Welcome! This is the Fedora Infrastructure Ansible Pagure project.
Pull requests and forks can be made against this repository hosted at https://pagure.io/fedora-infra/ansible
This repository is also mirrored for production runs to https://infrastructure.fedoraproject.org/infra/ansible/ but this is the working repository where changes are made.
If you would like to help out with Fedora Infrastructure, see:
- https://docs.fedoraproject.org/en-US/infra/gettingstarted/

files - files and templates for use in playbooks/tasks
- subdirs for specific tasks/dirs highly recommended
inventory - where the inventory and additional vars is stored
- All files in this directory in ini format
- added together for total inventory
group_vars:
- per group variables set here in a file per group
host_vars:
- per host variables set here in a file per host
library - library of custom local ansible modules
playbooks - collections of plays we want to run on systems
groups: groups of hosts configured from one playbook.
hosts: playbooks for single hosts.
manual: playbooks that are only run manually by an admin as needed.
tasks - snippets of tasks that should be included in plays
roles - specific roles to be use in playbooks.
Each role has it's own files/templates/vars
filter_plugins - Jinja filters
main.yml - This is the main playbook, consisting of all
current group and host playbooks. Note that the
daily cron doesn't run this, it runs even over
playbooks that are not yet included in main.
This playbook is usefull for making changes over
multiple groups/hosts usually with -t (tag).
The public path on batcave01 (our control host) for everything is /srv/web/infra/ansible
The private path on batcave01 (our control host) (which is sysadmin-main accessible only)
is /srv/private/ansible
In general to run any ansible playbook you will want to run:
sudo -i ansible-playbook /path/to/playbook.yml
(On batcave01, our control host)
Every night a cron job runs over all playbooks under playbooks/{groups}{hosts}
with ansible --check --diff. A report from this is sent to sysadmin-logs.
In the ideal state this report would be empty.
All playbooks should be idempotent. Ie, if run once they should bring the machine(s) to the desired state, and if run again N times after that they should make 0 changes (because the machine(s) are in the desired state). Please make sure your playbooks are idempotent.
When a playbook or change is checked into ansible you should assume that it could be run at ANY TIME. Always make sure the checked in state is the desired state. Always test changes when they land so they don't surprise you later.

If found a way to improve this repository or fix an issue found in our infrastructure tracker (see https://pagure.io/fedora-infrastructure/issues) open a pull-request.
You either should have capability to run the playbooks after they have been reviewed, and merged or find the person responsible and work with them to make sure the changes will be aplied afterwards.
We are currently working on a simple to use list of Point Of Contanct people for the applications here, untill it is done, you can, look at people that recently edited the ansible files, or if you belong to sysadmin group, view the /etc/ansible_utils/rbac.yaml located on batcave01, where you can see the groups of people that have capabilities to run the relevant playbooks.
For example, to upgrade Release Monitoring, you need to run playbook openshift-apps/release-monitoring.yaml. People in sysadmin-releasemonitoring have that capability, and you cand find the members in https://accounts.fedoraproject.org/group/sysadmin-releasemonitoring/
If the application in question is not on the critical path it should be sufficient, if person responsible for the application reviews the PR.
If the files in question are on the critical path, that are necessary for functioning packager workflow, at least two different people should review the PR.
If there is any risk at all, that the application of the changes would induce downtime, work closely with other to ensure that the downtime is properly scheduled:
- there is an issue in https://pagure.io/fedora-infrastructure/issues specifying the downtime
- there is an email sent to the devel-list
- https://status.fedoraproject.org is updated (see https://docs.fedoraproject.org/en-US/infra/sysadmin_guide/status-fedora/)
