Docker Scout integrates with a variety of tools and services, including Docker Hub, GitHub Actions, GitLab, CircleCI, and Jenkins. This makes it easy to incorporate Docker Scout into your existing CI/CD pipeline.

Benefits of Docker Scout

Docker Scout offers a number of benefits, including:

• Improved security: Docker Scout helps developers identify and remediate vulnerabilities in their Docker images. This improves the security of the software supply chain and helps to reduce the risk of security breaches.

  
  

• Increased reliability: Docker Scout helps developers identify and remediate misconfigurations in their Docker images. This improves the reliability of containerized applications and helps to reduce the risk of outages.

  
  

• Reduced costs: Docker Scout can help developers reduce the cost of developing and deploying containerized applications. This is because Docker Scout can help reduce the time and effort that is required to identify and remediate vulnerabilities and misconfigurations manually.

How to use Docker Scout

To use Docker Scout, you first need to create a Docker Scout account. Once you have created an account, you can start analyzing your Docker images.

To analyze a Docker image, you can use the Docker Scout CLI or the Docker Scout web interface. The Docker Scout CLI allows you to analyze Docker images from your local machine or from Docker Hub. The Docker Scout web interface allows you to analyze Docker images from Docker Hub, GitHub, GitLab, or CircleCI.

Once you have analyzed a Docker image, Docker Scout will generate a report that highlights any vulnerabilities, misconfigurations, or other potential security risks. The report will also provide recommendations for how to remediate any issues that are found.

3. Next Generation Docker Build

Docker announced the next-generation Docker Build at DockerCon. The next-generation Docker Build is a cloud-assisted build service that is designed to speed up and simplify the process of building Docker images.

The next-generation Docker Build works by automatically allocating resources in the cloud based on the needs of the build. This can significantly reduce the time it takes to build complex Docker images.

In addition, the next-generation Docker Build also supports team-wide build caching. This means that teams can share the results of their builds with each other, which can further reduce the time it takes to build Docker images.

The next-generation Docker Build is currently in public beta, but it is expected to be generally available in the coming months.

Benefits of the next-generation Docker Build

The next-generation Docker Build offers a number of benefits, including:

Faster builds: The next-generation Docker Build can significantly reduce the time it takes to build complex Docker images. This is because the next-generation Docker Build automatically allocates resources in the cloud based on the needs of the build.

4. Docker Debug

Docker Debug is a new tool that provides a unified debugging experience for containerized applications. It allows developers to debug containerized applications as if they were running locally, even if they are running in a remote environment.

Docker Debug works by creating a local debugging environment that is linked to the containerized application. This allows developers to use their favorite IDE or debugger to debug the containerized application, just as they would debug a local application.

Docker Debug also provides a number of features that make it easier to debug containerized applications, including:

• Breakpoints: Docker Debug allows developers to set breakpoints in containerized applications. When a breakpoint is reached, Docker Debug will stop the containerized application and allow the developer to inspect the state of the application.

  
  

• Stepping: Docker Debug allows developers to step through containerized applications line by line. This can be helpful for understanding the flow of execution in a containerized application.

  
  

• Variables: Docker Debug allows developers to inspect and modify variables in containerized applications. This can be helpful for understanding the state of a containerized application and for debugging errors.
