Build DHCP enabled Centos Images.md

Overview

This guide talks about how to build centos image to support DHCP IP and import it to PowerVS workspace.

1. Build the image template

   pvsadm image qcow2ova --prep-template-default > image-prep.template
   

2. Add the below lines to end of image-prep.template file to customize network.

    mkdir -p /etc/cloud/cloud.cfg.d
    cat <<EOF >> /etc/cloud/cloud.cfg.d/99-custom-networking.cfg
    network: {config: disabled}
    EOF

3. Build OVA image

   pvsadm image qcow2ova --image-name <name> --image-dist centos --image-url https://cloud.centos.org/centos/8-stream/ppc64le/images/CentOS-Stream-GenericCloud-8-latest.ppc64le.qcow2 --prep-template image-prep.template
   

   Note: Qcow2 CentOS images for ppc64le can be found here

4. Upload image to COS bucket

   pvsadm image upload -b <bucket-name> -f <file-name> -r <region> --accesskey <access-key-value> --secretkey <secret-key-value>
   

5. Import OVA image to a PowerVS Workspace

   pvsadm image import -n <service-instance-name> -b <bucket-name> -o <file-name> -r <region> --accesskey <access-key-value> --secretkey <secret-key-value> --pvs-image-name <final-image-name>
