LAMP on Docker

How to use

Available in the docker registry under castawaylabs/lamp-docker

Manual build:

1. docker build -t CastawayLabs/lamp-docker git://github.com/CastawayLabs/lamp-docker.git

Usage:

1. Make directories for your website files. We use the following setup:

• mkdir -p /home/websites/domain.com
• chmod 750 /home/websites
• chown root:root /home/websites
• Nginx routing host:80 to a port opened by docker (see below)

2. Run the docker image

• If you have a mysql instance running, and want to link it to the container, see section below.
• docker run -d --name "domain.com" --hostname "domain.com" -p 8080:80 -v /home/websites/domain.com:/var/www CastawayLabs/lamp-docker

3. There is no step 3. See below for additional configuration

Linking MySQL

Run a mysql instance, make sure to name it 'mysql' or similar.

docker run -d --name "domain.com" \
	-p 8080:80 \
	-v /home/websites/domain.com:/var/www \
	--link mysql:db \
	-e "DB_USER={MYSQL_USER}" \
	-e "DB_PASS={MYSQL_PASSWORD}" \
	-e "DB_NAME={MYSQL_DB_NAME}" \
	CastawayLabs/lamp-docker

In your PHP script, access those variables using:

$db_name = getenv('DB_NAME');
$db_pass = getenv('DB_PASS');
$db_user = getenv('DB_USER');
$db_host = getenv('DB_PORT_3306_TCP_ADDR');

Sending Email

This image is configured to relay mail through mandrill. (contribute to add other mail relays).

Add the following environment variables when starting the image:

• [email protected]:myAPIPasswordGeneratedFromMandrillapp.com

Logging

An interesting topic with docker, we've solved it by sending the log files to papertrail. Setting a hostname will ensure you know which log container to look at when required, and not having to dig around with docker cp etc.

Set this environment variable to enable logging:

• RSYSLOG=*.* @logs2.papertrailapp.com:12345

Tips and tricks

• Export log files from docker: docker cp domain.com:/var/log domain.com_logs
• Look for messages at boot for diagnostics. It will say something about mandrill if its enabled, and something about RSYSLOG when you enable logging.
