Kublr Release 1.23.1 (2022-11-10)

Kublr Quick Start

sudo docker run --name kublr -d --restart=unless-stopped -p 9080:9080 kublr/kublr:1.23.1

The Kublr Demo/Installer docker container can be run on ARM-based PC, such as MacBook M1.

Follow the full instructions in Quick start for Kublr Demo/Installer.

The Kublr Demo/Installer is a lightweight, dockerized, limited-functionality with base trial license Kublr Platform which can be used to:

• Test setup and management of a standalone Kubernetes cluster
• Setup a full-featured Kublr Platform
• Trial license use

The Kublr Demo/Installer stores all of the data about the created clusters inside the Docker container. If you delete the Docker container you will lose all data about the created clusters and the Kublr platforms. However, you will not lose the clusters and the platforms themselves.

Known issues and limitations

1. ContainerD CRI does not support private registry authentication; use the following cluster spec configuration override as a workaround if needed:

   kublrAgentConfig:
     kublr:
      containerd:
        config:
          plugins:
            "io.containerd.grpc.v1.cri":
              registry:
                configs:
                  "{{ DOCKER_REPO_URL }}":
                    auth:
                      username: {{ REPO_USER }}
                      password: {{ REPO_PASSWORD }}
                    tls:
                      insecure_skip_verify: true
   

2. For Kublr kubernetes clusters deployed on vSphere it is necessary to unmount CD/DVD drive 1 from each virtual machines manually via vCenter console.

3. vSphere clusters cannot be deleted automaticaly, it is necessary to remove VMs manually and unregister the cluster after that.
