Creating persistent volumes

The following steps are a prerequisite to creating the persistent volume manually since we are not using an enterprise storage provisioner such as IBM Spectrum Scale, NetApp, Dell EMC, RedHat Ceph, or Portworx, which will create the persistent volume automatically when a persistent volume claim is made. To create a persistent volume, follow these steps:

1. Create a Consul persistent volumes directory:

$ sudo mkdir -p /var/lib/consul{0,1,2}

2. Create a consul namespace:

$ kubectl create ns consulnamespace/consul created

3. Grant cluster_admin to the consul namespace:

$ kubectl create clusterrolebinding consul-role-binding --clusterrole=cluster-admin --group=system:serviceaccounts:consulclusterrolebinding.rbac.authorization.k8s.io/consul-role-binding ...
