Secret Demo

1. Create a secret from file mysecret

   apiVersion: v1
   kind: Secret
   type: Opaque
   metadata:
       name: mysecret
   data:
       # Using root password: Password123
       MYSQL_ROOT_PASSWORD: UGFzc3dvcmQxMjM=
       # Using user password: Password1234
       MYSQL_PASSWORD: UGFzc3dvcmQxMjM0 
       MYSQL_DATABASE: ZGF0YTE= 
       MYSQL_USER: bWFoZW5kcmE=     

   Now, run following commands:

   $ kubectl apply -f ./mysecret.yml
   $ kubectl describe -f ./mysecret.yml

2. Create a pod that uses Secret pod

   apiVersion: v1
   kind: Pod
   metadata:
       name: pod4
       labels:
           name: web4
   
   spec:
   containers:
   -   name: db1
       image: mysql:5.7
       envFrom:
           - secretRef:
               name: mysecret
       resources:
           limits:
           memory: "1Gi"
           cpu: "500m"
       ports:
           - containerPort: 3306
   -   name: test
       image: mahendrshinde/mysql-client:latest
       imagePullPolicy: IfNotPresent
       command: ["sh", "-c", "echo Hello World && sleep 3600"]
       resources:
           limits:
           memory: "64Mi"
           cpu: "100m"

   Now, run following commands:

   $ kubectl apply -f ./pod-4.yaml
   $ kubectl get pods

3. Once, pod status for "pod4" chages to RUNNING, try entering inside the pod.

   $ kubectl exec pod4 -c test -it sh  
   # try connecting mysql server (Use loopback ip or pod name)
   $ mysql -umahendra -pPassword@1234 -h pod3
   $ exit
   $ exit

4. Delete the resources

   $ kubectl delete -f pod-4.yaml
   $ kubectl delete -f mysecret.yml
