2 years later still so useful.

This is the most clear explanation I ever seen at KZread for Docker. All other videos I watched before in other channels they just explain like they are robots.

The greatest explanation about Dockerfile. I was typing things in this file just for the sake of typing because i saw it working in a tutorial, but from now on, i know what each and every single layer mean. Thanks Shaun!

I love your Docker series. Your teaching style is clear, straight to the point, and very methodical. Thanks for the time and efforts you've put into this. Really appreciate it!

You have your dependencies installed after the source code in your example docker file. Docker caches layers, and by installing dependencies before copying the source code, you can leverage this cache mechanism. If the dependencies don't change often, Docker can reuse the cached layer with the installed dependencies, which speeds up the build process. By installing dependencies after copying the source code, the cache will be invalidated whenever your source code changes, even if the dependencies remain the same. This leads to longer build times.

thank you so much for this mr shaun ! you really helped me with my work. i really cannot understand docker for a long time but you explain it so simple and clean ! Thank you, keep it up mr Shaun !

This was exactly what I needed, thank you and well done. Clearly explained, with specific elucidation of the command usage and meanings. I'll be checking out the rest of the videos in this series as I still have questions around the 'AS base' and 'AS build' modifiers as well as how 'ENTRYPOINT' works.

finally someone that takes the time to actually explain the syntax while they go along.......the structure of the language is critical in order to learn, yet so few actually tell you what you are doing, they just tell you enter this blah de blah enter that yada yada. Thanks man i was going crazy trying to find something that gave me a clue lol

I'm so grateful for people like you in the KZread! I just needed to review the Docker's main concepts and this series is helping a lot! Thank you!

I wish this video played anytime anyone ever mentioned docker. then it wouldn't be so mysterious and overwhelming.

Hey ninja, you all right? your breath is a little sick. Thank you for docker playlist :)

well done

Great tutorial as usual. One point, what will happen if we change package.json to reference a new dependency, will the previous version get installed from the cache? This could be a big issue.

thanks for the free presentation. BUT .. often recomended - and only where it is possible: I would appreciate a much larger, more noticeable, maybe colored pointer/cursor, moved with a calm hand to allow me following more easily your brilliant thoughts.

Great tutorial!

Please create a k8s series as well i love you style of teaching

WORKDIR - specifies where the commands should run RUN commands are run at image build time. This means commands that we want to actually be executed on runtime should be added in CMD

I think the order of commands should be different to speed up rebuilding image. I would first copy packages.json into /app, then run npm instal, and finally copy the rest of the app files. Thanks to that approach, after modifying something in app files, reinstall of npm packages won't be necessary. Small caveat: It requires to set up volume to be able to develop our app locally without need for rebuilding.

Awesome tutorials ++++++++++++++++++++++++++++ Thank you.

Great explanatiion

In laravel there is a package by names of laravel sail that will write the docker-compose file automatically for the project. hope u make some tutorials about laravel too

You're welcome!

👌👌👌👌

You said, every line after "WORKDIR: /app" would run in /app directory. Then while executing the COPY statement, would not it take source as /app. Which means, copy all from /app to /app?

May I ask? Shouldnt we use the first parameter of command COPY with 2 dots to specify root directory where all the files are stored? As our working directory is /app already.

9:00 Does WORKDIR create an "app" folder if it doesnt already exist? Since you said image file structure is completely different to a project's file strcuture

Nice one as always.A little confusion though where are your node_modules from express js installation

he deleted it on purpose to run node_modules with docker

With the port number is this standard for docker or can it be assigned any number?

How i am loving and appreciating this can't be containerized

does the github link always default to the main repository with readme file in the youtube videodescription or is it possible to change it to the other repositories like lesson 5 which contain the files shown in video

You need to change the branch to access respective lesson files. Like change the branch from main to lesson-5 for lesson 5 files.

didnt see api file on the links, can you show me where is it?

what about file permission in docker ? how to create user inside docker for logs permissions

All commands during image build and in the container are executed as root. Since the base image is a linux system, you can run commands to add a user and switch to that user in subsequent commands in the Dockerfile. I am pretty sure all this will be explained in more detail during the course. Be patient!

Where do i open the lesson 5 at? Help, i'm a Dummy

What if I need to install global package from that node version at specific version and use it in cmd? Eg I need cordova@10 (11 is latest) and use 'cordova build' command? What if I change sth in code? Do I need tk build it again? I'm guessing yes, asking to be sure.

@alexanderpoplawski577

Just add a RUN npm install -g cordova@10 to the Dockerfile. After that you can add RUN cordova build. Yes, if you change something in the Dockerfile or the content, that goes into the image you have to build again. There is an alternative with volumes, but I think Shawn will address this in the following parts.

I waited for app directory in the tree... but it has been stored in the other dimension xd

Where's the source file? I can't find it without paying.

I did not understand how can you COPY . . And get the /api content into /app

@akaharrison1644

In my own understanding is that, he create a dockerfile in same directory with dependencies and app.js, that's why he runs the command COPY . . which the first "." represent the relative directory that all of them are located then the second "." is telling the command to save everything in the "WORKDIR /app" created

Please the simple node project isn't in github.

Isn't it a bit too fast for beginners?!

takes so much time on RUN npm install after 397 seconds it fails
