• docker >= 1.10.0
  • wget -qO- https://get.docker.com/ | sh
• docker-compose >= 1.6.1

To run a project go to /src directory and run:

docker-compose up or docker-compose up --build to rebuild containers (docker caches layers).

A folder /ext contains extended images that require built base images, for example php lamp/images/ext/php5.6-apache/Dockerfile is based on php:5.6-apache base image (FROM clause). Because the image is placed in ofiicial hub it will be downloaded automatically, otherwise it should be build manually, for example:
docker build -t php-custom:5.6-apache --force-rm=true .
in a folder with Dockerfile inside.

Docker is a daemon, make sure it's running:

sudo service docker start

Tuned Ubuntu image:

sudo docker pull phusion/baseimage

Get containers IPs:

docker inspect {hash or service names} | grep IPAddress

Access to host 172.16.42.1 or 172.16.240.1 in case of subnet: 172.16.240.0.

Go to container's shell, or execute a command inside container:

docker exec -it 580b9e371f71 bash
docker exec {container-name} php -v

To exec a command as root for non-root service:

docker-compose exec -u root service_name bash

Run in the background:

docker-compose up -d
docker-compose logs

List of containers:

docker ps
docker ps -a - to see stopped containers.

Build and remove previous builds

docker build -t php:5.4-apache --force-rm=true .

Docker-gc: docker run --rm -v /var/run/docker.sock:/var/run/docker.sock -v /etc:/etc:ro spotify/docker-gc

RM all containers:

docker rmi -f $(docker images | grep "^<none>" | awk "{print $3}")f

Stop\rm all containers:

docker stop $(docker ps -a -q)
docker rm $(docker ps -a -q)

To show all ENV variables run:

docker-compose run db env

, where the "db" is a docker-compose.yml service.

To run the same services with a specific project name (by default dir name):

docker-compose -f /var/www/docker/lamp/src/docker-compose.yml -p test up
docker-compose run web db -d

To stop and remove containers with their networks:

docker-compose down Or

docker-compose stop
docker-compose rm -f
docker-compose network rm {service_name}

Remove all containers: docker rm docker ps --no-trunc -aq``

Run container: docker run -it {container} /bin/bash docker-compose run {service} /bin/bash

Monitoring.

Inside a container if you get "Error opening terminal: unknown." error exec:

export TERM=xterm

Rebuild a service with overridden one:

docker-compose -f docker-compose.yml -f docker-compose.fpm.yml build sugar-base-web-php

push, pull and tag methods can be executed via docker command, the rest methods are supported by HTTP API.
curl -X GET http://registry/v2/_catalog to retrieve a list of repositories in the registry.

For example you want to add PHP 7.0 image to the registry based on official image.

First make a new Dockerfile to fill the image with custom stuff:

FROM php:7.0-apache # Official image, see https://hub.docker.com/_/php/

# Tune it
# Install modules
RUN apt-get update && apt-get install -y \
        libfreetype6-dev \
        libjpeg62-turbo-dev \
        libmcrypt-dev \
        libpng12-dev

RUN docker-php-ext-install mysqli pdo pdo_mysql

# ...

EXPOSE 80
CMD ["apache2-foreground"]

In the directory run docker build -t php-custom:7.0-apache --force-rm=true .

Run docke images and make sure the new image exist.

REPOSITORY               TAG                 IMAGE ID            CREATED             SIZE
php-custom               7.0-apache          8bab3dfe689c        14 seconds ago      563.6 MB

Tag the image to change its repository name:

docker tag 8bab3dfe689c registry./username/php:7.0-apache

Note: This command does not affect the original image, just makes a copy with new repository name.

Now push the image to registry:

docker push registry/username/php:7.0-apache

Check the new tag in registry: curl -X GET http://registry/v2/username/php/tags/list

Lets add a virtual host to the image created in the Adding image.

Make a container from the image by docker run registry/username/php:7.0-apache or docker-compose up.

docker ps to make sure that container is running.

CONTAINER ID  IMAGE                                                   COMMAND               CREATED        STATUS        PORTS 
93046674cb61  registry/username/php:7.0-apache  "apache2-foreground"  3 seconds ago  Up 2 seconds  0.0.0.0:8081->80/

Copy a file with virtual host to the container

docker cp sites-enabled/000-default.conf 93046674cb61:/etc/apache2/sites-enabled/000-default.conf

Commit the changes:

docker commit -m "Added virtual host." -a "User <email@ex.com>" 93046674cb61 registry/username/php:7.0-apache

Push the image:

docker push registry/username/php:7.0-apache
