I created an EC2 Instance (Ubuntu) and named it Jenkins-Ansible. We will use this server to run playbooks.
I opened custom TCP port 8080 on the instance security group
Next, I created a new repository in my GitHub account and named it ansible-config-mgt
The next step was to install Ansible and Jekins on the Jenkins-Ansible server
sudo apt update
sudo apt install default-jdk-headless
wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -
sudo sh -c 'echo deb https://pkg.jenkins.io/debian-stable binary/ > \
/etc/apt/sources.list.d/jenkins.list'
sudo apt update
sudo apt-get install jenkins
###Make sure Jenkins is up and running
sudo systemctl status jenkins
On the Jenkins server, I opened TCP port 8080 by creating a new Inbound Rule in the EC2 Security Group Security Group settings
Jenkins url is http://52.56.227.233:8080/
sudo apt update
sudo apt install ansible
Ansible version
ansible --version
ubuntu@ip-172-31-25-140:~$ sudo apt install ansible

ansible 2.10.8
config file = None
configured module search path = ['/home/ubuntu/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python3/dist-packages/ansible
executable location = /usr/bin/ansible
python version = 3.10.4 (main, Apr 2 2022, 09:04:19) [GCC 11.2.0]
The next step is to configure Jenkins build job to save the repository content every time it changes.
I created a new Freestyle project ansible in Jenkins and pointed it to the ‘ansible-config-mgt’ repository.
I Configured Webhook in GitHub and set webhook to trigger the ansible build.
Next, I configured a Github hook trigger for GITScm polling and a Post-build job in Jenkins to save all (**) files
check that artifacts (6th build) are stored on the jenkins server
ls /var/lib/jenkins/jobs/ansible/builds/6/archive/
###The next step was to prepare the Development Environment using VSC
Then I proceeded to clone the github repository
I confirmed I was in the correct git branch (main) in VSC using gitbash
git branch
projectx Next I checked the git status
`` git status
[Git status](https://missafricagb.com/git/git-status.JPG)
I then created a new branch and named it projectx
git checkout -b projectx
[New branch](https://missafricagb.com/git/branch-projectx.JPG)
I created a directory and named it playbooks – it will be used to store all the playbook files.
mkdir playbooks ``
I also created a directory and named it inventory – it will be used to keep the hosts organised.
mkdir inventory
Within the playbooks folder, I created the first playbook, and named it common.yml
touch playbooks/common.yml
Within the inventory folder, I created an inventory file (.yml) for each environment (Development, Staging Testing and Production) dev, staging, uat, and prod respectively.
touch inventory/dev.yml inventory/staging.yml inventory/uat.yml inventory/prod.yml
This will define the hosts and group of hosts upon which the playbook commands will operate.
Next I set up the ssh-agent
eval `ssh-agent -s`
ssh-add darey-io-keypair.pem
I confirmed that the key had been added with the command ssh-add -l
ssh-add -l
I then connected to the jenkins server using the ssh agent and the servers public IP4 address
ssh -A [email protected]
I updated inventory/dev.yml with this snippet of code setting each server's private IP as host
[nfs]
172.31.24.237 ansible_ssh_user='ec2-user'
[webservers]
172.31.19.173 ansible_ssh_user='ec2-user'
172.31.27.39 ansible_ssh_user='ec2-user'
[db]
172.31.27.141 ansible_ssh_user='ec2-user'
[lb]
172.31.29.165 ansible_ssh_user='ubuntu'
** Step 5 – Create a Common Playbook This will give Ansible the instructions on what you needs to be performed on all servers listed in inventory/dev.
I updated playbooks/common.yml file with following code:
---
- name: update web, nfs and db servers
hosts: webservers, nfs, db
remote_user: ec2-user
become: yes
become_user: root
tasks:
- name: ensure wireshark is at the latest version
yum:
name: wireshark
state: latest
- name: update LB server
hosts: lb
remote_user: ubuntu
become: yes
become_user: root
tasks:
- name: Update apt repo
apt:
update_cache: yes
- name: ensure wireshark is at the latest version
apt:
name: wireshark
state: latest
**Step 6 – Update GIT with the latest code The next step was to push the directories and files on the local machine to GitHub.
git status
git add .
git commit -m "Commit updated local folders and files"
git push origin projectx
React
Typescript
Django
Laravel
Facebook
Microsoft
Google
Alibaba
