This project has Ansible code for performing 'Post OS-installation' configurations on Electric Cloud servers running Ubuntu 16.04.

Skip to Running the playbook

1. Server should have OS deployed (Ubuntu 16.04.3)
2. Server should be on network
3. Hostname should be registered in DNS
4. SSH should be open for root

1. Clone this repo

$ git clone [email protected]:cloudops/ea_ubuntu16.git

2. Use pre-installed repo on qnc-eng-ansible

[user@qnc-eng-ansible ~:]$ cd /home/projects/all/ea_ubuntu16
[user@qnc-eng-ansible /home/projects/all/ea_ubuntu16]$

Run all commands from the above path /home/projects/all/ea_ubuntu16

Running playbooks against one or more servers is easy. Just follow the steps.

Use your favorite editor to edit the inventory file (hosts.ini) and add your host(s) to appropriate host-group(s). As of now there are four different host-groups as listed below, two for each GEO.

1. Bangalore

• electric_cloud_ub16_emake_servers_bng
• electric_cloud_ub16_agent_servers_bng

2. Quincy

• electric_cloud_ub16_emake_servers_qnc
• electric_cloud_ub16_agent_servers_qnc

You need to figure out the GEO and type (emake or agent) for each server and add them under the appropriate host-group(s).

Before you run the playbook it is always a good idea to check if the servers that you just added are showing up in with the --list-hosts option.

$ ./electric_cloud_ub16.yml -i hosts.ini --list-hosts --limit qnc-ea-agt-104*

playbook: ./electric_cloud_ub16.yml

  play #1 (electric_cloud_ub16_servers): electric_cloud_ub16_servers    TAGS: []
    pattern: [u'electric_cloud_ub16_servers']
    hosts (4):
      qnc-ea-agt-104d
      qnc-ea-agt-104a
      qnc-ea-agt-104c
      qnc-ea-agt-104b
$

Note the use of ---limit (-l is its short form) option. This helps in listing the hosts the you are intersted in.
You can separate the list of hosts with commas(,) for example

$ ./electric_cloud_ub16.yml -i hosts.ini --list-hosts -l qnc-emake-32a,qnc-emake-32b,qnc-ea-agt-104*

Once you are sure of the list of servers against which the playbook would run, use the following command to run the playbook.
Note: You should be able to login to the target server with root (either with password or with ssh-keys) from your Ansible machine, before you run the playbook

$ ./electric_cloud_ub16.yml -i hosts.ini --list-hosts --limit qnc-ea-agt-104a
SSH password:

Once the playbook run is complete, the target server(s) would have the desired configurations in place and the requisite packages installed. Note: The playbook is idempotent, i.e. multiple runs of the playbook would result in same state of the target server(s).
