| # Serverless phpIPAM on Cloud Run | ||
|
|
||
| [phpIPAM](https://phpipam.net/) is an open-source IP address management (IPAM) | ||
| system that can be used to manage IP addresses in both on-premises and cloud | ||
| environments. It is a powerful tool that can help businesses to automate IP | ||
| address management, proactively identify and resolve IP address conflicts, and | ||
| plan for future IP address needs. | ||
|
|
||
| This repository aims to speed up deployment of phpIPAM software on Google Cloud | ||
| Platform Cloud Run serverless product. The web application can be exposed either | ||
| publicly via Global Application Load Balancer or internally via Internal | ||
| Application Load Balancer. More information on the architecture section. | ||
|
|
||
| ## Architecture | ||
|
|
||
|  | ||
|
|
||
| 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 | ||
| - [Global Application Load Balancer](https://cloud.google.com/load-balancing/docs/https) (\*): | ||
| An external Application Load Balancer is a proxy-based Layer 7 load balancer | ||
| that enables you to run and scale your services behind a single external IP | ||
| address. | ||
| - [Cloud Armor](https://cloud.google.com/armor/docs/cloud-armor-overview) (\*): | ||
| Help protect your applications and websites against denial of service and web | ||
| attacks. | ||
| - [Identity Aware Proxy](https://cloud.google.com/iap/docs/concepts-overview) (\*): | ||
| IAP lets you establish a central authorization layer for applications accessed | ||
| by HTTPS, so you can use an application-level access control model instead of | ||
| relying on network-level firewalls. | ||
| - [Regional Internal Application Load Balancer](https://cloud.google.com/load-balancing/docs/l7-internal) (\*): | ||
| A Google Cloud internal Application Load Balancer is a regional proxy-based | ||
| layer 7 load balancer that enables you expose your services behind a single | ||
| internal IP address. | ||
|
|
||
| > (\*) Product deployment depends on input variables | ||
| ## Setup | ||
|
|
||
| ### Prerequisites | ||
|
|
||
| #### 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 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`. | ||
|
|
||
| ### Deployment | ||
|
|
||
| #### Step 0: Cloning the repository | ||
|
|
||
| If you want to deploy from your Cloud Shell, click on the image below, sign in | ||
| if required and when the prompt appears, click on “confirm”. | ||
|
|
||
| [](https://shell.cloud.google.com/cloudshell/editor?cloudshell_git_repo=https%3A%2F%2Fgithub.com%2FGoogleCloudPlatform%2Fcloud-foundation-fabric&cloudshell_workspace=blueprints%2Fthird-party-solutions%2Fwordpress%2Fcloudrun) | ||
|
|
||
| Otherwise, in your console of choice: | ||
|
|
||
| ```bash | ||
| git clone https://github.com/GoogleCloudPlatform/cloud-foundation-fabric | ||
| ``` | ||
|
|
||
| Before you deploy the architecture, you will need at least the following | ||
| information (for more precise configuration see the Variables section): | ||
|
|
||
| * The project ID. | ||
|
|
||
| #### Step 2: Prepare the variables | ||
|
|
||
| Once you have the required information, head back to your cloned repository. | ||
| Make sure you’re in the directory of this tutorial (where this README is in). | ||
|
|
||
| Configure the Terraform variables in your `terraform.tfvars` file. | ||
| See [terraform.tfvars.sample](terraform.tfvars.sample) as starting point - just | ||
| copy it to `terraform.tfvars` and edit the latter. See the variables | ||
| documentation below. | ||
|
|
||
| **Notes**: | ||
|
|
||
| 1. 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. | ||
| 2. By default, the application will be exposed externally through Global | ||
| Application Load Balancer, for restricting access to specific identities | ||
| please check IAP configuration or deploy the application internally via the | ||
| ILB | ||
| 3. Setting the `phpipam_exposure` variable to "INTERNAL" will deploy an Internal | ||
| Application Load Balancer on the same VPC. This might be the preferred option | ||
| for enterprises since it prevents exposing the application publicly still | ||
| allowing internal access through private network (via either VPN and/or | ||
| Interconnect) | ||
|
|
||
| #### Step 3: Deploy resources | ||
|
|
||
| Initialize your Terraform environment and deploy the resources: | ||
|
|
||
| ```shell | ||
| terraform init | ||
| terraform apply | ||
| ``` | ||
|
|
||
| #### Step 4: Use the created resources | ||
|
|
||
| Upon completion, you will see the output with the values for the Cloud Run | ||
| service and the user and password to access the application. | ||
| You can also view it later with: | ||
|
|
||
| ```shell | ||
| terraform output | ||
| # or for the concrete variable: | ||
| terraform output cloud_run_service | ||
| ``` | ||
|
|
||
| Please be aware that the password created in the script is not yet configured in the | ||
| application, you will be prompted to insert that during phpIPAM installation | ||
| process at first login. | ||
| To access the newly deployed application follow these instructions: | ||
|
|
||
| 1. Get the default phpIPAM url from the terraform output in the form | ||
| {IP_ADDRESS}.nip.io | ||
| 2. Open your browser at that URL and you will see your phpIPAM installation page | ||
| like the following one: | ||
|
|
||
|  | ||
|
|
||
| 3. Click on "New phpipam installation". On the next page click "Automatic | ||
| database installation", you will be prompted to the following form: | ||
|
|
||
|  | ||
|
|
||
| 4. Insert "admin" as the MySQL username and the password available on the | ||
| terraform output of this command below (without quotes). | ||
| Untick the "Create new database" otherwise you'll get an error during | ||
| installation, leave all the other values as default and then click on " | ||
| Install phpipam database" | ||
|
|
||
| ``` | ||
| terraform output cloudsql_password | ||
| ``` | ||
|
|
||
| 5. After some time a "Database installed successfully!" message should pop up. | ||
| Then click "continue" and you'll be prompted to the last form for configuring | ||
| admin credentials: | ||
|
|
||
|  | ||
|
|
||
| 6. Insert the phpipam password available in the output of the following command | ||
| and choose a site title. Then insert the site url and click "Save | ||
| settings". "A Settings updated, installation complete!" message should pop up | ||
| and clicking "Proceed to login." will redirect you to the login page. | ||
| Be aware this is just a convenient way to have a backup admin password in | ||
| terraform, you could use whatever password you prefer. | ||
|
|
||
| ``` | ||
| terraform output phpipam_password | ||
| ``` | ||
|
|
||
| 7. Insert "admin" as username and the password configured on the previous step | ||
| and after login you'll finally get to the phpIPAM homepage. | ||
|
|
||
|  | ||
|
|
||
| ### Cleaning up your environment | ||
|
|
||
| The easiest way to remove all the deployed resources is to run the following | ||
| command in Cloud Shell: | ||
|
|
||
| ``` {shell} | ||
| terraform destroy | ||
| ``` | ||
|
|
||
| The above command will delete the associated resources so there will be no | ||
| billable charges made afterwards. | ||
