#Docker #DevOps
Docker is the de facto standard for building, shipping and running applications in a consistent manner. That's why most companies use it and are looking for developers with Docker skills. If you're looking for a career in software or DevOps engineering, you must have Docker on your resume. And not only that, you should know it well and be able to use it to effectively package and deploy your applications.

Just starting my coding journey and found your website and courses by accident. Couldn't be more thankful for what you have put together. You're such a gifted teacher! Learning SO much thanks to you!! :)
did you get the zip file?
@@edwinchiboko3737 yah dude where is the zip file
thank you!! where is the zip file you mantion in 5:54?
I really enjoy and appreciate all your work, you make the world better with your courses where you combine all necessary knowledge and tools for programming. I really love programming and, for sure, you made me love it! Peace and Love from Ukraine!❤️
Did you find the zip file?!!
You're the frickin' BEST teacher here, Mosh! Man, if I become a IT teacher one day, I hope I can be like you! You explain everything so clearly, you seem to understand what people need to get something. That comparision you did beetween json and yaml what GOD TIER.
I bought you Redux course and IT WORTH EVERY CENT!
How can you find the code?

thank you Mosh for your high quality and amazing tutorials. wish you the best.
I only appreciate your lectures after going through the ones done by others. This guy is a genius teacher.

I couldn't be more thankful for what you do!
Superb Mosh-jan. Thank you. I say this without prejudice. Content is fluid, it stops to point out significant landmarks without cluttering, and therefore the duration is also tolerable in this age of millisecond attention spans. I learned a lot and refreshed a lot.

Where is that bloody zip file?
how can I get the ZIP file?
where is zip? can you please link?
You're a life saver Mosh, this is just what I was looking for💯
did you get the zip file
You are AMAMAMAMAZING Mosh.. God Bless you for the free stuff!
I like your tuts very much dude. Simple but practical
If you are wondering why the version number is string, it's because version can be something like 3.8.1 which is not a number.
at 5:50 you mentioned the zip, there is not zip file link in the video description.
This video cleared my doubts, love the content.
You are the best teacher ever you explain once and I allredy understand.😄😄
Really appreciate your content Mosh!
It would be great if you could make a course on Devops tools ( Open source tools ) with the CI /CD Pipeline.
Thank you so much for this wonderful tutorial
Thank you Mosh, you always make good tutorial!
Congrats ! The course is awsome ! Thank you :)
Regarding JSON vs YAML: It's not only about performance, but also about validation and security.
If you, e.g. copy+move some lines from a JSON file to another location, most likely, the JSON will be corrupt and incorrect, and if not, it's very likely, the order didn't matter anywhere. That's good behaviour for anything that mainly computers operate, as such a copy+paste error easily happens while editing (or merging with git), but might not be reviewed by (many) humans, so might be undetected for a long time. In YAML, there is a good chance, randomly moving blocks around, the end result is a different, but still correct YAML. Indeed, that's such a common error, that for bigger projects you usually have to write an own linter for the yaml files checking e.g. if the keys are the expected ones. Regarding security: YAML specification is a bit bigger than XML, so it contains a lot of hard to implement and possible insecure options. That's why many first naive implementation of YAML parsers in programming languages were replaced over time by other parser only implementing a secure subset of YAML. (Or alternatively that's tackled by the custom linters you have to write anyway)
There are some other subtle problems with YAML, e.g. your question of why you have to put "3.8" in quotes is because otherwise it would be detected as float und depending of whether can be represented in binary internally exactly or only close to it (indeed, 3.8f == 3.7999999523162841796875). The easiest way to enforce consistency is to demand that the version is always a string and not sometimes a string (3.8.0 == "3.8.0"), sometimes a float (3.8 == 3.7999999523162841796875) and sometimes an int (4 == 4).
There are many more subtle possibilities to misinterpret the unquoted strings: Magic words like true or false are becoming booleans. A minus sign is very often interpreted as list start, several further characters like +, |, also have special meanings and so on. When in doubt, always put your strings into quotes, from a practical standpoint that the system should what we want to say in the yaml, even though readability is reduced.
That's why, where high predictability is wanted, often enough different formats are used with less surprisings. E.g. HCL for Terraform, Programming languages for Pulumi, AWS CDK, ... or just toml/ini files.
Anyway, the high readability, easy understanding and universal structure of YAML dominates pretty much every modern stack, so the solution to all the above problems are custom linters and performant YAML parsers (most often with an own subset or dialect).
BTW, JSONs have disappointing also ambiguities that can even be exploited, e.g. the spec does not tell anything what should happen if a key is duplicated (which value to take). Different parsers handle that differently, and for the right combination, you can pass the validation done by the first parser to then inject some malicious (or just unintended, unwanted) behaviour to the second parser.
Thanks for the info man
Thank You Mosh! I'm gonna take your course!
Mosh we are so glad to see you're back
Really great videos , well explained , just awesome !
Thank You Mosh. This tutorial was great!
so proud of You Mosh ! I'm from Iran , Hamedan too. !!
Hello Mosh! Thank you for making these amazing tutorials. Could you please link the zip file that you are referring to in this video so that we can follow along? Thank you!
thanks Mosh. as always, great tutorial.
thank you so much for shaing your knowledge in an intersting way
I really enjoy ur videos with great understanding, I want to be a software developer but I don't know which programming language to learn first, and where to start 😶
good stuff. thank you. now the world needs your take on svelte!
what a great content! so grateful to you
Thank you for this tutorial, I was having problems until I saw your video thank you very much
This was really helpful. Thank you.
I hope you will continue and thank you very much
you are my teacher
Finally the legend is back 😎
Thank you! Please support me by liking and sharing this video. :)
Learning is a continuous process
Absolutely mosh!..
Done :-)
@@programmingwithmosh Hello Sir! How can I Unsubscribe Code with Mosh? I've Completed My courses. Thanks a Lot!
Happy to see you brother!! Love from India 😍
I learned so much from your 6 hours python course .Thank you so much Mosh🙏
Great explained. Thank you so much.
You're a Pro, Mosh! Thanks vm
Great tutorial , that helped me well
Thanks
Being a metalhead for decades. I just found my new favorite person and that guy's name is Mosh! \M/
Really really it's great to see u on live ❤️❤️
This was one hell of a great video. You have a great teaching style. You are VERY clear in your explanations. And best of all, your screen captures are MOBILE-FRIENDLY. This video was missing the 1 thing I came looking for, but I am glad I watched the whole thing. Liked. Subscribed. Will look over your courses and purchase any that are remotely relevant to my needs. ☮❤🌈
PS: What I needed was how to do a "reverse port map/access". That is, I need initiate "from contain to host", instead of the "from host to container" that is explained EVERYWHERE. I have since learned this is done via `docker run --add-host=host.docker.internal:host-gateway` or in docker-compose.yaml `extra_hosts: ["host.docker.internal:host-gateway"]` Then [for example] your container can access the CUPS printer on your host machine via port: 631 on host: host.docker.internal
Flutter tutorial please, we have all been waiting so long for that 😀👍
Thanks, very useful. Well done.
Great video, Thank you!
thank you mosh ...lovely !!
The reason version has to be in quotes for docker-compose is that yaml spec parses numbers such as 3.0 to 3 and it breaks versioning.
You're an excellent tutor.
super helpful, thanks!
Thanks for your excellent video!! Where I can download the files did you use in your examples?
Thanks for this tutorial!!!
You're the best mosh ❤️💙
This guy is thug, everything is easy in his world. Thanks so much for all the effort Moch!
I love your tutorials
I just want to let you know that your courses are top class.
One improvement I would like to see in your course is the project you develop during the lectures. Even though *Vidly* is really a good project, I would like to see much complex project than that. Maybe an e-commerce project. Point is: you have tons of cool techniques to improve the quality of code which we can learn from your experience.
Where can I find the Vidly zip file ?
Amazing tutorial! i'm so tired of just stackOverflow codes without explain, thanks so much!
my king mosh i love you so so much, you taught me how to be the best programmer big love from africa Ethiopia.
Thank you! Please support me by liking and sharing this video. :)
@@programmingwithmosh Where is the Zip file? 5:56 ????
Your are the best "mosh".. no one can beat you
Thank you! Please support me by liking and sharing this video. :)
Thank you for the explanation
Thanks for this wonderful tutorial.
I'm trying to follow however could not find the link to download the zip file.
Hi there I wanted to find out if you also do Cyber Security tutorials just started my course and your Python and Java tutorials have helped tremendously.
Hope to hear from you soon.
I was waiting for this ep. and enjoyed it!!!!! :DDDDD
But can you please make a c++ beginner tutorial?
hi moshi, long time , you the best man
Thanks for sharing, it was a useful video.
Hi mosh I was seeing that the code on python was not with the @client.event part and I’m very confused could you help me on what to do
what is the difference between docker-compose and docker compose.. I noticed that I'm getting an error when I use docker-compose but everything works well when I change it to docker compose .. without the dash
Great Video. I am new to docker compose. I tried the same steps as per your docker compose file but gut this error. nable to prepare context: path "./frontend" not found does VS Code follow indentation?
You are always awesome. Everybody loves you :)
Nice tutorial, thanks. It's full of valuable information.
👆send a direct message for support and guidance
Very Very Thank Your videos are very good.
Hi, what are your terminal configurations for the highlighted autocomplete? Thanks.
14:09 I think that could be to allow subversions like 3.8.2 etc which would not translate well as numbers.
Also, version is deprecated and ignored by docker. It's literally just a comment at this point. From Docker spec (emphasis in original): "A Compose implementation SHOULD NOT use this version to select an exact schema to validate the Compose file, but prefer the most recent schema at the time it has been designed."
what a great video !!!
Need more videos on docker Thanks!
Hello, I am not able to find the zip file with the app below the video. Could you help me, please?
Fantastic course
Love it, I’m being stuck for 2 weeks
Where is the Zip file? As stated in this video at 5:47...
Where's the ZIP file you were talking about attached belowed - i'm unable to find it
Finally Mosh ❤️❤️❤️
Are you sharing the code for this tutorial anywhere?
Great job 👍.
Helpful , thanks
Amazing tutorial
Great course and next that I hope you make course about Docker + Kubernetes. :)
Hey Mr Mosh.....thank you for everything you are doing?? I want to know how I can go about registering for your course and how much it costs
Great work and thanks again! I like that VS Code editor color scheme. What is that called?
Which theme did you use in vs code for HTML and CSS tutorial?
What vs code extensions and terminal do you use?
woww!! Thank you so much Mosh for such great content, I'm a 1st yr CSE college student in India and request you to please make a OOPs in c++/ python !!, I saw ur 7min video on OOPs and I really understood it very well
Please can you code for crypto arbitrage for different exchanges?
How is the experience at a programming college? I also want to go the path of coding (I'm indian).
I need the repo of the front end and back end projects so i can play sround with docker compose
Big fan of you 🔥
How can one determine what the needs of the project are for a docker compose file? How do you know what the requirements are?
im from iran and thanks for your very nice course
what's the name of the util that autocompletes what you write in your terminal? thanks
Thanks for sharing
Awesome thanks
