Sometimes it is inconvenient to use a public repository such as Docker Hub, and the company's private images are not pushed to the docker hub for business security. You can create a local repository for private use. Similar to git and maven, it saves the server bandwidth for downloading and uploading images.What is docker registry?

. /appworkdir /apprun["Dnu","restore"]run ["Dnu","Build"] RUN rm-r/appThe principle is to copy the project file, then proceed dnu restore , and then delete the project file so that the desired NuGet package can be downloaded in the system. Publishing the base image to the Docker Hub can then be built with the following Dockerfile to save time.Little TricksAfter creating the underlying

1, actual combat purposes build an enterprise-private mirrored warehouse that meets push and pull mirroring from the development environment . When we use k8s to orchestrate and dispatch containers, the basic unit of the operation is mirroring, so we need to pull the mirror from the repository to the current working node. The use of a public Docker hub is perfectly suited to our needs and is very convenient, but the uploaded
