Error establishing a database connection

[ghost]

I deployed this per the instruction on a new cluster as well as on minikube. But in both cases, when I access wordpress deployed, I got the the following displayed on the browser screen:

Warning: A non-numeric value encountered in /var/www/html/wp-config.php on line 29
Warning: A non-numeric value encountered in /var/www/html/wp-config.php on line 29
Warning: A non-numeric value encountered in /var/www/html/wp-config.php on line 29
Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/wp-config.php:29) in /var/www/html/wp-includes/functions.php on line 3790
Error establishing a database connection

How to fix it?

Can you post your wp-config.php? Seems like a config error rather than something wrong with your approach.

Hello,
maybe old issue but:
1.
try create on mysql pod:
mysql -u root -p
mysql> CREATE DATABASE wordpress;

2. Add in wordpress-deployment.yaml additional env with user for DB
   env:
   - name: WORDPRESS_DB_USER
   value: "root"

for me worked

The comment above worked for me.
