Post-Backup/Failure Hooks

[Jacksaur]

I saw the container has built-in support for healthchecks, which is great. But the mechanism of course, will only alert if the entire container goes down.
It'd be great if we could define commands to be executed on Backup completion, or failure, such that I can trigger Healthchecks alerts depending on the actual state of the backup process.

That isn't true. The logic is defined here:

pbs-client-docker/docker/src/s6-services/backup/run_include

Lines 70 to 80 in 5ac6cac

	# Run the actual backup command.
	${BACKUPCMD} 2>&1
	BACKUP_EXIT_CODE=$?
	# First run touches the file. Backups will set the date.
	echo "$(date +"%Y-%m-%d %H:%M:%S")" > "${lastrunfile}"
	if [ -n "$HEALTHCHECKSURL" ]; then
	# We pipe the exit code to healthchecks, if it isn't zero, a warning will fire.
	curl -fsS -m 10 --retry 5 -o /dev/null ${HEALTHCHECKSURL}/${BACKUP_EXIT_CODE}
	fi

It already reflects the status of the attempt to do a backup, with any error fed directly to healthchecks.

Aaah, thanks.
I only saw the environment variable in .env file, so I assumed it was the standard healthchecks feature that's bundled into some containers. Not an actual part of the backup script.

Cheers.

Please let me know if this doesn't clear things up, I will close this conversation shortly unless this isn't the case.

Thanks!

Did some testing and troubleshooting:
s6-services/setup-check/run_include sets the HC URL to ${HEALTHCHECKSHOSTNAME}/ping/${HEALTHCHECKSUUID}. However, the healthchecks.io website uses just ${HEALTHCHECKSHOSTNAME}/${HEALTHCHECKSUUID} as its address for pings, so the curl attempt fails with a 400 - Invalid URL Format response.
Is that /ping/ required for the selfhosted version of Healthchecks?

Would it be possible to add a variable to support the healthchecks.io website, by removing the /ping from the URL?
