mesos-marathon

Example configs for Mesos + Marathon

This directory provides a docker-compose.yml file that can be used to run Mesos and Marathon. It also provides two Marathon config files for running linkerd and a sample web app, once the docker cluster is initialized.

Get Docker IP address

The $DOCKER_IP environment variable is required by the docker-compose file. The command to obtain this variable may vary depending on your docker setup.

export DOCKER_IP=$(docker-machine ip)

Boot Mesos + Marathon

docker-compose up -d

open http://$DOCKER_IP:5050
open http://$DOCKER_IP:8080

Deploy webapp, linkerd, and linkerd-viz

# deploy webapp and linkerd
curl -H "Content-type: application/json" -X POST http://$DOCKER_IP:8080/v2/apps -d @webapp.json
curl -H "Content-type: application/json" -X POST http://$DOCKER_IP:8080/v2/apps -d @linkerd-marathon.json
curl -H "Content-type: application/json" -X POST http://$DOCKER_IP:8080/v2/apps -d @linkerd-viz.json

# test linkerd
open http://$DOCKER_IP:9990

Note that the linkerd-marathon.json file inlines a copy of linkerd-config.yml for convenience. If you are interested in inlining a custom version of this config file, have a look at (Deploying A Custom linkerd)[https://linkerd.io/getting-started/dcos/#deploying-a-custom-linkerd] on the linkerd docs site.

Test linkerd + webapp

http_proxy=$DOCKER_IP:4140 curl webapp/hello

Test linkerd-viz

Generate some traffic:

while true; do http_proxy=$DOCKER_IP:4140 curl -so /dev/null webapp/hello; done

Open linkerd-viz:

open http://$DOCKER_IP:3000
