This is collaboration between Cumulus and BlueJeans to automate a Datacenter network.

The goal is to deploy a clos network utilizing ONIE to install system images on the network switches, ZTP to setup a baseline config (deploy ssh keys), and finally Ansible to push the actual network configurations (PTM, IP, BGP, etc)

#Files:

• role/config-isc-dhcp-server/files/dhcpd.conf: dhcp file used on the RMP managment switch
• role/mgmt-switch-networking/templates/hosts.j2: host file for OOBM Management switch
• role/apache2/files/ztp-deploy.sh: Zero touch provisioning script which opies license file, and authorized public key for Ansible.
• Vagrant/Vagrantfile: Vagrant definition to stand up virtual network

#Automated install instructions: ###Become root and install ansible and git

sudo -i
apt-get update
apt-get install -y python-pip git python-dev gcc python-apt
pip install ansible; pip install ansible --upgrade

###Clone the git repo locally and cd into the dc1 directory:

git clone https://github.com/CumulusNetworks/bluejeans
cd bluejeans/dc1/

###Run management.yml ansible playbook ansible-playbook management.yml

###Deploy ssh keys

ansible-playbook deploy-ssh-keys.yml -kK

###Run the full playbooks Make sure to use the --extra-vars flag to set vagrant=yes. Leave off the statement if vagrant isn't being used (i.e. running ansible on production). Currently the flag removes switch/ports.conf and doesn't restart switch (switchd does't exist in VX), and it adds in the eth1 interface that allows for dhcp using the "RMP like" VX switch. ansible-playbook main.yml -e vagrant=yes

#Manual install instructions ###Connect to the management VM vagrant ssh management

###Change to root vagrant@management:~$ sudo -i

root@management:~#

• echo -e "deb http://ftp.us.debian.org/debian/ wheezy main contrib non-free\ndeb-src http://ftp.us.debian.org/debian/ wheezy main contrib non-free" >> /etc/apt/sources.list
• apt-get update
• apt-get install -y isc-dhcp-server dnsmasq apache2
• apt-get install -y python-pip shedskin libyaml-dev sshpass git python-netaddr
• pip install ansible
• pip install ansible --upgrade

###Setup git and download the repo

root@management:~#

• git init
• git config --global user.name "Your Name"
• git config --global user.email [email protected]
• git clone https://github.com/CumulusNetworks/bluejeans

###Validate OOB connection on the management switch root@management:~#

• cp ~/bluejeans/dc1/management/etc/network/interfaces /etc/network/interfaces
• service networking restart

###Setup DNS

• cat ~/bluejeans/dc1/management/etc/hosts >> /etc/hosts
• service dnsmasq restart

###Setup DHCP

• cp ~/bluejeans/dc1/management/etc/dhcp/dhcpd.conf /etc/dhcp/dhcpd.conf
• cp ~/bluejeans/dc1/management/etc/dhcp/dhcpd.hosts /etc/dhcp/dhcpd.hosts
• cp ~/bluejeans/dc1/management/etc/dhcp/dhcpd.pools /etc/dhcp/dhcpd.pools
• service isc-dhcp-server restart

###Validate connectivity Change into the ~/bluejeans/dc1 directory to run the Ansible playbooks

root@management:~# cd bluejeans/dc1

• root@management:~/bluejeans/dc1#
• ansible all -m ping -u cumulus -k
  • (pwd: CumulusLinux!)

###Setup SSH keys and deploy to the network

• ssh-keygen -t rsa
• cp /root/.ssh/id_rsa.pub /var/www/authorized_keys
• cp ~/bluejeans/dc1/var/www/ztp_deploy.sh /var/www/
• ansible-playbook deploy_ssh_keys.yml --ask-become-pass -k
  • (pwd: CumulusLinux!)

###Run the full playbooks Make sure to use the --extra-vars flag to set vagrant=yes. Leave off the statement if vagrant isn't being used (i.e. running ansible on production). Currently the flag removes switch/ports.conf and doesn't restart switch (switchd does't exist in VX), and it adds in the eth1 interface that allows for dhcp using the "RMP like" VX switch.
