when comparing the performance of Rails on Windows and dockerized Rails on Windows, we experience a 50% performance gain.

A layered container design helps to further reduce latencies and download volumes since unchanged layers can be cached.

compared to Hypervisor-based virtualization technologies, the resulting images are much more lightweight and thus are much easier to handle and share.

similar to Hypervisor based virtualization technologies, container technologies help to create portable application images by bundling libraries with the application and by providing an environment that is independent from other applications.

Here are the reasons, why I have chosen to containerize my web application using Docker:

Next Steps towards Continuous Integration.

If you are interested in a more lightweight „Hello World“ example with (probably) <15 MB of downloads during the process, you might be interested in this example.

Note: the procedure requires Internet downloads of >1 GB.

Next possible steps towards full CI/CD (continuous integration/continuous deployment) are discussed a the end of the blog.

This will allow us to automatically create a new Docker image in the background, each time a code change is pushed to the Software repository. In a second step, we will create a Link (via a „Webhook“) between the Github Software repository and the Docker Hub docker image repository.which base image to use, which files to copy, which commands to perform and which ports to expose. we will create and test a so-called Dockerfile that describes all automation steps: e.g.This blog is exploring a tiny aspect of this automation framework: the containerization of an application and the automatic creation of a Docker image from source code for a Rails Web application as target application. For that, Continuous Integration (CI) and continuous deployment (CD) are made easy. If you use the -f flag and specify the image’s short or long ID, then rmi untags and removes all images that match the specified ID.What, if you could release and deploy fully tested and bullet-proof software on a day by day basis? Isn’t this a huge effort for hobby developers like me? Even for hobby developers, Docker and its ecosystem promises an easy way to automate the integration and deployment of the software. Remove the repository/tag you don't need: docker rmi repository/image-name:tag If you want to do it manually, instead of using the image id to remove the images, you must remove the repository/tag that you don't need using image names: docker rmi a8e6fa672e89Įrror response from daemon: conflict: unable to delete a8e6fa672e89 (must be forced) - image is referenced in multiple repositories Repository2/image-name tag a8e6fa672e89 10 days ago 344MB

Repository/image-name tag a8e6fa672e89 10 days ago 344MB You cannot remove images having multiple repositories without the force modifier, see Docker docs for more info.
