付録C Building Cloud Images for Red Hat Satellite

Use this section to build and register images to Red Hat Satellite.

You can use a preconfigured Red Hat Enterprise Linux KVM guest QCOW2 image:

These images contain cloud-init. To function properly, they must use ec2-compatible metadata services for provisioning an SSH key.

注記

For the KVM guest images:

The root account in the image is disabled, but sudo access is granted to a special user named cloud-user.
There is no root password set for this image.

The root password is locked in /etc/shadow by placing !! in the second field.

C.1. Creating Custom Red Hat Enterprise Linux Images
リンクのコピー

Prerequisites:

Use a Linux host machine to create an image. In this example, we use a Red Hat Enterprise Linux 7 Workstation.
Use virt-manager on your workstation to complete this procedure. If you create the image on a remote server, connect to the server from your workstation with virt-manager.
A Red Hat Enterprise Linux 7 or 6 ISO file (see Red Hat Enterprise Linux 7.4 Binary DVD or Red Hat Enterprise Linux 6.9 Binary DVD).

For more information about installing a Red Hat Enterprise Linux Workstation, see Red Hat Enterprise Linux 7 Installation Guide.

Before you can create custom images, install the following packages:

Install libvirt, qemu-kvm and graphical tools:

yum install virt-manager virt-viewer libvirt qemu-kvm

[root@host]# yum install virt-manager virt-viewer libvirt qemu-kvm

Toggle word wrap

Install the following command line tools:

yum install virt-install libguestfs-tools-c

[root@host]# yum install virt-install libguestfs-tools-c

Copy to Clipboard

Toggle word wrap

注記

In the following procedures, enter all commands with the [root@host]# prompt on the workstation that hosts the libvirt environment.
