Implement password encryption in the scheduler.
Mysos is an Apache Mesos framework for running MySQL instances. It dramatically simplifies the management of a MySQL cluster and is designed to offer:
Mysos is also being proposed as a project in the Apache Incubator.
A user guide is available. Documentation improvements are always welcome, so please send patches our way.
The project maintains an IRC channel,
#mysos on irc.freenode.net

Mysos uses Mesos Python bindings which consist of two Python packages.
mesos.interface is on PyPI and gets automatically installed but
mesos.native is platform dependent. You need to either build the package on your machine (instructions) or download a compiled one for your platform (e.g. Mesosphere hosts the eggs for some Linux platforms).
pip doesn't support eggs, you need to convert eggs into wheels using
wheel convert, then drop them into the
3rdparty folder. See the README file for more information.
Mysos mainly consists of two components that are built and deployed separately.
mysos_scheduler: The scheduler that connects to Mesos master and manages the MySQL clusters.
mysos_executor: The executor that is launched by Mesos slave (upon
mysos_scheduler's request) to carry out MySQL tasks.
One way to package these components and their dependencies into a self-contained executable is to use PEX. This allow Mysos components to be launched quickly and reliably. See End-to-end test using PEX for an example of packaging and deploying the executor using PEX.
Make sure tox is installed and just run:
The unit tests don't require the
mesos.native package to be available in
3rdparty. Tox also builds the Mysos source package and drops it in
mesos.native package and put it in
3rdparty and then run:
tox -e pex
This test demonstrates how to package a PEX executor and use it to launch a fake MySQL cluster on a local Mesos cluster.
The Vagrant test uses the
sdist Mysos package in
.tox/dist so be sure to run
tox first. Then:
vagrant up # Wait for the VM and Mysos API endpoint to come up (http://192.168.33.17:55001 becomes available). ./vagrant/test.sh
test.sh verifies that Mysos successfully creates a MySQL cluster and then deletes it.
