RHEL for edge

Build ISO for edge devices

• prepare host with RHEL8.4+ - 2 CPUs, 4GB memory and 20GB of storage. It may be a VM, CNV VM or physical appliance. Web server running must be reachable by edge devices.
• use a user with sudo - make sure user does not need to enter password each time (set NOPASSWD in sudoers file)
• make sure selinux is running in permissive mode
• register the system

  sudo subscription-manager register --username <redhat_login_username> --password <redhat_login_password> --auto-attach
  

• clone or download this repository to the RHEL host
• download RHEL boot ISO to root folder of the repository
• make sure there is yum repo availabe with yggdrasil and device-worker
• create repo.toml pointing to above repo

  id = "agent"
  name = "agent"
  type = "yum-baseurl"
  url = "<repo-url>"
  check_gpg = false
  check_ssl = false
  system = false
  

• execute r4e-setup.sh
• add the repo as composer source by running;

  composer-cli sources add repo.toml
  

• execute r4e-iso.sh
• test that new image is ready:
  • browse to

    http://<host-ip>/<image-name>
    

    you should see a listing of the image directory:

    - ISO file
    - kickstart file
