As part of re-building this site with [Sculpin](http://sculpin.io), I wanted to automate the deployments, as in I
wouldn't need to run a script like
[publish.sh](https://raw.githubusercontent.com/sculpin/sculpin-blog-skeleton/master/publish.sh) locally and have that
deploy my code onto my server. Not only did that mean that my local workflow was simpler (update, commit and push,
rather than update, commit, push and deploy), but if I wanted to make a quick edit or hotfix, I could log into GitHub or
Bitbucket (wherever I decided to host the source code) from any computer or my phone, make the change and have it
deployed for me.

I'd started using [Jenkins CI](http://jenkins-ci.org) during my time at the Drupal Association, and had since built my
own Jenkins server to handle deployments of Drupal websites, so that was the logical choice to use.

## Installing Jenkins and Sculpin
If you dont already have Jenkins installed and configured, I'd suggest using [Jeff Geerling](http://jeffgeerling.com/)
(aka geerlingguy)'s [Ansible role for Jenkins CI](https://galaxy.ansible.com/list#/roles/440).

I've also released an [Ansible role for Sculpin](https://galaxy.ansible.com/list#/roles/4063) that installs the
executable so that the Jenkins server can run Sculpin commands.

## Triggering a Build from a Git Commit
I created a new Jenkins item for this task, and restricted where it could be run to `master` (i.e. the Jenkins server
rather than any of the nodes).

### Polling from Git
I entered the url to the [GitHub repo](https://github.com/opdavies/oliverdavies.uk) into the **Source Code Management**
section (the Git option *may* have been added by the [Git plugin](https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin) that I have installed).

As we dont need any write access back to the repo, using the HTTP URL rather than the SSH one was fine, and I didnt
need to provide any additional credentials.

Also, as I knew that Id be working a lot with feature branches, I entered `*/master` as the only branch to build. This
meant that pushing changes or making edits on any other branches would not trigger a build.

I also checked the **Poll SCM** option so that Jenkins would be routinely checking for updated code. This essentially
uses the same syntax as cron, specifying minutes, hours etc. I entered `* * * * *` so that Jenkins would poll each
minute, knowing that I could make this less frequent if needed.

This now that Jenkins would be checking for any updates to the repo each minute, and could execute tasks if needed.
### Building and Deploying
Within the **Builds** section of the item, I added an *Execute Shell* step, where I could enter a command to execute.
Here, I pasted a modified version of the original publish.sh script.

This essentially is the same as the original file, in that Sculpin generates the site, and uses rsync to deploy it
somewhere else. In my case, `prodwww2` is a Jenkins node (this alias is configured in `/var/lib/jenkins/.ssh/config`),
and `/var/www/html/oliverdavies.uk/htdocs` is the directory from where my site is served.

## Building Periodically
There is some dynamic content on my site, specifically on the Talks page. Each talk has a date assigned to it, and
within the Twig template, the talk is positoned within upcoming or previous talks based on whether this date is less or
greater than the time of the build.

I also didnt want to have to push an empty commit or manually trigger a job in Jenkins after doing a talk in order for
it to be positioned in the correct place on the page, so I also wanted Jenkins to schedule a regular build regardless of
whether or not code had been pushed, so ensure that my talks page would be up to date.

After originally thinking that I'd have to split the build steps into a separate item and trigger that from a scheduled
item, and amend my git commit item accordingly, I found a **Build periodically** option that I could use within the same
item, leaving it intact and not having to make amends.

I set this to `@daily` (the same `H H * * *` - `H` is a Jenkins thing), so that the build would be triggered
automatically each day without a commit, and deploy any updates to the site.

## Next Steps
This workflow works great for one site, but as I roll out more Sculpin sites, I'd like to reduce duplication. I see this
mainly as Ill end up creating a separate `sculpin_build` item thats decoupled from the site that its building, and
instead passing variables such as environment, server name and docroot path as parameters in a parameterized build.

I'll probably also take the raw shell script out of Jenkins and save it in a text file that's stored locally on the
server, and execute that via Jenkins. This means that Id be able to store this file in a separate Git repository with
my other Jenkins scripts and get the standard advantages of using version control.
