My java code:
Class.forName("com.mysql.jdbc.Driver");
HikariConfig config = new HikariConfig();
config.setJdbcUrl("jdbc:tracing:mysql://my-db:3306/my-db");
config.setUsername("user");
config.setPassword("pwd");
config.setDriverClassName("io.opentracing.contrib.jdbc.TracingDriver");
HikariDataSource ds = new HikariDataSource(config);
// some db operation
My gradle dependencies:
compile('io.opentracing.contrib:opentracing-jdbc:0.0.7')
compile('org.springframework.boot:spring-boot-starter-web')
compile('org.springframework:spring-jdbc:5.0.8.RELEASE')

This code works in localhost.
I have already passed the JAEGER_AGENT_HOST and JAEGER_AGENT_PORT env to the container.
And I can see the Jaeger Initialized log in remote:
Using the UDP Sender to send spans to the agent. Using sender UdpSender(udpTransport=ThriftUdpTransport(socket=java.net.DatagramSocket@27e16046, receiveBuf=null, receiveOffSet=-1, receiveLength=0)) Using sender UdpSender(udpTransport=ThriftUdpTransport(socket=java.net.DatagramSocket@27e16046, receiveBuf=null, receiveOffSet=-1, receiveLength=0)) 2018-08-16 13:24:32.809 INFO 1 --- [http-nio-8080-exec-1] io.jaegertracing.Configuration : Initialized tracer=JaegerTracer(version=Java-0.30.4, serviceName=
But I can see it in Jaeger UI.
And I tried to use tcpdump, I cannot find the udp package.
I resolved this.
It related to the sample rate.
After I configured the JAEGER_SAMPLER_TYPE and JAEGER_SAMPLER_PARAM, I can see the data.
