How to secure a repository in docker repository manager?


Asked by Valentin Randall on Dec 10, 2021 Docker



Creating an SSL (or TLS) certificate is the solution. With an SSL certificate entrusted to the reverse proxy, you can secure inbound connections to the Nexus server with repositories assigned unique HTTP ports. In other words, configure a repository connector for each Docker repository in the Nexus server.
Thereof,
Docker relies on secure connections using SSL to connect to the repositories. You are therefore required to expose the repository manager to your client tools via HTTPS. This can be configured via an external proxy server, which can also be used to scale your repositories, or directly with the repository manager.
Just so, You can create as many repos as you need and group them all in the group repo. This step is actually optional to use Nexus 3 as a Docker repository, because we can stick to pulling and pushing to the proxy and hosted repositories as will be discussed later.
Also Know,
Docker Hub is the original registry for Docker container images and it is being joined by more and more other publicly available registries such as the Google Container Registry and others. Nexus Repository Manager Pro and Nexus Repository Manager OSS support Docker registries as the Docker repository format for hosted and proxy repositories.
One may also ask,
A Docker image registry is the place to store all your Docker images. The image registry allows you to push and pull the container images as needed. Registries can be private or public.
