Using Docker For Local Development

WordPress Site

The app docker image starts a running WordPress site with the local wp-graphql-acf directory installed and activated. Local changes to the source code is immediately reflects in the app.

  1. Build the plugin. 1.1 composer install or docker run -v $PWD:/app composer --ignore-platform-reqs install
  2. Run composer build-app to build the app docker image.
  3. Run composer build-test to build the testing docker image.
  4. Run composer run-app to start the WordPress site.
  5. Browse to http://localhost:8091/ to access the running WordPress app.
  6. Browse to http://localhost:8091/wp-admin/ to access the admin dashboard. Username is 'admin'. Password is 'password'.

Testing Suite

The testing docker image starts a running WordPress and runs the codeception test suites.

  1. Run composer build-test to build the testing docker image.
  2. Run composer run-test to start the testing image and run the codeception tests.

Using XDebug

Local WordPress Site With XDebug

Use an environment variable USING_XDEBUG to start the docker image and WordPress with xdebug configured to use port 9003 to communicated with your IDE.

export USING_XDEBUG=1
composer run-app

Start the debugger in your IDE. Set breakpoints.

Load the app in http://localhost:8091/.

Using XDebug With Tests

Use the environment variable USING_XDEBUG to run tests with xdebug configured to use port 9003 to communicated with your IDE.

export USING_XDEBUG=1
composer run-test

Start the debugger in your IDE. Set breakpoints.

Configure VSCode IDE Launch File

Create or add the following configuration to your .vscode/launch.json in the root directory. Restart VSCode. Start the debug listener before running the app or testing images.

If you have WordPress core files in a directory for local development, you can add the location to the pathMappings for debug step through.

{
    "version": "0.2.0",
    "configurations": [
		{
			"name": "Listen for Xdebug",
			"type": "php",
			"request": "launch",
			"port": 9003,
			"xdebugSettings": {
				"max_children": 128,
				"max_data": 1024,
				"max_depth": 3,
				"show_hidden": 1
			},
			"pathMappings": {
				"/var/www/html/wp-content/plugins/wp-graphql-acf": "${workspaceFolder}",
				"/var/www/html/wp-content/plugins/wp-graphql": "${workspaceFolder}../wp-graphql",
				"/var/www/html": "${workspaceFolder}/wordpress",
