This task aims to change the IP acquisition method for Nova compute pods from the Nova plugin to a new environment variable that maps to the status.hostIP field. The environment variable-based approach will provide the cluster host IP address to the Nova compute container. With the goal of assisting in the task of deploying Nova compute with fewer daemonsets, grouping hosts with identical configurations, and consequently making the solution more scalable, this implementation removes the responsibility from the plugin of setting the IP information, since doing so would prevent the grouping of the override configurations due to having different values for each compute host. Using the environment variable-based approach, the IP change will occur inside the container just before executing the nova-compute command. Since this task aims to set the IP inside the container and the Nova configuration file located at /etc/nova is read-only, a new Nova configuration file has been created, which is located inside the compute container at /tmp/pod-shared, a similar approach of using this path is already followed by other Nova configuration files (nova-console.conf, nova-hypervisor.conf and nova-libvirt.conf). The difference between the two nova.conf files is only the IPs in fields my_ip, server_listen, server_proxyclient_address and live_migration_inbound_addr, which will contain the cluster host IP configured in the new environment variable in the new one. TEST PLAN: PASS: build-pkg -c -l openstack PASS: build openstack tarball PASS: upload and apply openstack tarball on standard system PASS: nova-compute pod is running PASS: CLUSTER_HOST_IP environment variable created with .status.hostIP value PASS: /tmp/pod-shared/nova.conf has the same configuration of /etc/nova/nova.conf, with the only difference being that the fields: DEFAULT.my_ip vnc.server_listen vnc.server_proxyclient_address and libvirt.live_migration_inbound_addr are updated with the IP from the new environment variable PASS: launch a guest instance (tis-centos-guest VM) Story: 2011304 Task: 51517 Change-Id: I19792f4c15bc9adddc7e45c2d600ddeb1b3ec420 Signed-off-by: marantes <murillo.arantes@windriver.com> |
