Host Configuration Validation

Trident supports the validate subcommand to validate a Host Configuration YAML file.

Validate a Host Configuration YAML File​

To validate a Host Configuration YAML file offline (eg. in your dev box), use the following command:

trident validate /path/to/host-config.yaml

Online Validation​

To validate a Host Configuration YAML file online (eg. in your target host), you can use a bare invocation to read from /etc/trident/config.yaml, which is the default Host Configuration path:

trident validate

Expected Output​

On successful validation, Trident will exit silently with a zero exit code.

On validation failure, Trident will exit with a non-zero exit code and print the error that caused the validation to fail.

[ERROR trident] Trident failed: Host config is invalid
    
    Caused by:
        0: The block device graph is invalid
        1: Block device 'some_raid' of kind 'raid-array' references non-existent block device 'does-not-exist'
