Issues with foreman_hooks plugin

Support
1

Problem: When running a deployment from a discovered host using the foreman_hook scripts i receive the below error in the production.local;

ForemanHooks::Error: Hook failure running `/usr/share/foreman/config/hooks/host/managed/after_build/02-dump-hook-variables.sh after_build rhspesxoc01.domain.com`:

Further error information appears in the after_build.log file that gets created.

Script is simple;

> #/bin/bash
> 
> . $(dirname $0)/hook_functions.sh
> 
> # event name (create, before_destroy etc.)
> # orchestration hooks must obey this to support rollbacks (create/update/destroy)
> event=${HOOK_EVENT}
> 
> # to_s representation of the object, e.g. host's fqdn
> object=${HOOK_OBJECT}
> 
> exec >> /tmp/${event}.log
> exec 2>&1
> 
> system_name=$(hook_data host.host.name)
> system_mac=$(hook_data host.host.mac)
> system_pxe_loader=$(hook_data host.host.pxe_loader)
> system_operatingsystem_name=$(hook_data host.host.operatingsystem_name)
> 
> echo "$(date): received ${event} on ${object}"
> echo "${system_name} ${system_mac} ${system_operatingsystem_name} ${system_pxe_loader}"
> 
> echo "system mac: ${system_mac//:/-}"
> echo "system_name: ${system_name}"
> echo "system_pxe_loader: ${system_pxe_loader}"
> echo "system_operatingsystem_name: ${system_operatingsystem_name}"

Expected outcome: Log file is written with the above details.

Downgrading version of jquery to version jgrep (1.3.3) removed the errors listed under “other relevant data”, however the below still remains and the hook does not run.

/usr/share/foreman/config/hooks/host/managed/after_build/02-dump-hook-variables.sh: 23: /usr/share/foreman/config/hooks/host/managed/after_build/02-dump-hook-variables.sh: Bad substitution

Any assistance is greatly appreciated.

I’ve corrected your pastebins a bit, you were using wrong buttons.

Jgrep is a known issue, you need to make sure it does not get upgraded.

The remaining error looks like a bug in your script, I guess you need to debug this. Capture the JSON and then test your script without Foreman.

Thanks lzap, i ended up just giving up on jgrep and ended up using jq in a shell script to parse the JSON which is working great without any errors.

Thanks for your comment.

Feel free to submit examples into foreman_hooks github repo, jgrep has been problematic due to SCL so something more stable would be great.

:+1: for using jq in the examples.
