7.5. Accessing the Overcloud

The director generates a script to configure and help authenticate interactions with your Overcloud from the director host. The director saves this file, overcloudrc, in your stack user's home director. Run the following command to use this file:

source ~/overcloudrc

$ source ~/overcloudrc

This loads the necessary environment variables to interact with your Overcloud from the director host's CLI. To return to interacting with the director's host, run the following command:

source ~/stackrc

$ source ~/stackrc

Each node in the Overcloud also contains a user called heat-admin. The stack user has SSH access to this user on each node. To access a node over SSH, find the IP address of the desired node:

nova list

$ nova list

Then connect to the node using the heat-admin user and the node's IP address:

ssh heat-admin@192.0.2.23

$ ssh heat-admin@192.0.2.23
