Removing the agent from an edge cluster

To unregister an edge cluster and remove the Open Horizon agent from that cluster, perform these steps:

1. Extract the agent-uninstall.sh script from the tar file:

   tar -zxvf agentInstallFiles-x86_64-Cluster.tar.gz agent-uninstall.sh
   

2. Export your Horizon exchange user credentials:

   export HZN_ORG_ID=<your-exchange-organization>
   export HZN_EXCHANGE_USER_AUTH=<authentication string>
   export HZN_EXCHANGE_URL= # example http://open-horizon.lfedge.iol.unh.edu:3090/v1
   export HZN_FSS_CSSURL= # example http://open-horizon.lfedge.iol.unh.edu:9443/
   export HZN_AGBOT_URL= # example http://open-horizon.lfedge.iol.unh.edu:3111
   export HZN_FDO_SVC_URL= # example http://open-horizon.lfedge.iol.unh.edu:9008/api
   

3. Remove the agent:

   ./agent-uninstall.sh -u $HZN_EXCHANGE_USER_AUTH -d
   

Note: Occasionally, deleting the namespace stalls in the “Terminating” state. In this situation, see A namespace is stuck in the Terminating state to manually delete namespace.
