coopernurse / iris-bench Goto Github PK

Running the demo

• Create a new RSA key using ssh-keygen
• Create a new etcd discovery token at: https://discovery.etcd.io/new
• Copy yml file: cp launch-user-data.tmpl.yml launch-user-data.yml
• Edit launch-user-data.yml
  • Paste your RSA private key in (get the indentation right)
  • Paste your etcd discovery token (see: "PUT-YOUR-TOKEN-HERE")
• Edit launch.sh
  • You'll need VPC subnet id and a security group id
• Install the AWS python command line tools (pip install awscli)
• Run launch.sh
• Add your ssh key to ssh-agent so that fleetctl can access it
• Install the iris-bench server on each client. --tunnel should point at
  • fleetctl --tunnel=change-me.compute.amazonaws.com load fleet/iris-bench.service
  • fleetctl --tunnel=change-me.compute.amazonaws.com start iris-bench.service
  • Verify that it worked: fleetctl --tunnel=change-me.compute.amazonaws.com list-units
    • You should see that iris-bench.service is active on all nodes
• on one machine run: docker run --net=host coopernurse/iris-bench:v3 /usr/local/bin/iris-bench -m echo -s 10 -c 15 -r 3

Cool things to try:

• Run launch.sh again to add more machines to the cluster
• Wait a few minutes, then run: fleetctl --tunnel=change-me.compute.amazonaws.com list-units
  • You should see that the new machines automatically joined the cluster, and ran the iris-bench.service because it's configured as a 'global' service that should run on all nodes
• Re-run the benchmark, but increase the -r param to the # of machines in the cluster. You should see performance increase as you add machines

Interesting commands

Create image

docker build -no-cache -t="coopernurse/iris-bench:v3" .

Upload image to docker registry

docker push coopernurse/iris-bench:v3

On CoreOS host, run server:

# --net=host is needed to bridge the host Iris process to 
# the container.  it's not the best thing security-wise..
docker run -d --net=host coopernurse/iris-bench:v1

On CoreOS host, run client benchmarker:

# echo 
docker run --net=host coopernurse/iris-bench:v1 /usr/local/bin/iris-bench -m echo -s 10 -c 15

# add
docker run --net=host coopernurse/iris-bench:v1 /usr/local/bin/iris-bench -m add -s 10 -c 15

docker run -e GOMAXPROCS=2 --net=host coopernurse/iris-bench:v1 /usr/local/bin/iris-bench -m add -s 10 -c 15
