From daa0b91119d2c16860a19b4ead2d0d128f8bc5ce Mon Sep 17 00:00:00 2001 From: Tomas Sedovic Date: Wed, 6 Sep 2017 10:24:16 +0200 Subject: Allow using a provider network (#701) * Allow using a provider network This adds a new option `openstack_provider_network_name` which will take a name of an existing network and put the servers there. It will also prevent creating floating IP addresses as the provider network's IPs should already be accessible without any additional routing required. Fixes #622 * Requested changes Don't fail on external/private networks and use role defaults for the provider network. * Add missing endif --- roles/openstack-stack/defaults/main.yml | 1 + .../tasks/subnet_update_dns_servers.yaml | 1 + roles/openstack-stack/templates/heat_stack.yaml.j2 | 113 +++++++++++++++------ .../templates/heat_stack_server.yaml.j2 | 12 +++ roles/static_inventory/tasks/openstack.yml | 25 ++++- 5 files changed, 119 insertions(+), 33 deletions(-) (limited to 'roles') diff --git a/roles/openstack-stack/defaults/main.yml b/roles/openstack-stack/defaults/main.yml index fbca0bdf6..c16b5dc00 100644 --- a/roles/openstack-stack/defaults/main.yml +++ b/roles/openstack-stack/defaults/main.yml @@ -15,3 +15,4 @@ dns_volume_size: 1 lb_volume_size: 5 use_bastion: False ui_ssh_tunnel: False +provider_network: None diff --git a/roles/openstack-stack/tasks/subnet_update_dns_servers.yaml b/roles/openstack-stack/tasks/subnet_update_dns_servers.yaml index be4f07b97..af28fc98f 100644 --- a/roles/openstack-stack/tasks/subnet_update_dns_servers.yaml +++ b/roles/openstack-stack/tasks/subnet_update_dns_servers.yaml @@ -6,3 +6,4 @@ state: present use_default_subnetpool: yes dns_nameservers: "{{ [private_dns_server|default(public_dns_nameservers[0])]|union(public_dns_nameservers)|unique }}" + when: not provider_network diff --git a/roles/openstack-stack/templates/heat_stack.yaml.j2 b/roles/openstack-stack/templates/heat_stack.yaml.j2 index ea2742a2c..b6b5e3613 100644 --- a/roles/openstack-stack/templates/heat_stack.yaml.j2 +++ b/roles/openstack-stack/templates/heat_stack.yaml.j2 @@ -73,6 +73,7 @@ outputs: resources: +{% if not provider_network %} net: type: OS::Neutron::Net properties: @@ -129,6 +130,8 @@ resources: router_id: { get_resource: router } subnet_id: { get_resource: subnet } +{% endif %} + # keypair: # type: OS::Nova::KeyPair # properties: @@ -501,22 +504,29 @@ resources: image: {{ openstack_etcd_image }} flavor: {{ etcd_flavor }} key_name: {{ ssh_public_key }} +{% if provider_network %} + net: {{ provider_network }} + net_name: {{ provider_network }} +{% else %} net: { get_resource: net } subnet: { get_resource: subnet } -
