Example for building an artifact using Jenkins and deploying it using Ansible

Question

Can you give an example for building an artifact using Jenkins and deploying it using Ansible? Can you describe the steps of achieving the same?

Answer 1

Hey @Harsh, follow this to get an understanding on building an artifact using Jenkins and Deploying it using Ansible.  

Install "publish Over SSH" plugin

Manage Jenkins > Manage Plugins > Available > Publish over SSH

Enable connection between Ansible and Jenkins

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

SSH Servers:

Hostname:<ServerIP>
username: username
password: *******

Test the connection "Test Connection"

create a copywarfile.yml on Ansible under /opt/playbooks

# example.yml
---
- hosts: all 
  become: true
  tasks: 
    - name: example
        copy:
          src: /op/playbooks/wabapp/target/webapp.war
          dest: /opt/apache-tomcat-8.5.32/webapps

Add tomcat server details to /etc/ansible/hosts (if you are using other hosts file update server info there)

echo "<server_IP>" >> /etc/ansible/hosts

Create Jenkins job, Fill the following details,

Source Code Management:

Repository: https://github.com/path/hello-world.git
Branches to build : */master

Build:

Root POM:pom.xml
Goals and options : clean install package

Add post-build steps

Send files or execute commands over SSH
SSH Server : ansible_server
Source fiels: webapp/target/*.war
Remote directory: //opt//playbooks

Add post-build steps

Send files or execute commands over ssh
SSH Server : ansible_server
Exec command ansible-playbook /opt/playbooks/example.yml
Execute job and you should be able to seen build has been deployed on Tomcat server.

Actually Jenkins war files were avilable under /var/lib/jenkins/workspace/.... folder right

How you got the webapp/webapp.war file under /opt/playbook folder ..

Have you written any job for copying that or you did the manually. if you did manually what is use of automation here??

or if you did it automatically, tell me the steps ..

Thanks

Hi @Venkash, I have used Ansible to automate everything here. Yes, I have used /opt/playbook as my remote working directory for Jenkins. So my war file got created here. But you can use ansible and automate the copying this file to whichever location you want.

Syntax:

    copy:
          src: Source/location
          dest: Destination/location

I am getting error while testing the connection

SSH Servers:

Hostname:<ServerIP>
username: username
password: *******

Test the connection "Test Connection"

I have following question:

1. for this example, is ansible server, tomcat and jenkins is downloaded on same server or ansible server is on different server?

2. where is this username and password ? do we have to create it in ansible and if, yes where ?

---

i) Ansible server, tomcat, and Jenkins are all downloaded on the same server.

ii) The username and password in the ssh server section is the username and the password of the host system into which you are trying to ssh. This has nothing to do with ansible. You can change the password if you have the system's root access.
