devtest_overcloud_images

Build images with environment variables. This script works best when using tripleo-image-elements for Overcloud configuration.

1. Undercloud UI needs SNMPd for monitoring of every Overcloud node

   if [ "$USE_UNDERCLOUD_UI" -ne 0 ] ; then
       OVERCLOUD_CONTROL_DIB_EXTRA_ARGS="$OVERCLOUD_CONTROL_DIB_EXTRA_ARGS snmpd"
       OVERCLOUD_COMPUTE_DIB_EXTRA_ARGS="$OVERCLOUD_COMPUTE_DIB_EXTRA_ARGS snmpd"
       OVERCLOUD_BLOCKSTORAGE_DIB_EXTRA_ARGS="$OVERCLOUD_BLOCKSTORAGE_DIB_EXTRA_ARGS snmpd"
   fi
   

2. Create your overcloud control plane image.

   $OVERCLOUD_*_DIB_EXTRA_ARGS (CONTROL, COMPUTE, BLOCKSTORAGE) are meant to be used to pass additional build-time specific arguments to disk-image-create.

   $SSL_ELEMENT is used when building a cloud with SSL endpoints - it should be set to openstack-ssl in that situation.

   if [ ! -e $TRIPLEO_ROOT/overcloud-control.qcow2 -o "$USE_CACHE" == "0" ] ; then
       $TRIPLEO_ROOT/diskimage-builder/bin/disk-image-create $NODE_DIST \
           -a $NODE_ARCH -o $TRIPLEO_ROOT/overcloud-control \
           $OVERCLOUD_CONTROL_DIB_ELEMENTS \
           $DIB_COMMON_ELEMENTS $OVERCLOUD_CONTROL_DIB_EXTRA_ARGS ${SSL_ELEMENT:-} 2>&1 | \
           tee $TRIPLEO_ROOT/dib-overcloud-control.log
   fi
   

3. Create your block storage image if some block storage nodes are to be used. This is the image the undercloud deploys for the additional cinder-volume nodes.

   if [ ${OVERCLOUD_BLOCKSTORAGESCALE:-0} -gt 0 ]; then
       if [ ! -e $TRIPLEO_ROOT/overcloud-cinder-volume.qcow2 -o "$USE_CACHE" == "0" ]; then
           $TRIPLEO_ROOT/diskimage-builder/bin/disk-image-create $NODE_DIST \
               -a $NODE_ARCH -o $TRIPLEO_ROOT/overcloud-cinder-volume \
               $OVERCLOUD_BLOCKSTORAGE_DIB_ELEMENTS $DIB_COMMON_ELEMENTS \
               $OVERCLOUD_BLOCKSTORAGE_DIB_EXTRA_ARGS 2>&1 | \
               tee $TRIPLEO_ROOT/dib-overcloud-cinder-volume.log
       fi
   fi
   

   If enabling distributed virtual routing for Neutron on the overcloud the compute node must have the neutron-router element installed.

   OVERCLOUD_DISTRIBUTED_ROUTERS=${OVERCLOUD_DISTRIBUTED_ROUTERS:-'False'}
   OVERCLOUD_L3=${OVERCLOUD_L3:-'relocate'}
   if [ $OVERCLOUD_DISTRIBUTED_ROUTERS == "True" -o $OVERCLOUD_L3 == "dvr"  ]; then
       OVERCLOUD_COMPUTE_DIB_ELEMENTS="$OVERCLOUD_COMPUTE_DIB_ELEMENTS neutron-router"
   fi
   

4. Create your overcloud compute image. This is the image the undercloud deploys to host the overcloud Nova compute hypervisor components.

   if [ ! -e $TRIPLEO_ROOT/overcloud-compute.qcow2 -o "$USE_CACHE" == "0" ]; then
       $TRIPLEO_ROOT/diskimage-builder/bin/disk-image-create $NODE_DIST \
           -a $NODE_ARCH -o $TRIPLEO_ROOT/overcloud-compute \
           $OVERCLOUD_COMPUTE_DIB_ELEMENTS $DIB_COMMON_ELEMENTS \
           $OVERCLOUD_COMPUTE_DIB_EXTRA_ARGS 2>&1 | \
           tee $TRIPLEO_ROOT/dib-overcloud-compute.log
   fi
