

Thank you Jonny, great tutorial. Learned new stuff.

[@MohammedBakheet]

That was awesome Jonny,, much appreciated :)

[@JonnyLangefeld]

Glad you enjoyed it

[@denisov1985]

Great tutorial. Thanks Jonny!

[@rohitdongre6034]

Thanks jonny for such a wonderful explanation. Your video is much helpful understanding docker basics. Thanks Much.

[@Ald0branti]

Hi thank you for giving me this startup but I have a real problem taking it any further RUN apt-get update && apt-get upgrade && apt-get install -y python3 The apt environment is in a mess and I get stacks of error messages like the following I have tried disabling lots of authenticayon checks but no win "At least one invalid signature was encountered. or "The repository 'ports.ubuntu.com/ubuntu-ports focal-updates InRelease' is not signed or "Release file for ports.ubuntu.com/ubuntu-ports/dists/focal-updates/InRelease is not valid yet (invalid for another 18645d 13h 35min 44s). Updates for this repository will not be applied. so the date in the image is 1970 , what to do to make the container start up with a clean value of the date here in 2021?

[@brunoseys6705]

nothing but quality here !

[@ecco256]

You do a great job at explaining, thanks!

[@Play_Streams]

This is an awesome tutorial. Thanks Jonny!

[@JonnyLangefeld]

Thanks for the feedback, you are welcome :)

[@rohitnair3903]

The tutorial was awsome...Will you please clear my confusion regarding deployment of a microservice.Do we have to practice the same approach of hosting it in IIS or on docker we have to host it

[@murilodemeloreis8210]

Hey John, I loved it, very helpful for beginers. I've searched you LinkedIn and found you, but you don't use it though.

[@tianlan6196]

Thanks Jonny for the tutorial. But I need to point out a misunderstanding @ 14:42. Docker is indeed building a new image instead of container every time when you execute "RUN" command.

[@JonnyLangefeld]

Oh, maybe I misunderstood that myself, however it doesn't really change the way you interact with it. But thanks for pointing it out!

[@dejo095]

@9:54 that command doesnt work on ubuntu, rm doesnt recognize switches -a and -q

[@user-cd5sg1kn6y]

You can't use that in your Ubuntu container unless you have another instance of Docker. That command is for the host that has Docker installed - i.e. MacOS.

[@RedManJin]

Fine explanation thanks a lot! but If I create a dockerfile containing python3 like in your last example I get this Error The command '/bin/sh -c apt-get upgrade && apt-get install -y python3' returned a non-zero code: 100 do you have any idea what happend?

[@JonnyLangefeld]

I don't know exactly what the error is, but the /bin/sh -c command looks weird to me. Try this in your Dockerfile, this definitely works for me: FROM ubuntu:16.04 RUN apt-get update && apt-get -y upgrade && apt-get install -y python3 python3-pip

[@sdolo222]

Thanks mate, I learned heaps from ya :)

[@ulkonja]

Does anybody knows how to enable the intel VT-x technology on a mac pro 2008. I need to run dockers from my mac pro but apple have disabled the vt-x by default. And even the updated efi from apple support doesn't work. Help!!

[@veenatapaswi2774]

awesome tutorial and neat explanation... thanku so much

[@pta03996]

Do you have a tutorial to set up a terminal like that in your video?

[@JonnyLangefeld]

Glad you asked, just uploaded one yesterday. Comments like yours inspired me to make it 😊 kzbin.info/www/bejne/amnJnoh9eK6dmZI Thank you!

[@Kishorekumar-ql6gl]

Could you solve my problem. How to pass docker container to our team members. So that they can use particular container. With out disturbing the other containers ?

[@nickimarie378]

Git Hub

[@kirkpennock2997]

So it is like a virtual machine, but smaller?

[@malharjajoo7393]

Great tutorial. Definitely helped me understand Docker , at least to some extent ...

[@nitishk1373]

superb explanation , keep it up buddy

[@amandaalves6897]

I'm using windows 7 and docker toolbox and can't create directories, my access is denied. Can you help me, please?

[@gccabraham]

Excellent Video. Thanks Dude.

[@ddamyanov]

Excellent overview and explanation!

[@karraygargouri3280]

Great Tutorial! it clarify many things about Docker! by the way, I would like to ask you: which software/program did you use to prepare this video (I mean to separate 2 windows: one for the code and the other for you)? Thx!

[@ngoacmieng]

Thanks for the awesome video, it's really helpful.

[@sarahbeecroft2864]

Nice video! thanks!

[@julesnzietchueng6671]

This is pure awesomeness, thank you!

[@willswill8163]

Amazing. All I needed to get started!

[@nurulsyuhadah3051]

Hi johnny, Does the step that you share can be used for window docker installation?

[@venkysunkesula4513]

One of the best tutorial

[@race512]

Around minute 10 when you want to start a container locally you already have the path created but, obviously, when i try to pull it it shows me an error cause this path doesnt exist. Should i create it manually? or should it already exist cause all the images are already there?

[@race512]

Besically, i understand that every local folder is different, but where do I find where my local folder is?

[@richardwang3438]

nice tutorial, thanks jonny

[@AshishBhatt25]

Hi Jonny ! Can you please point me to the dot files you are using?

[@COSMOPOLITANWORLD]

Hey, thanks for your tutorial! :)

[@DBAaron]

I like the video but 1,5 minutes in you say that "data" is not persistent inside a container. This is not entirely correct as you can start and stop containers (e.g. mysql) and inside that database the data you manipulate is persistent unless you delete the container. Correct me if I misunderstood what you've said! Cheers

[@ahmedtitan3598]

Great video. Thanks for you effort.

[@sudarshannagaraj6986]

great stuff for Docker beginner. Can I run an image created on a particular OS on any other OS ? Say when I create an image on Windows, Can I run it on Ubuntu Linux ? Thanks

[@insaneviruss]

Thanks for the video. Excellent for kick starting Docker! One unrelated question... What is your $PS1 value ? It's quite awesome and productive. Can you please share ?

[@JonnyLangefeld]

The link for my entire command line setup is in the description ;) my $PS1 value these days is the following, but I switched it up a little since I made this tutorial. But still mainly the same: $(print_icon MULTILINE_FIRST_PROMPT_PREFIX)%f%b%k$(build_left_prompt) $(print_icon MULTILINE_LAST_PROMPT_PREFIX)

[@victorychang1294]

Excellent tutorial. Thanks.
