Push and Pull Docker Images from GitLab with Access Token: A Complete Guide (2026)

Managing Docker images efficiently is a crucial aspect of modern DevOps practices. GitLab provides a secure and integrated container registry that allows you to store and manage your Docker images right alongside your source code. However, when two-factor authentication is enabled, you must use a personal access token instead of your password to authenticate Docker operations. This guide will walk you through the process of pushing and pulling Docker images from GitLab's registry using an access token, ensuring a seamless and secure workflow.

Key Takeaways

• Understand the importance of using access tokens for authentication.
• Learn how to generate and use a personal access token in GitLab.
• Step-by-step instructions to push and pull Docker images securely.
• Common errors and troubleshooting tips for Docker registry access.
• Ensure compatibility with the latest Docker and GitLab versions (2026).

In this tutorial, you'll learn why using a personal access token is crucial when working with GitLab's Docker registry, especially when two-factor authentication is enabled. We'll cover how to generate an access token with the necessary scopes and use it to authenticate your Docker CLI commands. This approach not only enhances security but also aligns with GitLab's recommended practices for API access. By the end of this guide, you'll be able to confidently manage your Docker images using GitLab's container registry.

Prerequisites

• Basic understanding of Docker and containerization concepts.
• A GitLab account with access to a GitLab project.
• Docker installed on your local machine (Docker version 24.0 or later).
• Two-factor authentication enabled on your GitLab account.
• Access to a terminal or command-line interface.

Step 1: Generate a Personal Access Token

To begin, you need a personal access token that GitLab can use to authenticate your Docker operations. This token will replace your password in CLI commands.

1. Log into your GitLab account.
2. Navigate to User Settings by clicking on your profile picture in the upper-right corner.
3. Select Access Tokens from the sidebar.
4. In the Name field, enter a descriptive name for your token, such as "Docker Registry Access".
5. Select the api scope. This is essential for Docker registry access.
6. Click Create personal access token.
7. Copy the generated token and store it securely. You will not be able to see it again!

Step 2: Log in to GitLab Container Registry

With your personal access token ready, you can now log in to the GitLab container registry using Docker CLI.

docker login registry.gitlab.com -u <your_username> -p <your_personal_access_token>

Replace <your_username> with your GitLab username and <your_personal_access_token> with the token you generated.

Step 3: Tag Your Docker Image

Before you can push an image to the GitLab registry, you need to tag it appropriately.

docker tag <local_image> registry.gitlab.com/<namespace>/<project>/<image_name>:<tag>

Replace placeholders with your actual image details, ensuring you use the correct namespace and project path.

Step 4: Push the Docker Image to GitLab

Now that your image is tagged, you can push it to the GitLab registry.

docker push registry.gitlab.com/<namespace>/<project>/<image_name>:<tag>

Monitor the output to ensure the image is uploaded successfully.

Step 5: Pull Docker Image from GitLab

To pull an image from the GitLab registry, use the following command:

docker pull registry.gitlab.com/<namespace>/<project>/<image_name>:<tag>

This command retrieves the image to your local environment.

Common Errors and Troubleshooting

If you encounter errors such as unauthorized: HTTP Basic: Access denied, ensure the following:

• Verify that your personal access token has the correct scopes.
• Ensure you're using your GitLab username, not your email, in the docker login command.
• Check that your Docker CLI is updated to the latest version.
• Confirm that your network settings allow access to the GitLab registry.

Frequently Asked Questions

Do I need to regenerate the access token regularly?

Yes, it is a good practice to periodically regenerate your access token for security reasons.

Can I use this method with CI/CD pipelines?

Yes, you can store the access token as a secret variable in your GitLab CI/CD pipeline configuration.

What if I lose my access token?

If you lose your token, you will need to generate a new one from GitLab's Access Tokens page.
