Steps followed:

  1. Followed Running Magento2 in Kubernetes — Part 2: Building the Docker Image for building the docker image.
  2. Configured the values.yaml file with default values and passed the env variables values in plain text in deployment manifest file.
  3. Deployed the helm chart with the values.yaml

Please let me know if any solution for this error. Thanks

Got the fix for this error, tried couple of things:

  1. I tried to pass all the magento cloud variables via secrets.
  2. Also db host string that i was passing, magento application was not able to connect to it. Then tried to enable the helm chart mysql db and pass it's URL (svc name).
  3. Then i passed with the default params and corrected them as required.
{"database":[{"host":"mysql","path":"magento","password":"xxxxx","username":"magento","port":"3306"}],"redis":[{"host":"redis-master", "port": "6379"}],"elasticsearch":[{"host":"elasticsearch-master", "port": "9200", "scheme":"http"}],"rabbitmq":[{"host":"rabbitmq", "username":"phoenix", "password":"xxxxx", "scheme":"amqp", "port": "5672"}]}
