Very simple program that can run some nagios plugins on a schedule and notify to slack when their state change.

The program is configured solely through environment variables:

To set up a check export:

SLAGIOS_check_<check_name>=<check_comand>

where <check_name> could be something like "01" for the first check, "02" for the second etc. But <check_name> can be any string as long as it unique to a check.

Optionally set the check and recheck interval for a check:

SLAGIOS_interval_<check_name>=<check_interval>
SLAGIOS_rinterval_<check_name>=<check_interval>

Use the same <check_name> as for the check command you want to change.

The default check interval is 60s, but this can be changed by setting:

SLAGIOS_interval=<check_interval>

The default recheck interval is 60s, but this can be changed by setting:

SLAGIOS_rinterval=<check_interval>

<check_interval> is in nano seconds, but takes any string parseable by go's time.ParseDuration function. Eg. 30s, 1min etc.

A Slack webhook URL is required if you want to send state changes to Slack:

SLAGIOS_webhook=<url>

To enable a slash command create a slash command in a Slack App to <slash_cmd>, point i to the exposed port (port 80 internally), and set the following environment variable with you Slack App signing key key:

SLAGIOS_signingkey=<signing_secret>
SLAGIOS_slashcmd=<slash_cmd>

To run the docker image create a file containing environment variables as described above, and run:

docker run --name slagios --rm --env-file env -p 8000:80 jbros/slagios

To build the docker image:

docker build -t jbros/slagios .
