This is the Nirmata test script. It will check either your nirmata install, local system for Kubernetes compatiblity, or perform a basic health check of your kubernetes cluster.

The get_logs script will grab logs from the nirmata namespace. See -h for Flags.

See README.kubejobs for making it a K8 cronjob.

The nirmata test script has 3 basic modes: (Yes they should be different scripts, but it's nice to have single script to download for customers in "air gapped" sites.)

Test Nirmata application (default)
./nirmata_test.sh --nirmata

Test local node for Nirmata Agent compatiblity:
./nirmata_test.sh --local

Cluster testing (requires working kubectl config):
./nirmata_test.sh --cluster

There are also a host of other features such as email support, and ssh support. See --help for more info.

Examples:
Run local tests on remote host.
./nirmata_test.sh --local --ssh "[email protected] [email protected]"

Email on error (Note using gmail requires an app password)
./nirmata_test.sh --cluster --email --to [email protected] --smtp smtp.gmail.com:587 --user sam.silbory --passwd 'foo!foo'

Return codes are as follows:
0 Good
1 Error
2 Warning
