<p>I have deployed MySql and PhpMyAdmin in Kubernetes cluster. I want to log in to PMA with the username and password and connect to Mysql. I kind of got stuck. I have external IP for PMA which should connect to my database.
Here is my deployment script:</p>

<p>For mysql:</p>

<pre><code>apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    name: mysqldb
  name: mysqldb
spec:
  replicas: 1
  strategy:
    type: Recreate
  template:
    metadata:
      creationTimestamp: null
      labels:
        name: mysqldb
    spec:
      containers:
      - env:
        - name: DB_NAME
          value: metrics
        - name: DB_USER
          value: metrics
        - name: DB_PASS
          value: ****
        image: mysql:5.7
        name: mysqldb
        ports:
        - containerPort: 3306
        resources: {}
        volumeMounts:
        - mountPath: /var/lib/mysql
          name: data-volume
          subPath: data
      restartPolicy: Always
      volumes:
      - name: data-volume
        persistentVolumeClaim:
          claimName: data-volume
status: {}
</code></pre>

<p>For PMA:</p>

<pre><code>apiVersion: v1
kind: Pod
metadata:
  name: myadmin
  labels:
    name: myadmin
spec:
  containers:
    - name: phpmyadmin
      image: phpmyadmin/phpmyadmin
      env:
        - name: PMA_HOST
          value: mysqldb
        - name: DB_NAME
          value: metrics
        - name: DB_USER
          value: *****
        - name: DB_PASS
          value: *****
      ports:
        - containerPort: 80
          name: myadmin
</code></pre>

<p>Am I doing something wrong.</p>

<p>Is it even possible to deploy Php, Mysql, PMA, React and Nginx all in Kubernetes?
Kind of struggling to figure-out how all things are connected and can't find any meaningful resources related to this topic. My app works fine in local machine with docker-compose and trying to convert this file to Kompose resources.</p>

<p>Here is my docker-compose file: </p>

<p>I would appreciate if you can help. Thanks!</p>

<p>The way to do it is:</p>

<ol>
<li>Stateful set with PHP My Admin</li>
<li>Service pointing to stateful set</li>
<li>Ingress pointing to the service</li>
<li>your MySQL Stateful set</li>
</ol>
