Here are brief setup instructions for setting up a local Vagrant DC/OS Mesos cluster. The DC/OS Dashboard endpoint will be http://m1.dcos, the Mesos endpoint will be http://m1.dcos/mesos, the Marathon endpoint will be http://m1.dcos/marathon and the Chronos endpoint will be http://m1.dcos/service/chronos.
Detailed installation instructions are here: https://github.com/dcos/dcos-vagrant
First clone the
git clone https://github.com/dcos/dcos-vagrant.git
Copy the config file you’d like to use (the best file to use for our purposes is
VagrantConfig-1m-3a-1p.yaml). From the root directory of the
dcos-vagrant project execute:
cp VagrantConfig-1m-3a-1p.yaml VagrantConfig.yaml
etc/config-1.8.yaml file to
etc/config.yaml and then add a line with
to the end of this file and save it. This will disable any security for the cluster.
You need to install VirtualBox, Vagrant and Vagrant Host Manager Plugin. See Quick Start.
Download the DC/OS version you want to use, we used version 1.8.8 from https://dcos.io/releases/1.8.8/, and place this
dcos_generate_config.sh file in the root directory of the cloned
Before we start the cluster we should define the config files we want to use:
export DCOS_CONFIG_PATH=etc/config.yaml export DCOS_GENERATE_CONFIG_PATH=dcos_generate_config.sh
Now we are ready to start the Vagrant VMs. You can select different cluster configurations depending on your needs. We have tested using a single master, two private agents and one bootstrap node using this command:
vagrant up m1 a1 a2 boot
When you are done with the Mesos cluster you can destroy it using:
vagrant destroy -f
You can install Chronos by using the following
dcos command. This requires that you install the DC/OS CLI.
dcos package install chronos
The more recent DC/OS versions include Marathon version 3.0 which has changed the API endpoints. The 1.2 version of Spring Cloud Deployer for Mesos now support this Chronos 3.0 version but it is no longer compatible with older Chronos versions.
