4. At the same time, Docker for Windows provides container interface management tools. You can right-click the Kitematic function in the menu to enter. The first time you may be prompted to download and i
code refactoring, you will see that there are a lot of mirrored versions. We've been building a separate image for each of the daemon (we'll do this when we integrate the patches). So the monitor, OSD, MDS and RADOSGW each have separate mirrors. This is not the ideal solution, so we are trying to integrate all the components into a mirror called daemon.This image contains all the modules that you can selectively activate from the command line while r

Open the Program. cs file and add UseUrls to construct the WebHostBuilder coherent method chain so that our application can accept requests from any IP address. This allows the application to accept HTTP requests in the docker container:
OK. After compilation, run the application using dotnet
Docker Basic Concepts
Docker is an open source application container engine that allows developers to package their apps and dependencies into a portable container, and then publish it to any popular Linux machine.
Docker is an open platform for redefining the process of program development testing, delivery, and deployment, and
specified command in this process. Developers can import the Os/exec package in the project, then populate the CMD structure, the path and program name of the program to be run, the parameters required by the program, environment variables, various operating system-specific properties and extended file descriptors.In Docker, the program populates the Application

Docker the expose command, you can map container internal ports by writing Dockerfile plus-p parameters, but for already running container, if you want to open up a new port, It's not easy to edit dockerfile and build again.
In fact,
memory of all containers is 995MB.Even in kubernetes/openshift clusters, the results are similar. I also executed a command in a cluster of 15G memory to make the Kubernetes pod have 511MB memory limit (command: "Kubectl run mycentos–image=centos-it–limits= ' memory=512mi '"), Total memory is displayed as 14GB.To find out why this is the result, you can read thi
