Hosting on KeyCDN

Accelerate your Hugo site globally with a KeyCDN integration. This tutorial shows you how to setup your static site as a GitLab page behind a KeyCDN pull zone.

KeyCDN provides a multitude of features to help accelerate and secure your Hugo site globally including Brotli compression, Let’s Encrypt support, Origin Shield, and more.

Assumptions  

  • You already have a Hugo page configured
  • You have a GitLab account
  • You have a KeyCDN account

Create a KeyCDN Pull Zone  

The first step will be to login to your KeyCDN account and create a new zone. Name this whatever you like and select the Pull Zone option. As for the origin URL, your site will be running on GitLab Pages with a URL of https://youruser.gitlab.io/reponame/. Use this as the Origin URL.

While the origin location doesn’t exist yet, you will need to use your new Zone URL address (or Zone Alias) in the .gitlab-ci.yml file that will be uploaded to your GitLab project.

Ensure that you use your Zone URL or Zone alias as the BASEURL variable in the example below. This will be the user-visible website address.

Configure Your .gitlab-ci.yml File  

Your .gitlab-ci.yml file should look similar to the example below. Be sure to modify any variables that are specific to your setup.

variables:
    BASEURL: "https://cipull-7bb7.kxcdn.com/"
    HUGO_VERSION: "0.26"
    HUGO_CHECKSUM: "67e4ba5ec2a02c8164b6846e30a17cc765b0165a5b183d5e480149baf54e1a50"
    KEYCDN_ZONE_ID: "75544"

before_script:
    - apk update
    - apk add curl

pages:
    stage: deploy
    script:
    - apk add git
    - git submodule update --init
    - curl -sSL https://github.com/gohugoio/hugo/releases/download/v${HUGO_VERSION}/hugo_${HUGO_VERSION}_Linux-64bit.tar.gz -o /tmp/hugo.tar.gz
    - echo "${HUGO_CHECKSUM}  /tmp/hugo.tar.gz" | sha256sum -c
    - tar xf /tmp/hugo.tar.gz hugo -C /tmp/ && cp /tmp/hugo /usr/bin
    - hugo --baseURL ${BASEURL}
    - curl "https://api.keycdn.com/zones/purge/${KEYCDN_ZONE_ID}.json" -u "${KEYCDN_API_KEY}:"
    artifacts:
    paths:
    - public
    only:
    - master

Using this integration method, you will have to specify the Zone ID and your KeyCDN API key as secret variables. To do this, navigate to the top-left menu bar in GitLab and select Projects. Then, select your project and click on the Settings page. Finally, select Pipelines from the sub-menu and scroll down to the Secret Variable section.

The Secret Variable for your Zone ID should look similar to:

While the Secret Variable for your API Key will look similar to:

The Zone ID and API key are used to purge your zone – it’s not strictly needed but otherwise, the CDN might deliver older versions of your assets for quite a while.

Push Your Changes to GitLab  

Now it’s time to push the newly created repository to GitLab:

git remote add origin git@gitlab.com:youruser/ciexample.git
git push -u origin master

You can watch the progress and CI job output in your Gitlab project under “Pipelines”.

After verifying your CI job ran without issues, first check that your GitLab page shows up under https://youruser.gitlab.io/reponame/ (it might look broken depending on your browser settings as all links point to your KeyCDN zone – don’t worry about that) and then by heading to whatever Zone alias / Zone URL you defined.
