Nixery is a Docker-compatible container registry that is capable of transparently building and serving container images using Nix. Images are built on-demand based on the image name. For example: docker pull http://nixery.dev/shell/git/htop The command above will give you an image with an interactive Shell, that also has git and htop installed. Keep adding more path …
Interesting take by the folks at nystudio107: instead of installing things such as node locally, why not run it in a container with an alias linked to it? Instead of installing all of the tools & packages you’re used to using, we use Docker images that someone else has created that contain these tools & …

Solid list of tips by the folks over at Snyk: By the time you’re at number 8 your mind may have dwelled, but don’t skip out on that step though! It not only allows you to build smaller images but also prevents you from having unnecessary files (read: security risks) left inside your container. Basically …

You can use dive to help you optimize your Docker image layers. Say you have these two layers in your Dockerfile: RUN wget http://xcal1.vodafone.co.uk/10MB.zip -P /tmp RUN rm /tmp/10MB.zip Then you’ll end up with 10MB of wasted space. dive will tell you, so that you can combine these into one optimized layer: RUN wget http://xcal1.vodafone.co.uk/10MB.zip …
It’s impossible to work with docker containers without docker images. In this post I want to talk about what makes docker images possible: the overlay filesystems. Interesting to know how things work behind the scenes. How are docker images built? A look into the Linux overlay file-systems and the OCI specification →

When building Docker images locally it will leverage its build cache: When building an image, Docker steps through the instructions in your Dockerfile, executing each in the order specified. As each instruction is examined, Docker looks for an existing image in its cache that it can reuse, rather than creating a new (duplicate) image. Therefore …

Building and pushing an image becomes really easy: uses: docker/build-push-action@v1 with: username: ${{ secrets.DOCKER_USERNAME }} password: ${{ secrets.DOCKER_PASSWORD }} repository: myorg/myrepository tags: latest Amongst other options you can also …

Recently I was invited as a speaker to Full Stack Ghent and PHP-WVL. At both events I brought a new talk called “Going Serverless with Google Cloud Run”. Cloud Run is a fully managed compute platform by Google that automatically scales stateless containers. By abstracting away all infrastructure management, us developers can focus on what …
