Create a drupal development environment using docker.

Currently at work i am using docker to streamline and speedup of development and deployment to testing and production, I am using symfony currently and our app is dockerised, i wanted to do the same for drupal based apps.

I searched for a official drupal docker repo and i did find this. https://www.drupal.org/node/2538074

Unfortunately there was very terse explanation but pretty much worked, i found a few hiccups along the way so wanted to share what i did.

Pre-requisite:
Install docker for your environment. Lots of details are available at https://docs.docker.com/ explaing docker and installing docker for your environment.

The docker repo holds the drupal container at https://hub.docker.com/_/drupal/, following the instructions this is how to create the drupal container:

In order to use my code base we need to mount the volume with the -v directive as below, we do this in one command:

docker run -v /$HOME/work/drupal8:/var/www/html -p 8080:80 --name mydrupal -d drupal

this will create a drupal container using drupal code in your home folder, this brought up a new site however soon i had a problem where


Because i was using my local folders mapped to /var/www/html i need to ensure the sites/default/files are writable, normally you should be careful what permissions you should set, more information is on drupal site. for now 777 will do, so i did a chmod 777 $HOME/work/drupal8/sites/default and also created a settings.php as instructed. Also chmod 777 $HOME/work/drupal8/sites/default/files.

Now comes the database part, at this point i created another container with mysql, fortunately a official mysql repo is also available on hub.docker.com

docker run --name mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -p 3307:3306 -d mysql:5.7

giving the command above download the mysql 5.7 image, set the root password, expose the mysql port in the container externally, now our drupal app can use this container. normally you would store the data outside the mysql container, the repo page of mysql on the docker hub discusses that, for demonstration purpose it is just fine to have out data inside.

i also connected to this database container using sequelPro and created a new database to use and named it drupal8, then continued with the installation.

Unfortunately then drupal died, with the following error:



I can again gave permissions, but ended again with another permission issue. Thank God i am using docker...so i dropped the drupal container and decided to mount modules and themes folder seperately, and use drupal core inside the container.

So first i drop the container as below:

docker rm -f mydrupal

so my modified docker run now becomes:

docker run -v /$HOME/work/drupal8/modules:/var/www/html/modules -v /$HOME/work/drupal8/themes:/var/www/html/themes -p 8080:80 --name mydrupal -d drupal

Notice the use of -v to use external folders for modules & themes otherwise use the drupal codebase inside the drupal container.

now reinstalling again. I had to drop the database and recreate a blank database and finish the install.

Somethings to remember, us the docker machine IP address, which you get by running docker-machine env default, use this IP address in the database config as well as the browser to look at your new drupal site!


All Done!

Use feeds module to import XML data in Drupal 7

Recently i had to setup a xml import process to import data from an external supplier on a regular basis, the filename and format was not changing and i could choose where to store the file. Following is how i set it up.

First we need to download the following modules

feeds
feeds admin ui
feeds_xpathparser
ctools
job_scheduler

enable the above modules.

We will need a sample XML so this will be the one we will use for this demonstration:

<?xml version="1.0" encoding="utf-8" ?>
<!-- Sample for demonstration of processing XML feeds with feeds module -->
<Orders>
<Order>
<CustomerID>10</CustomerID>
<Order_Number>1</Order_Number>
<Order_Total>100</Order_Total>
<Currency>£</Currency>
</Order>
<Order>
<CustomerID>11</CustomerID>
<Order_Number>2</Order_Number>
<Order_Total>40</Order_Total>
<Currency>$</Currency>
</Order>
</Orders>


How do you expose your legacy database tables to views in drupal 6 Part 1

This is a 2 part post, that shows how I exposed a legacy table to views in drupal and used the incredible power of views to create many combinations static and conditional views. This was very helpful for my client.

I had a requirement that warranted exposing existing database table to views, so that views can contain data from this table.  To enable this to happen, the following steps need to be taken.
In a custom module you need to first define the views_api hook as following:
function candidate_views_api(){ $view = array(); $view = array('api' => 2, 'path' => drupal_get_path('module','candidate'). '/views'); return$view; }
candidate module was a custom module which I already had, so it made sense to add this hook here. 
The important bit here is telling the drupal sub-system where the views file will reside. 
Then create a file with your <modulename>.views.inc in my case it was candidate.views.inc, this file should have two hooks, one …
