2016-08-11Convert EndpointMap to not require per-service VIP parametersSteven Hardy1-18/+30
Currently we have a hard-coded set of per-service parameters, which will cause problems for custom roles and full composability. As a first step towards making this more configurable, remove the hard-coded per-service parameters from overcloud.yaml, and adjust the EndpointMap generation to instead accept two mappings, the ServiceNetMap and a mapping of networks to IPs (effectively this just moves the map lookup inside the endpoint map instead of inside overcloud.yaml) Change-Id: Ib522e89c36eed2115a6586dd5a6770907d9b33db Partially-Implements: blueprint custom-roles
2016-03-04Add IPv6 Support to Isolated NetworksDan Sneddon1-1/+4
This change adds a new set of network templates with IPv6 subnets that can be used instead of the existing IPv4 networks. Each network can use either the IPv4 or IPv6 template, and the Neutron subnet will be created with the specified IP version. The default addresses used for the IPv6 networks use the fd00::/8 prefix for the internal isolated networks (this range is reserved for private use similar to 10.0.0.0/8), and 2001:db8:fd00:1000::/64 is used as an example default for the External network (2001:db8::/32 are the documentation addresses [RFC3849]), but this would ordinarily be a globally addressable subnet. These parameters may be overridden in an environment file. This change will require updates to the OpenStack Puppet Modules to support IPv6 addresses in some of the hieradata values. Many of the OPM modules already have IPv6 support to support IPv6 deployments in Packstack, but some OPM packages that apply only to Instack/TripleO deployments need to be updated. IPv6 addresses used in URLs need to be surrounded by brackets in order to differentiate IP address from port number. This change adds a new output to the network/ports resources for ip_address_uri, which is an IP address with brackets in the case of IPv6, and a raw IP address without brackets for IPv4 ports. This change also updates some URLs which are constructed in Heat. This has been tested and problems were found with Puppet not accepting IPv6 addresses. This is addressed in the latest Puppet. Additional changes were required to make this work with Ceph. IPv6 tunnel endpoints with Open vSwitch are not yet supported (although support is coming soon), so this review leaves the Tenant network as an isolated IPv4 network for the time being.

2016-02-24Generate the endpoint map staticallyZane Bitter1-0/+274
A stack is an extremely heavyweight abstraction in Heat. Particularly in TripleO, every stack includes a copy of all the template and environment data for all of the stacks in the tree, all of which must be stored anew in the database. The EndpointMap abstraction created no fewer than 30 nested stacks, none of which contained any resources but which existed purely for the purpose of abstracting out some intrinsic functions used to calculate the endpoint URLs for the various services. This likely adds several GB to the memory requirements of the undercloud, and can cause things to slow to a crawl since all 30 nested stacks need to be queried whenever we need data from any one of them. This change eliminates the nested stacks and instead generates the endpoint map statically. This can be done offline in less than 250ms, allows the input data to be expressed in an even more human-readable form, and reduces the runtime overhead of the endpoints map by a factor of 31, all with no loss of functionality, compatibility or flexibility. Since we don't run a setup script to generate the tarball, the endpoint_map.yaml output is checked in to source control. The build script offers a --check option that can be used to make sure that the output file is up-to-date with the input data. Change-Id: I2df8f5569d81c1bde417ff5b12b06b7f1e19c336
