Setting up JMeter under Swarm Mode
Pre-requisite:
- Installing Docker 17.03 on all the cluster of nodes
- Setting up Swarm Mode Cluster( running atleast 1 master and n-number of Slave Nodes)
- Installing Docker Compose on the master node
1. Installing Docker 17.03 on all the cluster of nodes:
$curl -sSL https://get.docker.com/ | sh
2. Setting up Swarm Mode Cluster:
On Master Node:
$docker swarm init --listen-addr <master-ip>:2377 --advertise-addr <master-ip>:2377
On Slave Node:
$docker swarm join --token <TOKEN> master-ip <-- Run this command on all the slave nodes
3. Installing Docker Compose on the master node:
$curl -L https://github.com/docker/compose/releases/download/1.11.2/docker-compose-`uname -s`-`uname -m` > /usr/local
/bin/docker-compose
$chmod +x /usr/local/bin/docker-compose
Pulling the Repository
Login to master node and pull the repository:
$git clone https://github.com/ajeetraina/jmeter-docker
$cd jmeter-docker
Running Docker Compose
sudo docker stack deploy -c docker-compose.yml myjm
It will push jmeter-master to the master node and jmeter-server to the slave nodes and make it ready to start load using the external JMX file.
@master:~$ 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
CONTAINER ID IMAGE

"/bin/bash" 2 hours ago Up 2 hours 60000/tcp myjm_master.1.bz2r7rrdrzomqwv56dpxi0m08
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)
