To run the commands inside the container you use RUNcommand which sole purpose to execute commands within a container. RUN php composer-setup.php -install-dir=. RUN php -r "copy('', 'composer-setup.php') " RUN docker-php-ext-install pdo pdo_mysql mysqli I am also going to make changes in Dockerfile FROM php:7.3-apache It means that in order to run this service (PHP), MySQL service must be up. Also notice the depends_on under websitesection. By setting restart:always means that whenever the container goes up, MySQL will also be started. The default 3306 port is mapped to 8082 port.
#Php apache docker password
You may remove MYSQL_USER and MYSQL_PASSWORD section but you gotta set the root password then for sure. Here you see that envrionmentsection contains parameters related to connecting with MySQL server. Development/PetProjects/DockerPHPTutorial/src:/var/www/html The docker-compose.yml will now look like this: version: '2'Ĭommand: -default-authentication-plugin=mysql_native_password Docker compose is not doing something different, as I told earlier. It will take a while if the required image does not exist. Worked well, now it’s time to execute the docker-compose up command to build and create the images(If they don’t exist already) and create containers. For that you will run docker-compose config command which should show something like below OK, the file is ready, before you actually execute it, let’s check whether all is well in it. If you already have built the image separately then you may ignore this part but since the objective is to use a single file to manage everything then it’s good to opt for it. In this is it is in the current directory. It is actually to look for the Dockerfile. Under the build you will find context section. The image section is timilar to set the tag in docker run command. Under the website section I set container_name which is obviously for setting the name of the container. Just do remember that this name will be used to communicate with other containers. You may dedicate it your friend or sweetheart, doesn’t make any difference. Since I will be making websites in PHP so I just named it as website. The services section will contain the list of all the tools/services you are intended to run. Right now version 3 is available but since I have an old installation so I stick with it. The very first line is about the version of docker compose itself. Development/PetProjects/DockerPHPTutorial/src:/var/www/html/ Let’s create a simple docker compose file that will be doing the same thing that we did in the previous post. Mine output is docker-compose version 1.23.1, build b02f1306. You can check the docker compose version by running the command docker-compose -version on command line. Without further ado, let’s start creating our docker-compose.yml file. Just like you create a Dockerfile to define how your image look like, in docker-compose.yml file you can the mention the image(s) you want to use as well as the parameters of run and docker build commands. You can consider Compose a batch file that contains a set of instructions, commands to perform operation. Using command line based tools like docker build and docker run could be tedious in real-world scenarios where you have to run multiple containers.
#Php apache docker how to
In the last post you learned how to install the docker itself and create a Dockerfile. In this post, we will be building a full-fledged PHP application that will be communicating with MySQL. In the first part I discussed how to install and configure Docker for PHP based application.
