Description:

Ansible setup functions and aws ec2 manipulation functions for Jenkins master and agents

1、Getting Started

  • install pip and pyenv [version:2.7.9]
  • pip install ansible in pyenv
  • absoulte path: /home/ubuntu/pyenv/versions/ansible/bin
  • check ansible version: 
/home/ubuntu/pyenv/versions/ansible/bin/ansible --version
ansible 2.5.1
  config file = None
  configured module search path = [u'/home/ubuntu/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /home/ubuntu/pyenv/versions/2.7.9/envs/ansible/lib/python2.7/site-packages/ansible
  executable location = /home/ubuntu/pyenv/versions/ansible/bin/ansible
  python version = 2.7.9 (default, Apr 28 2018, 06:18:59) [GCC 4.8.4]
  • enter virtual env of ansible, you dont have use absolute path
source ~/pyenv/versions/ansible/bin/activate
  • use ansible directly

2、 Ansible files layout

ansible agent_playbook laying out roles, inventories ans playbooks

ansible-foobar/
├── cloud
│   ├── ec2.ini
│   ├── ec2.py
│   └── group_vars
├── roles
|   ├── ansible_playbook_name
|   |   |__ files --- files
|   |   |__ tasks --- main.yml
|   |   |__ templates --- tempalte
│   ├── base
|   |   |__ files --- jenkins_master_pub
|   |   |__ tasks --- main.yml
|   |   |__ templates --- 01-warning.j2
│   └── agents_name_for_setup
|   └── function_name_for_ec2
├── handlers
│   └── main.yml
├── localhost
├── site.yml
├── agent_name.yml
└── ec2_function.yaml

cloud/ec2.ini

[ec2]
# To exclude RDS instances from the inventory, uncomment and set to False.
rds = False
# To exclude ElastiCache instances from the inventory, uncomment and set to False.
elasticache = False
regions = us-east-1
destination_variable = private_dns_name
vpc_destination_variable = private_ip_address

3、Run the ansible playbook for setup

how to seup jenkins master and agent with ansible playbook

ansible-playbook -i cloud/ec2.py android_sdk_builder.yml -vvv

ansible-playbook -i cloud/ec2.py android_sdk_builder.yml

ansible-playbook -i cloud/ec2.py agents_name.yml

4、Run the ansible playbook for ec2 function

how to manipulate ec2 instance or instances with ansible playbook

/home/ubuntu/pyenv/versions/ansible/bin/ansible-playbook agents_playbook/ec2_ansible_function.yaml -i agents_playbook/localhost -t stop-one -e ONE_INSTNACE_NAME=instance_name -vvv

for example:

ansible-playbook agents_playbook/ec2_ansible_function.yaml -i agents_playbook/localhost -t tags_name  -e  additional variables as key=value -vvv
