使用centos7作为Jaeger的基础映像

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

Answer 1

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.
