title: Automated Static Website Publishing with Cloud Build description: Learn how to automate publishing your static website to Google Cloud Storage with Cloud Build. author: ahmetb tags: Cloud Build, Hosting, Cloud Storage date_published: 2017-03-13
This tutorial shows how to automate publishing a static HTML website using a custom domain name to Google Cloud Storage using Google Cloud Build.
- Automatically publish changes to your static website from the source control repository.
Before you begin
- Make sure you have a custom domain name (e.g. example.com).
- Make sure the source code for your static website is hosted on a GitHub or BitBucket repository.
- Make sure you verified ownership of your domain on Google Webmaster
Central. (Do not include
https://in the URL for the purposes of this demo.)
- Make sure you have a Project on the Google Cloud Platform (GCP) Console to host your website.
Set up a storage bucket
By uploading your website contents as files to Cloud Storage, you can
host your static website on buckets. First, you need to create a
bucket. Head to the Storage section of the GCP Console and type
in your domain name (e.g.
www.example.com) and create the bucket:
After the bucket is created, you need to make it readable by everyone. Go to the Storage Browser on the GCP Console, click the menu icon to the right of the bucket, and select “Edit Object Default Permissions”:
Then add the user
allUsers with “Reader” role and click “Save”:
Now, you need to configure the storage bucket to serve a static website. Click the “Edit Website Configuration” button on the list of buckets:
Specify the main page as "index.html" and click “Save”:
Now, configure your domain name’s DNS records to create a CNAME record that points to Cloud Storage. This makes clients requesting your website point to Cloud Storage APIs.
Set up automated builds
Note: If you do not have a repository on GitHub, you can fork this sample repository for the purposes of this tutorial.
Head over to the Cloud Build → Build Triggers section on the GCP Console and click “Add trigger”:
Then select GitHub as the source of your repository. In the next screen, you may be asked to authorize access to your GitHub account and repositories. This is needed for Google Cloud Source Repositories to mirror and create commit hooks on your GitHub repositories.
Then, pick your repository from the list. If you forked the sample repository above, pick it here:
In the next screen
- give this Build Trigger a name (e.g. publish-website)
- choose Build Configuration "cloudbuild.yaml"
- choose Trigger Type ”Branch”
- Set the file location to
Now, create a
cloudbuild.yaml file with the following contents in your
repository. Note that you can add files to your repository on GitHub’s website, or
by cloning the repository on your development machine:
steps: - name: gcr.io/cloud-builders/gsutil args: ["-m", "rsync", "-r", "-c", "-d", "./vision/explore-api", "gs://hello.alp.im"]
This YAML file declares a build step with the
gsutil -m rsync command and
makes sure that the website is uploaded to the storage bucket. The
accelerates upload by processing multiple files in parallel and the
avoids re-uploading unchanged files.
If you are using the sample repository, you should upload the
./vision/explore-api/ directory. If you would like to upload your entire
repository to the storage bucket, make sure to change this value to
. in the
The last command in the
args is the name of your storage bucket prefixed with
gs://. Be sure to change this argument to the correct value.
After saving the file, commit and push the changes:
git add cloudbuild.yaml git commit -m 'Add build configuration' git push
Trigger the first build
Once you push the
cloudbuild.yaml file to your repository and create the Build
Trigger, you can kick off the first build manually. Head over to the GCP Console
Build Triggers section, click “Run
Trigger”, and choose the branch (i.e. master) to build.
Now click the “Build history” on the left and watch the build job execute and succeed:
Remember that after now, every commit pushed to any branch of your GitHub repository will trigger a new build and publish contents to your website. If you need to change which git branches or tags you use for publishing, you can update the Build Trigger configuration.
Try it out
Point your browser to your website URL and see if it works:
After you no longer need the artifacts of this tutorial, you can clean up the following resources on Google Cloud Platform Console to prevent incurring additional charges:
- Storage: delete bucket named as your website
- Container Registry → Build Triggers: delete build trigger
- Development → Repositories: delete mirrored repository
