deploy to kubernetes issue

[DavidCamelo]

Hi,
I have the following configuration to deploy phpmyadmin to kubernetes.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: phpmyadmin
  labels:
    app: phpmyadmin
spec:
  replicas: 1
  selector:
    matchLabels:
      app: phpmyadmin
  template:
    metadata:
      labels:
        app: phpmyadmin
    spec:
      containers:
        - name: phpmyadmin
          image: phpmyadmin/phpmyadmin:5
          ports:
            - containerPort: 80
              protocol: TCP
          env:
            - name: PMA_HOST
              value: my-mysql
            - name: PMA_PORT
              value: "3306"
            - name: MYSQL_ROOT_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: mysql-pass
                  key: password
            - name: PMA_USER
              value: admin
            - name: PMA_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: mysql-pass
                  key: admin-password
          resources:
            limits:
              cpu: 50m
              memory: 32Mi
          imagePullPolicy: Always
      restartPolicy: Always
  strategy:
    type: RollingUpdate
  revisionHistoryLimit: 1

When the pod goes up it doesn't start the apache, I have to run service apache2 start after this I check the phpmyadmin and see that it doesn't take the environment variables defined to connect to the database

Could you help me with this problem? thanks in advance!

Hi @DavidCamelo

You need to have your instance on the same network that the database is onto to enable access via phpMyAdmin.
I hope you will find some answers in my local config: https://github.com/wdesportes/phpmyadmin-local-setup/blob/a9ac9dc281bcfa3348e4c7ad10e00ef71cbcf546/docker-compose.yml#L161 :)

Hi @williamdes

Yes, my database is on the same network, I even have wordpress deploys and java application deploys pointing to that database.

I also did a test only with docker pointing to an external database I have running on IP 54.68.2.230 and it works.
docker run --name myadmin -d -e PMA_HOST=54.68.2.230 -p 8080:80 phpmyadmin/phpmyadmin:5

I tried changing my deploy file and put only the PMA_HOST variable pointing to 54.68.2.230 but it still doesn't work

apiVersion: apps/v1
kind: Deployment
metadata:
  name: phpmyadmin
  labels:
    app: phpmyadmin
spec:
  replicas: 1
  selector:
    matchLabels:
      app: phpmyadmin
  template:
    metadata:
      labels:
        app: phpmyadmin
    spec:
      containers:
        - name: phpmyadmin
          image: phpmyadmin/phpmyadmin:5
          ports:
            - containerPort: 80
              protocol: TCP
          env:
            - name: PMA_HOST
              value: 54.68.2.230

Unfortunately I did not have the chance to try out kubernetes, It will take me some free time before I can run it on my workstation

Here is another kubernetes issue, maybe fixed.: #217

Could you open a StackOverflow (or other) question to have some better and faster help and if a bug is found in your config we could fix it afterwards ?

[DavidCamelo]

Sure I will try asking on StackOverflow, I'll keep you posted.

@williamdes FYI this is my thread in StackOverflow in case you want to follow

Hello, I also have the same problem deploying phpmyadmin to a kubernetes container. The logs are pointing to the same issue as you linked here: #217.

Here are the logs from my pod, managed by Openshift (openshift's heart is 100% kubernetes):
`/docker-entrypoint.sh: line 5: /etc/phpmyadmin/config.secret.inc.php: Permission denied

touch: cannot touch '/etc/phpmyadmin/config.user.inc.php': Permission denied

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 10.130.17.39. Set the 'ServerName' directive globally to suppress this message

(13)Permission denied: AH00072: make_sock: could not bind to address [::]:80

(13)Permission denied: AH00072: make_sock: could not bind to address 0.0.0.0:80

no listening sockets available, shutting down

AH00015: Unable to open logs
`
This comes when I try to specify different environment variables

[williamdes]

From the output the ports do not seem to bind

Hi @oscarloop, I was trying in different ways to make it work and I couldn't do it, so I'm using the bitnami phpmyadmin image
https://hub.docker.com/r/bitnami/phpmyadmin

apiVersion: apps/v1
kind: Deployment
metadata:
  name: phpmyadmin
  labels:
    app: phpmyadmin
spec:
  replicas: 1
  selector:
    matchLabels:
      app: phpmyadmin
  template:
    metadata:
      labels:
        app: phpmyadmin
    spec:
      containers:
        - name: phpmyadmin
          image: bitnami/phpmyadmin:latest
          ports:
            - containerPort: 8080
              protocol: TCP
          env:
            - name: DATABASE_HOST
              value: mysql-service

[williamdes]

They seem to re-build everything https://github.com/bitnami/bitnami-docker-phpmyadmin/blob/master/5/debian-10/Dockerfile

@J0WI do you have some ideas about this issue ?

[J0WI]

@DavidCamelo can you share the complete log output? We can only see the copying now message in #294 (comment).

[DavidCamelo]

@J0WI the log only shows the following, that's it.

phpMyAdmin not found in /var/www/html - copying now...
Complete! phpMyAdmin has been successfully copied to /var/www/html

Hi @DavidCamelo
Can you confirm it works on Kubernetes?
