Docker Swarm VS Harbor

Docker - A containerization platform that allows developers to package applications and their dependencies into containers. Docker Compose can be used to define multi-container application stacks, including web servers, databases, and other services. Features powerful portability and consistency, supports rapid building, sharing, and container management, suitable for complex application architectures, and requires a learning curve.

This article wanted to be a brief and gentle introduction to the container and docker world, there is a lot more to learn so don’t hesitate to check the docker documentation.

It appears they have since reverted the decision but it used to require logging in:

Docker Documentation

Docker is a tool that can help the developer to run each dependency in containers. Find more about Docker at Docker Official.

According to Docker Docs, a Dockerfile is a text document that contains all the instructions a user could call on the command line to assemble an image. These instructions include actions like installing software, copying files, setting environment variables, and defining how an application should run.

Hello reader, it's Sourab here. Recently in one of my projects I used Docker and Nginx for deploying a React App to a front-end server. Let's see how I did it.

Now that you know a little more about Cosign, Notary, and DCT, we will take it one step further by using one of these tools: Cosign. For this example, we will use the simple Docker registry:2 reference image to run a simple registry. In a real-world scenario, a managed registry such as Harbor, Amazon ECR, Docker Hub, etc.

Have a look at harbor, you can also use it to follow the same methods for helm charts etc.

Or for something more advanced https://goharbor.io/

You can host your own image repo if your feeling feisty. Harbor is a graduated project from the CNCF and they are also working on a new implementation called Dragonfly. https://goharbor.io/

Does anybody know whether there could be something like an open/libre container registry?

Maybe the cloud native foundation or the linux foundation could provide something like this to prevent vendor lock-ins?

I was coincidentially trying out harbor again over the last days, and it seems nice as a managed or self-hosted alternative. [1] after some discussions we probably gonna go with that, because we want to prevent another potential lock-in with sonarpoint's nexus.

Does anybody have similar migration plans?
