Tricircle
|
||||
===============================
|
||||
|
||||
Tricircle is a project for [Openstack cascading solution](https://wiki.openstack.org/wiki/OpenStack_cascading_solution), including the source code of Nova Proxy, Cinder Proxy, Neutron L2/L3 Proxy, Glance sync manager and Ceilometer Proxy(not implemented yet).
|
||||
|
||||
The project name "Tricircle" comes from a fractal. See the blog ["OpenStack cascading and fractal"](https://www.linkedin.com/today/post/article/20140729022031-23841540-openstack-cascading-and-fractal) for more information.
|
||||
|
||||
Important to know
|
||||
-----------
|
||||
* the initial source code is for PoC only. Refactory will be done constantly to reach OpenStack acceptance standard.
|
||||
* the PoC source code is based on IceHouse version, while Neutron is a master branch snapshot on July 1, 2014 which include DVR feature, not IceHouse version. The Neutron code is download from github when it was still in the developement and review status. The source code of DVR part is not stable, and not all DVR features are included, for example, N-S functions not ready.
|
||||
* The Neutron cascading using the feature of provider network. But horizon doen't support provider network very well. So you have to use Neutron CLI to create a network. Or set default provide network type to VxLAN, or remove "local", "flat", "VLAN", "GRE" network typedriver from ML2 plugin configuration.
|
||||
* For Neutron L2/L3 features, only VxLAN/L3 across casacaded OpenStack supported in the current source code. VLAN2VLAN, VLAN2VxLAN and VxLAN2VxLAN across cascaded OpenStack also implemented with IceHouse version but the patch is not ready yet, source code is in the VLAN2VLAN folder.
|
||||
* The tunneling network for cross OpenStack piggy data path is using VxLAN, it leads to modification on L2 agent and L3 agent, we will refactory it to using GRE for the tunneling network to reduce patch for Juno version.
|
||||
* If you want to experience VLAN2VLAN, VLAN2VxLAN and VxLAN2VxLAN across cascaded OpenStack, please ask help from PoC team member, see the wiki page [Openstack cascading solution](https://wiki.openstack.org/wiki/OpenStack_cascading_solution) for contact information.
|
||||
* Glance cascading using Glance V2 API. Only CLI/pythonclient support V2 API, the Horizon doesn't support that version. So image management should be done through CLI, and using V2 only. Otherwise, the glance cascading cannot work properly.
|
||||
* Glance cascading is not used by default, eg, useing global Glance by default. If Glance cascading is required, configuration is required.
|
||||
* Refactory the Tricircle source code based on Juno version will be started soon once the Juno version is available.
|
||||
|
||||
|
||||
Key modules
|
||||
-----------
|
||||
|
||||
* Nova proxy
|
||||
|
||||
Similar role like Nova-Compute. Transfer the VM operation to cascaded Nova. Also responsible for attach volume and network to the VM in the cascaded OpenStack.
|
||||
|
||||
* Cinder proxy
|
||||
|
||||
Similar role like Cinder-Volume. Transfer the volume operation to cascaded Cinder.
|
||||
|
||||
* Neuton proxy
|
||||
|
||||
Including L2 proxy and L3 proxy, Similar role like OVS-Agent/L3-Agent. Finish L2/L3-networking in the cascaded OpenStack, including cross OpenStack networking.
|
||||
|
||||
* Glance sync
|
||||
|
||||
Synchronize image among the cascading and policy determined Cascaded OpenStacks
|
||||
|
||||
Patches required
|
||||
------------------
|
||||
|
||||
* IceHouse-Patches
|
||||
|
||||
Pacthes for OpenStack IceHouse version, including patches for cascading level and cacscaded level.
|
||||
|
||||
Feature Supported
|
||||

|
||||
|
||||
* Glance cascading
|
||||
Only support V2 api. Create Image/Delete Image/List Image/Update Image/Upload Image/Patch Location/VM Snapshot/Image Synchronization
|
||||
|
||||
Known Issues
|
||||
------------------
|
||||
* Use "admin" role to experience these feature first, multi-tenancy has not been tested well.
|
||||
* Launch VM only support "boot from image", "boot from volume", "boot from snapshot"
|
||||
* Flavor only support new created flavor synchronized to the cascaded OpenStack, does not support flavor update synchronization to cascaded OpenStack yet.
|
||||
* Must make a patch for "Create a volume from image", the patch link: https://bugs.launchpad.net/cinder/+bug/1308058
|
||||
|
||||
Installation without Glance cascading
|
||||
------------
|
||||
|
||||
* **Prerequisites**
|
||||
- the minimal installation requires three OpenStack IceHouse installated to experience across cascaded OpenStacks L2/L3 function. The minimal setup needs four nodes, see the following picture:
|
||||
|
||||
|
||||
|
||||
- the cascading OpenStack needs two node, Node1 and Node 2. Add Node1 to AZ1, Node2 to AZ2 in the cascading OpenStack for both Nova and Cinder.
|
||||
|
||||
- It's recommended to name the cascading Openstack region to "Cascading_OpenStack" or "Region1"
|
||||
|
||||
- Node1 is all-in-one OpenStack installation with KeyStone and Glance, Node1 also function as Nova-Compute/Cinder-Volume/Neutron OVS-Agent/L3-Agent node, and will be replaced to be the proxy node for AZ1.
|
||||
|
||||
- Node2 is general Nova-Compute node with Cinder-Volume, Neutron OVS-Agent/L3-Agent function installed. And will be replaced to be the proxy node for AZ2
|
||||
|
||||
- the all-in-one cascaded OpenStack installed in Node3 function as the AZ1. Node3 will also function as the Nova-Compute/Cinder-Volume/Neutron OVS-Agent/L3-Agent in order to be able to create VMs/Volume/Networking in this AZ1. Glance is only required to be installed if Glance cascading needed. Add Node3 to AZ1 in the cascaded OpenStack both for Nova and Cinder. It's recommended to name the cascaded Openstack region for Node3 to "AZ1"
|
||||
|
||||
- the all-in-one cascaded OpenStack installed in Node4 function as the AZ2. Node3 will also function as the Nova-Compute/Cinder-Volume/Neutron OVS-Agent/L3-Agent in order to be able to create VMs/Volume/Networking in this AZ2. Glance is only required to be installed if Glance cascading needed.Add Node4 to AZ2 in the cascaded OpenStack both for Nova and Cinder.It's recommended to name the cascaded Openstack region for Node4 to "AZ2"
|
||||
|
||||
Make sure the time of these four nodes are synchronized. Because the Nova Proxy/Cinder Proxy/Neutron L2/L3 Proxy will query the cascaded OpenStack using timestamp, incorrect time will lead to VM/Volume/Port status synchronization not work properly.
|
||||
|
||||
Register all services endpoint in the global shared KeyStone.
|
||||
|
||||
Make sure the 3 OpenStack can work independently before cascading introduced, eg. you can boot VM with network, create volume and attach volume in each OpenStack. After verify that 3 OpenStack can work independently, clean all created resources VM/Volume/Network.
|
||||
|
||||
After all OpenStack installation is ready, it's time to install IceHouse pathces both for cascading OpenStack and cascaded OpenStack, and then replace the Nova-Compute/Cinder-Volume/Neutron OVS-Agent/L3-Agent to Nova Proxy / Cinder Proxy / Neutron l2/l3 Proxy.

|
||||
|
||||
5. Experience Glance cascading
|
||||
- Restart all related service
|
||||

Openstack Cinder Proxy
|
||||
===============================
|
||||
|
||||
Cinder-Proxy acts as the same role of Cinder-Volume in cascading OpenStack.
|
||||
Cinder-Proxy treats cascaded Cinder as its cinder volume, convert the internal request message from the message bus to restful API calling to cascaded Cinder.
|
||||
|
||||
|
||||
Key modules
|
||||
-----------
|
||||
|
||||
* The new cinder proxy module cinder_proxy,which treats cascaded Cinder as its cinder volume, convert the internal request message from the message bus to restful API calling to cascaded Cinder:
|
||||
|
||||
cinder/volume/cinder_proxy.py
|
||||
|
||||
Requirements
|
||||
------------
|
||||
* openstack-cinder-volume-2014.1-14.1 has been installed
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
We provide two ways to install the cinder proxy code. In this section, we will guide you through installing the cinder proxy with the minimum configuration.
|
||||
|
||||
* **Note:**
|
||||
|
||||
- Make sure you have an existing installation of **Openstack Icehouse**.
|
||||
- We recommend that you Do backup at least the following files before installation, because they are to be overwritten or modified:
|
||||
$CINDER_CONFIG_PARENT_DIR/cinder.conf
|
||||
(replace the $... with actual directory names.)
|
||||
|
||||
* **Manual Installation**
|
||||
|
||||
- Make sure you have performed backups properly.
|
||||
|
||||
- Navigate to the local repository and copy the contents in 'cinder' sub-directory to the corresponding places in existing cinder, e.g.
|
||||
```cp -r $LOCAL_REPOSITORY_DIR/cinder $CINDER_PARENT_DIR```
|
||||
(replace the $... with actual directory name.)
|
||||
|
||||
- Update the cinder configuration file (e.g. /etc/cinder/cinder.conf) with the minimum option below. If the option already exists, modify its value, otherwise add it to the config file. Check the "Configurations" section below for a full configuration guide.
|
||||
```

|
||||
```
|
||||
|
||||
- Restart the cinder proxy.
|
||||
```service openstack-cinder-volume restart```
|
||||
|
||||
- Done. The cinder proxy should be working with a demo configuration.
|
||||
|
||||
* **Automatic Installation**
|
||||
|
||||
- Make sure you have performed backups properly.
|
||||
|
||||
- Navigate to the installation directory and run installation script.
|
||||
```
|
||||
cd $LOCAL_REPOSITORY_DIR/installation
|
||||
sudo bash ./install.sh
|
||||
```
|
||||
(replace the $... with actual directory name.)
|
||||
|
||||
- Done. The installation code should setup the cinder proxy with the minimum configuration below. Check the "Configurations" section for a full configuration guide.

|
||||
* **Troubleshooting**
|
||||
|
||||
In case the automatic installation process is not complete, please check the followings:
|
||||
|
||||
- Make sure your OpenStack version is Icehouse.
|
||||
|
||||
- Check the variables in the beginning of the install.sh scripts. Your installation directories may be different from the default values we provide.
|
||||
|
||||
- The installation code will automatically add the related codes to $CINDER_PARENT_DIR/cinder and modify the related configuration.
|
||||
|
||||
- In case the automatic installation does not work, try to install manually.
|
||||
|
||||
Configurations
|
||||
--------------
|
||||
|
||||
* This is a (default) configuration sample for the cinder proxy. Please add/modify these options in /etc/cinder/cinder.conf.
|
||||
* Note:
|
||||
- Please carefully make sure that options in the configuration file are not duplicated. If an option name already exists, modify its value instead of adding a new one of the same name.
|
||||
- Please refer to the 'Configuration Details' section below for proper configuration and usage of costs and constraints.

Glance Sync Manager
|
||||
===============================
|
||||
|
||||
This is a submodule of Tricircle Project, in which a sync function is added to support the glance images' sync between cascading and cascadeds.
|
||||
When launching a instance, the nova will search the image which is in the same region with the instance to downland, this can speeded up the whole launching time of the instance.
|
||||
|
||||
Key modules
|
||||
-----------
|
||||
|
||||
* Primarily, there is only new module in glance cascading: Sync, which is in the glance/sync package.
|
||||
|
||||
glance/sync/__init__.py : Adds a ImageRepoProxy class, like store, policy .etc , to augment a sync mechanism layer on top of the api request handling chain.
|
||||
glance/sync/base.py : Contains SyncManager object, execute the sync operations.
|
||||
glance/sync/utils.py : Some help functions.
|
||||
glance/sync/api/ : Support a Web Server of sync.
|
||||
glance/sync/client/: Support a client to visit the Web Server , ImageRepoProxy use this client to call the sync requests.
|
||||
glance/sync/task/: Each Sync operation is transformed into a task, we using queue to store the task an eventlet to handle the task simultaneously.
|
||||
glance/sync/store/: We implements the independent-glance-store, separating the handles of image_data from image_metadata.
|
||||
glance/cmd/sync.py: For the Sync Server starting launch (refer this in /usr/bin/glance-sync).
|
||||
|
||||
|
||||
|
||||
* **Note:**
|
||||
At present, the glance cascading only support v2 version of glance-api;
|
||||
|
||||
Requirements
|
||||
------------
|
||||
|
||||
* pexpect>=2.3
|
||||
|
||||
Installation
|
||||
------------
|
||||
* **Note:**
|
||||
- The Installation and configuration guidelines written below is just for the cascading layer of glance. For the cascaded layer, the glance is installed as normal.
|
||||
|
||||
* **Prerequisites**
|
||||
- Please install the python package: pexpect>=2.3 ( because we use pxssh for loginng and there is a bug in pxssh, see https://mail.python.org/pipermail/python-list/2008-February/510054.html, you should fix this before launch the service. )
|
||||
|
||||
* **Manual Installation**
|
||||
|
||||
- Make sure you have performed backups properly.
|
||||
* **Manual Installation**
|
||||
|
||||
1. Under cascading Openstack, copy these files from glance-patch directory and glancesync directory to suitable place:
|
||||
|
||||
| DIR | FROM | TO |
|
||||
| ------------- |:-----------------|:-------------------------------------------|
|
||||
| glancesync | glance/ | ${python_install_dir}/glance |
|
||||
| glancesync | etc/glance/ | /etc/glance/ |
|
||||
| glancesync | glance-sync | /usr/bin/ |
|
||||
|${glance-patch}| glance/ | ${python_install_dir}/glance |
|
||||
|${glance-patch}|glance.egg-info/entry_points.txt | ${glance_install_egg.info}/ |
|
||||
|
||||
${glance-patch} = `icehouse-patches/glance/glance_location_patch` ${python_install_dir} is where the openstack installed, e.g. `/usr/lib64/python2.6/site-packages` .
|
||||
2. Add/modify the config options
|
||||
|
||||
| CONFIG_FILE | OPTION | ADD or MODIFY |
|
||||
| ----------------|:---------------------------------------------------|:--------------:|
|
||||
|glance-api.conf | show_multiple_locations=True | M |
|
||||
|glance-api.conf | sync_server_host=${sync_mgr_host} | A |
|
||||
|glance-api.conf | sync_server_port=9595 | A |
|
||||
|glance-api.conf | sync_enabled=True | A |
|
||||
|glance-sync.conf | cascading_endpoint_url=${glance_api_endpoint_url} | M |
|
||||
|glance-sync.conf | sync_strategy=ALL | M |
|
||||
|glance-sync.conf | auth_host=${keystone_host} | M |
|
||||
3. Re-launch services on cacading openstack, like:
|
||||
|
||||
`service openstack-glance-api restart `
|
||||
`service openstack-glance-registry restart `
|
||||
`python /usr/bin/glance-sync --config-file=/etc/glance/glance-sync.conf & `
|
||||
|
||||
* **Automatic Installation**
|
||||
|
||||
1. Enter the glance-patch installation dir: `cd ./tricircle/icehouse-patches/glance/glance_location_patch/installation` .
|
||||
2. Optional, modify the shell script variable: `_PYTHON_INSTALL_DIR` .
|
||||
3. Run the install script: `sh install.sh`
|
||||
4. Enter the glancesync installation dir: `cd ./tricircle/glancesync/installation` .
|
||||
5. Modify the cascading&cascaded glances' store scheme configuration, which is in the file: `./tricircle/glancesync/etc/glance/glance_store.yaml` .
|
||||
6. Optional, modify the config options in shell script: `sync_enabled=True`, `sync_server_port=9595`, `sync_server_host=127.0.0.1` with the proper values.
|
||||
7. Run the install script: `sh install.sh`
|
||||
|
||||
Configurations
|
||||
--------------
|
||||
|
||||
Besides glance-api.conf file, we add some new config files. They are described separately.
|
||||
|
||||
- In glance-api.conf, three options added:
|
||||
|
||||
[DEFAULT]
|
||||
|
||||
# Indicate whether use the image sync, default value is False.
|
||||
#If configuring on cascading layer, this value should be True.
|
||||
sync_enabled = True
|
||||
|
||||
#The sync server 's port number, default is 9595.
|
||||
sync_server_port = 9595
|
||||
|
||||
#The sync server's host name (or ip address)
|
||||
sync_server_host = 127.0.0.1
|
||||
|
||||
*Besides, the option show_multiple_locations value should be ture.
|
||||
- In glance-sync.conf which newly increased, the options is similar with glance-registry.conf except:
|
||||
|
||||
[DEFAULT]
|
||||
|
||||
#How to sync the image, the value can be ["None", "ALL", "USER"]
|
||||
#When "ALL" choosen, means to sync to all the cascaded glances;
|
||||
#When "USER" choosen, means according to user's role, project, etc.
|
||||
sync_strategy = ALL
|
||||
|
||||
#What the cascading glance endpoint url is .(Note that this value should be consistent with what in keystone).
|
||||
cascading_endpoint_url = http://127.0.0.1:9292/
|
||||
|
||||
#when snapshot sync, set the timeout time(second) of snapshot 's status
|
||||
#changing into 'active'.
|
||||
snapshot_timeout = 300
|
||||
|
||||
#when snapshot sync, set the polling interval time(second) to check the
|
||||
#snapshot's status.
|
||||
snapshot_sleep_interval = 10
|
||||
|
||||
#When sync task fails, set the retry times.
|
||||
task_retry_times = 0
|
||||
|
||||
#When copy image data using 'scp' between filesystmes, set the timeout
|
||||
#time of the copy.
|
||||
scp_copy_timeout = 3600
|
||||
|
||||
#When snapshot, one can set the specific regions in which the snapshot
|
||||
#will sync to. (e.g. physicalOpenstack001, physicalOpenstack002)
|
||||
snapshot_region_names =
|
||||
|
||||
- Last but also important, we add a yaml file for config the store backend's copy : glance_store.yaml in cascading glance.
|
||||
these config correspond to various store scheme (at present, only filesystem is supported), the values
|
||||
are based on your environment, so you have to config it before installation or restart the glance-sync
|
||||
when modify it.
