Install and configure a compute node for Ubuntu

Install and configure a compute node for Ubuntu

This section describes how to install and configure the Kuryr-libnetwork for Ubuntu 16.04 (LTS).

Prerequisites

This guide assumes Docker is already installed. Refer Get Docker for Docker installation.

Install and configure components

  1. Create kuryr user and necessary directories:

    • Create user:

      # groupadd --system kuryr
      # useradd --home-dir "/var/lib/kuryr" \
            --create-home \
            --system \
            --shell /bin/false \
            -g kuryr \
            kuryr
      
    • Create directories:

      # mkdir -p /etc/kuryr
      # chown kuryr:kuryr /etc/kuryr
      
  2. Clone and install kuryr-libnetwork:

    # apt-get install python-pip
    # cd /var/lib/kuryr
    # git clone https://git.openstack.org/openstack/kuryr-libnetwork.git
    # chown -R kuryr:kuryr kuryr-libnetwork
    # cd kuryr-libnetwork
    # pip install -r requirements.txt
    # python setup.py install
    
  3. Generate a sample configuration file:

    # su -s /bin/sh -c "./tools/generate_config_file_samples.sh" kuryr
    # su -s /bin/sh -c "cp etc/kuryr.conf.sample \
          /etc/kuryr/kuryr.conf" kuryr
    
  4. Edit the /etc/kuryr/kuryr.conf:

    • In the [DEFAULT] section, configure the path for the Kuryr vif binding executables:

      [DEFAULT]
      ...
      bindir = /usr/local/libexec/kuryr
      
    • In the [neutron] section, configure Identity service access:

      [neutron]
      ...
      auth_uri = http://controller:5000
      auth_url = http://controller:35357
      username = kuryr
      user_domain_name = default
      password = KURYR_PASSWORD
      project_name = service
      project_domain_name = default
      auth_type = password
      

      Replace KURYR_PASSWORD with the password you chose for the kuryr user in the Identity service.

  5. Create an upstart config, it could be named as /etc/systemd/system/kuryr-libnetwork.service:

    [Unit]
    Description = Kuryr-libnetwork - Docker network plugin for Neutron
    
    [Service]
    ExecStart = /usr/local/bin/kuryr-server --config-file /etc/kuryr/kuryr.conf
    CapabilityBoundingSet = CAP_NET_ADMIN
    
    [Install]
    WantedBy = multi-user.target
    

Finalize installation

  1. Enable and start the kuryr-libnetwork service:

    # systemctl enable kuryr-libnetwork
    # systemctl start kuryr-libnetwork
    
  2. After Kuryr starts, please restart your Docker service:

    # systemctl restart docker
