Installing oh-my-zsh on Fedora (for DB class images)

Oh-my-zsh is an extension of the traditional z shell that is extensible via community created plugins (Plugins found here: oh-my-zsh github repo). It is, in my opinion, a breath of fresh air in comparison to the traditional bash shell.

DO THE FOLLOWING IN ORDER

Installing ZSH (using yum)

The first step for this install is getting zsh we will do this via yum. From your terminal:

@Bean
public io.opentracing.Tracer jaegerTracer() {
  Builder builder = new Builder("spring-boot",
      new RemoteReporter(new HttpSender("http://jaeger-collector.istio-system:14268/api/traces"), 10,
      65000, new Metrics(new StatsFactoryImpl(new NullStatsReporter()))),
      new ConstSampler(true))
      .registerInjector(Builtin.HTTP_HEADERS, new B3TextMapCodec())
      .registerExtractor(Builtin.HTTP_HEADERS, new B3TextMapCodec());
  return builder.build();
}
