To set up Swift:

1. Create and rebalance the Swift ring manually.

   You can use the following example configuration scripts as the basis for your Swift ring configuration.

   The scripts create the following required files in the /etc/kolla/config/swift directory on the master node:

   • account.builder

   • account.ring.gz

   • container.builder

   • container.ring.gz

   • object.builder

   • object.ring.gz

   Example 4.1 Swift multinode ring configuration script

   The following script is an example of setting up the Swift ring for a multinode deployment. The example uses a three-node storage array.

   The REGISTRY and TAG variables use the Kolla properties that contain the location and port of your OpenStack Docker registry and the OpenStack release number.

   Set the IP address for each storage node using the node_IP option in the STORAGE array at the start of the script, for example, STORAGE[1]=10.0.0.10.

   #!/usr/bin/env bash
   
   REGISTRY=registry_hostname:registry_port
   TAG=openstack_release
   
   STORAGE[1]=node_IP
   STORAGE[2]=node_IP
   STORAGE[3]=node_IP
   
   # Note: In this example, each storage node is placed in its own zone
   
   # Object ring
   docker run --rm \
     -v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
     ${REGISTRY}/oracle/ol-openstack-swift-base:${TAG} \
     swift-ring-builder /etc/kolla/config/swift/object.builder create 10 3 1
   
   for NODE in 1 2 3; do
     echo "object.builder: Adding ${STORAGE[$NODE]} to zone z${NODE}"
     docker run --rm \
       -v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
       ${REGISTRY}/oracle/ol-openstack-swift-base:${TAG} swift-ring-builder \
       /etc/kolla/config/swift/object.builder add z${NODE}-${STORAGE[$NODE]}:6000/sdb1 1
   done
   
   # Account ring
   docker run --rm \
     -v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
     ${REGISTRY}/oracle/ol-openstack-swift-base:${TAG} \
     swift-ring-builder /etc/kolla/config/swift/account.builder create 10 3 1
   
   for NODE in 1 2 3; do
     echo "account.builder: Adding ${STORAGE[$NODE]} to zone z${NODE}"
     docker run --rm \
       -v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
       ${REGISTRY}/oracle/ol-openstack-swift-base:${TAG} swift-ring-builder \
       /etc/kolla/config/swift/account.builder add z${NODE}-${STORAGE[$NODE]}:6001/sdb1 1
   done
   
   # Container ring
   docker run --rm \
     -v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
     ${REGISTRY}/oracle/ol-openstack-swift-base:${TAG} \
     swift-ring-builder /etc/kolla/config/swift/container.builder create 10 3 1
   
   for NODE in 1 2 3; do
     echo "container.builder: Adding ${STORAGE[$NODE]} to zone z${NODE}"
     docker run --rm \
       -v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
       ${REGISTRY}/oracle/ol-openstack-swift-base:${TAG} swift-ring-builder \
       /etc/kolla/config/swift/container.builder add z${NODE}-${STORAGE[$NODE]}:6002/sdb1 1
   done
   
   for ring in object account container; do
     docker run --rm \
       -v /etc/kolla/config/swift/:/etc/kolla/config/swift/ \
       ${REGISTRY}/oracle/ol-openstack-swift-base:${TAG} swift-ring-builder \
       /etc/kolla/config/swift/${ring}.builder rebalance
   done

   
   

2. Enable the Swift service:

   $ kollacli property set enable_swift yes
