Cannot reach mapserver in kubernetes cluster when upgrade from 7.4 to 8.0

[mizzPpY]

Hi,
I was using camptocamp/mapserver:7.4 image deploy on kubernetes cluster, it was working fine regardless the cluster is on a virtual machine or on aws.
But when updating to 8.0, start to encounter issue when deploy on aws. How I test is to curl http://localhost; previously it is returning response "No query information to decode. QUERY_STRING is set, but empty.", but with mapserver 8.0 it return status 500.

Not sure if it helps but the following is the logs from the container upon start up:

Switching listen port to 80

My Dockerfile:

FROM camptocamp/mapserver:8.0

# Install gettext to use envsubst command container post-startup 
RUN apt-get update && apt install -y --no-install-recommends gettext 

# Copy my custom .map file into /etc/mapserver
WORKDIR /etc
COPY map/*.map mapserver/

WORKDIR /etc/mapserver
