6.2. Deploying a container image from the network by using Anaconda and Kickstart

Procedure

1. Create an ostreecontainer Kickstart file to fetch the image from the network. For example:

   # Basic setup
   text
   network --bootproto=dhcp --device=link --activate
   # Basic partitioning
   clearpart --all --initlabel --disklabel=gpt
   reqpart --add-boot
   part / --grow --fstype xfs
   
   # Reference the container image to install - The kickstart
   # has no %packages section. A container image is being installed.
   ostreecontainer --url quay.io/<namespace>/<image>:<tag> . bootc-image-builder:latest
   
   firewall --disabled
   services --enabled=sshd
   
   # Only inject a SSH key for root
   rootpw --iscrypted locked
   sshkey --username root "<your-key>"
   reboot

2. Boot a system by using the RHEL 10 Boot ISO installation media.

   1. Append the Kickstart file with the following to the kernel argument:

      inst.ks=http://<path_to_your_kickstart>

3. Press CTRL+X to boot the system.
