2015-12-18Add Management Network For System Administration.Dan Sneddon7-3/+122
This change adds a system management network to all overcloud nodes. The purpose of this network is for system administration, for access to infrastructure services like DNS or NTP, or for monitoring. This allows the management network to be placed on a bond for redundancy, or for the system management network to be an out-of-band network with no routing in or out. The management network might also be configured as a default route instead of the provisioning 'ctlplane' network. This change does not enable the management network by default. An environment file named network-management.yaml may be included to enable the network and ports for each role. The included NIC config templates have been updated with a block that may be uncommented when the management network is enabled. This change also contains some minor cleanup to the NIC templates, particularly the multiple nic templates. Change-Id: I0813a13f60a4f797be04b34258a2cffa9ea7e84f

2015-11-11Change default bond-modeJoe Talerico1-2/+1
The default balance-tcp is causing issues with deployments. Defaulting to active-backup. After ~ 100 guests (total) connectivity to each guest would become spotty (simple pings would fail, then become successful.) In /var/log/messages we saw : "overcloud-controller-1 kernel: openvswitch: ovs-system: deferred action limit reached, drop recirc action" For more details, refer to this link: http://openvswitch.org/pipermail/discuss/2015-October/019168.html Change-Id: Ia0f2592a289e13472b98d97057cd516c5048fe59
2015-09-30Add DnsServers param to network config templatesDan Prince5-0/+25
This patch adds a new optional DnsServers parameter which can be used to provide a custom list of DNS resolvers which will be configured in resolv.conf. Change-Id: I2bb7259ebc09d786dc56da18694c862f802091b1 Depends-On: I9edecfdd4e1d0f39883b72be554cd92c5685881d
2015-09-17Configure ctlplane network with a static IPDan Prince5-31/+184
This patch updates all network configuration templates so that we configure the ctlplane network interface with a static IP instead of using DHCP. The IP address used for the static IP is passed into each nested stack network configuration template via the ControlPlaneIp parameter. Three new nested stack parameters called ControlPlaneSubnetCidr, ControlPlaneDefaultRoute, and EC2MetadataIp have been added to help configure the CIDR, default route, and EC2 metadata route on the ctlplane statically. These parameters can be customized via the parameter_defaults section in the heat environment. A single new template called net-config-static-bridge.yaml has been added to help migrate towards using the static configuration templates when not using network isolation. Depends-On: I257e1cba6dee16f73f75512d1284e1e3b9d4c831 Change-Id: Ib267e6dcf2d5ff77f7a82ee20a123965c2d07565
2015-08-17Remove hardcoded bridge name in bonded compute NIC configDan Sneddon1-1/+1
This change removes a hardcoded value for the bond name in the NIC config for the compute node in the bond-with-vlan NIC config templates. When this hardcoded value of "br-bond" is used, then the Neutron bridge mappings must be set to set to datacentre:br-bond in order for VLAN mode networking to recognize the bridge. By using the input value for bridge_name we will ensure that the controller and compute nodes have the same bridge name (defaults to "br-ex"), and that the defaults will work with VLAN mode.

2015-08-06Support network isolation without external netsDan Prince2-0/+126
This patch adds extra heat environments that can be used to enable network isolation without using the external network. Instead of a separate external network the ctlplane will be used for all of the external/public traffic. Change-Id: Ia542cee02121771d7d57ac701b62d7608e8d1855
2015-07-24Add a default setting for BondInterfaceOvsOptionsDan Sneddon1-1/+2
This change adds a default setting for the OVS bond options to the bond-with-vlans controller.yaml. This default will attempt to bring up LACP bonding, but should that fail it will bring up the bond in active/backup mode. This is a safe configuration if the switch is not configured for bonding.

2015-06-29Add a default route to the external isolated networkDan Sneddon1-4/+12
This change adds a parameter for ExternalInterfaceDefaultRoute and uses that parameter to set the default route on the controller nodes. This allows Horizon and the public APIs to be reachable from routed networks outside the overcloud.

2015-06-27Remove bridge from nic1 in network bond templatesDan Sneddon5-51/+1
The bridge that is built on the bonds in the bond-with-vlans example has an extraneous bridge on the storage and compute templates, and an incorrect bridge on the controller template. There is no reason to do anything on nic1, which is assumed to be the provisioning interface, because it will be configured by DHCP. Also, on the controller template we actually want br-ex to contain the VLAN with the external network, rather than be configured on the provisioning interface.

2015-06-16Configurable vlan_id's for isolated networksDan Prince5-16/+81
This patch adds parameters to configure the various vlan IDs to all of the bond-with-vlans and single-nic-vlans network config templates. Change-Id: Ia6196735927777b73879e8086568f8a435597c6c
2015-06-09Add BondInterfaceOvsOptions parameterDan Prince5-5/+30
This patch adds a new BondInterfaceOvsOptions to the bond-with-vlans network config templates. This can be used to configure things like LACP or the bonding mode via a nested stack heat parameter. The patch also removes the hard coded ovs_options relating to both bond-with-vlans and single-nic-with-vlans configurations which do not actually require this setting to be hard coded because by default OVS trunks vlan ports automatically.

2015-06-09network/config storage role fixesDan Prince3-3/+3
None of the storage roles have Heat parameters for the bridge name. Instead of wiring in Heat parameters for bridge name this patch hard codes the bridge name for the storage roles to 'br-storage'. This functionally fixes the network config scripts for each of the storage roles. For the single-nic-vlans storage roles we also remove the 'bond1' reference which was also incorrectly specified.

2015-05-26os-net-config templates to configure vlans on bondDan Prince6-0/+462
This patch adds 5 new role templates to help configure an OVS bond with vlans on top for each of the overcloud roles. These are meant to represent a more production network which might use isolated nets, and should help facilitate create a CI job which configures a bond w/ vlans on it. The patch also includes an environment file to enable configuration of bonded vlans by simply sourcing this file. Change-Id: Ibe4c9d933445014ce3bec5fb3d7e3139fc40cb32
