Module: VNET integrated SonarQube Azure Container Instance (+ Automatic SSL self-signed certificate)

Description

Terraform Registry module for setting up an (internal/private VNET integrated) AZURE hosted SonarQube ACI instance including private endpointed persistent PaaS Database (Azure SQL), PaaS File Share (Azure Files) and custom local domain using reverse proxy (Caddy) sidecar container with self-signed generated certificate.

See VNET integrated deployment - networking resources deployed separately:
For an example of how to create the required networking prerequisites separately to the SonarQube instance by setting the parameter: "var.create_networking_prereqs = false".

See VNET integrated deployment - networking resources deployed (Built-in):
For an example of how to create the required networking prerequisites and SonarQube instance in one module by setting the parameter: "var.create_networking_prereqs = true".

See VNET integrated deployment - existing network resources:
For an example on how to create and integrate the SonarQube instance on existing network resources by setting the parameter: "create_networking_prereqs = false".

Also see this module for creating a public instance of SonarQube using a Let's Encrypt Certificate. Module: Sonarqube Azure Container Instance (+ Automatic SSL).

This module is published on the Public Terraform Registry - sonarqube-aci-internal

Network prerequisites

The following networking resources are required to be created before deploying the SonarQube instance:

• Virtual Network (VNET)
• Private DNS Zones (Private DNS Zones for privatelink resources [Keyvault, MsSQL and File Storage], and a custom [local] domain)

• Subnets (Resource Subnet to private endpoint supporting resources, and a subnet delegated for Azure Container Instances)

Supporting PaaS resources are private endpointed and integrated with the VNET on the resources subnet and linked with DNS private zones attached to the VNET.

After the SonarQube instance is deployed, the SonarQube instance will be integrated with the VNET on the delegated-subnet and the private IP "A-record" linked with the DNS private [local] zone attached to the VNET.

SonarQube instance

The following resources are deployed as part of the SonarQube instance:

• Azure Container Group containing the SonarQube ACI and Caddy sidecar ACI with a private IP on the delegated-subnet of the VNET.
• Azure SQL Database (PaaS) with a private endpoint on the resources subnet of the VNET.
• Azure File Share (PaaS) with a private endpoint on the resources subnet of the VNET.
• Azure Key Vault (PaaS) with a private endpoint on the resources subnet of the VNET.

After the SonarQube instance is built, the SonarQube instance will be accessible on the custom domain name (e.g. https://sonar.custom.local) using the self-signed certificate generated by the Caddy sidecar container.

Ensure that any clients accessing the SonarQube instance have the relevant network peering in place with the SonarQube VNET and that the Private DNS custom local domain custom.local is linked with relevant VNETs for domain name resolution of the sonarqube instance.

When logging into the SonarQube instance for the first time, use the default credentials: admin/admin. This will then force you to update the default password:

if the container group is restarted or powered down/up, data is persisted in the Azure SQL database and Azure File Share.

Enjoy!
