drone-deploy

This is a useful scripts collection for deploying with Drone CI.

Drone v0.8 Compatible

Features

• Uploading files with rsync or lftp
• Auto editing in each environments before uploading

Setup

1. Fork this repository

This scripts are triggered by Drone's Deployments. It will get this file hosted on this repository. This means that changes on this repository may affect your deployment immediately. So you shouldn't use this directly, you should fork this at first, then change these parts to yours. (just replace karappo/drone-deploy/ to your-acocunt/drone-deploy/)

2. Setup Drone on your server

Please install following this instruction.

Ref: Easily install Drone on Digital Ocean (Japanese)

This branch list shows drone compatibles.

3. Done! (See 'Usage')

Usage

1. Activate your project on Drone.
2. Add .drone.yml file into your project root
3. [Optional] Add include file and ignore file
4. Commit and push as usual

.drone.yml

The following contents are recommended.

.drone.yml

clone:
  git:
    image: plugins/git
    recursive: true
    depth: 1
    submodule_override:
      path/to/submodule: https://github.com:443/someone/sample.git
    when:
      branch: [ master ]
pipeline:
  build:
    image: karappo/dronedeploy:drone-0.8
    environment:
      - DEP_MASTER_COMMAND='rsync'
      - DEP_MASTER_HOST='sample.com'
      - DEP_MASTER_USER='username'
      - DEP_MASTER_HOST_DIR='htdocs'
    commands:
      - echo "$SSH_KEY" > ~/.ssh/id_rsa && chmod 600 ~/.ssh/id_rsa
      - curl https://raw.githubusercontent.com/karappo/drone-deploy/drone-compatible/v0.8/deploy.sh | bash
    secrets: [ ssh_key ]

Explaination of variables

clone.git.recursive

If you want to ignore submodules, you can set false to disable git recursive clone. This is optional. If you don't need it, you can remove the first 4 lines. Because default value is true.

clone.git.depth

To set 1 is recommended, because of making cloning faster.

clone.git.submodule_override

key: Set the path value in .gitmodules
value: Replacement URL(https, needs port setting) with the url value in .gitmodules.

Ref:

• Official Document

clone.git.when.branch

Adding conditions for cloning is recomended otherwise drone will do "cloning" after every branch pushing. Especialy you should check this configration when having heavy "build".

pipeline.build.image

Setting this to karappo/dronedeploy is recommended, because it's been installed necessary tools already, so this makes builds fater. Ref: karappo/dronedeploy

pipeline.build.environment [required]

These environment variables will be used in scripts. Replace [BRANCH] to your target branch name. If DEP_[BRANCH]_XXX won't be found, the scripts will use DEP_REMOTE_XXX instead. It's useful if you have some common settings between remote environments.

Required environment variables

Key	Value	Description
DEP_[BRANCH]_COMMAND	rsync or lftp	Sync command (rsync is recommended)
DEP_[BRANCH]_HOST	e.g. sample.com	Target remote host
DEP_[BRANCH]_USER		SSH or FTP username
DEP_[BRANCH]_PASSWORD		Not necessary if command is rsync and allow access with RSA authentication
DEP_[BRANCH]_HOST_DIR	e.g. /home/user/www,www	Use absolute path if command is rsync, or related path if command is lftp

Optional environment variables

Key	Value	Description
DEP_[BRANCH]_FTPS	yes or no	Default is yes. Set no only if remote doesn't accept FTPS
DEP_[BRANCH]_PORT	e.g. 2222	Activate only if command is rsync and using particular port other than 22
DEP_[BRANCH]_INCLUDE_FILE	e.g. ./.depinc.sh	URL allowed
DEP_[BRANCH]_IGNORE_FILE	e.g. ./.depignore, default	URL allowed

pipeline.build.commands [required]

This is the entry point of this system. Do NOT change.

pipeline.build.secrets

Please set secrets named ssh_key on your drone dashboard.

You may use ssh-keygen

ssh-keygen -f ~/Desktop/ssh_key -C 'project_name@drone.your.domain'

Include file

You can define custom processes before and after syncing in this file.

Examples purpose

• Switch DB settings by each environments
• Activate Basic Auth only on stating environment

Include file usage

Include file should have two methods like this.

.depinc.sh

before_sync(){
  # your process here
}
after_sync(){
  # your process here
}

You should set your include file with related path from your project's root.

.drone.yml

build:
  environment:
    - DEP_REMOTE_INCLUDE_FILE=./.depinc.sh

Or you can set this as URL.

.drone.yml

build:
  environment:
    - DEP_REMOTE_INCLUDE_FILE=https://raw.githubusercontent.com/karappo/drone-deploy/drone-compatible/v0.8/include-files/wordpress/.depinc.sh

If you set like above, these process below will be executed.

1. Remove #DEP_REMOTE_RM and #DEP_[BRANCH]_RM in .htaccess file
2. Remove //DEP_REMOTE_RM and //DEP_[BRANCH]_RM in .php files
3. Set the recommended permissions for WordPress after syncing

Ref: .depinc.sh

For WordPress

In WordPress project, you can write code like this.

wp-config.php

// Database Settings　-----------

// Local

// Activate only in local environment
//DEP_REMOTE_RM /*
define('DB_NAME', 'LOCAL_DATABASE');
define('DB_USER', 'root');
define('DB_PASSWORD', 'root');
define('DB_HOST', 'localhost');
//DEP_REMOTE_RM */

// Remote

// Activate only in master branch's deploy target
//DEP_MASTER_RM define('DB_NAME', 'PROD_DATABASE');
//DEP_MASTER_RM define('DB_USER', 'PROD_USER');
//DEP_MASTER_RM define('DB_PASSWORD', 'PROD_PASSWORD');
//DEP_MASTER_RM define('DB_HOST', 'PROD_HOST');

// Activate only in staging branch's deploy target
//DEP_STAGING_RM define('DB_NAME', 'STAGING_DATABASE');
//DEP_STAGING_RM define('DB_USER', 'STAGING_USER');
//DEP_STAGING_RM define('DB_PASSWORD', 'STAGING_PASSWORD');
//DEP_STAGING_RM define('DB_HOST', 'STAGING_HOST');

// Common

define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');

// -----------　/ Database Settings

And you can activate Basic Auth only in staging branch's target environment with this below.

.htaccess

# Basic Authentication -----------
#DEP_STAGING_RM <Files ~ "^\.(htaccess|htpasswd)$">
#DEP_STAGING_RM deny from all
#DEP_STAGING_RM </Files>
#DEP_STAGING_RM AuthUserFile /home/example/www/.htpasswd
#DEP_STAGING_RM AuthGroupFile /dev/null
#DEP_STAGING_RM AuthName "Please enter your ID and password"
#DEP_STAGING_RM AuthType Basic
#DEP_STAGING_RM require valid-user
#DEP_STAGING_RM order deny,allow
# ----------- / Basic Authentication

File Permissions

This is default permissions, you can edit for each project you have.

find ./ -type d -exec chmod 705 {} \;
find ./ -type f -exec chmod 604 {} \;
chmod 606 .htaccess
chmod 600 wp/wp-config.php

Prepared include files

There are some files for particular purposes or environments under the directory include-files.

Ignore file

This is a file for exclusion in syncing.

Example

.depignore

.git/
.sass-cache/
.gitignore
Procfile
README
README.*
/_assets/

# drone-deploy
.depignore
.depinc.sh
.drone.yml

You should set your ignore file with related path from your project's root.

.drone.yml

build:
  environment:
    - DEP_MASTER_IGNORE_FILE=./.depignore

FAQ

Got Fatal error: Certificate verification: Not trusted

If you got these errors, your remote server may not accept FTPS connection. Please set DEP_[BRANCH]_FTPS=no.

[DEPLOY] - sync -> via FTPS
ftp://user:password@host.com
mirror: Fatal error: Certificate verification: Not trusted
[DEPLOY] - sync -> [ERROR]

Disable deployment on particular timing

You can skip deployment by adding [CI SKIP] to the last commit message. Ammend your last commit or just add empty commit and push. Note this is case-insensitive.

git commit --allow-empty -m '[CI SKIP]'
