Migration from drupal 7 to drupal 8
0 likes61 views
The document discusses using Docker and Docker Compose to set up a development environment for migrating a Drupal 7 site to Drupal 8. It describes creating Dockerfiles for Drupal 7 and 8, a docker-compose file to define linked PHP and MySQL containers, and configuring volumes to allow the Drupal 8 container access to files from Drupal 7. This allowed running Drupal 7 and 8 side-by-side for migration testing and the ability to crawl the Drupal 7 site from Drupal 8.
Migration from drupal 7 to drupal 8
- 1. Migration from Drupal 7 to Drupal 8 Chris Ozog ...how Docker can save our lives!
- 2. Hello! I am Chris Ozog I am here because some people think that I love PHP and Drupal?! You can find me at /krzysztofozog
- 3. Few words about me... A Philosopher and A Developer… the worst thing is that I have two master degree diplomas More the developer than the philosopher: ❖ For more than decade I’m building Web Applications ❖ In 2004 I built my first App in PHP ❖ I’m addicted to clean code ❖ I’m Chief Technology Officer at Codesushi ❖ I love code review...
- 4. Agenda ❖ Short intro to docker and docker-compose ❖ Our migration process in general ❖ What we used docker for ❖ Our setup in details ❖ Summary
- 5. about:docker ❖ Container management software ❖ Container “is a lightweight, stand-alone, executable package of a piece of software that includes everything needed to run it” ❖ Benefits of Docker ➢ Easy to use ➢ Quite easy to learn * (if you get the concept, it’s not a VM) ➢ Prebuilt containers with services like MySQL, PHP, Apache etc.
- 6. about:docker-compose ❖ Started as Fig, then development had been taken over by docker team ❖ Tool that helps with orchestrating multi-container environments ❖ Makes using docker super easy ❖ Makes a great tool for sharing development environment ❖ It uses YAML file as configuration
- 7. Our migration process We needed to migrate content from D7 to D8, we tried different migration processes and end up with need of writing one. ❖ Need of having D7 and D8 instances side by side ❖ D8 instance needed to have file access to files directory of D7 ❖ D8 also needed to crawl D7 instance - so it needed to be alive ❖ We also needed to run it couple times daily, because of development process
- 8. What we used docker for ❖ Development and testing environment - that resembles actual setup ❖ 2 separate Drupal PHP (with apache, php, composer and drush) containers for PHP 5.6 and PHP 7 ❖ 2 separate MySQL containers ❖ Volumes configured so D8 can access D7 file uploads
- 9. Docker setup in detail ❖ Dockerfile for D8 ❖ Dockerfile for D7 ❖ Docker-compose.yml ❖ Directory layout ❖ https://github.com/codesushi/kiev-drupal-docker

- 15. Couple of screens: D8 install
- 16. Couple of screens: D7 install
- 17. Couple of screens: D8 Calls D7
- 18. Summary ❖ Docker is fun - especially with docker-compose ❖ Two php versions is no problem ❖ Create complex setup with docker-compose with ease ❖ Testing load balancer approach ❖ Drupal and docker get along well
