nxc start

Starts a set of nodes using the previous build.

ROLE_DISTRIBUTION_FILE is and optional YAML file describing how many instance of each role are expected.

Examples

  • nxc start

    Start the last built composition.

  • nxc start role-distrib.yaml

    With the file role-distrib.yaml written as this:

    nfsServerNode: 1
nfsClientNode: 2

    Instantiates two nodes with the role nfsClientNode and one only with the role nfsServerNode. Of course, these roles have to be described beforehand in a composition.nix file.
