So how does that # make sense? The answer is that rtslib-fb is only used by Cinder, and we don't # use either Cinder or DevStack in our ST. # # We want to keep running DevStack CI with Yoga, and Semaphore's available # machine types mean that we now have to do that on Jammy. We also want to keep # installing Cinder in our DevStack setup, because otherwise we can't run the # "minimum basic scenario" test. So, hack the Yoga install here by updating # rtslib-fb to v2.1.76. # # To be clear, this is unrelated to Calico. It's a workaround to make OpenStack # Yoga code compatible with Jammy. I'm placing the workaround here simply # because it's the most convenient place to put it, prior to Cinder being # installed. if [ "${DEVSTACK_BRANCH}" = unmaintained/yoga ]; then sed -i 's,rtslib-fb===2.1.74,rtslib-fb===2.1.76,' ${REQUIREMENTS_DIR}/upper-constraints.txt grep rtslib-fb ${REQUIREMENTS_DIR}/upper-constraints.txt pip_install rtslib-fb==2.1.76 fi ;; install) # Called after the layer 1 and 2 projects source # and their dependencies have been installed. echo Calico plugin: install # Upgrade dnsmasq. install_package dnsmasq-base dnsmasq-utils # Install ipset. install_package ipset if [ "${CALICO_BGP_MODE}" = bird ]; then # Install BIRD. install_package bird fi # Install the Calico agent. sudo mkdir -p /etc/calico sudo sh -c "cat > /etc/calico/felix.cfg" << EOF [global] DatastoreType = etcdv3 EtcdEndpoints = http://${SERVICE_HOST}:${ETCD_PORT} EndpointStatusPathPrefix = none EOF if [ "${ENABLE_DEBUG_LOG_LEVEL}" = True ]; then sudo sh -c "cat >> /etc/calico/felix.cfg" << EOF LogSeverityFile = info EOF fi install_package calico-felix # Install Calico common code, that includes BIRD templates. install_package calico-common # Install networking-calico. pip_install "${GITDIR['calico']}/networking-calico" ;; post-config) # Called after the layer 1 and 2 services have # been configured.
