How to create credentials for Jupyterhub?

Question

I have provisioned a Spark 2.3.1 notebooks & Jupyterhub with SSL & centos7x cluster on BlueData.

When I access the Jupyerhub service, I am prompted for a username and password:

My BlueData Tenant:

• is NOT configured for LDAP/AD
• has Cluster Superuser Privilege set to Site Admin and Tenant Member/Admin

How can I generate a static username/password credentials for accessing Jupyterhub?

Answer 1

First login to the tenant and then navigate to the clusters screen.

Click the link to download the Tenant KeyPair:

Now, click on the link for the cluster (in my example this is 'test'):

You can retrieve the jupyterhub ssh hostname and port. Remember to change the hostname to the gateway hostname. You can now ssh into the cluster:

ssh bluedata@your_gw_host -p your_port -i /downloaded/tenant/keypair.pem

You can add a user as follows:

sudo useradd your_username

# set the password for your_username
sudo passwd your_username

You can now login to Jupyterhub with those credentials.
