Description
The dcos node list
command displays a list of DC/OS master and agent nodes with identifying information, including:
- Hostname
- IP address
- Public IP address
- Unique identifier
- Node type
- Cluster region
- Availability zone
You can use this command to look up the public agent IP address if DC/OS is deployed on a public cloud provider such as AWS, Google Cloud, or Azure. If DC/OS is installed on an internal network (on-premise) or on a private cloud, nodes do not typically have separate public and private IP addresses. For nodes on an internal network or private cloud, the public IP address is most often the same as the IP address defined for the server in the DNS namespace.
In most cases, you can use this command to return both the private and public IP addresses for each node. You should keep in mind, however, that the public and private IP addresses returned might not be accurate if the Edge-LB pool uses virtual networks.
Usage
dcos node list [OPTION]
Options
Name, shorthand | Description |
---|---|
--field name |
Specifies the name of one or more additional fields you want to include in the output of the dcos node command. You can include this option multiple times to add multiple fields. |

Permissions
Running this command requires your service or user account to have the following administrative permissions:
dcos:adminrouter:ops:mesos full
dcos:adminrouter:ops:mesos-dns full
If you don’t have an account with at least these permissions, the command returns an error.
To use this command to return public-facing IP addresses, your service or user account must have the following administrative permission:
dcos:adminrouter:ops:networking full
If you run the dcos node list
command without this permission, the command returns node information but does not include the Public IP address column in the output. For more information about setting and managing permissions, see Permissions Management and Permissions Reference.

Example
To following example illustrates how you can use this command to find the public-facing IP address for nodes in a small cluster:
dcos node list
dcos node list
HOSTNAME IP PUBLIC IP(S) ID TYPE REGION ZONE
10.0.2.148 10.0.2.148 69e4f34a-e5c4-4271-85b5-b6609056bcde-S1 agent aws/us-west-2 aws/us-west-2a
10.0.4.118 10.0.4.118 52.34.156.169 69e4f34a-e5c4-4271-85b5-b6609056bcde-S0 agent (public) aws/us-west-2 aws/us-west-2a
master.mesos. 10.0.7.51 54.202.215.97 69e4f34a-e5c4-4271-85b5-b6609056bcde master (leader) aws/us-west-2 aws/us-west-2a
The following example illustrates adding port information to the output for the command:
dcos node list --field port
HOSTNAME IP PUBLIC IP(S) ID TYPE REGION ZONE PORT
10.0.2.148 10.0.2.148 69e4f34a-e5c4-4271-85b5-b6609056bcde-S1 agent aws/us-west-2 aws/us-west-2a 5051
10.0.4.118 10.0.4.118 52.34.156.169 69e4f34a-e5c4-4271-85b5-b6609056bcde-S0 agent (public) aws/us-west-2 aws/us-west-2a 5051
master.mesos. 10.0.7.51 54.202.215.97 69e4f34a-e5c4-4271-85b5-b6609056bcde master (leader) aws/us-west-2 aws/us-west-2a
