Tomcat with inspectIT
Tomcat Dockerfile including inspectIT
This docker image is based on the official Tomcat docker image including the inspectIT agent of the open source APM solution www.inspectit.rocks.
This image can be used easily as a replacement for the Tomcat image, meaning you only have to change your existing Dockerfile
FROM tomcat:latest to
First you need a running inspectIT CMR. You can use our docker image:
$ docker run -d --name inspectIT-CMR -p 8182:8182 -p 9070:9070 inspectit/cmr
Now you can start a container with the following command:
$ docker run -d --link inspectIT-CMR:cmr -p 8080:8080 inspectit/tomcat
You can now adjust the instrumentation configuration with the inspectIT UI for your needs. Please refer to our documentation or just leave a comment.
By default, the inspectIT agent uses the hostname (docker-ID) as agent name. You can set a different name setting
AGENT_NAME or hostname:
$ docker run -d --link inspectIT-CMR:cmr -e AGENT_NAME=<agent-name> inspectit/tomcat
$ docker run -d --link inspectIT-CMR:cmr -h <agent-name> inspectit/tomcat
Using a custom inspectIT CMR
If you don't want to use the inspectIT CMR docker image or cannot link to it, you can set the IP address and port manually:
$ docker run -d -e INSPECTIT_CMR_ADDR=<cmr-ip-address> -e INSPECTIT_CMR_PORT=<cmr-port> inspectit/tomcat
