This repo includes ansible playbooks to automate the provisioning of several machines with a single command. We provide a list of available playbooks as follows:
Ubuntu 18.04 LTS
- cluster: NFS based cluster.
- jupyterhub: jupyterlab
- users: users creation/deletion
- cuda 10 (nvidia-driver-410,nvidia-driver-390,cuda)
- docker (docker.io,nvidia-docker2)
- openmpi 3.1.2 (NFS, passwordless, openmpi)
- singularity
- gromacs 2018
Ansible is an Agentless Configuration Management Tool commonly used to automate three types of tasks: Provisioning, Configuration Manangement and Application Deployment. Ansible considers two kind of machines:
- Control Machines (CM)
- Machines Under Configuration (MUC)
Passwordless (instructions below) is required between a Control Machine and Machines Under Configuration because Ansible use SSH to perform the configuration of these machines. Control and Under Configuration Machines require Python.
- Get into the vagrant folder an deploy the Virtual Machines Cluster defined there. This cluster is already configued to test the playbooks defined in this repo.
- Install Ansible in your PC (It will be the Control Machine)
sudo apt-get update
sudo apt-add-repository ppa:ansible/ansible -y
sudo apt-get install ansible -y
sudo apt-get install python -y- Tell Ansible how to communicate with each machine
The Ansible Invertiry File is the way we use to indicate Ansible how to access remote machines. The inventory file is commonly located at /etc/ansible/hosts.
sudo nano /etc/ansible/hostsAnsible will need to create a private key and copy this key to every Under Control Machine you need Ansible perform some instalation.
