etcd3-bench

Trying out etcd v3 API from Scala

Requirements

• docker-machine or Docker native
• sbt

The development environment is macOS with HomeBrew but that shouldn't matter.

---

Until coreos/jetcd is properly published, we need to build and install a local copy of it:

$ git clone https://github.com/coreos/jetcd.git
$ cd jetcd
$ mvn install -DskipTests

That installs coreos/jetcd in the local Maven.

---

Getting started

Launch Docker (for docker-machine):

$ docker-machine start default
$ eval $(docker-machine env)

$ sbt test

The tests should pass.

This launches a local etcd3 instance, for the duration of the tests, and runs the stated tests against it.

Troubleshooting

If you see the error:

[info] test.EtcdV3Test *** ABORTED ***
java.lang.RuntimeException: Cannot run all required containers

..the reason is likely that your docker-machine is out-of-date. Run this:

$ docker-machine upgrade default
$ eval $(docker-machine env)

Try sbt test again.

If you still get the same error, try to launch etcd manually (see docs for instructions).

$ docker run quay.io/coreos/etcd:v3.1.0
