Install and configure controller node for Ubuntu

This section describes how to install and configure the Container service for Ubuntu 16.04 (LTS).

Prerequisites

Before you install and configure Zun, you must create a database, service credentials, and API endpoints.

To create the database, complete these steps:
- Use the database access client to connect to the database server as the root user:
```
# mysql
```
- Create the zun database:
```
MariaDB [(none)] CREATE DATABASE zun;
```
- Grant proper access to the zun database:
```
MariaDB [(none)]> GRANT ALL PRIVILEGES ON zun.* TO 'zun'@'localhost' \
  IDENTIFIED BY 'ZUN_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON zun.* TO 'zun'@'%' \
  IDENTIFIED BY 'ZUN_DBPASS';
```
  Replace ZUN_DBPASS with a suitable password.
- Exit the database access client.
Source the admin credentials to gain access to admin-only CLI commands:
```
$ . admin-openrc
```

To create the service credentials, complete these steps:

Create the zun user:

$ openstack user create --domain default --password-prompt zun
User Password:
Repeat User Password:
+-----------+----------------------------------+
| Field     | Value                            |
+-----------+----------------------------------+
| domain_id | e0353a670a9e496da891347c589539e9 |
| enabled   | True                             |
| id        | ca2e175b851943349be29a328cc5e360 |
| name      | zun                              |
+-----------+----------------------------------+

Add the admin role to the zun user:
```
$ openstack role add --project service --user zun admin
```
Note

This command provides no output.

Create the zun service entities:

$ openstack service create --name zun \
    --description "Container Service" container
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+

| enabled     | True                             |
| id          | 727841c6f5df4773baa4e8a5ae7d72eb |
| name        | zun                              |
| type        | container                        |
+-------------+----------------------------------+

Create the Container service API endpoints:

$ openstack endpoint create --region RegionOne \
    container public http://controller:9517/v1

Install and configure components

Create zun user and necessary directories:

Create user:

# groupadd --system zun
# useradd --home-dir "/var/lib/zun" \
      --create-home \
      --system \
      --shell /bin/false \
      -g zun \
      zun

Create directories:

# mkdir -p /etc/zun
# chown zun:zun /etc/zun

Clone and install zun:

# apt-get install python-pip
# cd /var/lib/zun
# git clone https://git.openstack.org/openstack/zun.git
# chown -R zun:zun zun
# cd zun
# pip install -r requirements.txt
# python setup.py install

Generate a sample configuration file:

# su -s /bin/sh -c "oslo-config-generator \
    --config-file etc/zun/zun-config-generator.conf" zun
# su -s /bin/sh -c "cp etc/zun/zun.conf.sample \
    /etc/zun/zun.conf" zun

Copy api-paste.ini:

# su -s /bin/sh -c "cp etc/zun/api-paste.ini /etc/zun" zun

Edit the /etc/zun/zun.conf:

In the [DEFAULT] section, configure RabbitMQ message queue access:
```
[DEFAULT]
...
transport_url = rabbit://openstack:RABBIT_PASS@controller
```
Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.
In the [api] section, configure the IP address that Zun API server is going to listen:
```
[api]
...
host_ip = 10.0.0.11
port = 9517
```
Replace 10.0.0.11 with the management interface IP address of the controller node if different.
In the [database] section, configure database access:
```
[database]
...
connection = mysql+pymysql://zun:ZUN_DBPASS@controller/zun
```
Replace ZUN_DBPASS with the password you chose for the zun database.

In the [keystone_auth] section, configure Identity service access:

[keystone_auth]
memcached_servers = controller:11211
www_authenticate_uri = http://controller:5000
project_domain_name = default
project_name = service
user_domain_name = default
password = ZUN_PASS
username = zun
auth_url = http://controller:5000
auth_type = password
auth_version = v3
auth_protocol = http
service_token_roles_required = True
endpoint_type = internalURL

In the [keystone_authtoken] section, configure Identity service access:

[keystone_authtoken]
...
memcached_servers = controller:11211
www_authenticate_uri = http://controller:5000
project_domain_name = default
project_name = service
user_domain_name = default
password = ZUN_PASS
username = zun
auth_url = http://controller:5000
auth_type = password
auth_version = v3
auth_protocol = http
service_token_roles_required = True
endpoint_type = internalURL

Replace ZUN_PASS with the password you chose for the zun user in the Identity service.

In the [oslo_concurrency] section, configure the lock_path:
```
[oslo_concurrency]
...
lock_path = /var/lib/zun/tmp
```
In the [oslo_messaging_notifications] section, configure the driver:
```
[oslo_messaging_notifications]
...
driver = messaging
```

In the [websocket_proxy] section, configure the IP address that the websocket proxy is going to listen to:

[websocket_proxy]
...
wsproxy_host = 10.0.0.11
wsproxy_port = 6784
base_url = ws://controller:6784/

.. note::

  This ``base_url`` will be used by end users to access the console of
  their containers so make sure this URL is accessible from your
  intended users and the port ``6784`` is not blocked by firewall.

Replace 10.0.0.11 with the management interface IP address of the controller node if different.

Note

Make sure that /etc/zun/zun.conf still have the correct permissions. You can set the permissions again with:

# chown zun:zun /etc/zun/zun.conf

Populate Zun database:

# su -s /bin/sh -c "zun-db-manage upgrade" zun

Finalize installation

Create an upstart config, it could be named as /etc/systemd/system/zun-api.service:

[Unit]
Description = OpenStack Container Service API

[Service]
ExecStart = /usr/local/bin/zun-api
User = zun

[Install]
WantedBy = multi-user.target

Create an upstart config, it could be named as /etc/systemd/system/zun-wsproxy.service:

[Unit]
Description = OpenStack Container Service Websocket Proxy

[Service]
ExecStart = /usr/local/bin/zun-wsproxy
User = zun

[Install]
WantedBy = multi-user.target

Enable and start zun-api and zun-wsproxy:

# systemctl enable zun-api
# systemctl enable zun-wsproxy

# systemctl start zun-api
# systemctl start zun-wsproxy

Verify that zun-api and zun-wsproxy services are running:

# systemctl status zun-api
# systemctl status zun-wsproxy
