Research Computing OpenOnDemand Message
Note: the rules below are based on OOD 1.6. We might have to review the rules when we upgrade to newer version of OOD.
In order to track all the announcements we have made, we create this repo to track all the changes. In the repo, there are two files:
- motd
- announcement.md
motd
This will add Message of the Day section in OOD Dashboard.
In OOD, you can have motd in different format and we have set it to MOTD_FORMAT="markdown". Therefore, you can have markdown syntax in this file.
announcement
This will add an announcement message that appears at the top of the OOD Dashboard.
We currently have the file end with .md so it will be converted using a markdown converter.
If the announcement file has the extension yml and is a yaml file it is first rendered using ERB and then the resulting file is parsed as YAML. The valid keys are:
| YAML key | Description | Note |
|---|---|---|
| type | warning, info, success, or danger | this is the Bootstrap alert style |
| msg | string containing markdown formatted message | if this is a blank string (only whitespace), the alert will not display |
Because it is rendered via ERB you can do some interesting things, like stop showing the announcement past a specified date:
type: warning
msg: |
<% if Time.now < Time.new(2018, 9, 24, 12, 0, 0) %>
A **Ruby Partial Downtime** for 4 hours on Monday, September 24 from 8:00am to 12:00pm
will prevent SSH login to Ruby nodes and and Ruby VDI sessions.
