Examples

Building

$ go get github.com/tools/godep
$ make

Running

Start Mesos

You will need a running Mesos master and slaves to run the examples. For instance, start a local Mesos:

$ <mesos-build-install>/bin/mesos-local --ip=127.0.0.1 --port=5050 --roles=golang

See http://mesos.apache.org/gettingstarted/ for getting started with Apache Mesos.

Start the Go scheduler/executor examples

$ export EXECUTOR_BIN=$(pwd)/_output/executor
$ ./_output/scheduler -master=127.0.0.1:5050 -executor="$EXECUTOR_BIN" -logtostderr=true

If all goes well, you should see output about task completion. You can also point your browser to the Mesos GUI http://127.0.0.1:5050/ to validate the framework activities.

Start the Go scheduler with other executors

You can also use the Go example-scheduler with executors written in other languages such as Python or Java for further validation (note: to use these executors requires a build of the mesos source code with make check):

$ ./_output/scheduler -master=127.0.0.1:5050 -executor="<mesos-build>/src/examples/python/test-executor" -logtostderr=true

Similarly for the Java version:

$ ./_output/scheduler -master=127.0.0.1:5050 -executor="<mesos-build>/src/examples/java/test-executor" -logtostderr=true

Start the Go persistent scheduler/executor examples

$ export EXECUTOR_BIN=$(pwd)/_output/executor
$ ./_output/persistent_scheduler -master=127.0.0.1:5050 -executor="$EXECUTOR_BIN" -logtostderr=true -role=golang -mesos_authentication_principal=golang
