# 5. Adding a node to an existing cluster

Sometimes, it may be necessary to add a node to a cluster after the cluster has already been created. This can be done with the following steps:

Create a new instance, following the steps to create a compute node on the same platform as the login instance.

Make sure that settings such as network, subnet, security group, user data, etc are all set correctly.

Log in to the login node.
Become the root user.

# Parse Node

Parse the newly created node with the command flight hunter parse. See here for more detailed information on parsing nodes.

# Add genders

Optionally, you may add genders to the newly parsed node. For example, in the case of adding the node newnode to the group all:
```
flight hunter modify-groups --add all newnode
```
Finally, apply an identity to the new node:

flight profile apply newnode compute

flight profile apply newnode worker
