OCaml Build Infrastructure

This page is work in progress, by @avsm

There is a hosted machine cluster operated by OCaml Labs that runs regular health checks against the opam package repository, and also runs 'cron' jobs to keep the operational side of things running.

Users can access this information through a variety of mechanisms:

• the opam-ci CLI tool

Packet filter

There is an edgerouter at gw.ocamllabs.io that acts as a router and packet filter for the internal machines. A quick guide to using it is via an ssh terminal is:

$ configure
[edit]
# edit firewall name CL_IN4
[edit firewall name CL_IN4]
# show
[edit firewall name CL_IN4]
# set rule 20 destination address 128.232.124.213
[edit firewall name CL_IN4]
# set rule 20 protocol tcp
[edit firewall name CL_IN4]
# set rule 20 destination port 80,443,8100
[edit firewall name CL_IN4]
# set rule 20 action accept
