Installing software by using the Volcano Engine repository

A software repository is a server or repository that you use in Linux systems to obtain software packages. It contains many software packages and related metadata. After you add a software repository, you can use the package manager provided by the system to install or update software on your instance based on the software package information included in the software repository. You do not need to manually download installation packages from official software websites.

Applicable scenario

The open-source software mirror site of Volcano Engine is committed to providing domestic users with fast, reliable open-source software mirroring services. The site supports software repositories for mainstream platform versions such as Ubuntu, CentOS, and Debian. You can use the open-source software mirror site address of Volcano Engine as a software repository to enhance software installation speed. Learn more.

You can access the open-source software mirror site of Volcano Engine over the Internet and the Volcano Engine intranet.

Address for access over the Internet: https://mirrors.volces.com

Address for access over the Volcano Engine intranet: https://mirrors.ivolces.com

tip

By default, Volcano Engine replaces the addresses of public mirror software repositories for common Linux distributions with the intranet address of the open-source software mirror site of Volcano Engine. This way, you do not need to perform any configuration.

The open-source software mirror site of Volcano Engine synchronizes software repositories from the official websites of various software repositories once a day.

Procedure

Step 1: Configure the Volcano Engine software repository

Add a software repository.

tip

This step shows how to add the Volcano Engine software repository by using the intranet address for specific operating systems.

If you want to use the Volcano Engine software repository over the Internet, replace https://mirrors.ivolces.com in the command with https://mirrors.volces.com.

For information about how to add the Volcano Engine software repository for more Linux operating systems, see the open-source software mirror site of Volcano Engine.
