Install and configure the controller node for Ubuntu¶

Prerequisites¶

The proxy service relies on an authentication and authorization mechanism such as the Identity service. However, unlike other services, it also offers an internal mechanism that allows it to operate without any other OpenStack services. Before you configure the Object Storage service, you must create service credentials and an API endpoint.

1. Source the admin credentials to gain access to admin-only CLI commands:

   $ . admin-openrc
   

2. To create the Identity service credentials, complete these steps:

   • Create the swift user:

     $ openstack user create --domain default --password-prompt swift
     User Password:
     Repeat User Password:
     +-----------+----------------------------------+
     | Field     | Value                            |
     +-----------+----------------------------------+
     | domain_id | e0353a670a9e496da891347c589539e9 |
     | enabled   | True                             |
     | id        | d535e5cbd2b74ac7bfb97db9cced3ed6 |
     | name      | swift                            |
     +-----------+----------------------------------+
     

   • Add the admin role to the swift user:

     $ openstack role add --project service --user swift admin
     

     Note

     This command provides no output.

   • Create the swift service entity:

     $ openstack service create --name swift \
       --description "OpenStack Object Storage" object-store
     +-------------+----------------------------------+
     | Field       | Value                            |
     +-------------+----------------------------------+
     | description | OpenStack Object Storage         |
     | enabled     | True                             |
     | id          | 75ef509da2c340499d454ae96a2c5c34 |
     | name        | swift                            |
     | type        | object-store                     |
     +-------------+----------------------------------+
     

3. Create the Object Storage service API endpoints:

   $ openstack endpoint create --region RegionOne \
     object-store public http://controller:8080/v1/AUTH_%\(tenant_id\)s
   +--------------+----------------------------------------------+
   | Field        | Value                                        |
   +--------------+----------------------------------------------+
   | enabled      | True                                         |
   | id           | 12bfd36f26694c97813f665707114e0d             |
   | interface    | public                                       |
   | region       | RegionOne                                    |
   | region_id    | RegionOne                                    |
   | service_id   | 75ef509da2c340499d454ae96a2c5c34             |
   | service_name | swift                                        |
   | service_type | object-store                                 |
   | url          | http://controller:8080/v1/AUTH_%(tenant_id)s |
   +--------------+----------------------------------------------+
   
   $ openstack endpoint create --region RegionOne \
     object-store internal http://controller:8080/v1/AUTH_%\(tenant_id\)s
   +--------------+----------------------------------------------+
   | Field        | Value                                        |
   +--------------+----------------------------------------------+
   | enabled      | True                                         |

Install and configure components¶

1. Install the packages:

   # apt-get install swift swift-proxy python-swiftclient \
     python-keystoneclient python-keystonemiddleware \
     memcached
   

   Note

   Complete OpenStack environments already include some of these packages.

   2. Create the /etc/swift directory.

   3. Obtain the proxy service configuration file from the Object Storage source repository:

      # curl -o /etc/swift/proxy-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/proxy-server.conf-sample?h=stable/newton
      

   4. Edit the /etc/swift/proxy-server.conf file and complete the following actions:

      • In the [DEFAULT] section, configure the bind port, user, and configuration directory:

        [DEFAULT]
        ...
        bind_port = 8080
        user = swift
        swift_dir = /etc/swift
        

      • In the [pipeline:main] section, remove the tempurl and tempauth modules and add the authtoken and keystoneauth modules:

        [pipeline:main]
        pipeline = catch_errors gatekeeper healthcheck proxy-logging cache container_sync bulk ratelimit authtoken keystoneauth container-quotas account-quotas slo dlo versioned_writes proxy-logging proxy-server
        

        Note

        Do not change the order of the modules.

        Note

        For more information on other modules that enable additional features, see the Deployment Guide.

      • In the [app:proxy-server] section, enable automatic account creation:

        [app:proxy-server]
        use = egg:swift#proxy
        ...
        account_autocreate = True
        

      • In the [filter:keystoneauth] section, configure the operator roles:

        [filter:keystoneauth]
        use = egg:swift#keystoneauth
        ...
        operator_roles = admin,user
        

      • In the [filter:authtoken] section, configure Identity service access:

        [filter:authtoken]
        paste.filter_factory = keystonemiddleware.auth_token:filter_factory
        ...
        auth_uri = http://controller:5000
        auth_url = http://controller:35357
        memcached_servers = controller:11211
        auth_type = password
        project_domain_name = default
        user_domain_name = default
        project_name = service
        username = swift
        password = SWIFT_PASS
        delay_auth_decision = True
        

        Replace SWIFT_PASS with the password you chose for the swift user in the Identity service.

        Note

        Comment out or remove any other options in the [filter:authtoken] section.

      • In the [filter:cache] section, configure the memcached location:

        [filter:cache]
        use = egg:swift#memcache
        ...
        memcache_servers = controller:11211
