I never comment on things, but you seriously gave me an exact explaination as I needed so I just wanted to tell you that I'm super thankful. Continue working man. Be determined. Great guide
Whoever gave a thumbs down really doesn’t care about docker. Great tutorial as I am learning this at work. Really helped me grasp what we were doing. Thanks!
Brilliant tutorial Ryan, thanks so much. You take a unique approach of intentionally showing errors and then fixing them. This is how we learn in the real world: from our mistakes. I "liked, subscribe, and hit that bell." The first time ever!
@The Simple Engineer: I am curious about the fact of Caching. Node is interpreter and npm installs dependencies but does not builds an binaries. So for caching it worked... Like here in this case I already have package.json imaged and Express also imaged. So I used cache. I only copied the index file.. But then question comes, if this has been a Java app that compiles and build Binaries, then in this case a change in Java file needs to be compiled at application level. So In that case I have to copy fill Application files ( except resources ) and then run build ( e.g. by maven ). In this case I suppose the cache will not be very applicable! right?
Where can I find the rest of the docker series as mentioned at the end of the video? Finding these first few videos extremely helpful, but then it just seemed to end at this video.
Hi, One small doubt. What is difference between "RUN" & "CMD" in Dockerfile ? Seems like both are executing commands. Then, why "CMD" needs to be passed as ["npm", "start"] ? Please clarify.
RUN executes command(s) in a new layer and creates a new image. E.g., it is often used for installing software packages. CMD sets default command and/or parameters, which can be overwritten from command line when docker container runs.
Have a pretty intense project that includes use of Polymer, Firebase, LitElement, Webpack, etc. Tried to use the node image and mapped the ports correctly but for some reason when I go to localhost, there's nothing available? I see the project building successfully in the terminal after I run docker run ... but unable to access the project online? Any advice?
Thanks for the tutorial, learned a lot. I had to increase youtube play speed to 1.5 though... If its not too much trouble for the next viedo, could you speed up talking next time?
This is seriously one of the best videos on docker I’ve ever seen

This is the best explanation on youtube about Dockerfiles. Thanks.

i guess Im kinda randomly asking but does anyone know a good place to stream newly released movies online ?
@Sean Peter Flixportal
@Darren Jayce Thank you, signed up and it seems like they got a lot of movies there =) I really appreciate it!
@Sean Peter You are welcome xD
whoever gave this a thumbs down is a moron of the highest caliber
Best docker course ever. Thanks

4:54 "getting an error was intentional" -- brilliant! Why don't so many tutorial creators understand this?
Simple and elegant explanation
Really like the way you are explaining... kudossss to you👍
Really excellent tutorial. I loved they way you planned it out, and progressively demonstrated features as needed.
Great video with crystal clear explanation
You are so good at explaining things. Thank you so much.
Simply wonderful brother... thanks a million, definitely you learnt well and you teaching well too
Great video, can you do one on kubernetes if you get a chance?
Excellent introduction, Thank you. I realize the world is changing, like some cosmic spirit is uplifting the whole world, getting faster and faster...
Best videos I've watched on Docker! Thanks.
This video is amazing. Very well done. Thank you
Great video, really easy for me to understand (and others have tried, trust me). Thank you!
great video and explaination, thank you so much.
Sir, thanks for the tutorial, please make more videos in general, you explain well.
Excellent tutorial! Thank you very much for the quality content. Keep it up!
Fantastic and very productive.
Very well explained...
Thank you so much for an excellent video
Fantastic video. Thankyou so much,

Glad you liked it!
Great video

Excellent.
dope video. finally actually understand it.
Really great tutorial, thank you for sharing.
Thank you very much.
Thanks a lot for the tutorial! Will there be a next part?
Perfect tutorial.

Check the server logs from within the docker container. Sounds like a a server or application level issue from within the container.
Why the dog in the background is shocked, did you put him in a container ?
😂
Great Stuff,
Thanks!
Thanks for this video you made very simple!
by the way your audio is super nice, would you mind to share your gear/setup ?
Thanks!
Panasonic G7, Blue Yeti Microphone and MacBook pro 2016 15inch. Post processed in audition for the audio

your amazing dude thanks alot for this great video
Where these docker images are stored ? In host machine ? Which path ?
Locally on host once they're pulled from remote registry. Type docker images to list them
waiting for the next part
👍👌
thank you
I had to use IP 0.0.0.0 in the app to map to localhost, how come it works for you not for me?
What a strategy,
Try something,
if it succeeds -> all good
if it fails -> claim it was an intentional error
Repeat
Intentinal errors are great at demonstrating the debugging process, and are usually more helpful than "golden path" tutorials
Finally, a coherent Docker guide without an Indian accent.
Good explanation. But unfortunately the title gives a diff meaning. You are using parent image and not base image.
Thanks for the tutorial, learned a lot.
I had to increase youtube play speed to 1.5 though...
