Some hints and alternative configurations for the docker instance running the checks.
Instead of starting and closing a docker instance for every check, one can also start the instance once and send the checks to it:
docker load -i check_netapp_pro.tar.gz (this is the same for run.sh and exec.sh)
Start an instance of the container with name netapp_checks and restart-policy always:
docker run \
--network=host \
-v /usr/local/check_netapp_pro/var/store:/usr/local/check_netapp_pro/var/store\
-v /usr/local/check_netapp_pro/etc:/usr/local/check_netapp_pro/etc \
--name netapp_checks \
--tty \
--restart always \
--detach \
check_netapp_pro
This configuration will start the docker-instance netapp_checks together with the docker-service. This instance will then run the checks sent to it with docker exec.
Instead of run.sh you must use exec.sh with the following content:
#!/bin/bash
docker exec --tty netapp_checks $@
