With this video you managed to explain the abstract docker technology in a simple and understandable way. As far as I know you have presented more or less all the essential concepts of Docker. great presentation!
Been looking for something like this for AGES! Super clear explanation which worked & answers SO many questions I had trying to move from old-style-VM-dev to docker/docker-compose. Nice one!
Hello, Nevyan! I just wanted to thank you for your EXCELLENT tutorial. This video is exactly what I was looking for! I wanted to connect PHP with MySQL through Docker (using "docker-compose") because I'd decided to learn PHP but I didn't want to install it on my PC. Congrats!

Unfortunately, there is no any Docker's tutorial tells us what is next?! In other words, what can I do if I want to distribute, backing up or migrate these Docker's stacks to another machine. In that case, I have my code and the database data beside the environment, what can I do to make them run on any machine by simple command(s)?
Hi Said, you can use public or create private registry, and when ready with your images, containing your code you can push them to the registry, and use them from anywhere once you pass an authentication. For the databases you can create and link separate volumes(disk drives,folders, etc) to the container, residing on a specific machine or using cloud virtual machines, again accessible from anywhere. Anyway nice ideas for a new video :)
Great tutorial. How did you select the PHP tag at around 7:21? There are really a lot and don't make much sense to me. Thank you in advance for your help.
You can choose appropriate tag by clicking on the TAGS tab, there you will find different images offering variations of the php language such as: alpine, fpm, cli, apache. Each of them can be useful for specific development / production purposes. In the main php dockerhub page under section variants you can learn how they differ from each other.
It is good if you have another container running phpmyadmin. It has the benefit of not interfering with your other application container. This way you can scale the main application, without scaling the phpmyadmin (as if they were on the same container). Decoupling of application logic also allows when doing updates to update only the needed parts of the whole stack (like phpmyadmin) and its dependencies, not interfering with other container applications.
Great tutorial , it helps a lot!. But facing an error `Pulling db (myql:8.0.1)... ERROR: pull access denied for myql, repository does not exist or may require 'docker login': denied: requested access to the resource is denied ` while docker-compose up
sir, I have tried this on an ubuntu virtual machine in open stack. I got stuck after creating .yml file and using docker compose up. the terminal stops and doesn't show an image after this statement. command line: 'apache2 -D FOREGROUND' nothing happens after this.. what is the issue?
I'm not using the command you mentioned in the video, anyways the correct syntax would be: CMD ["apachectl", "-D", "FOREGROUND"] - this will run Apache in foreground, causing it not to respawn as new process with different PID, but to run inside the shell/init process(already running with PID 1). Docker follows the PID 1 exit signal in order to kill the container. In this case will follow apache, so the container will not exit until apache is not stopped.
Thank you, you can try the containerized version of phpmyadmin: hub.docker.com/r/phpmyadmin/phpmyadmin/ or please take a look at my comment to Yogi Ghorecha.
Hi Great Video, very useful. I'm using a virtual machine with ubuntu server, I can ping it and have acces to it via sftp on my local machine, but when I run the containers and try to acces from my browser i get a ERR_CONNECTION_TIMED_OUT. Care to give some advise?
Hi, I would first run nmap to see if there are any container ports open inside the VM. Then if there are would check on the host the same and would do ports redirect from the VM to the host if they aren't.

Hi, you have several options: 1) to use VSCode plugin for Docker to develop inside a container 2) to create a 'bind mount' and develop locally, while running the result in container environment. 3) when your code is ready to be deployed for production, to build and push a new image of your application to a 'registry'(local or remote) and then create and run a container based on the image.

Hi, please post the whole docker log in order to investigate. It is good to check if you are using volumes: whether inside the docker container already exists anything in the volume. Or, just try to clean up the whole system with: "docker system prune --all" and recreate the compose file services. Note: by default mysql uses user with uid=1001 (which is non-root), so it is also possible that you are trying to mount your local /var/lib/mysql (mysql data directory not owned by 1001), to a non-root docker image. This will fail, since user 1001 (from the container) needs to perform read/write operations to your local directory. In this case please do: sudo chown -R 1001 /tmp/mysql

Please check the credentials and port you are connecting to. Apart from this in your php code, you'll need to connect to host name which is the service name - in this case it is called: db.
@@NevyanNeykov whooa thank you for answering my question, sir. It's fixed by now. but may i know how the docker network can be formed? I mean how the network of form_default possibly happens? Thank you so much sir, this is very important for my study, you helped me so much
Docker compose shares a default subnet between its containers/services. Additionally one can specify different networks to be used by the containers. Internally, this is done via virtual network interfaces using the concept of namespaces.
@@NevyanNeykov oh i get it sir thank u so much. But what if, i want to make another pages with php? Should i make another services in docker compose or I only create a new container from php images and connect it to the network sir? Sorry if I'm asking too much anyway🙏
Container acts as an isolated server. From there on, you can create multiple containers each representing a service application/database/storage etc. on one or several distributed bare-metal machines, and connect them together.

You are right, you can have as many images as you want and they will not interfere. In the video we just had to rebuild the images, to reflect their new configuration. This could be done either with compose up (when there are no existing images the command will also build them) or with compose build.

@@til4dome4 I'll start by inspecting and creating the application requirements such as: persistent volumes, networks, environment variables etc. Then would try to convert the monolithic application into micro-services and will create connected containers, where those micro-services would interract. When done, before going live, would increase the container security by using non-root users, exposing only needed services to the end-user, as well as placing additional resource monitoring containers. All this orchestrated by Kubernetes.
I agree, personally prefer stand-alone dev server to create experiments on bare-metal machine. Nowadays Docker becomes obsolete, being replaced with Podman, and so on...

plz if you will to put the repo of project for all files used in this tutorial or use gist github is very powerful for this typical case. thank you a lot.
thank you for the advice, it is a nice idea.
I think you make a typo and used php 7.3 on compose and 7.3.3. on docker file, but it doesn't matter it only used the Dockerfile one
Hi, it is not a typo. First in the docker-compose we create a simple php web service, based on php:7.3-apache. Then we update the web service using custom Dockerfile, which helps us to add MySQL extensions, it is based on another image: php:7.3.3-apache.
thank you very much
I am glad, that you like the video !
Perfect!!!
Thank you :)
Still getting 403 forbidden even after creating index.php would someone help me with solution please?
Just execute shell to enter inside the container and inspect as it is your own machine.
i get this error when i run docker-compose up in 08:06 :

Hello sir thank you for your grateful tutorial, i have some trouble in connecting the php and db like this: Warning: mysqli_connect(): (HY000/2002): and its look like because of the $host name. Can you figure it out sir? Thank u so much anyway
Please check the credentials and port you are connecting to. Apart from this in your php code, you'll need to connect to host name which is the service name - in this case it is called: db.
@@NevyanNeykov whooa thank you for answering my question, sir. It's fixed by now. but may i know how the docker network can be formed? I mean how the network of form_default possibly happens? Thank you so much sir, this is very important for my study, you helped me so much
Docker compose shares a default subnet between its containers/services. Additionally one can specify different networks to be used by the containers. Internally, this is done via virtual network interfaces using the concept of namespaces.
@@NevyanNeykov oh i get it sir thank u so much. But what if, i want to make another pages with php? Should i make another services in docker compose or I only create a new container from php images and connect it to the network sir? Sorry if I'm asking too much anyway🙏
Container acts as an isolated server. From there on, you can create multiple containers each representing a service application/database/storage etc. on one or several distributed bare-metal machines, and connect them together.
My cli doesn't recognize "nano" command. what's the name of the CLI please
You can install it using: sudo apt install nano. Or just use another text editor.
so the /php folder acts as a /var/www/html/ folder ?
yes, this will be the document root folder residing inside the container, for serving php files.

Hi, please check your spaces and indentation - docker syntax is sensitive.
@@NevyanNeykov Do i have to create the directory /var/www/html , before running the docker compose
/var/www/html is a directory which will be automatically created inside the container.
Thanks for the help.. i was able to build it. now im trying to add a data(from my local machine) which has an extension of .sql(10 gb data) into mysql database in docker. can you please help me with that. i appreciate the help. thank you

@@NevyanNeykov thank you. I m a layman in this thing. can you break this down into smaller steps and can you explain me?
thank you
@@ranaarepalli if you already have the sql file, please see the reply to Andres Henao's comment, where you import your local database dump file into the mysql container using proper credentials.

other than this continue to debug line by line..
why would other images interfere? isn't the idea of containers to isolate environments?
You are right, you can have as many images as you want and they will not interfere. In the video we just had to rebuild the images, to reflect their new configuration. This could be done either with compose up (when there are no existing images the command will also build them) or with compose build.
my question is where's your files folder?
which files ?
Hi friend. I have a problem. When I try to run index.php you get this message.
Warning: mysqli :: __ construct (): (HY000 / 1045): Access denied for user 'devuser'@'172.18.0.3' (using password: YES) in /var/www/html/index.php on line 7

hi, try to remove the line: command: --default-authentication-plugin=mysql_native_password and rebuild the container with docker-compose up -build
other than this, please check your credentials for connection to the mysql(db) container service.
@@NevyanNeykov delete the command line and it remains the same. How do I verify or change the credentials. It seems more like a permission problem. But I don't understand what it can be. To msql it connects fine
In de docker log say sha256_password reported: ''sha256_password' is deprecated and will be removed in a future release. Please use caching_sha2_password instead
such description of a problem sounds very mixed to me... Probably it is your php file - the connection string, check the host/username/password combination you are using, whether it exists in the mysql USER table, and if not please add it.
@@NevyanNeykov phpmyadmin now works fine. This is my mistake now Warning: mysqli::__construct(): The server requested authentication method unknown to the client [caching_sha2_password] in /var/www/html/index.php on line 7. Thanks
if in your setup phpmyadmin works, you can take a look at its source files on how it makes the connection and use the same in your index.php file.
plis help me with you source code + docker action workflow code plis🙏
what exactly are you looking for?
@@NevyanNeykov i haven't solved the problem, my teacher asked me to push docker hub and push github
@@NevyanNeykov and the case you have is similar to me, maybe you know how to push to docker hub and github?
why not do it in virtual machine with vagrant? you do it in your local computer.
Because of speed decrease when being in virtual environment. Otherwise the setup is the same.
@@NevyanNeykov thanks, yes but I don't like "dirt" my machine, so I think is better make it a virtual machine, of that way you can update or delete the MacOS without loosing the docker stuff.
@@JohnSmith-zl8rz like with the VM's you can always remove the containter and its contents. Biggest container plus is that you don't need to install an additional OS, thus the container becomes a lightweight, and much faster wrapper of your app.
:( "You don't have permission to access this resource."
Try using sudo in front of the command, or just use chmod to change the permissions.

What if i have a web application already and would want to incorporate docker, how would i go about it? Kindly help
@@til4dome4 I'll start by inspecting and creating the application requirements such as: persistent volumes, networks, environment variables etc. Then would try to convert the monolithic application into micro-services and will create connected containers, where those micro-services would interract. When done, before going live, would increase the container security by using non-root users, exposing only needed services to the end-user, as well as placing additional resource monitoring containers. All this orchestrated by Kubernetes.
@@NevyanNeykov Thank you so so much...let me work on it, then will get back to you
As a dev for many years , they have made a simple process of setting up a webserver way too complicated. Ridiculous
I agree, personally prefer stand-alone dev server to create experiments on bare-metal machine. Nowadays Docker becomes obsolete, being replaced with Podman, and so on...
@@NevyanNeykov Nevertheless i forgot to tell you that you did a great job of doing the vid. Much Appreciated. You simplified it over alot of others that I watched
