  • To learn more about pulling and pushing Docker images to the container registry, as well as particular versioning, see this page.

  • Finally, Navigate to the container registry images interface in the cloud console to verify the pushed image in the container registry.

Step - 2: Create a Cloud SQL Instance with MySQL.

  • In the Console, Navigate to Cloud SQL, Create a new instance with MYSQL version 8.0, add "" under Authorized networks and create the instance.

  • Lastly, In the Cloud SQL interface, Navigate to Databases and create a new database for WordPress. For example, "my_wordpress_database".

Step - 3. Installing WordPress on Google Cloud Run.

  • Navigate to the Cloud Run interface in the Google cloud console and click on the "Create Service" option to deploy the WordPress.

  • Choose the "Deploy one revision from an existing container image" option in the create service interface and select the bitnami WordPress image from the container registry.

  • Then, type the service name and choose the region and specify the CPU allocation, pricing and auto-scaling options. Also, select the "Allow all traffic" option in the ingress and select the "Allow unauthenticated invocations" in the Authentication.

  • Next, Expand the "Container, Variables & Secrets, Connections, Security" option and type "8080" in the container port under the container tab.

  • Next, switch to the Variables tab, and add the following variables.

  • In the environment variables tab, add the following variable. Please remember to substitute the WordPress username, password, email, database host, port, username, and password with your values.

Environment Variable Name





WordPress administrator username. For example, manoj.



WordPress administrator password. For example, Admin@123


WordPress application email. For example,


Cloud SQL instance Public IP Address.



Port used by the MariaDB or MySQL server. By default, 3306.



Database name that WordPress will use to connect with the database. Refer Step -2.



Database user that WordPress will use to connect with the database. By default, Cloud SQL username is root.



Database password that WordPress will use to connect with the database. CloudSQL instance password. Refer Step - 2.

  • Finally, click on the "create" option to deploy the WordPress on Google Cloud Run.

  • To visit the website, click the URL once the deployment is complete. Please keep in mind that remembering the URL each time you want to access the website is difficult. Refer the Step-4 and assign a custom(your) domain to the Cloud Run service..

Step - 4. Assign a custom domain to your WordPress Cloud Run Service.

  • Navigate to the Cloud Run interface and click on the "Manage Custom Domains" option,

  • Click on the "Add Mapping" option in the Manage Custom Domains interface to point to your custom domain

  • Select the service to which you're mapping the custom domain from the Add Mapping interface.

  • Enter your domain name and click on continue to verify ownership of the domain.

  • Unless you bought your domain from Google, you must prove ownership before using it.

  • In case, If you have already verified the ownership of the domain, choose the domain from the "Select a verified domain" drop-down list and type the subdomain name in the "Specify Subdomain" field or leave it to a blank to point to the root domain.

  • Then, click on the "continue" option to update your DNS record at your domain registrar.

  • Lastly, add a CNAME record in your domain DNS points to ""

  • Finally, Click on the "Done" option in the add mapping interface.

  • When the domain mapping is finished, navigate your domain URL to browse the website.


Here are some recommended tips and tricks.

  • Custom domain mapping typically takes a long time. It usually takes a few minutes to load after the domain mapping is completed.

  • Keep in mind that if you disable the container registry service by accident, the Cloud Run service will collapse, and your website will become unavailable.
