Implement a ConsoleConnection resource that verifies serial console connectivity to devices via SSH console servers. The controller supports three verification strategies (Wait, SendCRLF, SendChar) and reports five health states: ConsoleServerUnreachable, ConsoleServerAuthFailure, Dead, Alive, and Verified. Includes envtest integration tests with an in-process SSH server, sample manifests for all verification strategies, and Tiltfile integration. Signed-off-by: Felix Kästner <felix.kaestner@sap.com>
The rustfs/rc image does not resolve short service names via the pod DNS search domains. Use the full cluster-local FQDN to ensure reliable DNS resolution. Signed-off-by: Felix Kästner <felix.kaestner@sap.com>
When nslookup fails to resolve host.docker.internal, the only 'Address:' line in the output is the DNS server itself. This was concatenated with ':9339', producing an invalid device endpoint address. Filter out lines containing :53 so a failed lookup yields an empty result, keeping the sample's original address unchanged. Signed-off-by: Felix Kästner <felix.kaestner@sap.com>
