"Upgrade ironic DB Schema" fails during bifrost deploy

"Upgrade ironic DB Schema" fails at "ironic-dbsync upgrade --config-file /etc/ironic/ironic.conf" with a file not found error. This is caused by the ironic-dbsync executable not being installed. Solution - Install ironic packages into the container:

yum install openstack-ironic-common openstack-ironic-api openstack-ironic-conductor

PXE/iPXE (pxelinux.0/undionly.kpxe) missing during bifrost deploy

Follow the guide at [3] to install and configure PXE/iPXE.

nginx is missing during bifrost deploy

Install nginx:

yum install nginx

SELinux related tasks failing due to SELinux being disabled in the bifrost deploy container

Symptoms:

Solution:

Edit

vi /bifrost-base-source/bifrost-4.0.0/playbooks/roles/bifrost-ironic-install/tasks/bootstrap.yml

Comment out or remove the following block:

- block:
    - name: "Explicitly allow nginx and IPA port (TCP) on selinux"
      seport:
        ports: "{{ file_url_port }},6385"

      command: semanage fcontext -a -t httpd_sys_content_t "{{ http_boot_folder }}(/.*)?"

    - name: Copy ironic policy file to temporary directory
      copy:
        src: ironic_policy.te
        dest: /tmp/ironic_policy.te

    - name: Check ironic policy module

    - name: Package ironic policy module

Solution: Install diskimage-builder

yum install diskimage-builder

Note: Make sure

dib_os_element: centos7

is set in

/etc/bifrost/dib.yml

instead of

dib_os_element: centos

Otherwise the following failure may occur:
