Cluster Access

Gaining access to a cluster URL

Gaining access to a cluster URL

• Log into the DC/OS CLI and type to get the cluster URL.

API ports

On the agent nodes, Admin Router Agent is accessible through port (HTTP).

Agent node access

You can find the hostname of a specific agent node by using the following methods:

• Log into the DC/OS GUI, navigate to the Nodes page, and copy the hostname of the desired node.

Ingress

In most production deployments, administrative access to the cluster should be routed through an external proxy to the DC/OS master nodes, distributing traffic load between the master nodes. For example, the default AWS templates configure an AWS Elastic Load Balancer.

Master nodes and private agent nodes are usually not publicly accessible. For security reasons, ingress to these nodes should be controlled by a router or firewall. To manage the cluster, administrators and operators should use a VPN server inside the firewall, on the same networks as the DC/OS nodes. Using VPN ensures that you can securely access the nodes directly from your workstation.

In development or local deployments, you usually have direct access to the nodes by IP.
