Option A: Edit php.ini

// Case: Kubernetes Pod / Docker Container
containerName=sexcenter-wordpress-6f59c9fbff-5b99h
kubectl exec --stdin --tty $containerName -- /bin/bash

// Check execution time
grep max_execution_time /opt/bitnami/php/etc/php.ini

// Change execution time duration to 1 hour
sed -i '/max_execution_time/c\max_execution_time = 3600' /opt/bitnami/php/etc/php.ini

// Check memory limit
grep memory_limit /opt/bitnami/php/etc/php.ini

// Set memory limit to 20GB
sed -i '/memory_limit/c\memory_limit = 20G' /opt/bitnami/php/etc/php.ini

// Change execution time duration and memory to unlimited (for testing purposes)
sed -i '/max_execution_time/c\max_execution_time = 999999' /opt/bitnami/php/etc/php.ini
sed -i '/memory_limit/c\memory_limit = -1' /opt/bitnami/php/etc/php.ini
