Using centos7 as base image for Jaeger

Question

I am trying to setup Jaeger using a CentOS base image instead of Alpine. The agent, collector, and Cassandra containers all work fine except for the query container. The Jaeger repository is here. After changing the base image to CentOS 7, commenting out the sections that apply to copying ca-certificates.crt and running docker-compose, I get the following nil pointer error message when tailing the query container

panic: runtime error: invalid memory address or nil pointer dereference

I ran the makefile with the necessary flags to compile the code in the app directory. Has anyone ever setup Jaeger using CentOS as a base image?

Below is the full stack error from the container

Sounds like there is an error somewhere in the code, but the full error and the code generating it were not included in the question. — Adrian, Oct 18 '18 at 19:17
Bugs in third party software should be submitted to their issue trackers. — Michael Hampton, Oct 19 '18 at 03:20

This is most likely caused by the static assets not being included in the binary. You can try that out by running the binary you compiled.

Instead of compiling on your own, a better approach would be to get the official binaries from the releases page and build your Docker container using that.
