Hi, In our undercloud director we created a yum repository and put any new updates in here.We like to update the overcloud(compute so on) from here using yum over port 21(ftp). Is this approach good? or i should use https://tripleo-docs.readthedocs.io/en/latest/post_deployment/package_update.html (https://tripleo-docs.readthedocs.io/e...) Give me an yml file example to install or upgrade curl package. it is urgent.
