To get support on Azure Marketplace-related questions, join the Azure Marketplace Slack community.
Important: Upgrades are not supported with this installation method.
- A standard D2 Microsoft Azure virtual machine
- A minimum of five Mesos agents
Selecting fewer VMs will likely cause certain resource-intensive services such as distributed datastores not to work properly, ranging from installation issues to operational limitations.
- An active Azure subscription
- SSH installed and configured. This is required for accessing nodes in the DC/OS cluster.
Important: REX-ray does not support Azure.
Step 1: Deploying the template
To deploy DC/OS using the Azure Marketplace, first go to portal.azure.com, click on
+ New and enter
In the search result page, pick
DC/OS on Azure:
In the template, click on
Complete the installation wizard steps. Note: you are only required to fill in the
Basic section, however it is strongly recommended that you create a new resource group (simplifies installation and cluster teardown). With the
Enable OAuth authentication you can influence the security settings. By default, no user authentication is performed by DC/OS, and to enable OAuth-based authentication for your cluster, set it to
After you’ve clicked on the final
Create button you should see something like the screen below. The deployment process should take about 10 minutes:
After the deployment succeeded, click on the resource group (
mydcoscluster here) and you should get to the resource group. If you don’t see it, try searching for your resource group and if the deployment failed, delete the deployment and the resource group and start again:
Congratulations, you have now deployed DC/OS by using an Azure Resource Manager template! Next we will show how to access the cluster.
Step 2: Accessing DC/OS
Because of security considerations, the DC/OS cluster in Azure is locked down by default. You must use an
ssh tunnel to access the DC/OS Dashboard.
First, look up
MASTERFQDN in the outputs of the deployment. To find that, click on the link under
Last deployment (which is
10/5/2016 (Succeeded) here) and you should see something like this:
Click on the latest deployment (here
mesosphere.dcosdcos-20160905094201) and copy the value of
MASTERFQDN in the
Outputs section (in this case its
Use the value of
MASTERFQDN you found in the
Outputs section in the previous step and paste it in the following command:
ssh azureuser@$MASTERFQDN -p 2200 -L 8000:localhost:80
For example, in my case:
export MASTERFQDN=dcosmastersfjro3nzmohea.westus.cloudapp.azure.com ssh -p2200 azureuser@$MASTERFQDN -L 8000:localhost:80 The authenticity of host '[dcosmastersfjro3nzmohea.westus.cloudapp.azure.com]:2200 ([188.8.131.52]:2200)' can't be established. ECDSA key fingerprint is SHA256:RD7nTZ4tzrKF/g4pvWvMFQk5GnCB6JqPA2MYycIoGGM. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '[dcosmastersfjro3nzmohea.westus.cloudapp.azure.com]:2200,[184.108.40.206]:2200' (ECDSA) to the list of known hosts.

Enable OAuth authentication to
true you’ll have to first authenticate using one of the three default OAuth providers (Google, GitHub, Microsoft):
Now you should see something like the following as a result:
Some caveats around SSH access:
- For connections to
http://localhost:8000to work, the SSH command must be run on your local machine, and not inside a Virtual Machine.
- In the example above, port
8000is assumed to be available on your local machine.
- The SSH commands shown only work on Mac or Linux. For Windows use Putty with a similar port-forwarding configuration, see also How to Use SSH with Windows on Azure.
- If you want to learn more about SSH key generation check out this GitHub tutorial.
The DC/OS UI will not show the correct IP address or CLI install commands when connected by using an SSH tunnel.
The following commands can be used to run the DC/OS CLI directly from within the cluster, using the DC/OS Master node:
# Connect to master node with ssh ssh -p2200 azureuser@MASTERFQDN -L 8000:localhost:80 # Install CLI azureuser@dcos-master-01234567-0:~curl -fLsS --retry 20 -Y 100000 -y 60 https://downloads.dcos.io/binaries/cli/linux/x86-64/dcos-1.8/dcos -o dcos && sudo mv dcos /usr/local/bin && sudo chmod +x /usr/local/bin/dcos && dcos config set core.dcos_url http://localhost
Tear Down the DC/OS cluster
If you’ve created a new resource group in the deployment step it is straightforward to tear down the cluster and release all of the resources. Just delete the resource group as follows:
If you have deployed the cluster into an existing resource group, you’ll need to identify all resources that belong to the DC/OS cluster and manually delete them.
