    • Ensure that in a HA cluster the nodes connect to the load balancer for the API server, instead of the first master

  • 0.5.1

    • Each node pool gets its own placement group. This is to minimize issues due to the max 10 nodes limitation for a single node group. A validation has also been added to limit pools to 10 nodes each because of this.

  • 0.5.0

    • Allow installing additional packages when creating the servers
    • Allow enabling ipsec encryption

  • 0.4.9

    • Ensure the program always exits with exit code 1 if the config file fails validation

    • Increase timeout with API requests to 30 seconds

    • Fix network creation (bug introduced in the previous version)

    • Add support for the new Ashburn, Virginia (USA) location
    • Automatically use a placement group so that the instances are all created on different physical hosts for high availability

  • 0.4.3

    • Fix an issue with SSH key creation

  • 0.4.2

    • Update Hetzner CSI driver to v1.6.0
    • Update System Upgrade Controller to v0.8.0

  • 0.4.1

    • Allow to optionally specify the path of the private SSH key
    • Set correct permissions for the kubeconfig file
    • Retry fetching manifests a few times to allow for temporary network issues
    • Allow to optionally schedule workloads on masters
    • Allow clusters with no worker node pools if scheduling is enabled for the masters

  • 0.4.0

    • Ensure the masters are removed from the API load balancer before deleting the load balancer
    • Ensure the servers are removed from the firewall before deleting it
    • Allow using an environment variable to specify the Hetzner token
    • Allow restricting SSH access to the nodes to specific networks
    • Do not open the port 6443 on the nodes if a load balancer is created for an HA cluster

  • 0.3.9

    • Add command "version" to print the version of the tool in use

  • 0.3.8

    • Fix: added a check on a label to ensure that only servers that belong to the cluster are deleted from the project

    • Allow enabling/disabling the host key verification

  • 0.3.0

    • Handle case when an SSH key with the given fingerprint already exists in the Hetzner project
    • Handle a timeout of 5 seconds for requests to the Hetzner API
