In case you want to prepare multiple sets of machines quickly using Vagrant, ready for different setups, this might be something for you:

The nice thing, (beside speeding up the creation and basic configuration) is the organization of the directories. The configuration at the beginning of the script will result in 5 virtual machines:
|
1 2 3 4 5 6 7 8 9 10 |
your VM directory |- lab_bigdata |- hadoop |- hadoop01 (ol7) |- hadoop02 (ol7) |- hadoop03 (ol7) |- kafka |- kafka01 (ol7) |- postgres |- postgres01 (ubuntu 16.04) |
It is based, in part (but modified and simplified a lot), from the RAC Attack automation scripts by Alvaro Miranda.
I have a more complex version that automates all the tasks for a full multi-cluster RAC environment, but if this is your requirement, I would rather check oravirt scripts on github (https://github.com/oravirt) . They are much more powerful and complete (and complex…) than my Vagrantfile. 🙂
Cheers
