# Playbook to push new microcode. Please read playbook before running.
|
|
#
|
|
# Examples:
|
|
#
|
|
# Update microcode on Overcloud:
|
|
# ansible-playbook -i hosts browbeat/adjust-microcode.yml -e 'get_url_base=http://example.com.com/intel-ucode/'
|
|
#
|
|
# Update microcode on Controllers
|
|
# ansible-playbook -i hosts browbeat/adjust-microcode.yml -e 'target=controller get_url_base=http://example.com.com/intel-ucode/'
|
|
#
|
|
# "target" can be any of the typical groups or a specific host in the hosts file
|
|
# Set get_url_base to the base of a webserver allowing for download of the microcode
