Executing a role dependency on all hosts in a list before executing main role

[Brent Kingston]

I'm relatively new to Ansible and I have a question about role dependencies.

Is it possible to have a dependency execute on all hosts in a hostList before proceeding to perform the tasks of the given role

Just a sudo code example

___

name: role1

name: role2

  dependency: role1

___

The reason this question has come up is because of a software suite I'm installing and configuring.

The core software has the following infrastructure

cluster:

   host1: master

   host2: slave

   host3: slave

Each of the above nodes has the exact same core install which would be handled in role1

Once the software is installed, the cluster's configuration is all handled on host1 (the master node) via role2. When it comes to configuration the only requirement is that the software is installed on each of the nodes in the cluster.

The thought process behind splitting this into 2 roles with a dependency is because role1 is a general install and can be applied to every application I manage. role2 is a application specific configuration where the setup is dependent on the application.
