413 Request Entity Too Large on Wordpress / Kubernetes - wordpress

Question

When trying to upload a new theme on my fresh Wordpress install, I get the 413 Request Entity Too Large.
I've read a lot of other questions on StackOverflow and tried these annotations:
nginx.ingress.kubernetes.io/secure-backends: "true"
nginx.ingress.kubernetes.io/proxy-body-size: "100m"
nginx.ingress.kubernetes.io/client-max-body-size: "100m"
nginx.org/client-max-body-size: "100m"
What works:
Uploading files smaller than 1MB.
I guess it has to do with the Bitnami standard nginx configuration. As seen here . But I have no clue on how to add this to my current configuration.
Thanks for helping me out!

Answer 1

If you were using an external Nginx Ingress Controller you would create a configmap for your ingress controllers and set the proxy-body-size to the size needed.
The default size for it is 1m
There is also a bitnami wordpress nginx image
Where you can set the Server block for it directly and add client_max_body_size
https://github.com/bitnami/bitnami-docker-wordpress-nginx/blob/master/test.yaml#L9

Thanks for your comment strongjz!
The one line of code that was needed to solve this problem was:
ingress.bluemix.net/client-max-body-size: "500m"
Once I've added this to the annotations of my ingress. The issue was solved!
