Sonatype Nexus Repository OSS Integration

This documentation guide provides comprehensive instructions for integrating Sonatype Nexus Repository OSS (Nexus) with KubeRocketCI.

Prerequisites

Before proceeding, ensure that you have the following prerequisites:

• Kubectl version 1.26.0+ is installed. Please refer to the Kubernetes official website for details.
• Helm version 3.14.0+ is installed. Please refer to the Helm page on GitHub for details.

Installation

To install Nexus in your environment, it's recommended to use the resources provided in the Cluster Add-Ons repository. This approach involves installing both the Nexus repository manager and the nexus-operator. Leveraging the Cluster Add-Ons simplifies the deployment and management process, providing a streamlined method to integrate Nexus into your infrastructure.

1. Nexus Repository Manager: First, navigate to the Nexus section within the KubeRocketCI Cluster Add-Ons repository. Follow the instructions to deploy Nexus, ensuring it's correctly configured to serve as your artifact repository.

2. Nexus-Operator: Then, proceed with the nexus-operator installation. The operator facilitates easier management and automation of Nexus, allowing for seamless updates, configuration changes, and monitoring.

Configuration

To guarantee robust authentication and precise access control within the platform ecosystem, it's essential to establish a Service Account named ci.user. This account acts as a distinct identifier, enabling seamless integration and secure communication across the KubeRocketCI environment.

To create the Nexus ci.user and define repository parameters follow the steps below:

1. Open the Nexus UI and navigate to Server administration and configuration -> Security -> User. Click the Create local user button to create a new user:

   

2. Type the ci-user username, define an expiration period, and click the Generate button to create the token:

   

3. KubeRocketCI operates using a specific repository naming convention, where all repository names adhere to predefined standards. To align with this, navigate to Server administration and configuration -> Repository -> Repositories within Nexus. Here, repository creation is limited to those that match the required programming language, ensuring consistency and compliance with the KubeRocketCI framework.

   d) Click Create a repository by selecting "pypi(group)" and set the name as "edp-python-group". Add repository to group. Save the configuration.

4. Provision secrets using manifest, EDP Portal or with the externalSecrets operator

UI Portal

Go to EDP Portal -> EDP -> Configuration -> Nexus. Update or fill in the URL, nexus-user-id, nexus-user-password and click the Save button:

Manifests

apiVersion: v1
kind: Secret
metadata:
  name: ci-nexus
  namespace: edp
  labels:
    app.edp.epam.com/secret-type: nexus
    app.edp.epam.com/integration-secret: "true"
type: Opaque
stringData:
  url: https://nexus.example.com
  username: <nexus-user-id>
  password: <nexus-user-password>

External Secrets Operator

"ci-nexus":
{
  "url": "https://nexus.example.com",
  "username": "XXXXXXX",
  "password": "XXXXXXX"
},

Go to EDP Portal -> EDP -> Configuration -> Nexus and see Managed by External Secret message.
