Docker WordPress Dev Environment

This post documents setting up local development environments with Docker using the official WordPress Docker repository as a base image. Page two includes configurations for remote PHP debugging with Xdebug and VS Code.

Docker Compose

Aside from making the container configuration easier to understand, Docker Compose coordinates the creation, start and stop of the containers used together in the environment.

The environment has multiple sites served on various ports including at least one WordPress site, a phpmyadmin site and mysql. For virtual host names, nginx-proxy is being used for containers with virtual host environment properties set in their docker compose data. Additionally, the mysql db container is accessible from the host at 127.0.0.1:8001

Create this docker compose yaml file in the projects root directory with the nginx-proxy configuration.

nginx-proxy.yml
version: "2"
services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    ports:
      - "80:80"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro

Create this docker compose yaml file for the WordPress stack. This includes the linked MariaDB database and phpMyAdmin containers from their official repositories. Xdebug is not included in the official WordPress image on Docker Hub and will not be included in this configuration since it is using unmodified images. Adding xdebug and rebuilding the image is covered on page two.

wp.yml
version: "2"
services:
  db:
    image: mariadb
    volumes:
      - mysql:/var/lib/mysql
    ports:
      - "8001:3306"
    environment:
      - MYSQL_ROOT_PASSWORD=secret
  phpmyadmin:
    image: phpmyadmin/phpmyadmin:latest
    ports:
      - "8002:80"
    links:
      - db:mysql
    environment:
      - MYSQL_ROOT_PASSWORD=secret
      - VIRTUAL_HOST=phpmyadmin.app
      - VIRTUAL_PORT=8002
  wp:
    image: wordpress
    volumes:
      - ./wordpress:/var/www/html
    ports:
      - "8003:80"
    links:
      - db:mysql
    environment:
      - WORDPRESS_DB_PASSWORD=secret
      - VIRTUAL_HOST=wordpress.dev
      - VIRTUAL_PORT=8003
volumes:
  mysql:

Update your systems hosts file.

hosts
# Docker (nginx-proxy)
127.0.0.1 phpmyadmin.app
127.0.0.1 wordpress.dev

Navigate to your project root in your CLI, such as Terminal on OS X, PowersShell or Cygwin on Windows.

Create the Containers

Create new nginx-proxy and WordPress containers using the up command with docker-compose.

docker-compose -f nginx-proxy.yml -f wp.yml up
  • The -f flags specify the compose files to use. Multiple compose files are combined into a single configuration. This multiple file solution is for demonstration purposes. Here is a single file example that can be run without a file flag.

Stop Containers

Stop the containers without removing them.

docker-compose -f wp.yml -f nginx-proxy.yml stop

Start Containers

Start the stopped containers. Include the nginx-proxy.yml first so when the WordPress containers are started the virtual hosts can be dynamically configured.

docker-compose -f nginx-proxy.yml -f wp.yml -f start
  • If you have restarted your computer and another process is using the nginx-proxy port, e.g., 80, you will need to halt that process before starting the container.

Shutdown Containers

Shutdown the environment using the down command. If your data is not stored in a volume, it will not persist since this will remove the containers.

docker-compose -f wp.yml -f nginx-proxy.yml down

The next page covers adding Xdebug and configuring VS Code for remote debugging.


vue-devtools Chrome Extension in Firefox

When I wrote this post in March, only a Chrome vue-devtools extension was available. Using the Chrome Store Foxified add-on, this post documents installing the vue-devtools Chrome extension into Firefox for debugging Vue.js applications. However, as of June 20, an official Firefox Addon is available.

Vue.js (@vuejs) tweeted at 1:22 AM on Tue, Jun 20, 2017:
vue-devtools is now officially available as a Firefox Addon
DevTools extension for debugging Vue.js applications

Installation

I’m using the Firefox Developer Edition for this install. It should also work with Firefox and Aurora (Firefox Developer Edition) for Android.

Install the Chrome Store Foxified add-on. The Mozilla WebExtensions cross-browser API supports a growing number of Chrome extensions and this add-on facilitates installing them in Firefox.

You will need to be signed into addons.mozilla.org/firefox with your Firefox account to install the add-on normally. Search for vue-devtools at the Chrome Web Store.

Select the Add to Firefox button.

In the Vue.js devtools dialog, Select Just Sign and Download.

Foxified - Vue.js devtools sign and download dialog. The Google Chrome extension has been fetched and converted into Firefox  format. Would you like to install the addon normally or temporarily?

Another Vue.js devtools dialog appears after the add-on is processed. select Save Signed Addon To File.

Foxified - Vue.js devtools sign and download dialog. All process complete. Choose from any of the actions below. Note: WebExtensions API is not yet complete by Mozilla so all extensions may not work yet.

Navigate to the Firefox Add-ons manager, about:addons and
select Extensions from the sidebar.

Add-ons Manager

Open the Tools for all add-ons dropdown gear next to the search all ad-ons input. Select Install Add-on From File. Browse for the .xpi file that was downloaded.

Add-ons Manager - Tools for all add-ons

Restart Firefox to begin using the vue-devtools.

Javascript Frameworks

After discovering yet another interesting Javascript framework for the web application development recently (Vue.js), I decided to put together this short list of some the emerging and more popular frameworks out there today for building user interfaces.

Emerging

Mithril is a light-weight robust MVC framework with no dependencies, a small API and small learning curve. Mithril implements a virtual DOM tree similar to React.js, however Mithril’s uncompiled templates run natively in the browser and compile into static Javascript data structures. Mithril.js was initially released in March, 2014 by Leo Horie. Source available at https://github.com/lhorie/mithril.

AngularJS v2: Angular.io

At ng-conf 2015 last month it was announced that AngularJS 1.X will continue to reside at angularjs.org and Angular 2.0 will be hosted at angular.io. The new version of Angular is not a major update, it is a complete rewrite. In February, Brad Green announced that Angular 2 was officially Alpha in this First look at App Development in Angular2 video.

During the ng-conf 2015 keynote, Brad and Igor talked about some of the big work that is being done on Angular 1 is work that will be shared in Angular 2, including:

  • New Router that focuses on mobile and large complex apps.
  • New Internationalization (i18n) module
  • Better Performance

Compass on Windows

This post documents my latest compass install on Windows which should be simple enough. I ran into a minor issue and was getting an error:

$ gem install compass
ERROR:  Error installing compass:
        The 'ffi' native gem requires installed build tools.

How to install the build tools

Go to the same place that has the RubyInstaller for Windows, http://rubyinstaller.org and select Downloads. Download the Development Kit (build tools) that corresponds with your version of Ruby. If you need to install Ruby (required), it is recommended that you use the Ruby 1.9.3 installers. I noticed that a newer version of the Ruby 1.9.3 installers were available, might as well get the updates. To summarize, here are the two packages I downloaded for my Windows 8.1 machine:

Install or update Ruby using the Ruby 1.9.3-p550 RubyInstallers before installing the DevKit. Check your installed version as follows:

C:\>ruby --version
ruby 1.9.3p550 (2014-10-27) [i386-mingw32]

Important – during Ruby Setup, make sure “Add Ruby executables to your PATH.” is selected:

Setup - RubyInstallers
Setup – Ruby 1.9.3

After extracting the DevKit to C:\RubyDevKit, run these these commands:

C:\RubyDevKit>devkitvars.bat
Adding the DevKit to PATH...

C:\RubyDevKit>ruby dk.rb init
[INFO] found RubyInstaller v1.9.3 at C:/Ruby193

Initialization complete! Please review and modify the auto-generated
'config.yml' file to ensure it contains the root directories to all
of the installed Rubies you want enhanced by the DevKit.

C:\RubyDevKit>ruby dk.rb install
[INFO] Updating convenience notice gem override for 'C:/Ruby193'

DotNetNuke 7 Module Templates


I wanted to stick with the environment setup I have been using which is a host name of dnn7 or dnndev. Working in IIS and modifying my host file is not an issue for me. If you are looking for a way to create a new module directly within the DotNetNuke CMS environment, you could give this extension a try: DNN Module Creator.

Download Source Code for Christoc’s DotNetNuke Module Development Template at
http://christoctemplate.codeplex.com/

This post is based on the DotNetNuke 7 Project Templates V2.0 for VS2012, Thu Jan 24, 2013. Newer 2.x versions of this template project may have somewhat different node or node block keys in the csproj files for the environment variables we are modifying in this guide. The premise is still the same and this information should be enough to help make the changes as needed.

You will need this to modify and rebuild the source: Microsoft Visual Studio 2012 SDK http://www.microsoft.com/en-us/download/details.aspx?id=30668

Windows 8 Shortcut Keys

I installed Windows 8 on my 2009 SONY VAIO FW series laptop today. Here are a few keyboard shortcuts I found useful.

  • Windows Key + C – Charms
  • Windows Key + D – Desktop
  • Windows Key + F – Search Files
  • Windows Key + I – Settings
  • Windows Key + K – Devices
  • Windows Key + P – Projector options
  • Windows Key + Q – Search Applications
  • Windows Key + R – Run
  • Windows Key + X – Administrator tools
  • Windows Key + Enter – Narrator

Smart Snap

  • Windows Key + Right or Left Arrow
    Moves the open window to the left or right half of the screen.

Additionally, if you are on the metro screen, and there is not a search input shown, just start typing and one will appear with your query. Tapping the Windows key will cycle you through open screens as well. The ever faithful Alt + F4 (close) and Alt + Tab (cycle windows/apps) shortcuts are indispensable… Ctrl + Tab is handy as well.

Improved Font Rendering in Fedora 15 / Gnome 3

  1. Checkout this blog article at infinality.net: Subpixel Hinting and Other Enhancements for Freetype & Fedora 15 RPM Packages
  2. Per the infinality article, install the infinality-settings package
  3. Edit /etc/X11/.Xresources to read:
    Xft.autohint: 0
    Xft.lcdfilter:  lcddefault
    Xft.hintstyle:  hintfull
    Xft.hinting: 1
    Xft.antialias: 1
    Xft.dpi: 96
    Xft.rgba: rgb
  4. Install Windows fonts. To do this, I copied all the .ttf fonts from my mounted Windows 7 device (/mnt/ntfs/Windows/Fonts) to /usr/share/fonts.

C# String Utils

Documenting a few simple string utils I created for an app recently

Be sure to resolve usings as needed

public static string SingleSpace(string str)

	//replaces multiple spaces with one.
	RegexOptions options = RegexOptions.None;
	Regex regex = new Regex(@"[ ]{2,}", options);
	str = regex.Replace(str, @" ");
	return str;
}

public static string SlashFlip(string source, int direction)
{
	string returnVal = null;
	if (direction == 0) //back
	{
		returnVal = source.Replace(@"/", @"\");
	}
	else if (direction == 1) //forward
	{
		returnVal = source.Replace(@"\", @"/");
	}
	return returnVal;
}

public static string SlashTrim(string str)
{
	if (str.IndexOf(@"/") == 0 || str.IndexOf(@"\") == 0) //first char
	{
		str = str.Substring(1, str.Length - 1);
	}
	if (str.IndexOf(@"/") == str.Length || str.IndexOf(@"\") == str.Length) //last char
	{
		str = str.Substring(str.Length, 1);
	}
	return str;
}

public static string IdXml(string[] idArray)
{
	string returnXml = null;
	List ids = new List(); //list of id's for the XmlSerializer
	foreach (string id in idArray)
	{
		ids.Add(Convert.ToInt64(id));
	}
	//create Xml doc from list to pass id's into sproc as a single param
	XmlSerializer xs = new XmlSerializer(typeof(List));
	MemoryStream ms = new MemoryStream();
	xs.Serialize(ms, ids);
	returnXml = UTF8Encoding.UTF8.GetString(ms.ToArray());

	return returnXml;
}

public static string StripDomain(string userIdentityName)
{
	//remove domain name and back slash if present
	int i = userIdentityName.IndexOf(@"\");
	if (i > -1) userIdentityName = userIdentityName.Remove(0, i + 1);
	return userIdentityName;
}
