+# Host a Serverless Wordpress Site with Cloud Run
+
+## Introduction
+
+_This architecture uses click-to-deploy so you can spin up infrastructure in minutes using terraform!_
+
+43% of the Web is built on Wordpress. Because of its simplicity and versatility, Wordpress can be used for internal websites and customer facing e-commerce platforms in small to large businesses, while still offering security. **Cloud Run automatically scales your WordPress application to handle any amount of traffic**, without requiring manual intervention. This means that your website can handle large traffic spikes, without worrying about capacity.
+
+Cloud Run allows you to deploy your WordPress application quickly and easily, with a few clicks or commands. You can deploy your application from a container image stored in a container registry or directly from a Git repository. This click-to-deploy architecture leverages the serverless and scalability benefits of using Cloud Run to host a Wordpress Application connected to a PostgreSQL instance.
+
+This repo is based on the Cloud Foundation Fabric blueprint available [here](https://github.com/GoogleCloudPlatform/cloud-foundation-fabric/tree/master/blueprints/third-party-solutions/wordpress/cloudrun).
+
+## Use cases
+
+These are some of the use cases you can build on top of this infrastructure:
+* Business websites
+* E-commerce websites
+* Portfolios
+* Non-profit websites
+* Educational Websites
+
+## Architecture
+
+![Wordpress on Cloud Run](architecture.png "Wordpress on Cloud Run")
+
+The main components that are deployed in this architecture are the following (you can learn about them by following the hyperlinks):
+
+* [Cloud Run](https://cloud.google.com/run): serverless PaaS offering to host containers for web-oriented applications, while offering security, scalability and easy versioning
+* [Cloud SQL](https://cloud.google.com/sql): Managed solution for SQL databases
+* [VPC Serverless Connector](https://cloud.google.com/vpc/docs/serverless-vpc-access): Solution to access the CloudSQL VPC from Cloud Run, using only internal IP addresses
+
+## Costs
+
+Pricing Estimates - We have created a sample estimate based on some usage we see from new startups looking to scale. This estimate would give you an idea of how much this deployment would essentially cost per month at this scale and you extend it to the scale you further prefer. Here's the [link](https://cloud.google.com/products/calculator#id=8a7471c9-98df-4b71-97de-6222d22484c8).
+
+
+## Setting up the project for the deployment
+
+This example will deploy all its resources into the project defined by the `project_id` variable. Please note that we assume this project already exists. However, if you provide the appropriate values to the `project_create` variable, the project will be created as part of the deployment.
+
+If `project_create` is set to null, the identity performing the deployment needs the `owner` role on the project defined by the `project_id` variable. Otherwise, the identity performing the deployment needs `resourcemanager.projectCreator` on the resource hierarchy node specified by `project_create.parent` and `billing.user` on the billing account specified by `project_create.billing_account_id`.
+
+## Deploy the architecture
+
+Before we deploy the architecture, you will need the following information:
+
+* The __service project ID__.
+* A __unique prefix__ that you want all the deployed resources to have (for example: awesomestartup). This must be a string with no spaces or tabs.
+* A __Wordpress image__ if you want to use your own, otherwise you can use the provided standard image.
+* A __list of Groups or Users__ with Service Account Token creator role on Service Accounts in IAM format, eg 'group:group@domain.com'.
+
+**Notes**:
+
+1. If you want to change your admin password later on, please note that you can only do so via the Wordpress user interface.
+2. If you have the [domain restriction org. policy](https://cloud.google.com/resource-manager/docs/organization-policy/restricting-domains) on your organization, you have to edit the `cloud_run_invoker` variable and give it a value that will be accepted in accordance to your policy.
+
+Click on the button below, sign in if required and when the prompt appears, click on “confirm”. It will walk you through setting up your architecture.
+
+[![Open Cloud Shell](https://gstatic.com/cloudssh/images/open-btn.svg)](https://shell.cloud.google.com/cloudshell/editor?cloudshell_git_repo=https%3A%2F%2Fgithub.com%2FGoogleCloudPlatform%2Fdeploystack-wordpress-on-cloudrun&cloudshell_image=gcr.io%2Fds-artifacts-cloudshell%2Fdeploystack_custom_image&cloudshell_git_branch=main&cloudshell_tutorial=tutorial.md)
+
+
+This is the startup screen that appears after clicking the button and confirming:
+
+![cloud_shell](cloud_shell.png)
+
+During the process, you will be asked for some user input. All necessary variables are explained at the bottom of this ReadMe file. In case of failure, you can simply click the button again.
+
+<center>
+<h4>🎉 Congratulations! 🎉  <br />
+You have successfully deployed the foundation for running Wordpress using CloudRun on Google Cloud.</h4></center>
+
+
+**Note**: 
+You might get the following error (or a similar one):
+
+``` {shell}
+│ Error: resource is in failed state "Ready:False", message: Revision '...' is not ready and cannot serve traffic.│
+```
+
+In case this happens, manually run
+``` {shell}
+    deploystack install
+```
+to run the installation again.
+
+## Using the Wordpress Installation
+
+Upon completion, you will see the output with the values for the Cloud Run service and the user and password to access the `/admin` part of the website. You can also view it later with:
+
+``` {shell}
+terraform output
+# or for the concrete variable:
+terraform output cloud_run_service
+```
+
+When clicking on the Wordpress link, it will immediately prompt you to register as an administrator. The password will be pre-filled and can be changed after registration. 
+
+## Cleaning Up Your Environment
+
+The easiest way to remove all deployed resources is to run the following command in Cloud Shell:
+
+``` {shell}
+deploystack uninstall
+```
+
+The above command will delete the associated resources so there will be no billable charges made afterwards.
+<!-- BEGIN TFDOC -->
+
+## Standalone deployment
+
+Since the scripts are based on Terraform, it is possible to deploy this solution through `Terraform` directly, without having to go through `Deploystack`.
+Just clone this repo, create a `terraform.tfvars` file with your own values and call the following commands:
+``` {shell}
+terraform init
+terraform plan -out=execplan.out
+terraform apply execplan.out
+```
+
+## Special Thanks
+A special thank you goes out to Natalia Strelkova (skalolazka) and Grigory Movsesyan, the original developers of this example architecture.

+# Host a Serverless Wordpress Site with Cloud Run
+
+## Let's get started!
+
+This example will deploy all its resources into the project defined by the `project_id` variable. Please note that we assume this project already exists. 
+
+However, if you provide the appropriate values to the `project_create` variable, the project will be created as part of the deployment.
+
+If `project_create` is left to null, the identity performing the deployment needs the owner role on the project defined by the project_id variable. 
+
+Otherwise, the identity performing the deployment needs `resourcemanager.projectCreator` on the resource hierarchy node specified by `project_create.parent` and `billing.user` on the billing account specified by `project_create.billing_account_id`.
+
+**Time to complete**: About 10 minutes
+
+Click the **Start** button to move to the next step.
+
+## Information required
+
+Before we deploy the architecture, you will need the following information:
+
+* __The service project ID__.
+* A __unique prefix__ that you want all the deployed resources to have (for example: awesomestartup). This must be a string with no spaces or tabs.
+* A __Wordpress image__ if you want to use your own, otherwise you can use the provided standard image.
+* A __list of Groups or Users__ with Service Account Token creator role on Service Accounts in IAM format, eg 'group:group@domain.com'.
+
+### Notes:
+
+1. If you want to change your admin password later on, please note that you can only do so via the Wordpress user interface.
+2. If you have the domain restriction org. policy on your organization, you have to edit the cloud_run_invoker variable and give it a value that will be accepted in accordance to your policy.
+
+## Deploy the architecture
+Congratulations! At this point you should have successfully deployed the foundations for running Wordpress using CloudRun on Google Cloud.
+
+### Note: 
+*** You might get the following error (or a similar one): ***
+
+```
+Error: resource is in failed state "Ready:False", message: Revision '...' is not ready and cannot serve traffic.
+```
+
+In case this happens, manually run the following command to run the installation again
+
+```bash
+deploystack install
+```
+
+## Using the Wordpress Installation
+
+Upon completion, you will see the output with the values for the Cloud Run service and the user and password to access the /admin part of the website. You can also view it later with:
+
+``` bash
+terraform output
+```
+
+or for the concrete variable:
+
+``` bash
+terraform output cloud_run_service
+```
+
+When clicking on the Wordpress link, it will immediately prompt you to register as an administrator. 
+
+The password will be pre-filled and can be changed after registration.
+
+## Cleaning Up Your Environment
+The easiest way to remove all deployed resources is to run the following command in Cloud Shell:
+
+```bash
+deploystack uninstall
+```
+
+The above command will delete the associated resources so there will be no billable charges made afterwards.
+
+## Variables & Outputs
+
+For full information on variables and outputs please refer to the [README](https://github.com/GoogleCloudPlatform/deploystack-wordpress-on-cloudrun/blob/main/README.md#variables) file
+
+## Congratulations

+<walkthrough-conclusion-trophy></walkthrough-conclusion-trophy>
