Docker + Wodby + Docksal technology and comparison

This is my introductory talk on Docker that I gave on 1st Drupal Serbia meetup in Niš-

https://www.meetup.com/top-lista-drupalista/events/238489719/

The story about the docker is just too complex to be covered up with a single 40 minute talk, so I gave an overview on virtualization technologies and how is the docker positioned there.

Included in presentation, I showed practically how easy it is to start a container once the docker application is installed.

It enables both Windows and Mac to have seamless development integration of PHP, web server and database but also Linux would benefit from isolation of environments for different projects.

Get the docker here: https://www.docker.com/

Once installed, check Drupal quick start with this docker-compose.yml https://github.com/wodby/docker4drupal

More complex but powerful Drupal containers with Docksal (still experimental with native docker) with this docker-compose.yml https://github.com/docksal/docksal/

Both are multicontainer and require some understanding and familiarity with terminal. But both are powerful tools for every developer.

If you wish to discuss matters with me, you may wait for another live presentation or catch me somewhere online, I'm easy to find and always in a good mood for a discussion on any matter.

4. MLADEN ĐURIĆ a.k.a MacMladen • in IT since the time of mainframes, 8th year in UNIX epoch (that’s 1978). • started with Z80 assembly, went over 6502 to 8086 (1978-1990) • somewhere in between, there was an episode with BASIC but really enjoyed hard core C • was knee deep in DTP 1990-2000 • gone to Mac in 1995 and never looked back • 2005 started playing with web technologies • 2007 landed on Drupal :D 4 TopListaDrupalista Niš 2017

18. INSTALLATION 18 TopListaDrupalista Niš 2017 Docker Engine is supported on Cloud, Linux, Windows and Mac OS. wget -qO- https://get.docker.com/ | sh docker –version Docker is treated like other services. sudo service docker status
 sudo service docker start Test the installation using this code sudo docker run ubuntu:14.04 /bin/echo 'Hello world'
19. https://hub.docker.com/ 19 TopListaDrupalista Niš 2017
20. docker command 20 TopListaDrupalista Niš 2017 sudo docker run -d -p 8080:80 --name apache --link mysql:mysql -v /var/www/html:/var/www/html jessecascio/ local:apache # verify the two containers are running, and link exists sudo docker ps sudo docker inspect -f "{{ .HostConfig.Links }}" apache
21. Dockerfile 21 TopListaDrupalista Niš 2017 The Apache Dockerfile build configuration file can look like this: FROM ubuntu:14.04 RUN apt-get update RUN apt-get install -y apache2 RUN apt-get install -y php5 php5-common php5-cli php5-mysql php5-curl EXPOSE 80 CMD ["/usr/sbin/apache2ctl", "-D", "FOREGROUND"]
22. docker-compose command 22 TopListaDrupalista Niš 2017 version: "2"

 The Drupal docker-compose.yml may looks like this:
23. 23 TopListaDrupalista Niš 2017 docker and docker-compose commands docker controls individual containers by name or ID while docker-compose controls a group of containers, usually called application or stack. Usual Docker commands: docker ps -a — lists all docker containers, running, paused and stopped. docker inspect mcidev_nginx_1 — lists all details about the container by name or ID docker stats --no-stream — shows resource usage, omit --no-stream to have live stats docker-compose up -d — while in directory structure containing docker-compose.yml, creates and starts application. docker-compose pull — fetch latest version of containers. docker-compose stop — stops application docker-compose start — starts application docker-compose restart — restarts application docker-compose down — remove containers (instance of contaners images)
