In-cluster Redis High Availability Add-on configuration​

Checking Redis HAA license status​

kubectl get rec -n redis-system redis-cluster -o jsonpath='{.status.licenseStatus}' | jq
kubectl get rec -n redis-system redis-cluster -o jsonpath='{.status.licenseStatus}' | jq

• Clusters deployed after the expiry date of the license included in the installer will show the trial 4-shard license that expires in 30 days, as in the following example:

  

• Clusters that were already running when the license expired will show the following status:

  

Adding or updating the Redis HAA license​

1. Purchase an HAA license. Contact UiPath® for details.

2. Update the following fields in the cluster_config.json file:

   • fabric.redis.license - enter the HAA license converted to a single base64 string. You need to encode the entire license key to base64, including the text -----LICENSE START----- and -----LICENSE END-----. In bash, you can do that using the following command:
     assignment

     echo '-----LICENSE START-----<license_key_here>-----LICENSE END-----' | base64 -w0
     echo '-----LICENSE START-----<license_key_here>-----LICENSE END-----' | base64 -w0
     

   • fabric.redis.ha - use true to enable HAA and make sure to also configure the fabric.redis.license parameter. This enables HAA database replication and increases the number of HAA pods to 3. By default, fabric.redis.ha is set to false.
     Note:

     If redis.ha is enabled, redis.license needs to be set to a license that supports more than two shards.

     assignment

     "fabric": {
         "redis": { 
             "ha": "true",
             "license": "Base64String" // Replace Base64String with the encoded full license string.
         }
     }
     "fabric": {
         "redis": { 
             "ha": "true",
             "license": "Base64String" // Replace Base64String with the encoded full license string.
         }
     }
     

3. Rerun the installer:

   assignment

   ./bin/uipathctl manifest apply /opt/UiPathAutomationSuite/cluster_config.json --versions versions/helm-charts.json
   ./bin/uipathctl manifest apply /opt/UiPathAutomationSuite/cluster_config.json --versions versions/helm-charts.json
