Installing Cloud-Init (EulerOS/openEuler)

Scenarios

Cloud-Init is a tool developed to initiate VMs or iMetal servers in a cloud environment. It is used to customize the network configuration, hostname, hosts file, username, and password for a VM or an iMetal server. Cloud-Init is also required if the password of a VM is generated by the system at random.

The Cloud-Init installation file has requirements on Linux versions and can only be installed from the Internet. Therefore, ensure that the server or VM on the original platform can access the Internet.

Description

The Cloud-Init installation procedures in the following sections are for reference only. You are advised to download the Cloud-Init from the official website. The Cloud-init version is updated on the official website in real time. Install the latest version.
When you modify the /etc/cloud/cloud.cfg file, ensure that the file format (such as alignment and spaces) is consistent with the provided example that conforms to the YAML syntax.

Procedure

Take EulerOS 2.2 as an example. Configure the Yum repository of EulerOS 2.2 and edit the /etc/yum.repos.d/EulerOS-base.repo file. For example, the configuration is:
```
[EulerOS-base]
name=EulerOS-base
baseurl=https://repo.huaweicloud.com/euler/2.2/os/x86_64/
enabled=1
gpgcheck=1
gpgkey=https://repo.huaweicloud.com/euler/2.2/os/RPM-GPG-KEY-EulerOS
```
Save the configuration.

Run the following command to update the yum source:

yum repolist

Run the following command to install Cloud-Init 0.7.6:
