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!

@CoentraDZ 2 года назад

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

@francksgenlecroyant 2 года назад

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!

@johnshaff Год назад

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 !

@infinite_sorrow 4 месяца назад

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

@donalslemon4947 3 месяца назад

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.

@yossisternlicht21 2 года назад

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.

@michakwiatek5031 Год назад

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.

@michalnalevanko6608 2 года назад

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.

@CarlosVixil 10 месяцев назад

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

@MuhsinAslan 2 года назад

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

@springmemory6637 10 месяцев назад

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

@VFXTutorials 10 месяцев назад

Great tutorial!

@NetNinja 10 месяцев назад

Thanks!

@DependerKumarSoni 10 месяцев назад

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?

@keifer7813 7 месяцев назад

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

@reynold99991 2 года назад

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

@202prince1 Год назад

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

@stevesun1530 2 года назад

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

@MrKaspi097 2 года назад

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 2 года назад

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.

@TariqSajid 2 года назад

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

@alexanderpoplawski577 2 года назад

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!

@barcactu1032 Месяц назад

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

@akaharrison1644 Месяц назад

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
