Ansible JWS demo

This playbook demonstrate how to install and upgrade Apache Tomcat (or JBoss Web Server) and also deploy and update a webapp using Ansible.

How to use devfile to setup your dev environment

To use the devfile.yaml and set up your development environment with OpenShift Dev Spaces or Visual Studio Code, follow these steps:

1. Clone the Repository

   git clone https://github.com/ansible-middleware/jws-app-update-demo.git
   cd jws-app-update-demo

2. Install OpenShift Dev Spaces or Visual Studio Code

   • Download and install OpenShift Dev Spaces, else you can directly use Dev Spaces from Red Hat Developer Snadbox as well.
   • Download and install Visual Studio Code.
3. 1. Open the Red Hat Dev Spaces(If you Red Hat subscription use this)
   • Select Red Hat Dev Spaces option from above provided Red hat Developer Sandbox link.
   • Put jws-app-update-demo Git repo URL in the Import from Git option and click on Create & Open.
   2. Open the Project in Visual Studio Code
   • Open Visual Studio Code.
   • Open the project folder you cloned: File > Open Folder... and select the project directory.
   • Once the folder is open, click on the green button in the bottom-left corner (><) and select New Dev Container.

Both options will use the devfile.yaml to configure and start the development container. You can then start coding and run the playbook within this environment, without worrying about the prerequisite setup.

Requirements

This demo has been tested on a RHEL 8.4 system using Ansible 2.9.22 (as provided by Red Hat) running wit Python3.

$ ansible-galaxy collection install middleware_automation.jws

This collection is available on Automation Hub. For Ansible Galaxy to be able to download, the ansible.cfg needs to be configured to use it:

TODO

Alternatively, you can use the upstream version of this collection (you'll need to adapt the provided playbooks):

$ ansible-galaxy collection install middleware_automation-jws-0.0.1.tar.gz
Process install dependency map
Starting collection install process
Installing 'middleware_automation.jws:0.0.1' to '/root/.ansible/collections/ansible_collections/middleware_automation/jws'
Installing 'middleware_automation.redhat_csp_download:1.1.1' to '/root/.ansible/collections/ansible_collections/middleware_automation/redhat_csp_download

Run the demo

Then run Ansible to install JWS and the demo app:

$ ansible-playbook install_jws_and_webapp.yml

To update the application, run again Ansible:

$ ansible-playbook -e app_version=1.1 install_jws_and_webapp.yml

To downgrade the application, run again Ansible:

$ ansible-playbook -e app_version=1.0 install_jws_and_webapp.yml
