How to use virtualization and container technology on Kirin OS?

Virtualization and container technologies are widely used in modern computer systems, and they can provide more efficient resource utilization and flexible system management. Kirin operating system is a domestic operating system based on Linux. It has always adhered to the open source concept and provided powerful and stable platform support. This article will introduce how to use virtualization and container technology on Kirin OS.

1. Virtualization technology

1. Installing KVM virtualization tool

KVM is a virtualization solution based on the Linux kernel, which can convert physical The server is divided into multiple virtual machines and runs a different operating system in each virtual machine. To install KVM on the Kirin operating system, you can use the following commands:

sudo apt-get install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virt-manager -y

2. Create virtual machine

Creating a virtual machine requires an image file, which can be downloaded from the official website or created by yourself. Assume that the image file is named ubuntu.qcow2, and the command is as follows:

qemu-img create -f qcow2 ubuntu.qcow2 20G

Then use the virt-install command to create a virtual machine:

virt-install --name ubuntu --memory 2048 --vcpus 2 --disk path=/path/to/ubuntu.qcow2 --import --graphics vnc,listen=0.0.0.0 --noautoconsole

Among them, --name specifies the name of the virtual machine, --memory specifies the memory size of the virtual machine, --vcpus specifies the number of CPUs of the virtual machine, --disk specifies the hard disk path of the virtual machine, --import imports the existing Image file, --graphics sets the graphics mode of the virtual machine, --noautoconsole does not automatically open the console after creating the virtual machine.

3. Manage virtual machines

Use virt-manager to easily manage virtual machines. Enter the virt-manager command in the terminal to open the graphical interface, and you can create, start, and modify the configuration of the virtual machine.

2. Container technology

Container technology is a lightweight virtualization technology that can package applications and their dependencies into an independent, portable container and store them in Operate in different environments. When using container technology on Kirin operating system, you can choose Docker or Podman.

1. Install Docker

Docker is an open source container engine that can quickly build, deploy and run applications. To install Docker on Kirin operating system, you can use the following command:

sudo apt-get install docker.io -y

2. Create container

Use Docker Containers can be created and run quickly. The command is as follows:

sudo docker run -itd --name mycontainer ubuntu:18.04 /bin/bash

Among them, --name specifies the name of the container, ubuntu:18.04 is the image name of the container and label, /bin/bash is the command run by the container.

3. Manage containers

You can use the docker command to manage containers. For example, to view the list of containers, use the following command:

sudo docker ps -a

To stop a container, use the following command:

sudo docker stop mycontainer

四, Summary

This article introduces the method of using virtualization and container technology on Kirin operating system, and provides corresponding installation and usage examples. The application of virtualization and container technology can improve the utilization of computing resources, facilitate system management and application deployment, and make the Kirin operating system more flexible and scalable. Hope this article is helpful to readers.
