Update the Load Balancer Address

Use these instructions to change your existing load balancer address following a prior installation.

Execute the main installer script again on one of your existing nodes with the new load balancer address specified. The main installer script will generate a new task script that can be executed on the remaining cluster nodes.

To update the TPI load balancer address:

Connect to all the nodes that are part of your Turbine cluster. Note: The update process involves running commands on all cluster nodes. Swimlane recommends having a terminal window/tab open for each SSH session. Open a terminal for each SSH session. # Terminal 1 ssh <node1> # Terminal 2 ssh <node2> # Terminal 3 ssh <node3> ```
On node 1, run the main installer script with the new load balancer address. curl https://kurl.sh/swimlane-platform/install | sudo bash -s ha load-balancer-address=<New LB Address>:6443` Note: If you are on an airgapped deployment, replace the kurl.sh URL withcat install.sh and add the word airgap before ha as in this example: cat install.sh | sudo bash -s airgap ha load-balancer-address=<New LB Address>:6443
The installer script you run on node 1 executes a curl command. Use this new command on the other remote nodes (node 2, node 3). Here is the output from the node 1 installer script: The load balancer address has changed. Run the following on all remote nodes to use the new address: curl -sSL https://kurl.sh/swimlane-platform/tasks.sh | sudo bash -s set-kubeconfig-server <New LB Address>:6443 Continue? (Y/n) Important! Copy the curl command for the next step, but do not enter Y yet.
Run the tasks.sh script on node 2 and node 3. # node 2 [<user>@<node2> ~]$ curl -sSL https://kurl.sh/swimlane-platform/tasks.sh | sudo bash -s set-kubeconfig-server <New LB Address>:6443 Cluster "default-cluster" set. Cluster "kubernetes" set. # node 3 [<user>@<node3> ~]$ curl -sSL https://kurl.sh/swimlane-platform/tasks.sh | sudo bash -s set-kubeconfig-server <New LB Address>:6443 Cluster "default-cluster" set. Cluster "kubernetes" set.
Enter Y to resume the installer load balancer change process on node 1. # node 1 The load balancer address has changed. Run the following on all remote nodes to use the new address: curl -sSL https://kurl.sh/swimlane-platform/tasks.sh | sudo bash -s set-kubeconfig-server <New LB Address>:6443 Continue? (Y/n) Y Removing old load balancer address <Old LB Address> from API server certificate on node <node1> pod/regen-cert-<node1> created Installation Complete ✔ Kotsadm: <New LB Address>:8800 You can log in with your existing password. If you need to reset it, run kubectl kots reset-password default To access the cluster with kubectl, reload your shell: bash -l
Once the installer has finished running, the load balancer address will be updated. Next you update the Turbine application to use the new load balancer address. https://<New LB Address>:8800 >> Login to KOTS UI >> Config >> Update "Swimlane Hostname" with the new LB address >> Save Config >> Deploy Note: If you restore a snapshot from a backup that was generated when the cluster was configured with the old address you will need to update the config again with the new address and deploy (repeat step 6).
