The last few days' emails have been about using Ansible to create and configure infrastructure, but it can also be used to deploy application code.
|
||
|
|
|
||
|
|
The simplest way being that an artifact is built locally - e.g. a directory of static HTML pages from a static site generator - and uploaded onto the server, and for this you could use Ansible's `synchronize` module.
|
||
|
|
|
||
|
|
It's a wrapper around the `rsync` command and makes it as simple as specifying `src` and `dest` values for the local and remote paths.
|
||
|
|
|
||
|
|
For more complicated deployments, I like to use a tool called Ansistrano - an Ansible port of a deployment tool called Capistrano.
|
||
|
|
|
||
|
|
It creates a new directory for each release and updates a `current` symlink to identify and serve the current release, and can share files and directories between releases.
|
||
|
|
|
||
|
|
As well as being able to configure settings such as the deployment strategy, how many old releases to keep, and even the directory and symlink names, there are a number of hooks that you can listen for an add your own steps as playbooks so you can install dependencies, generate assets, run migrations, or rebuild a cache as part of each deployment.
|
||
|
|
|
||
|
|
If you're running your applications in Docker, you could use Ansible to pull the latest images and restart your applications.
|
||
|
|
|
||
|
|
For more information and examples, I've given a talk on Ansible at various PHP events, which covers some Ansible basics before moving on to [deploying applications with Ansistrano]({{site.url}}/talks/deploying-php-ansible-ansistrano).
