But it can sometimes be hard to understand where to start or which layers can be reduced. With the Dive-In Docker extension, you can explore your docker image and its layer contents, then discover ways to shrink the size of your Docker/OCI image. 

With the Dive-In extension, you can:

• View the total size of your image.
• Identify the inefficient bytes.
• See an efficiency score.
• Identify the largest files in your image.
• View the size of each layer in your image.

Dive-In is an open source extension. Feel free to contribute or raise issues on https://github.com/prakhar1989/dive-in.

Building extensions? We’d love to hear from you!

Adding new extensions to the Extensions Marketplace is really exciting and we’d love to see more from our partners and the community. If you’re currently working on an extension or have built one in the past, we’d love to hear from you! And you can help us improve the developer experience for our Extensions SDK by taking this short survey.

Look inside Kubernetes clusters with Calyptia Core

Do you struggle to understand what’s happening inside your Kubernetes clusters? Do you need help with automating the logging and a simpler way to aggregate your observability data? If the answer is yes, the Calyptia Core extension is definitely worth trying! The extension allows developers to build, configure, and manage high performant Kubernetes-based observability data pipelines with point-and-click ease.

With the extension, you can:

• Eliminate the complexity of configuring and maintaining your observability pipeline
• Create an integration between Calyptia Core and your local Docker Desktop Kubernetes cluster
• Automate logging
• Create custom data pipelines with support for user-defined processing rules

Automate API testing with Postman’s Newman

Testing and debugging is an important part of any developer’s workflow. While working with APIs, you may need to automate API testing to run tests locally, run collections to assess the current status and health of your API, log test results and filter by test failures to debug unexpected API behavior, or run collections to execute an API workflow against different environment configurations.

Collections are a great way to handle these needs. With Postman collections and Postman’s Newman extension, you can run collections during development in both Docker Desktop and the command line.

See the resource usage of your containers

Docker stats is a great command for making it simple to see the amount of resources your containers are using. But what happens if you need to see resource usage over time? How do you see how much CPU and memory a Compose project is using?

That’s where the Resource Usage extension comes in. With this extension, you can:

• Analyze the most resource-intensive containers or Docker Compose projects
• Observe how resource usage changes over time for containers
• View how much CPU, memory, network, and disk space your containers use

Visualize your resource usage

Have you ever wanted an easier way to see which containers or Docker Compose projects consume the most resources, like CPU, memory, network, or disk I/O? The new Resource Usage extension displays all of this information right in Docker Desktop.

The extension displays a table view that shows CPU, memory, disk, and network I/O for all containers and aggregates them by Docker Compose project. You can start, stop, and restart containers or view container logs — all from the same place!

You can also visualize how these resources evolve over time:

Resource Usage is available on Docker Hub and the Docker Desktop Extensions Marketplace. Try it out and let us know what you think! 

Examine images for package vulnerabilities

Are you curious to know if the package dependencies in your images (or the base images you build on) contain vulnerabilities? Over the coming weeks, Docker Desktop will be rolling out an enhanced image detail view to help you understand if dependencies are introducing vulnerabilities into your image — and where those vulnerabilities are introduced:

Give it a try and see what you find. Don’t forget to join the Docker Community Slack to let us know what you think!

For some users on Mac OS, there’s a known issue with the installer that prevents the installation of a new helper tool needed for the experimental vulnerability and package discovery feature. To fix this, a symlink is needed that can be created with the following command:

sudo ln -s /Applications/Docker.app/Contents/Resources/bin/docker-index /usr/local/bin/docker-index

Regenerate the original run command of a Docker container

If you need to share docker container run details with a collaborator, or you just need to modify some parameters and run it again, then your life just got easier. The “Copy docker run” option lets you easily get back the original run command with all the parameters and details to reduce the hassle of trying to figure out exactly which environment variables are being used.

To try it out, select the actions icon for any container on the Docker Dashboard and choose “Copy docker run” to copy it, then paste and modify it anywhere you like!

What else would you like to know?

We’re always looking for new ways to make it simpler and faster for you to understand what’s going on with your containers and dev environments. Check out our public roadmap to see what’s in store and let us know what other visibility features you’d like to see.

And be sure to check out the release notes for a full list of everything new in Docker Desktop 4.14!
