Custom theme / plugins running on Kubernetes

[oxodesign]

Hi everyone,

I got things running correctly and as I want using Docker Compose but when it comes to our test server (Kubernetes) im having issues with permission on /var/www/html folder.

I tried copying things to /usr/src/wordpress but it looks like this only works on first install! Changes that has been done on the theme are not being updated.

So can someone explain (as for dummies, step by step) how to get this up and running, my docker using Dockerfile?

My Dockerfile looks like this (very minimal):

FROM wordpress:latest

COPY php/ext/upload.ini /usr/local/etc/php/conf.d/upload.ini
COPY wp-content/ /var/www/html/wp-content

All help is appreciated

Thanks in advance

The entrypoint just copies /usr/src/wordpress to /var/www/html and essentiallty chown's its contents

wordpress/latest/php8.0/apache/docker-entrypoint.sh

Lines 38 to 42 in 1d90641

	sourceTarArgs=(
	--create
	--file -
	--directory /usr/src/wordpress
	--owner "$user" --group "$group"

For the Debian variant you'll want to grant permissions on the volume you're mounting for UID 33 (www-data in the container), if you're using Alpine then UID 82
Also you can run the image as an arbitrary user https://github.com/docker-library/docs/tree/master/wordpress#running-as-an-arbitrary-user

You could also try asking over at the Docker Community Forums, Docker Community Slack, or Stack Overflow. Since these repos aren't really a user-help forum

Thanks a lot for you reply, still dont have a clue how to do this! And probably this is very easy but I still dont understand to do this. Will appriciate if you provided with a simple Dockerfile on how to do this but understand if you dont want/have time.

Btw I asked Docker Slack and Kubernetes Slack without any help :(

@oxodesign
First, you need to find out from which user uid apache or php-fpm is running in k8s (33/82/etc?)
You can add InitContainer to your deployment.yaml. Which will move the folder to the right place for WP and assign the owner/rights (chown/chmod)
See - https://kubernetes.io/docs/concepts/workloads/pods/init-containers/

I'm having the same issues !
I tried to do this : COPY ./app/wp-content/themes /usr/src/wordpress/wp-content/themes
then this : COPY ./app/wp-content/themes/my-theme /usr/src/wordpress/wp-content/themes

But still not working on Kubernetes
