This is an outstanding video. Some paid courses on Udemy are not as clear and helpful as this. You really get the idea that Gary wants you to understand what's happening, not just copy like a code monkey.
This is so great. You provide really thorough, detailed and clear explanations. And it is so refreshing to see modern PHP development being taken seriously. Thank you!
Thanks. I've watched umpteen videos on Docker but they all miss out, or fail to explain, key parts. Yours has finally made Docker understandable (ish!)
You really have the best teaching skills. I always had difficulty understanding the concept of construction (especially X-debug and Composer). Now I understand and I was able to apply it perfectly. Thanks!
Super helpful and helping the community and me a ton. Thank you so much. Literally saving my life. I've never used docker before and I just started in a development apprenticeship and could skip the first year but last time I coded anything was a few years ago and I never knew docker existed till recently through my boss wanting me to develop a app... using docker. So this is helping me out so much. Even if its nearly 2am
Awesome, to be honest for me It was a course of 3 days but with a lot of knowledge gained. Thanks for this video and as soon as possible the next course will be OOP. Regards form México :)
On 1:02 Hours of the course there is a command called "composer install". I do not have composer locally installed and I don't want to install locally on the MAC OS php and composer. Is there another way to get this up and running? Thanks a lot so far for this great tutorial.
This is such a great resource! I'm not even half way through but I love the pace and the content. Spot on dude! I've been working with DevOps for a few months now, and this seems like a great way to get the basics covered after diving head-in to multi-stage builds and Kubernetes deployments :)
Hi Gary, great content so far. My issue is that when I shell into my docker container my path is simply '/'. I've followed everything you've done and I still don't have var/www
Hi Gary, thanks for this video, it's just what I was looking for. A question: to install imagick adding "nstall-php-extensions imagick;" is enough ? Thanks
Yeah think that will be ok, it's on the list for mlocati/php-extension-installer Just check this list when you need to see if an extension is possible: github.com/mlocati/docker-php-extension-installer#supported-php-extensions
Wow! the video i was looking for. Absolutely awesome tutorials!! Gary can you also make a complete tutorial on making a php MVC framework from scratch, please. Cause this is also a undertought topic. You make easy to understand videos.
Hey Gary, would you dockerize an application before you actually start coding at all or is it an acceptable scenario to dockerize an app after you did some coding? I'm trying to dockerize a symfony application that I wrote but it seems that my code changes do not reflect on the container even though I'm using volumes. What do you think about this or what is the first thing that you would check up on in this regard? Thanks for the great content
It will always be easier to dockerize from the start but lots of applications get dockerized after a lot of code has been written. Most of the Symfony apps that I'm responsible for are dockerized.
Very nice video, thank you! It is really even better than the official quick course on Docker site (though the latter one is meant for dummies like me). I wanted to ask you, if you don't mind: I set up xdebug (not using your video, by using the guide from docker site), used "host.docker.internal" value, installed the same Chrome extension you are using in the tutorial, changed the IDE key in the extension to vsc (also tried another way - changing this parameter in VSCode settings), tried even adding port 9003 to ports section as "9003:9003" (though that does not seem necessary because I have not seen many tutorials mention this step) - but still xdebug is not working for me. I have Windows 10 22H2 in VMware, latest version of VSCode, PHP 8.3 and xdebug 3. What is most important, xdebug is working for me locally without Docker. Also, PHP Info page lists xdebug as enabled inside docker, so I guess it IS installed, but my IDE cannot receive the connection for some reason. My networking mode is "mirror host adapter", because it's the only way I can access my home Windows SMB share.
I've not done it in VSCode personally but give the XDebug playlist by @DerickRethansXdebug a go ua-cam.com/video/MmyxWy8jl7U/v-deo.html Loads of useful vids there. Derick created XDebug and he'll be happy to help you out.
Is necessary to keep volumes in web section for the production environment? .conf files are copied in nginx dockerfile so I think it's not but I preferred to ask.
Thank you Gary, I completed this super course entirely on an Apple Silicon. An immense value to me! It was so far the best course I've seen on the subject and the nicest thing, it's tailored exactly to my needs. Not too little, but not too much either. Just great! Please don't stop developing courses like this, I'm looking forward to the next one, maybe a detailed XDebug with all the subtleties for once?
Hallo Gary!. I am having a problem with the execution time of "imagecreationfromjpeg" (using php:8.1-fpm-alpine); it take minutes to do a jb that usually takes 100 milliseconds (create a jpg image from an url); I ried to install imagi in several ways but nothing change, so I am wondering if it could be a problem of php image. Have you any suggestion ? Many thanks in advance, Pierluigi
Yes..it could well be related to the php image. PHP and Docker have a history of performance issues but I don't know the solution to your problem off the top of my head. But my next steps would be chatgpt / google

Hi Gary, I am having toubles with a simple php curl call to get mime type of a public file. From inside the container it seems tha curl is unable to access the file, like it was unable to resolve the url address: $ch = curl_init(".....something....); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $curlExec = curl_exec($ch); $curlExec is FALSE.

My css and js files, loaded via a Link or Script tag, result in a 404.

@@GaryClarkeTech Thanks Gary for this solution, this does indeed work. I have now found the cause why it did not work before.

Amazing, thank you for this easy yet comprehensive tutorial. It helped me grasp certain concepts my brain refused to digest previously.
Great..I'm glad it worked for you!
...another great video by Gary. Looking forward to see Symfony (simple dev "quickstart" version) dockerized :)
At 36:07, what is the reason the port numbers need to be in quotes? I don't see how it is different to when you specified the Nginx port mapping.
You can do it with or without quotes...I usually use quotes just as a habit but I guess I'm not always consistent!
