This post will show you how to install Ansible and use Ansible to create a instance EC2 in AWS.
There are several way to install Ansible. In this post, I choose the way that uses PIP to install Ansible.
If people are not laughing at your goals, your goals are too small
Install PIP, Python Boto:
|
1 |
apt-get install python-pip python-boto python-dev libffi-dev |
We need python-boto to make Ansible is able to work AWS
Install Ansible:
|
1 |
pip install ansible |
Now, we need to add AWS Access Key to make Boto can access to your AWS account:
|
1 2 |
export AWS_ACCESS_KEY_ID="your_aws_access_key" export AWS_SECRET_ACCESS_KEY="your_aws_secret_key" |
In the next step, you need create a folder for your project:
|
1 2 |
mkdir ansible-ec2 cd ansible-ec2 |
Create hosts file with the content below:
|
1 2 3 4 |
[local] localhost [minions] |
And create a provision file name ec2_launch.yml with the content:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 |

Please custom the source code above for your case with the guide:
|
1 2 3 4 5 6 7 |
vars: instance_type: t2.micro # instance type security_group: minions # AWS security group, will be created image: ami-2dad0149 # ami file for your instance region: ap-southeast-1 keypair: minions # your key pair count: 1 |
Finally, just run a command to create EC2 instance:
|
1 |
ansible-playbook -i hosts ec2_launch.yml |
If you what to run a series of commands in all the instances you created. You should create a run_test.yml file with content:
|
1 2 3 4 5 6 7 |
--- - name: Run Test Script hosts: minions tasks: - shell: echo 'test script' #should change to test script args: chdir: /home/ubuntu |
And run the test by Ansible Playbook:
|
1 |
ansible-playbook -i hosts -u ubuntu --sudo --sudo-user root run_test.yml -vvvv |
