Kubeopsctl-2.0: Single Sign-On with Keycloak

Mon, 01 Jan 0001 00:00:00 +0000

In this guide, you will learn how to implement Single Sign-On (SSO) using Keycloak. We will walk through the complete flow—from understanding SSO for platforms and services such as Rook Ceph, Harbor, and other Kubernetes applications, to configuring Keycloak, exposing it securely, and integrating it with kubeops.

By the end of this guide, you will be able to:

Understand how Keycloak enables centralized authentication
Configure Keycloak for SSO
Securely expose Keycloak using Kubernetes Ingress and TLS
Integrate Keycloak with kubeops for authentication and authorization
Validate and troubleshoot the SSO login flow

Let’s get started on enabling secure and seamless authentication with Keycloak.

Kubeopsctl: How to set up SSH keys

Mon, 01 Jan 0001 00:00:00 +0000

To securely access the kubeops master and worker machines, you need to create a ssh-key-pair (private and public key) on the admin machine. Afterwards copy the public key onto each machine.

Install SSH Client

Most Linux distributions come with an SSH client pre-installed. If its not installed, you can install it using your distributions package manager.

Important For installing new additional software you may need permissions (e.g. root or sudo).

For RHEL8 OS use following command.

sudo dnf install -y openssh-client

Generate SSH Keys

If you do not already have an SSH key or if you want to generate a new key pair specifically for this connection, follow these steps.

Run the command

ssh-keygen

Follow the prompts to choose a file location and passphrase (optional but recommended for added security).

Copy the Public Key to the Remote Machine

To avoid password prompts every time you connect, you can authorize your public key on the remote machine.

You can manually copy the public key to the servers authorized keys using the command ssh-copy-id.

ssh-copy-id <username>@<remote_host>

Replace <username>@<remote_host> with your actual username and the remote machine‘s IP address or hostname.

If ssh-copy-id is not available, you can use the following command:

cat ~/.ssh/id_rsa.pub | ssh username@remote_host "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

Additional Information

For more information about commands see the documentation of your respective operating system.

For ssh or ssh-keygen you can use the manual pages:

man ssh

man ssh-keygen
