Install Ansible on Amazon EC2


  • Amazon Linux EC2 Instance

Installation steps

Install python and python-pip

[root@Ansible_host ~]# yum install python
[root@Ansible_host ~]# yum install python-pip

Using pip command install Ansible

[root@Ansible_host ~]# pip install ansible
[root@Ansible_host ~]# ansible --version

Create a user called for Ansible

[root@Ansible_host ~]# useradd ansibleadmin
[root@Ansible_host ~]# passwd ansibleadmin

grant sudo access to ansibleadmin user.

[root@Ansible_host ~]# echo "ansibleadmin ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

Login ansibleadmin user and generate key


Copy keys to the target server.

Ansible server used to create images and store them on the docker registry.

yum install docker
service docker status
service docker start
usermod -aG docker ansibleadmin

Create a folder /opt/ansible and hosts file for inventory file add control node and manged hosts IP address to it.

Validating test Ansible

Run ansible command as ansibleadmin user.

ansible all -m ping

How to integrate Ansible with Jenkins

You need to Install “publish Over SSH” as below

Manage Jenkins > Manage Plugins > Available > Publish over SSH

Enable connection between Ansible-control-node and Jenkins as below.

Manage Jenkins > Configure System > Publish Over SSH > SSH Servers


  • SSH Servers:
  • Name: ansible-server
  • Hostname:<ServerIP>
  • username: ansibleadmin
  • Click Advanced > chose Use password authentication, or use a different key.

Create an Ansible playbook

I will create a simple Ansible playbook as below

- hosts:
  become: true
  - name: Stop old docker container
    command: docker stop devops-container
    ignore_errors: yes

  - name: Remove stopped docker container
    command: docker rm devops-container
    ignore_errors: yes

  - name: Remove current docker image
    command: docker rmi devops-image
    ignore_errors: yes

  - name: Building docker image
    command: docker build -t devops-image .
      chdir: /opt/docker

  - name: creating docker image
    command: docker run -d --name devops-container -p 8080:8080 devops-image

Run Ansible playbook

ansible-playbook -i hosts simple-devops.yml
