Manual usage of Docker Stack

(All examples on this page assume that you are using Linux/Mac OS and have cloned Docker-Stack to your user home directory. The commands should be executed in a Terminal window as your own user, not root or sudo.)

Run phpinfo() with PHP 7.4 as https://my-first.localhost

This scenario demonstrates:

• The function of the src folder.
• How to start containers without the helper scripts.
• The stacks support for '.localhost' domains.

---

# Make sure we're in the right place.
cd ~/docker-stack

# Create the folder ./src/my-first.localhost/pub
mkdir -p ./src/my-first.localhost/pub

# Create index.php
echo -e "<?php\nphpinfo();" > ./src/my-first.localhost/pub/index.php

# Start the containers you require.
./bin/docker-compose up -d nginx php74

You should now be able to access https://my-first.localhost (ignore errors about self-signed certificates, this is expected).

You should see details about PHP 7.4.

Change https://my-first.localhost to use PHP 8.1

This scenario demonstrates:

• Changing the PHP version of a host
• Manually refreshing/updating a container.
• Manually stopping a container.

---

• Edit the file ./docker/nginx/m-hosts.conf
• In the $PHP_HOSTM2 map, above the section marked "DEFAULT" add a new line. The line should say my-first.localhost php81;
• Update the Nginx container image: ./bin/docker-compose build nginx
• Update the running Nginx container to use the new image: ./bin/docker-compose up -d nginx
• Start the PHP 8.1 container: ./bin/docker-compose up -d php81

You should now be able to access https://my-first.localhost (ignore errors about self-signed certificates, this is expected).

You should see details about PHP 8.1.

(Optionally) You can now stop the PHP 7.4 container: ./bin/docker-compose stop php74
