Images

• build the image within the image folder docker build -t <tag-name> .

• php-fpm exposed on the port 9000.
• Run /usr/sbin/php5-fpm --nodaemonize as the entrypoint.

Containers

• start a container: docker run [-it] [-d] [--rm] [-p <host-port>:<container-port>] [-v <host-volume:container-volume>] [-l <container-name>:<var-name>] --name <container-name> <tag-name> [cmd]
• run a command on a running container docker exec <container-name> <cmd>
• start nginx linked with php-fpm with docker-compose (in app folder): docker-compose up nginx-php
• start nginx linked with php-fpm (in app folder):

docker run -d --name php-fpm -v $(pwd)/html:/var/www/html demo/php-fpm:latest
