Kreativrudel Docker Compose Launcher

This small script initializes an docker-compose environment.

Installation

Just run the init.sh script from this repo in your project root directory:

bash <(curl -s https://raw.githubusercontent.com/micron/docker-setup/master/init.sh)

If you're lazy like me I suggest that you create an alias for this command:

alias docker-init="bash <(curl -s https://raw.githubusercontent.com/micron/docker-setup/master/init.sh)"

When all is done you'll have the following files and folders in your project directory:

├── docker                          # holds the configurations files
│   ├── run-mysql-dump.sh           # mysql dump script
│   ├── reset-wp-user.sh            # Tries to reset the WP user using WP-Cli
│   ├── dumps                       # imports everything with an .sql or .sql.gz suffix into the database on initial startup
│   ├── lib                         # mysql /var/lib/mysql directory for data persistance
│   │   └── mysql
│   ├── nginx                       # nginx webserver configuration
│   │   └── default.conf
│   └── supervisord                 # can be ignored
│       ├── start-socat.sh
│       └── supervisord-socat.conf
└── docker-compose.yml              # actual docker compose file

In action

To bootup the containers just run docker-compose up. If you want to daemonize just append the -d option. Depending on your database import file (if present) it could take a while until the mysql container will become available.

To restart the containers run docker-compose restart. To shutdown all containers run docker-compose stop.

Accessing your application

The application listens on your localhost on port 8088. When everything worked you should see you application under http://localhost:8088.

Logging

To read the logs from an running container just type docker logs -f application_wordpress_1.

Loggin in php the php container

To read the whole log stream from a php container you can do the following:

docker logs -f application_php_1

To display only errors in the stream:

docker logs -f application_php_1 >/dev/null

To display only the access log in the stream:

docker logs -f application_php_1 2>/dev/null

Source

Debugging

Our php images come always bundled with xdebug. Unfortunately you need to make a modification in the nginx config under docker/nginx/default.conf. Alter the IP in the following line: fastcgi_param REMOTE_ADDR "192.168.63.26";. After the modification you need to restart the container.

Since the port 9000 is already taken by the php-fpm service you have to listen on port 9001 for incoming xdebug connections.

Testing

This docker-compose setup comes with an selenium container. It listens on port 4444 on your local machine. You can also connect to the container with a vnc-viewer client

Database

Create a snapshot

If you want to create a snapshot from the current application database cd into the docker directory and run ./run-mysql-dump.sh. This should automatically pick the right database. If that is not the case you can overwrite the input by typing in something else.

WARNING The destination file in the dumps directory will be overriden.

Reset the admin user

If you want to reset the admin password change to the ./docker/ directory and run ./reset-wp-user.sh. This resets the password of the selected user to asdf1234.
