Customize and configure the Dashboard

Once you have the Dashboard installed, you can customize the way it
looks and feels to suit the needs of your environment, your project, or
your business.

You can also configure the Dashboard for a secure HTTPS deployment,
or an HTTP deployment. The standard OpenStack installation uses a
non-encrypted HTTP channel, but you can enable SSL support for the

For information on configuring HTTPS or HTTP, see configure_dashboard.

Customize the Dashboard

The OpenStack Dashboard on Ubuntu installs the
openstack-dashboard-ubuntu-theme package by default. If you
do not want to use this theme, remove it and its dependencies:

# apt-get remove --auto-remove openstack-dashboard-ubuntu-theme


This guide focuses on the local_settings.py file.

The following Dashboard content can be customized to suit your

  • Logo
  • Site colors
  • HTML title
  • Logo link
  • Help URL

Logo and site colors

  1. Create two PNG logo files with transparent backgrounds using the
    following sizes:

    • Login screen: 365 x 50
    • Logged in banner: 216 x 35
  2. Upload your new images to

  3. Create a CSS style sheet in

  4. Change the colors and image file names as appropriate. Ensure the
    relative directory paths are the same. The following example file shows
    you how to customize your CSS file:

    * New theme colors for dashboard that override the defaults:
    *  dark blue: #355796 / rgb(53, 87, 150)
    *  light blue: #BAD3E1 / rgb(186, 211, 225)
    * By Preston Lee <[email protected]>
    h1.brand {
    background: #355796 repeat-x top left;
    border-bottom: 2px solid #BAD3E1;
    h1.brand a {
    background: url(../img/my_cloud_logo_small.png) top left no-repeat;
    #splash .login {
    background: #355796 url(../img/my_cloud_logo_medium.png) no-repeat center 35px;
    #splash .login .modal-header {
    border-top: 1px solid #BAD3E1;
    .btn-primary {
    background-image: none !important;
    background-color: #355796 !important;
    border: none !important;
    box-shadow: none;
    .btn-primary:active {
    border: none;
    box-shadow: none;
    background-color: #BAD3E1 !important;
    text-decoration: none;
  5. Open the following HTML template in an editor of your choice:

  6. Add a line to include your newly created style sheet. For
    example, custom.css file:

    <link href='{{ STATIC_URL }}bootstrap/css/bootstrap.min.css' media='screen' rel='stylesheet' />
    <link href='{{ STATIC_URL }}dashboard/css/{% choose_css %}' media='screen' rel='stylesheet' />
    <link href='{{ STATIC_URL }}dashboard/css/custom.css' media='screen' rel='stylesheet' />
  7. Restart the Apache service.

  8. To view your changes, reload your Dashboard. If necessary, go
    back and modify your CSS file as appropriate.

HTML title

  1. Set the HTML title, which appears at the top of the browser
    window, by adding the following line to

    SITE_BRANDING = "Example, Inc. Cloud"
  2. Restart Apache for this change to take effect.

  1. The logo also acts as a hyperlink. The default behavior is to
    redirect to horizon:user_home. To change this, add the
    following attribute to local_settings.py:

    SITE_BRANDING_LINK = "http://example.com"
  2. Restart Apache for this change to take effect.

Help URL

  1. By default, the help URL points to https://docs.openstack.org. To
    change this, edit the following attribute in

    HORIZON_CONFIG["help_url"] = "http://openstack.mycompany.org"
  2. Restart Apache for this change to take effect.

Configure the Dashboard

The following section on configuring the Dashboard for a secure HTTPS
deployment, or a HTTP deployment, uses concrete examples to ensure the
procedure is clear. The file path varies by distribution, however. If
needed, you can also configure the VNC window size in the Dashboard.

Configure the Dashboard for

You can configure the Dashboard for a simple HTTP deployment. The
standard installation uses a non-encrypted HTTP channel.

  1. Specify the host for your Identity service endpoint in the
    local_settings.py file with the OPENSTACK_HOST

    The following example shows this setting:

    import os
    from django.utils.translation import gettext_lazy as _
    DEBUG = False
    PROD = True
    SITE_BRANDING = 'OpenStack Dashboard'
    # Ubuntu-specific: Enables an extra panel in the 'Settings' section
    # that easily generates a Juju environments.yaml for download,
    # preconfigured with endpoints and credentials required for bootstrap
    # and service deployment.
    # Note: You should change this value
    SECRET_KEY = 'elj1IWiLoWHgryYxFT6j7cM5fGOOxWY0'
    # Specify a regular expression to validate user passwords.
    #     "password_validator": {
    #         "regex": '.*',
    #         "help_text": _("Your password does not meet the requirements.")
    #     }
    # }
    LOCAL_PATH = os.path.dirname(os.path.abspath(__file__))
    CACHES = {
        'default': {
            'BACKEND' : 'django.core.cache.backends.memcached.MemcachedCache',
            'LOCATION' : ''
    # Send email to the console by default
    EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
    # Or send them to /dev/null
    #EMAIL_BACKEND = 'django.core.mail.backends.dummy.EmailBackend'
    # Configure these for your outgoing email host
    # EMAIL_HOST = 'smtp.my-company.com'
    # EMAIL_PORT = 25
    # EMAIL_HOST_USER = 'djangomail'
    # EMAIL_HOST_PASSWORD = 'top-secret!'
    # For multiple regions uncomment this configuration, and add (endpoint, title).
    #     ('http://cluster1.example.com/identity/v3', 'cluster1'),
    #     ('http://cluster2.example.com/identity/v3', 'cluster2'),
    # ]
    OPENSTACK_KEYSTONE_URL = "http://%s/identity/v3" % OPENSTACK_HOST
    # The OPENSTACK_KEYSTONE_BACKEND settings can be used to identify the
    # capabilities of the auth backend for Keystone.
    # If Keystone has been configured to use LDAP as the auth backend then set
    # can_edit_user to False and name to 'ldap'.
    # TODO(tres): Remove these once Keystone has an API to identify auth backend.
        'name': 'native',
        'can_edit_user': True
    # OPENSTACK_ENDPOINT_TYPE specifies the endpoint type to use for the endpoints
    # in the Keystone service catalog. Use this setting when Horizon is running
    # external to the OpenStack environment. The default is 'internalURL'.
    # The number of Swift containers and objects to display on a single page before
    # providing a paging element (a "more" link) to paginate results.
    # If you have external monitoring links, eg:

    #     ['Ganglia','http://bar.com'],
    # ]
    LOGGING = {
            'version': 1,
            # When set to True this will disable all logging except
            # for loggers specified in this configuration dictionary. Note that
            # if nothing is specified here and disable_existing_loggers is True,
            # django.db.backends will still log unless it is disabled explicitly.
            'disable_existing_loggers': False,
            'handlers': {
                'null': {
                    'level': 'DEBUG',

            'loggers': {
                # Logging from django.db.backends is VERY verbose, send to null
                # by default.
                'django.db.backends': {
                    'handlers': ['null'],
                    'propagate': False,
                'horizon': {
                    'handlers': ['console'],
                    'propagate': False,

                    'handlers': ['console'],
                    'propagate': False,
                'keystoneclient': {

    The service catalog configuration in the Identity service determines
    whether a service appears in the Dashboard. For the full listing, see

  2. Restart the Apache HTTP Server.

  3. Restart memcached.

Configure the Dashboard for

You can configure the Dashboard for a secured HTTPS deployment. While
the standard installation uses a non-encrypted HTTP channel, you can
enable SSL support for the Dashboard.

This example uses the http://openstack.example.com
domain. Use a domain that fits your current setup.

  1. In the local_settings.py file, update the following


    The other options require that HTTPS is enabled; these options defend
    against cross-site scripting.

  2. Edit the openstack-dashboard.conf file as shown in
    the Example After:

    Example Before

    WSGIScriptAlias / /usr/share/openstack-dashboard/openstack_dashboard/wsgi.py
    WSGIDaemonProcess horizon user=www-data group=www-data processes=3 threads=10
    Alias /static /usr/share/openstack-dashboard/openstack_dashboard/static/
    <Location />
      <ifVersion >=2.4>
        Require all granted
      <ifVersion <2.4>
        Order allow,deny
        Allow from all

    Example After

    <VirtualHost *:80>
      ServerName openstack.example.com
      <IfModule mod_rewrite.c>
        RewriteEngine On
        RewriteCond %{HTTPS} off
        RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
      <IfModule !mod_rewrite.c>
        RedirectPermanent / https://openstack.example.com
    <VirtualHost *:443>
      ServerName openstack.example.com
      SSLEngine On
      # Remember to replace certificates and keys with valid paths in your environment
      SSLCertificateFile /etc/apache2/SSL/openstack.example.com.crt
      SSLCACertificateFile /etc/apache2/SSL/openstack.example.com.crt
      SSLCertificateKeyFile /etc/apache2/SSL/openstack.example.com.key
      SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
      # HTTP Strict Transport Security (HSTS) enforces that all communications
      # with a server go over SSL. This mitigates the threat from attacks such
      # as SSL-Strip which replaces links on the wire, stripping away https prefixes
      # and potentially allowing an attacker to view confidential information on the
      # wire
      Header add Strict-Transport-Security "max-age=15768000"
      WSGIScriptAlias / /usr/share/openstack-dashboard/openstack_dashboard/wsgi.py
      WSGIDaemonProcess horizon user=www-data group=www-data processes=3 threads=10
      Alias /static /usr/share/openstack-dashboard/openstack_dashboard/static/
      <Location />
        Options None
        AllowOverride None
        # For Apache http server 2.4 and later:
        <ifVersion >=2.4>
          Require all granted
        # For Apache http server 2.2 and earlier:
        <ifVersion <2.4>
          Order allow,deny
          Allow from all

    In this configuration, the Apache HTTP Server listens on port 443 and
    redirects all non-secure requests to the HTTPS protocol. The secured
    section defines the private key, public key, and certificate to

  3. Restart the Apache HTTP Server.

  4. Restart memcached.

    If you try to access the Dashboard through HTTP, the browser
    redirects you to the HTTPS page.


    Configuring the Dashboard for HTTPS also requires enabling SSL for
    the noVNC proxy service. On the controller node, add the following
    additional options to the [DEFAULT] section of the
    /etc/nova/nova.conf file:

    # ...
    ssl_only = true
    cert = /etc/apache2/SSL/openstack.example.com.crt
    key = /etc/apache2/SSL/openstack.example.com.key

    On the compute nodes, ensure the nonvncproxy_base_url
    option points to a URL with an HTTPS scheme:

    # ...
    novncproxy_base_url = https://controller:6080/vnc_auto.html
