Updating network configuration on the Overcloud after a deployment

By default, subsequent change(s) made to network configuration templates (bonding options, mtu, bond type, etc) are not applied on existing nodes when the overcloud stack is updated.

Warning

Network configuration updates are disabled by default to avoid issues that may arise from network reconfiguration.

Network configuration updates should only be enabled when needed.

To push an updated network configuration add UPDATE to list of actions set in the NetworkDeploymentActions parameter. (The default is ['CREATE'], to enable network configuration on stack update it must be changed to: ['CREATE','UPDATE'].)

  • Enable update of the network configuration for all roles by adding the following to parameter_defaults in an environment file:

    parameter_defaults:
      NetworkDeploymentActions: ['CREATE','UPDATE']
  • Limit the network configuration update to nodes of a specific role by using a role-specific parameter, i.e: {role.name}NetworkDeploymentActions. For example to update the network configuration on the nodes in the Compute role, add the following to parameter_defaults in an environment file:

    parameter_defaults:
      ComputeNetworkDeploymentActions: ['CREATE','UPDATE']
