### Implementation Steps

1. Jenkins Installation and Configuration - jenkins server1

- Deployed jenkins server as an azure vm via terraform that uses a remote-exec provisioner for automation / bootstrapping

- Generate ssh key pair on local machine ( done before deploying jenkins )

ssh-keygen -m PEM -t rsa -b 4096

Location of key pair: under C:\Users\The Cosmos\.ssh

To view these files:

cat ~/.ssh/id_rsa.pub
cat ~/.ssh/id_rsa

Login: Rahul using private key .ppk

===========================================================================================================================================================

2. Create ACR and AKS Cluster via terraform

=========================================================================================================================================================

3. HELM Installation and Configuration ( for jenkins user )

su - jenkins
curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
chmod 700 get_helm.sh
./get_helm.sh

Verify:

jenkins@jenkins-server1:~$ helm version
version.BuildInfo{Version:"v3.10.0", GitCommit:"ce66412a723e4d89555dc67217607c6579ffcb21", GitTreeState:"clean", GoVersion:"go1.18.6"}

> Configure HELM

jenkins@jenkins-server:~$ mkdir .kube
jenkins@jenkins-server:~$ cd .kube
jenkins@jenkins-server:~/.kube$ pwd
jenkins@jenkins-server:~/.kube$ vi config
jenkins@jenkins-server:~/.kube$ chmod 600 config
jenkins@jenkins-server:~/.kube$ helm list
NAME    NAMESPACE       REVISION        UPDATED STATUS  CHART   APP VERSION

=========================================================================================================================================================

4. Creating a helm chart for python restapi

### Creating a helm chart called python-restapi-chart under /var/lib/jenkins ie home dir of jenkins user ( created by default post installation )

1. Create a folder structure

jenkins@jenkins-server1:~$ helm create test
jenkins@jenkins-server1:~$ cd test/
jenkins@jenkins-server1:~/test$ ls -l
total 16
-rw-r--r-- 1 jenkins jenkins 1140 Sep 26 20:27 Chart.yaml
drwxr-xr-x 2 jenkins jenkins 4096 Sep 26 20:27 charts
drwxr-xr-x 3 jenkins jenkins 4096 Sep 26 20:27 templates
-rw-r--r-- 1 jenkins jenkins 1871 Sep 26 20:27 values.yaml
jenkins@jenkins-server1:~/test$ cd templates/
jenkins@jenkins-server1:~/test/templates$ ls -l
total 32
-rw-r--r-- 1 jenkins jenkins 1735 Sep 26 20:27 NOTES.txt
-rw-r--r-- 1 jenkins jenkins 1752 Sep 26 20:27 _helpers.tpl
-rw-r--r-- 1 jenkins jenkins 1821 Sep 26 20:27 deployment.yaml
-rw-r--r-- 1 jenkins jenkins  907 Sep 26 20:27 hpa.yaml
-rw-r--r-- 1 jenkins jenkins 2073 Sep 26 20:27 ingress.yaml
-rw-r--r-- 1 jenkins jenkins  352 Sep 26 20:27 service.yaml
-rw-r--r-- 1 jenkins jenkins  314 Sep 26 20:27 serviceaccount.yaml
drwxr-xr-x 2 jenkins jenkins 4096 Sep 26 20:27 tests

2. Edit the name parameter in Chart.yaml to python-restapi-chart

jenkins@jenkins-server1:~/test$ cat Chart.yaml | grep name
name: python-restapi-chart

3. View helm chart

jenkins@jenkins-server1:~$ helm show chart test
apiVersion: v2
appVersion: 1.16.0
description: A Helm chart for Kubernetes
name: python-restapi-chart
type: application
version: 0.1.0

=========================================================================================================================================================

5. Follow word document to setup the pipelines
