[SOLVED] command exited with status: 1

[GadgetChris]

I just upgraded to docker version 1.36.33 from 1.36.32 to see if this fixed my issue, but to no avail.

I have a folder:

Code: Select all

root@023c028759ee:/# ls -l /var/www/scripts/
total 8
-rwxrwxr-x 1 1000 1000 118 Mar 12 22:48 trigger.sh
-rwxrwxr-x 1 1000 1000  32 Mar 12 23:08 zm-approach
-rw-rw-r-- 1 1000 1000   0 Mar 11 00:37 zm-package

And I can manually run successfully:

Code: Select all

root@e59f8d6fac75:/# zmfilter.pl --filter "trigger approach"
03/12/24 23:08:37.748207 zmfilter[822468].INF [main:179] [Scanning for events using filter 'trigger approach']
03/12/24 23:08:37.873674 zmfilter[822468].INF [main:1061] [Executing '/var/www/scripts/trigger.sh zm-approach /data/events/2/2024-03-11/20345']
03/12/24 23:08:37.880845 zmfilter[822468].INF [main:1061] [Executing '/var/www/scripts/trigger.sh zm-approach /data/events/2/2024-03-11/20347']

The trigger script will just put the event data in a file within the script directory:

Code: Select all

root@023c028759ee:/# cat /var/www/scripts/trigger.sh 
#!/bin/bash
#--- create a trigger for host processing
#set -x
#source ~/.bash_trace

cd /var/www/scripts
echo $2 > $1

In my filter I define for action the command execution:

Code: Select all

Execute command on all matches[b]:[/b]
/var/www/scripts/trigger.sh zm-approach

in the logs I see:

Code: Select all

3/12/24, 11:58:43 PM EDT	zmfilter_6		529	ERR	Command '/var/www/scripts/trigger.sh zm-package /data/events/2/2024-03-12/20575' exited with status: 1

What does this error mean?
And how can I succeed in getting the file created...

( On the host I have scripts waiting to further take action on the creation of this file...)

Thank you, Chris

p.s. Why can I not enter a colon in the text?

Can www-data use those? Looks like they're root.

Your script has to get return a value of 0 for success. You don't explicitly set a return value, so it will be whatever the return value of the last line is. In the case echo $2 > $1?

Thank you, that makes sense.

I'm still not sure it's working, due to filled up logs. Will open a separate thread for that.

While running in a docker container, there is no syslog logs to check for permission failures - that I have found thus far.
After explicitly setting the owner to www-data the trigger started to fire:

Code: Select all

root@023c028759ee:/# chown www-data /var/www/scripts/*
root@023c028759ee:/# ls -l /var/www/scripts/
total 12
-rwxrwxr-x 1 www-data 1000 125 Mar 13 10:50 trigger.sh
-rwxrwxr-x 1 www-data 1000  32 Mar 12 23:08 zm-approach
-rw-rw-r-- 1 www-data 1000  32 Mar 16 09:48 zm-package

Thank you for your help.
