I have php laravel applicaiton running on EKS, I have 3 nodes and 3 pods on each node.

The application works fine, I recently wanted to install newrelic, I found some instructions and added them to docker file.

ENV NR_INSTALL_SILENT=1
ENV NR_INSTALL_USE_CP_NOT_LN=1

RUN apk add --no-cache bash

# Install New Relic, i can see this ini file with licence key being coppied properly
COPY deployment/newrelic.ini /tmp/newrelic.ini

RUN curl -sSL https://download.newrelic.com/php_agent/archive/10.20.0.10/newrelic-php5-10.20.0.10-linux.tar.gz | tar xzf - -C /tmp

RUN chmod +x /tmp/newrelic-php5-10.20.0.10-linux/newrelic-install && 
    ls -al /tmp/newrelic-php5-10.20.0.10-linux/ 

RUN /bin/bash -c "/tmp/newrelic-php5-10.20.0.10-linux/newrelic-install install"

I have tried to install without bash too, I have tried all possible combinations, but it always downloads and extracts the newrelic but the last command with install does not work.

I can go inside the pod and if i run that command without doing anything, it does installation properly and i can see .so file after that by running

find / -name "newrelic.so" 2>/dev/null

I have echoed and checked, the env variables are there with correct values, and the only thing i am unable to understand that why it works manually and does not throw any error, even if i say

RUN /tmp/newrelic-php5-10.20.0.10-linux/newrelic-install install > /tmp/newrelic_install.log 2>&1

I do not get anything in log file, so i am unable to understand what do i need to do to run this command? what i am doing wrong?
