#Quick Start

This document will help you quickly understand and use the Connectors system.

#Introduction

#Applicable Scenarios

The Connectors system provides a unified way to securely manage connections to external systems across your Kubernetes cluster. By using connectors, you can:

• Centralize credential management for external services
• Eliminate hardcoded credentials in application code
• Ensure consistent access patterns across your organization
• Monitor and audit service connections in one place

This guide uses GitHub as an example, but the same principles apply to connecting to other services.

#Estimated Reading Time

10-15 minutes

#Notes

• This quick start assumes you already have the Connectors Operator, ConnectorsCore, and ConnectorsGit components installed in your cluster. See the Installation Guide for detailed installation instructions.
• You need a GitHub account and a Personal Access Token (PAT) with appropriate permissions.
• Connector status reflects the health and accessibility of the connection.

#Prerequisites

• Kubernetes cluster with the following components installed:
  • Connectors Operator
  • ConnectorsCore
  • ConnectorsGit
• kubectl configured to communicate with your cluster
• GitHub account and valid Personal Access Token (PAT)
• Basic knowledge of Kubernetes resources

#Process Overview

No.	Operation Step	Description
1	Verify Required Components	Ensure connector infrastructure is properly installed
2	Create Authentication Secret	Create a Kubernetes Secret with GitHub credentials
3	Create GitHub Connector	Configure a connector to GitHub
4	Verify Connector Status	Check if the connector is ready for use

#Steps to Operate

#Step 1: Verify Required Components

Before creating a GitHub connector, verify that the connector infrastructure is properly installed in your cluster.

1. Check that the Connectors Operator, ConnectorsCore, and ConnectorsGit are installed:

   kubectl get connectorscore -A
   kubectl get connectorsgit -A

   You should see both resources with a status of "Ready".

2. Verify that the Git ConnectorClass exists:

   kubectl get connectorclass git

   If the Git ConnectorClass is not found, you need to install ConnectorsGit first. See the Installation Guide for instructions.

#Step 2: Create Authentication Secret

Create a Kubernetes Secret containing the credentials for GitHub.

1. Execute the following command to create a Secret with your GitHub credentials:

   kubectl create secret generic github-auth \
     --namespace default \
     --type=kubernetes.io/basic-auth \
     --from-literal=username=your-github-username \
     --from-literal=password=your-github-token

   Replace your-github-username with your GitHub username and your-github-token with your GitHub Personal Access Token.

2. Verify that the Secret was successfully created:

   kubectl get secret github-auth -n default

#Step 3: Create GitHub Connector

Create a connector to GitHub using the Git ConnectorClass.

1. Save the following YAML as github-connector.yaml:

   apiVersion: connectors.alauda.io/v1alpha1
   kind: Connector
   metadata:
     name: github-connector
     namespace: default
   spec:
     connectorClassName: git
     address: "https://github.com"
     auth:
       name: basicAuth
       secretRef:
         name: github-auth
         namespace: default

2. Apply the connector:

   kubectl apply -f github-connector.yaml

#Step 4: Verify Connector Status

After creating the connector, check its status to ensure it's functioning correctly.

1. Use the following command to check the connector status:

   kubectl get connector github-connector -n default

2. To view detailed status information, use:

   kubectl get connector github-connector -n default -o yaml

#Expected Results

After successfully completing all steps, you will see the following results:

1. The GitHub connector resource status shows as "Ready":

   NAME               CLASS   ADDRESS              READY   AGE
   github-connector   git     https://github.com   True    2m

2. All conditions in the detailed status information are "True":

   status:
     conditions:
     - type: ConnectorClassReady
       status: "True"
     - type: SecretReady
       status: "True"
     - type: LivenessReady
       status: "True"
     - type: AuthReady
       status: "True"
     - type: ProxyServiceReady
       status: "True"
     - type: Ready
       status: "True"

3. If the connector has proxy functionality configured, you will also see a proxy address in the status:

   status:
     proxy:
       httpAddress:
         url: http://c-github-connector.default.svc.cluster.local

Now, you have successfully created a GitHub connector and verified that it works.

Your applications can use this connector to securely access GitHub repositories without embedding credentials directly in application code.

#Troubleshooting

If your connector doesn't reach the "Ready" status, check the following:

1. ConnectorClass Availability: Ensure the Git ConnectorClass exists:

   kubectl get connectorclass git

   If it doesn't exist, you need to install ConnectorsGit. See the Installation Guide.

2. Authentication Configuration: Ensure the credentials in the Secret are correct and have appropriate permissions.

3. Repository Accessibility: Verify that the repository specified in the auth params exists and is accessible with the provided credentials.

4. Check Controller Logs: Review the connector controller logs for detailed error information:

   kubectl logs -n connectors-system -l app.kubernetes.io/name=connectors-controller-manager

#Next Steps

Now that you've created your first connector, you can:

• Create connectors for other Git services (GitLab, Harbor, etc.)
• Configure applications to use the connector for secure access to Git repositories
