Buildout recipe making versioned remote deploys trivial.

Project description

praekelt.recipe.deploy

Buildout recipe making versioned remote deploys trivial.

Creates a bin/ script with which you can easily deploy buildouts to remote servers. Uses Fabric to communicate and run commands on remote servers.

NOTE: This recipe is under active development and has not been fully tested in a production environment. Use at your own risk.

The deploy process proceeds as follows:

  1. The remote host as specified in host is accessed.

  2. A new release path structure is created using this pattern: <root_path>/releases/<release_timestamp>.

  3. The git repo as specified in git_url is cloned.

  4. The newly cloned repo’s branch is switched to the branch as specified in git_branch. If git_branch is not specified no switch occurs.

  5. Shared resources as specified in shared_resources are copied from the current release(if present) to the newly created release.

  6. The Buildout’s boostrap.py is run using the python executable as specified in python_exec and a Buildout configuration file as specified in conf_file. python is used by default if python_exec is not specified, buildout.cfg is used by default if conf_file is not specified.

  7. The Buildout is run using a Buildout configuration file as specified in conf_file. buildout.cfg is used by default if conf_file is not specified.

  8. The <root_path>/current symlink is updated to point to newly created release.

  9. Supervisor is updated($ supervisorctl update) if update_supervisor is specified as True.

  10. Each command specified in initd_commands is run in order.

Usage

Add a part in buildout.cfg like so:

[buildout]
parts = deploy

[deploy]
recipe = praekelt.recipe.deploy
git_url = git@github.com:me/projectx.git
host = www.protectx.com
root_path = /var/www/projectx

Running the buildout will add a deploy script with the same name as your deploy part in the bin/ directory. In this case bin/deploy. The resulting script will deploy git@github.com:me/projectx.git to www.projectx.com’s /var/www/projectx path.

Options

as_user

User as which to perform the deploy. Used to setup permissions appropriately and to clone from github. Defaults to ‘www-data’.

conf_file

Buildout cfg file with which to run boostrap and buildout. Defaults to ‘buildout.cfg’.

cron_commands

Commands to add to the as_users user’s crontab.

deploy_key_path

Path on host to key to use when cloning the repo.

git_branch

Git repo branch with which to perform the deploy.

git_url

Git repo with which to perform the deploy. Required.

host

Hostname on which to perform deploy. Required.

initd_commands

init.d commands to run after a completed deploy. i.e. nginx restart.

python_exec

Python command with which to boostrap Buildout. Defaults to ‘python’.

root_path

Root path in which to perform the deploy. current/release path structure will be created within this path. Required.

shared_resources

Resource paths to copy accross from the current release to the new release on each deploy.

update_supervisor

Whether or not to update supervisor. Defaults to ‘False’.

Full Example

The following example illustrates all available options:

[buildout]
parts = deploy

[deploy]
recipe = praekelt.recipe.deploy
as_user = www-data
conf_file = production.cfg
deploy_key_path = /var/www/.ssh/projectx_deploy_key
git_branch = production
git_url = git@github.com:me/projectx.git
host = www.protectx.com
initd_commands = nginx restart
python_exec = python2.5
root_path = /var/www/projectx
shared_resources =
    eggs
    downloads
    log
    media
update_supervisor = True
cron_commands = * * * * * echo foobar

The resulting script will deploy git@github.com:me/projectx.git’s production branch to www.projectx.com’s /var/www/projectx path as user www-data. The git repo will be cloned using /var/www/.ssh/projectx_deploy_key as ssh key. The eggs, downloads, log and media paths will be copied from the current release to this new release. The buildout environment will be created using python2.5 and run using production.cfg as configuration file. After the buildout completes supervisor will be updated and /etc/init.d/nginx restart will be run. * * * * * echo foobar will be added to www-data user’s crontab.
