Facts usage Example and testing

[Steve Pribyl]

Could someone provide a code example for checking facts in a kickstart.erb file?   I am not sure I am use the right syntax. 

Also is it possible to wget a file from razor as part of a development testing step?
I would like to see what files are getting generated and check for errors, doing so during an osinstall gets complicated. 

e.g.

wget https://razor/<something>/kickstart.cfg?<arg>&<arg> 

Thanks

I don't actually access any Facter facts currently in my kickstart.erb
file, but I think the syntax would be something like this:

node.facts['bios_release_date']

I believe you should be able to access any of the sources of information
listed when you run:

razor nodes $node-number | grep 'additional details'

So, that'd be these sources of information:

[facts, hw_info, log, metadata, policy, state, tags]

For example, I use a kickstart variable in my kickstart.erb:

partition_type="<%= node.metadata['partition_type'] %>"
if [ "$partition_type" == "small" ]; then
...
fi

partition_type is a custom variable that's part of the node's metadata
that we set manually:

razor update-node-metadata node12 partition_type small

Hi Steve,

Brian got the first part `<%= node.facts['key'] %>`. The second you can hit a number of endpoints below (caveat: these are not part of the API, so could be subject to change... however unlikely that may seem):

*Note: ## should just be the node number, e.g. "5" for "node5".

- Rendered task files: https://razor:8150/svc/file/##/kickstart

- Raw task files (not for .erb files): https://razor:8150/svc/file/raw/${filename}

- Repo files: https://razor:8150/svc/repo/${repo_name}/${filepath}

- Rendered broker files: https://razor:8150/svc/broker/##/install (append `?script=install.ps1` for e.g. Windows machines)

Hope that helps,

Scott

Thanks all this helps, I had a syntax error in my code from not understanding. 

<%= is assignment

<% is code  

Also thanks for the URL hints, that helps a great deal.
