DevOps deploy Arcadia Application - Main app¶

In this module, we will deploy the 2 main containers for Arcadia Bank application and we will publish them.

Note

At the end of this module, Arcadia Bank application will look like this.

Note

As a DevOps, you will deploy Arcadia Application (main and back end pods) with an automation tool set

Step 1 - Deploy Arcadia Main app with a CI/CD pipeline like a DevOps¶

Connect to Jumhost RDP and Login as user / user

Open Chrome, you can notice Chrome opens all the tabs for you
Login to all tools
1. Controller : admin@nginx-udf.internal / admin123!
2. Jenkins : admin / admin
3. GitLab : root / F5twister$
  
  Warning
  
  If GitLab does not start, restart the docker in the GitLab VM (WebSSH > docker restart gitlab). Wait 5 minutes.
4. Kubernetes : click on skip
5. BIG-IP : admin / admin
In Gitlab, click on Administrator / Arcadia-MainApp
1. Click on file deploy
2. Click edit and make a modification, like YES !!!!!
3. Click Commit changes

Note

At this moment, you simulate a commit like a DevOps. This commit will trigger a webhook to Jenkins, so that Jenkins executes a pipeline.

In Jenkins, click on DeployMainApp pipeline
A pipeline is running, click on it
You can follow the steps

Note

At this stage, Arcadia Main app and Back End app are deployed un K8S. But you need to publish them with NGINX+ via the controller.

Step 2 - Publish Arcadia application with NGINX+ and Controller¶

The Jenkins pipeline did several things

Deployed Arcadia application (main and back end pods) in Kubernetes
1. Connect to Kubernetes and check that.
2. You can see 2 deployments (main and back) with nodeports services

Started 3 NGINX+ instances in a docker

WebSSH to CICD and DOCKER (NGINX API gw, Dev Portal)
Run a docker ps

ubuntu@ip-10-1-1-9:~$ docker ps

Check if NGINX+ instances appears in the controller
1. In the controller GUI, click top left corner icon, and infrastructure
2. You can see 3 instances running
Deployed an AS3 declaration into the BIG-IP in order to publish the NGINX+ instance externally

Note

It is time to configure the NGINX+ instances in order to publish Arcadia application (main and back services)
