This is what I did to resolve the issue:

1. I added these lines to my Dockerfile

   file upload

   RUN touch /usr/local/etc/php/conf.d/uploads.ini \ && echo "file_uploads = On \n\ max_execution_time = 600 \n\ upload_max_filesize = 200M \n\ post_max_size = 200M" >> /usr/local/etc/php/conf.d/uploads.ini

2. in nginx-ingress dependencies.yml,i added these 'data' parameters in the configmap and it worked.

   kind: ConfigMap apiVersion: v1 metadata: name: nginx-configuration namespace: ingress-nginx labels: app.kubernetes.io/name: ingress-nginx app.kubernetes.io/part-of: ingress-nginx data: proxy-body-size: "200m" client-max-body-size: "200m"

3. After that, *kubectl apply -f ingress/dependencies.yml* and i was able to upload more than 2mb.

Try this and see if it works for you

You can execute 'kubectl get pods' to list the pods and then get into a shell using 'kubectl exec -it [POD_NAME] -- /bin/bash'. You can then follow methods mentiond in this link to change the value.

Another option is to create a ConfigMap with your custom configuration similar to this link to increase the size of the upload file size.

Then you need to go to your GKE workloads and in “wordpress-1-wordpress” workload of type “StatefulSet” you need to modify the YAML file where you can add the ConfigMap data to a Volume.

Another workaround is that, you can rebuild the image that you are using in a docker file.

As adviced here, the recommended way is to mount a php config ini file. The most convenient way to expose it is using Kubernetes ConfigMaps. Pls create a new config map:

apiVersion: v1
kind: ConfigMap
metadata:
  name: wp-php-config
  namespace: default
data:
  uploads.ini: |-
    file_uploads = On
    upload_max_filesize = 256M
    post_max_size = 256M
    memory_limit = 64M
    max_execution_time = 600

And then expose the configMap as a volume in your pod by adding the following config to you're pod spec.template.spec.containers:

... (wordpress container specs)
  volumeMounts:
    - mountPath: /usr/local/etc/php/conf.d/uploads.ini
      name: php-config
      subPath: uploads.ini

(...)

volumes:
  - configMap:
      defaultMode: 420
      name: wp-php-config
    name: php-config

You might also need to adjust your ingress max upload limit. Assuming you're using nginx ingress, pls decorate it with an annotation:

nginx.ingress.kubernetes.io/proxy-body-size: 50m

If you want to apply the change to the ingress globally, search for the ingress configMap and add the setting there.
