| title: System tooling overview | ||
| --- | ||
|
|
||
| For new members of the team who might be unfamiliar with Cloud Foundry, BOSH, Concourse/fly and a multi-repository configuration, there are many familiar aspects of the system, especially system tooling, that might well be difficult to discover. This document presents a simple overview of common system tooling elements used in Cloud.gov operations and how they're implemented in the context of our BOSH/Cloud Foundry architecture. |

👏 We can definitely add more to this section and general docs as time goes on.

@datn brought this up at standup, and it's good to merge in. This story is a micro task from the greater cloud-gov/cg-atlas#125. |

| To keep system clock time accurate, the Cloud.gov operations BOSH deployment installs a `cron` job on each host for the root user which runs `ntpdate` every 15 minutes. | ||
|
|
||
| From the `cg-deploy-bosh` repository, the global NTP configuration is defined in the `agent` section of the BOSH deployment manifests and ends up on each host in `/var/vcap/bosh/etc/ntpserver`, used in turn by the `ntpdate` script from the [bosh_ntpdate](https://github.com/cloudfoundry/bosh/tree/master/stemcell_builder/stages/bosh_ntpdate) stage of the BOSH stemcell builder. |

Awesome. I don't think this was easily discovered before without looking at the Bosh source. 👍

I'm walking a fine line as regards the level of detail to include, and I anticipate much opinion and critique of this document, but here is a start with the fruits of my labors on my last two stories.
