Can anyone please let me know if anything missing

Answer 1

The error indicates that Alpine apk package management tool wasn't able to install curl, fontconfig and other packages due to not being able to connect to http://dl-cdn.alpinelinux.org/alpine/v3.9/main/x86_64/ host and get the files from there.

Ensure that your host machine has Internet and if it does follow recommendations from the My docker container has no internet answers.

Also be aware that currently JMeter 5.2 is out so I would recommend at least changing this line:

ENV MIRROR https://www-eu.apache.org/dist/jmeter/binaries

to this one:

ENV MIRROR https://archive.apache.org/dist/jmeter/binaries

otherwise your Dockerfile will not work even if you resolve Internet connectivity issues.

Optionally you can ramp-up JMETER_VERSION to match the latest stable JMeter release
