OpenContrail Implementations
- 1. OpenContrail Implementations @tcpcloud OpenContrail Meetup 2015 Vancouver
- 2. Agenda • About tcp cloud • What we have done since last meetup? • References • OpenContrail Juno production experience • Fixes, recommendations • Horizon modifications • SaltStack announcements • OpenStack formulas • OpenContrail formulas • OpenContrail modules
- 3. About tcp cloud • ISO Certifications (ISO 9001, ISO 20000-1, ISO 27001) • Certificated experts (cloud, hardware, virtualization, networks, OS, etc…) • Active in global community (OpenStack, OpenContrail, SaltStack, etc…) • Own Hi-Tech Datacenter (TIER III, 20kW per rack, hundreds 10Gbps ports, etc…) • Focused on private open cloud solutions and services (since 2011) • Maximum Openness • Open source of course… • But also technology like • Hyper-V, VMware, PowerKVM, … • Thomas-Krenn, IBM, HP, Dell, … • Juniper, Cisco, … • Ubuntu, CentOS, Windows, …
- 4. What we have done on OpenContrail since last meetup • 6 Proof of Concepts, 2 pilots, 4 prod environments • VMware integration testing (ESXi driver) • Experience with 1.2, 2.0 and 2.1 • AVG Technologies, 100 Percentit IT, Czech IT, telco customers world wide
- 5. OpenStack Juno/OpenContrail Integration • We tested Contrail 1.2 with Icehouse • KVM • ESXi (see blog post) • We have used Juno with Contrail 2.0 since January 2015 • Reasons for Juno: • Heat improvements • Cinder backend drivers • Live migrations for volume backed instances • Horizon improvements • It is newer :)
- 6. Integration issues with 2.0/2.1 and Juno Nova VIF driver compatibility • monkey patching nova VIF drivers • Neutron API Class instead of nova vif... Cannot attach multiple security groups • Except 4 parameters instead of 3 (nova - neutron) • nova/network/security_group/neutron_driver.py Rebuild instances fails • https://review.opencontrail.org/#/c/7477/ Delete failed, when OS::Nova::FloatingIPAssociation cannot find server • https://bugs.launchpad.net/heat/+bug/1396982
- 7. Integration issues with 2.0/2.1 and Juno Heat template is invalid • Increase python-neutronclient 2.3.6 (default 2.3.4.1) on heat- engine New Django URLs, neutron API client fixes • Reflecting Django 1.5 and python-neutronclient changes Dealing with Floating IP associations • Horizon does not allow provision floating IPs to networks without router Eventually Contrail pushed Juno version of horizon cca 14 days ago
- 8. SaltStack based OpenStack deployment • SaltStack has about 5% of OS deployment share • We use hierarchical database as system data model • Proper service (de)composition • Integrated monitoring, logging, firewalls • similar to Example42 approach in Puppet • We are in process of cleaning and opensourcing our formulas • About 30 service formulas in a first wave • Will eventually become part of Big Tent Please Contribute!
- 9. Creating new Salt OpenContrail module and state • Utilises contrail-vnc python client • Declarative peering configuration • Declarative vrouter provisioning
- 10. System model implementation • reclass - external node classification tool • Hiearchical database similar, but not same as Hiera • Basic concepts of hiera • Nested, multiple class inheritance • Variable interpolation
