raxservers

create, resize, delete rax servers

1-Spin up a vagrant box

$ mkdir vagrant_test //or what ever name
$ cd vagrant_test
$ vagrant init ubuntu/trusty64;
$ vagrant up
$ vagrant ssh

Note:

• after vagrant init it added a VagrantFile, edit VagrantFile to sync source code from local machine
• after access vm box (vagrant ssh), you may need to create ~/data and ~/sox directories to hold source codes and data files.

# example add line to sync source to vm
config.vm.synced_folder "~/rax-servers/src/", "/home/vagrant/sox/"

# you may need to increate memory from vm (by default 1024MB) to 2048MB
config.vm.provider "virtualbox" do |vb|
...
  # Customize the amount of memory on the VM:
  # vb.memory = "1024"
  vb.customize ["modifyvm", :id, "--memory", "2048"]
end

2-create ansible_hosts

$ echo "127.0.0.1" > ~/ansible_hosts  
$ export ANSIBLE_HOSTS=~/ansible_hosts
$ export ANSIBLE_HOST_KEY_CHECKING=false

3-update ~/.raxpub (template in src) folder with user credential

4-install some missing package if need

$ sudo apt-get update
$ sudo apt-get install python-pip python-dev build-essential
$ sudo pip install --upgrade pip

5-run install ansible_requirements.txt from src folder

$ sudo pip install -r ansible_requirements.txt

6-check ansible version

$ ansible --version

7-setup authorization key

$ ssh-keygen -t rsa
$ cp ~/.ssh/id_rsa.pub ~/.ssh/authorized_keys (make sure you don't overwrite the existing keys in authorized_keys)

8-test: from sox/ dir

$ ansible all -m ping -i inventory/
  127.0.0.1 | success >> {
    "changed": false, 
    "ping": "pong"
  }

9-modify inventory/testgroup1/master/group_vars/all file to change flavor or image of servers want to create

10-run playbook: from sox/ directory

create servers:

$ ansible-playbook sox_compliance/create.yml -i inventory/testgroup1/master/ -vvvv

or can use with --extra-vars (do the same for resize and delete servers)

$ ansible-playbook sox_compliance/create.yml -i inventory/testgroup1/master/ --extra-vars "prefix=testgroup1uk region=LON" -vvvv

• Notes: to create uk server using LON region have to use uk account credential. resize servers:

$ ansible-playbook sox_compliance/update.yml -i inventory/testgroup1/master/ -vvvv

delete servers:

$ ansible-playbook sox_compliance/delete.yml -i inventory/testgroup1/master/ -vvvv

Note:

• Because ansible adds keys to known_hosts, and Rackspace rotates IPs, you might come across ip contentions. If so, just clean out your known_hosts file.

~/.ssh/known_hosts
