Accessing Data Hub cluster via SSH

You can use SSH to access cluster nodes via a command line client.


Method	Credentials
Root SSH access to cluster VMs	Required role: None CDP administrators can access cluster nodes as `cloudbreak` user with the SSH key provided during environment creation. On Mac OS, you can use the following syntax to SSH to the VM: `ssh -i "privatekey.pem" cloudbreak@publicIP` For example: `ssh -i "testkey-kp.pem" cloudbreak@p90.101.0.132` On Windows, you can access your cluster via SSH by using an SSH client such as PuTTY. For more information, refer to How to use PuTTY on Windows.
Non-root SSH access to cluster VMs	Required role: Any user who has access to the environment (EnvironmentUser, DataSteward, and EnvironmentAdmin) can access Data Hubs via SSH. All authorized users can access cluster nodes via SSH using either a private key that is paired with the user's public key, or with their workload user name and workload password. For SSH access through a workload user name and password: When accessing CDP for the first time, you must set a workload password. The password also needs to be reset each time you are added to a new environment. For more information about workload passwords and instructions for setting/resetting it, refer to Set or Reset Workload Password. For instructions on how to find your workload user name, refer to Finding Your Workload User Name. On Mac OS, you can use the following syntax to SSH to the VM: `$ ssh workload-user@publicIP` For example: `$ ssh jsmith@190.101.0.132` To SSH to a cluster using the private key file that pairs with the public key associated with a user, use the `ssh` utility: `$ ssh -i path-to-private-key-file user@nodeIPaddress` For example: `$ ssh -i ~/.ssh/my-private.key jsmith@192.12.141.12` On Windows, you can access your cluster via SSH by using an SSH client such as PuTTY. For more information, refer to How to use PuTTY on Windows.
