webspectyler / wp-cli-deploy Goto Github PK

April, 2016

It just so happened that in the last year, my development interests shifted away from WordPress. As such, I ended up not writing a single line of PHP in over twelve months.

I believe that the tools we build are best when we use them ourselves, and the reality is I don't use wp-cli-deploy anymore, so I decided to hand off maintenance of this project to someone else.

If you’re interested in the gig, ping me on Twitter and we can take it from there.

Current Version: 1.0.0 (stable), 1.1.0-beta (in dev)

Deploys the local WordPress database or uploads directory.

The tool requires defining a set of constants in your wp-config.php file. The constants should be prefixed with the environment handle which you will use as the first parameter for your desired subcommand. An example configuration for a "dev" environment:

<?php
define( 'DEV_URL', 'the-remote-website-url.com' );
define( 'DEV_WP_PATH', '/path/to/the/wp/dir/on/the/server' );
define( 'DEV_HOST', 'ssh_host' );
define( 'DEV_USER', 'ssh_user' );
define( 'DEV_PORT', '22' );
define( 'DEV_PATH', '/path/to/a/writable/dir/on/the/server' );
define( 'DEV_UPLOADS_PATH', '/path/to/the/remote/uploads/directory' );
define( 'DEV_THEMES_PATH', '/path/to/the/remote/themes/directory' );
define( 'DEV_PLUGINS_PATH', '/path/to/the/remote/plugins/directory' );
define( 'DEV_DB_HOST', 'the_remote_db_host' );
define( 'DEV_DB_NAME', 'the_remote_db_name' );
define( 'DEV_DB_USER', 'the_remote_db_user' );
define( 'DEV_DB_PASSWORD', 'the_remote_db_password' );
define( 'DEV_POST_HOOK', 'echo "something to be executed when the command finishes"' );

=> wp deploy push dev ...

Not all commands / subcommands require all constants to be defined. To test what a subcommand requires, execute it with a non-existing environment handle. e.g. wp deploy dump johndoe.

You can define as many constant groups as deployment enviroments you wish to have.

Examples

# Deploy the local db to the staging environment
wp deploy push staging --what=db

# Pull both the production database and uploads
wp deploy pull production --what=db && wp deploy pull production --what=uploads

# Pull both the production themes and plugins
wp deploy pull production --what=themes && wp deploy pull production --what=plugins

# Dump the local db with the siteurl replaced
wp deploy dump andrew

• Clone this repository in your WordPress directory.
• Create a wp-cli.yml file in the root of you WordPress directory with:

require: "relative/path/to/deploy.php"

• You can now use the deploy command. Type wp help deploy to see if it works.

• Clone this repository into your ~/.wp-cli/commands/ directory so that the path to deploy.php is:

~/.wp-cli/commands/deploy/deploy.php

• Edit your ~/.wp-cli/config.yml file to make sure it has the following:

apache_modules:
  - mod_rewrite
require:
  - "commands/deploy/deploy.php"

• You can now use the deploy command from any WordPress directory. Type wp help deploy to see if it works.

In order to be able to use the deploy command, you need to define certain constants in your wp-config.php file.

Subcommands depend on different constants in order to work. Here's the dependency list:

• wp deploy push: In order to push to your server, you need to define the ssh credentials, and a path to a writable directory on the server. These constants are needed whatever the arguments passed to the push subcommand:

  • %%ENV%%_USER
  • %%ENV%%_HOST
  • %%ENV%%_PATH

• wp deploy push %%env%% --what=db: In order to deploy the database to your server, you need to define the url of your WordPress website, the path to the WordPress code on your server, and the credentials to the database on the server:

  • %%ENV%%_URL
  • %%ENV%%_WP_PATH
  • %%ENV%%_DB_HOST
  • %%ENV%%_DB_NAME
  • %%ENV%%_DB_USER
  • %%ENV%%_DB_PASSWORD

• wp deploy push %%env%% --what=uploads: In order to push the uploads directory, you need to define the path to the uploads directory on your server:

  • %%ENV%%_UPLOADS_PATH

wp deploy pull: In order to pull to your server, you need to define the ssh credentials constants. These constants are needed whatever the arguments assed to the pull subcommand: * %%ENV%%_USER * %%ENV%%_HOST

• wp deploy pull %%env%% --what=db: In order to pull the database to from your server, you need to define the url of your remote WordPress website, the path to the WordPress code on your server, and the credentials to the database on the server:

  • %%ENV%%_PATH
  • %%ENV%%_URL
  • %%ENV%%_WP_PATH
  • %%ENV%%_DB_HOST
  • %%ENV%%_DB_NAME
  • %%ENV%%_DB_USER
  • %%ENV%%_DB_PASSWORD

• wp deploy push %%env%% --what=uploads: As in the push command's case, in order to pull the remote server uploads, we need their path on the server.

  • %%ENV%%_UPLOADS_PATH

• wp deploy push %%env%% --what=themes: As in the push command's case, in order to pull the remote server themes, we need their path on the server.

  • %%ENV%%_THEMES_PATH

• wp deploy push %%env%% --what=plugins: As in the push command's case, in order to pull the remote server plugins, we need their path on the server.

  • %%ENV%%_PLUGINS_PATH

• wp dump %%env%%: This subcommand only requires the path to the target WordPress path and its URL.

You can optionally define a constant with bash code which is called at the end of the subcommand execution.

You can refer to environment variables using placeholders. Some of the available environment variables are:

• env: The environment handle
• command: The subcommand (Currently push, pull, or dump).
• what: The what argument value for the push or pull subcommand.
• wd: The path to the working directory for the deploy command. This is the directory where the database is pulled, and other temporary files are created.
• timestamp: The date formatted with "Y_m_d-H_i"
• tmp_path: The path to the temporary files directory used by the deploy tool.
• bk_path: The path to the backups directory used by the deploy tool.
• local_uploads: The path to the local WordPress instance uploads directory.
• ssh: The ssh server handle in the user@host format.

Example

Here's an example of a DEV_POST_HOOK that posts a message to a hipchat room after a pull or a push is performed using the HipChat REST API (https://github.com/hipchat/hipchat-cli). For pushes, it also clears the cache.

<?php
$hipchat_message = "http://%%url%%"
	. "\njeandoe has successfully %%command%%ed %%what%%";
$command = "if [[ '%%command%%' != 'dump' ]]; then "
		. "echo '$hipchat_message' | %%abspath%%/hipchat-cli/hipchat_room_message -t 1245678 -r 123456 -f 'WP-Cli Deploy';"
	. "fi;"
	. "if [[ '%%command%%' == 'push' ]]; then "
		. "curl -Ss http://example.com/clear_cache.php?token=12385328523;"
	. "fi;";
define( 'DEV_POST_HOOK', $command );
