Comprobación de la configuración del host

Después de crear hosts que cumplan requisitos del sistema, requisitos de red y requisitos de conectividad salientes, puede verificar la configuración del host ejecutando el siguiente script sat-host-check.

Inicie una sesión en el host.

ssh root@<IP_address>

Para hosts RHEL, SSH como root.
```
ssh root@<IP_address>
```

Para los hosts RHCOS, copie la clave SSH pública en el script de encendido e inicie sesión como núcleo.

Descargue el script de conexión de host y añada la clave SSH pública.

{
  "ignition": {
    "version": "3.1.0"
  },
  "passwd": {
    "users": [
      {
        "name": "core",
        "sshAuthorizedKeys": [ "PUBLIC-SSH-KEY" ]
      }
    ]
  },
...
}

Inicie sesión en el host como core.
```
ssh core@<IP_address>
```

Descargue el script y haga que sea ejecutable.

curl https://origin.<region>.containers.cloud.ibm.com/satellite-health/sat-host-check -o sat-host-check && chmod +x sat-host-check

Mandato de ejemplo para us-south.

curl https://origin.us-south.containers.cloud.ibm.com/satellite-health/sat-host-check -o sat-host-check && chmod +x sat-host-check

Ejecute el script y especifique la región donde ha creado la ubicación.

sudo ./sat-host-check --region $REGION

Mandato de ejemplo para us-south.

sudo ./sat-host-check --region us-south

Salida de ejemplo para comprobar un host en us-south.

Revise el resumen de anomalías de prueba. En función de la anomalía, revise los requisitos y actualice los hosts.
- Requisitos del sistema host
- Requisitos de almacenamiento de host
- Requisitos de red de host
- Requisitos de conectividad de salida host y los requisitos de conectividad de salida específicos de la región para la región en la que ha creado la ubicación.
Si la comprobación del host es satisfactoria, puede continuar conectando el host a la ubicación.
