Docker container does not trigger script

[prevostc]

I use the script from the documentation (located in /var/www/lovebeat.sh):

#!/bin/bash

echo "Hello World"
env

And this config file (located in /var/www/lovebeat.sh):

[[alarms]]
name = "beatstash"
pattern = "beatstash.*"
[[alarms.alerts]]
script = "/var/www/lovebeat.sh"

Along with this docker command:

docker run --rm -it -p 8127:8127/udp -p 8127:8127/tcp -p 8082:8080 -v /etc/lovebeat.cfg:/etc/lovebeat.cfg -v /var/log/lovebeat:/var/log/lovebeat/ -v /var/www/lovebeat.sh:/var/www/lovebeat.sh boivie/lovebeat

And then when I send some events with an error timeout of 1 second, the script is not called:

$ docker run --rm -it -p 8127:8127/udp -p 8127:8127/tcp -p 8082:8080 -v /etc/lovebeat.cfg:/etc/lovebeat.cfg -v /var/log/lovebeat:/var/log/lovebeat/ -v /var/www/lovebeat.sh:/var/www/lovebeat.sh boivie/lovebeat

Logs from event-sender terminal (on the same machine):

$ curl -X POST -H 'application/x-www-form-urlencoded' 'http://localhost:8082/api/services/beatstash.heartbeat?err-tmo=1'
{}
$ # sleep 5 seconds
$ curl -X POST -H 'application/x-www-form-urlencoded' 'http://localhost:8082/api/services/beatstash.heartbeat?err-tmo=1'
{}

According to the documentation I should see something like this in the output logs:

2016/01/26 18:10:56 INFO ALARM 'example', 11: state ok -> error
2016/01/26 18:10:56 INFO Running alert script /path/to/script.sh
Hello World
LOVEBEAT_ALARM=example
LOVEBEAT_STATE=ERROR
LOVEBEAT_PREVIOUS_STATE=OK
LOVEBEAT_INCIDENT=11

But it's not the case.

I also checked script permissions and it's 0777 for now :

$ ls -la /var/www/lovebeat.sh 
-rwxrwxrwx 1 root root 35 Jul 12 14:25 /var/www/lovebeat.sh
$ /var/www/lovebeat.sh 
Hello World
LC_PAPER=en_US.UTF-8
LC_ADDRESS=en_US.UTF-8
[...] more env [...]

I see that the docker image hasn't been updated to the version that supports this. It's still on 0.8, while we have released 1.0 now.

I'll do that this evening.

Sorry about that. The binaries found in Github's releases are up to date, though.

Ok, noted, thanks.

Can you take a look at http://lovebeat.readthedocs.io/, I think this doc is outdated too.

[boivie]

I've updated the docker images now.

Could you please tell me what's outdated in the docs and I'll update it

The alerter configuration example does not work: http://lovebeat.readthedocs.io/en/latest/alerters.html

For script alerter it states:

[[alarms]]
name = "example"
pattern = "test.*"
alerts = ["test-alert"]

[[alarms.alerts]]
script = "/path/to/script.sh"

Which triggers an error.

The documentation in master is up to date but readthedocs.io isn't.
