This is a guest blog post by Ryan McGeary. Ryan runs Busyconf, where he aims to make conference planning easy. When we first saw his article we thought it would be a great tutorial about Continuous Integration and Continuous Deployment for static pages to publish on our blog. We got in contact with him and Ryan kindly provided his original article here.
I like to run continuous integration for my projects whenever possible, and this goes for static site repositories as much as regular code repositories.
Recently, I started playing with Codeship for Continuous Integration and Continuous Deployment. It’s a well-priced continuous service, and I wanted to be able to automatically deploy my middleman site upon successful builds to the master branch. It took a bit of trial and error, but I finally got something that works well.
Continuous Integration with Codeship – Test Settings
After initializing a new GitHub repository in Codeship, you’ll need to define how tests are run. Under the Test project settings in Codeship, select Ruby as the language and define your Setup Commands and Test Commands.
bundle exec middleman build
Perfect. Now your site will run a test build upon every code push.
Continuous Deployment with Codeship – Deployment Settings
This is where I had some trouble, but I finally found a set of commands that correctly deloyed to our
gh-pages branch in the repository. First, it’s worth mentioning that I use the middleman-gh-pages gem for deploying to the
gh-pages branch. This gem gives you a
rake publish task that handles most of the dirty work.
Under the Deployment project settings in Codeship, configure a deployment from the master branch using a Custom Script.
git config --global user.email "[email protected]" git config --global user.name "Codeship Robot" rm -rf build git remote set-branches --add origin gh-pages git fetch bundle exec rake publish sleep 30 wget --retry-connrefused --no-check-certificate -T 60 http://yoursite.com/
This configures a git user, removes the
build directory that was left there from the test steps, adds a
gh-pages remote branch (because Codeship only clones the relevant branch during setup), and runs the
rake publish task to deploy the site to the
If all went well, your site will automatically deploy to GitHub Pages upon a push and successful build in the master branch.
Extra Credit: Force Codeship to skip builds on the gh-pages branch.
Unfortunately, Codeship currently tries to run builds on all branches, including the
gh-pages branch. This is undesirable for this setup, so to avoid this, we also need to add ”–skip-ci” or “[skip ci]” to the commit message that is pushed to the gh-pages branch.
middleman-gh-pages doesn’t support that, but I opened a pull-request to add such support. If you’re interested in using it, change your Gemfile to point at this branch
gem "middleman-gh-pages", github: "rmm5t/middleman-gh-pages", branch: "commit-message-suffix"
Afterwards, you can add this to the bottom of your project’s Rakefile:
# Ensure builds are skipped when pushing to the gh-pages branch ENV["COMMIT_MESSAGE_SUFFIX"] = "[skip ci]"
We want to thank Ryan for making his original blog post available. If you have any questions feel free to write them in the comments or ping Ryan on twitter.
One of the bewildering things about DevOps is integrating the massive toolchain including the dozens of new tools that seem to crop up every year. Part of DevOps is Continuous Delivery and having a complex toolchain can add additional integration and setup to your developer environment. In his session at @DevOpsSummit at 18th Cloud Expo, Miko Matsumura, Chief Marketing Officer of Gradle Inc., will discuss which tools to use in a developer stack, how to provision the toolchain to minimize onboa...

Companies can harness IoT and predictive analytics to sustain business continuity; predict and manage site performance during emergencies; minimize expensive reactive maintenance; and forecast equipment and maintenance budgets and expenditures. Providing cost-effective, uninterrupted service is challenging, particularly for organizations with geographically dispersed operations.

There will be new vendors providing applications, middleware, and connected devices to support the thriving IoT ecosystem. This essentially means that electronic device manufacturers will also be in the software business. Many will be new to building embedded software or robust software. This creates an increased importance on software quality, particularly within the Industrial Internet of Things where business-critical applications are becoming dependent on products controlled by software. Qua...

As enterprises work to take advantage of Big Data technologies, they frequently become distracted by product-level decisions. In most new Big Data builds this approach is completely counter-productive: it presupposes tools that may not be a fit for development teams, forces IT to take on the burden of evaluating and maintaining unfamiliar technology, and represents a major up-front expense. In his session at @BigDataExpo at @ThingsExpo, Andrew Warfield, CTO and Co-Founder of Coho Data, will dis...

Eighty percent of a data scientist’s time is spent gathering and cleaning up data, and 80% of all data is unstructured and almost never analyzed. Cognitive computing, in combination with Big Data, is changing the equation by creating data reservoirs and using natural language processing to enable analysis of unstructured data sources. This is impacting every aspect of the analytics profession from how data is mined (and by whom) to how it is delivered. This is not some futuristic vision: it's ha...
