How to Push Docker Images in Artifactory with Token Authentication via Jenkins

In today's continuous integration (CI) processes, secure methods of authentication are crucial for maintaining efficient workflows and protecting sensitive information. If you're using Artifactory as your Docker registry and Jenkins for your CI pipeline, you may have been relying on the traditional username and password combination for authentication. However, many teams have started utilizing token-based authentication for a more secure approach. In this guide, we will explore how to update your Jenkins pipeline to allow Docker image pushes to Artifactory using token authentication.

The Problem: Username/Password Limitations

While username and password credentials can effectively grant you access to Artifactory, they can also present security risks such as credential leaks. To mitigate these risks, you are looking to transition to a token-based authentication system. You have already generated a token in Artifactory but are uncertain how to incorporate it into your existing Jenkins pipeline.

The Solution: Using Token Authentication

Here’s how you can modify your Jenkins pipeline to use a token instead of a username/password combination for Docker registry access. Follow these steps to make the transition seamless:

Step 1: Generate Your Token

Ensure that you've generated the token in Artifactory. This token will be used instead of your password.

Step 2: Update Jenkins Credentials

Instead of retaining the standard username/password credentials setup for DOCKER_REGISTRY_CREDS, you can replace it with your token. The format will be as follows:

Username: Use the username of the user account that generated the token.

Password: Use the generated token as the password.

Step 3: Modify the Jenkins Pipeline Code

You need to make slight modifications to your Jenkins pipeline code. Here's how to do it:

Replace the existing DOCKER_REGISTRY_CREDS with your token-based credentials setup.

Here is how your Jenkins pipeline stage should look after the changes:

Step 4: Test the Pipeline

After updating your Jenkins pipeline, it's crucial to test the workflow to ensure that the Docker images are being pushed to Artifactory successfully without any authentication issues. Watch for any errors related to authentication, and double-check your token if any problems arise.

Wrapping Up

Transitioning to token-based authentication for Docker image pushes in Artifactory through Jenkins is not only a best practice for elevating your security measures but also enhances the overall efficiency of your CI/CD pipeline. By following the steps outlined above, you will be able to configure your Jenkins job to authenticate your Docker registry actions using a token rather than traditional credentials.

If you face any challenges during implementation, feel free to check the documentation for both Jenkins and Artifactory, or reach out to the support communities for assistance. Happy coding!
