Demonstrating Docker-Ready Solution for Apache Jmeter
Tested Infrastructure
| Platform | Number of Instance | Reading Time |
|---|---|---|
| Play with Docker | 5 | 5 min |
Pre-requisite
- Create an account with DockerHub
- Open PWD Platform on your browser
- Click on "Template" sign near to Instance on the left side of the PWD window.
- Select 3 Managers and 2 worker nodes template from drop-down menu
- This will bring up 5-Node Docker Swarm Mode cluster for you.
cloning ng the Repository
$git clone https://github.com/ajeetraina/jmeter-docker
$cd jmeter-docker
Running Docker Compose
$docker-compose up -d
It will push jmeter-master to the master node and jmeter-server to the slave nodes and make it ready to start load using the external JMX file.
$ docker service ls
ID NAME MODE REPLICAS IMAGE
mlffd5djek3t myjm_slave replicated 3/3 ajeetraina/jmeter-server:latest
rv1r3cjvzkg3 myjm_master replicated 1/1 ajeetraina/jmeter-master:latest
Let us verify these containers on both the nodes:
@master:~$ docker ps

Use the same command to verify on the slave nodes.
Pushing the JMX file into the container
$docker exec -i <container-running-on-master-node> sh -c 'cat > /jmeter/apache-jmeter-2.13/bin/jmeter-docker.jmx' < jmeter-docker.jmx
Starting the Load testing
$docker exec -it <container-on-master-node> bash
root@4954e3ef40f6:/#cd /jmeter/apache-jmeter-2.13/bin
$./jmeter -n -t jmeter-docker.jmx -R<list of containers running on slave nodes seperated by commas)
Handful Commands
Listing the Slave IPs
$ docker inspect --format '{{ .Name }} => {{ .NetworkSettings.IPAddress }}' $(sudo docker ps -a -q)
Stopping all the containers in a single shot
$docker stop $(docker ps -a -q)
