Removing an IBM Cloud Private cluster node

Remove a cluster node from your IBM® Cloud Private cluster.

1. Change to the cluster directory within your IBM Cloud Private installation directory:

    cd /<installation_directory>/cluster
   

2. If you want to remove a a IBM® Z worker node from your cluster, the /<installation_directory>/cluster/images folder must contain the ibm-cloud-private-s390x-3.1.1.tar.gz file.

3. To remove a node, run the following command:

    docker run -e LICENSE=accept --net=host \
    -v "$(pwd)":/installer/cluster \
    ibmcom/icp-inception-$(uname -m | sed 's/x86_64/amd64/g'):3.1.1-ee uninstall -l \
    ip_address_clusternode1,ip_address_clusternode2
   

   In this command, ip_address_clusternode1 and ip_address_clusternode2 are IP addresses of nodes that are listed in the hosts file. These nodes can be a combination of worker, proxy, or management nodes.
