This article focuses on "how to deploy containers in Linux". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let the editor take you to learn how to deploy containers in Linux.

What are the main functions of the kernel?

The Linux kernel is an important part of running the operating system, and it is fairly consistent across distributions. At its core, the kernel has interrupt handlers, schedulers and supervisors. These three components can help the operating system run smoothly and process information. It also has some features that make Linux valuable in the enterprise.

The two main attributes of the Linux kernel are multi-user and multi-function. This means that you can have multiple administrators working on the same program at the same time. The obvious benefit of this is that you and your team can use the same file, operating system, and command line for various projects to improve collaboration and efficiency.

The Linux kernel also includes all parts related to hardware and application support.

How do I deploy containers in Linux?

With container technology, you can run applications in an independent and efficient manner, thereby reducing infrastructure utilization to a limited extent. Containerization on Linux has been around since 2008, and it is getting more attention with the introduction of tools such as Kubernetes, which was launched in 2015.

Kubernetes, originally developed by Google, is a container orchestration program. It helps you deploy, maintain, schedule, and extend container applications across server nodes. It is compatible with Docker and CoreOS Rkt, and these programs can be used for container creation, configuration, and deployment.

If you need to host an application and all its related components, Docker is ideal, and it offers alternatives to cloud-based servers. Common use cases are application testing and extension.

CoreOS, acquired by Red Hat in 2014, has Rkt, which runs as a binary on most Linux distributions. It runs pods (the application collection) as a container. Its components are completely open source and are very useful for large multi-machine deployments.

If you don't want to run Docker or CoreOS, you can use the systemd container feature of Linux.

Where should file and rights management begin?

A common Linux function is file management, all through the command line interface. Even if you prefer to use a graphical interface, it's helpful to understand some of the commands for file movement and creation.

Common commands for file information and management include:

Mkdir: generate a new directory using the name path

Cp: copying files and directories

Mv: move a file or directory to another file location

Tail: displays a few lines of the file

Ls: lists the files and directories running in the active directory and provides information about these components, such as the last open time and the last modified time.

These main commands can easily play files at random and easily create new directories.

What are the security features in Linux?

Because Linux is an open source operating system, you still have to ensure the security of data center hardware and information. One way is to use the Security Enhanced Linux (SELinux) kernel. It has three modes: enforcement, licensing, and disabling.

SELinux uses the least privilege model, which runs a specific written access policy. This means that if you write a policy script for the feature, the system only grants access to users and features.

Another well-known option is AppArmor, which you can run on SUSE Linux or openSUSE. AppArmor does not use write permissions, but uses configuration files as its security framework. These files include all the information necessary to protect the mandatory access control of the operating system.

Another reason you choose AppArmor is usability, because it allows you to customize the access profile in a few simple steps.

At this point, I believe you have a deeper understanding of "how to deploy containers in Linux". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
