ansible

First install ansible in the controller. The easy way:

sudo easy_install pip
sudo pip install ansible

The whole following chunk comes from @bomeara's repo I'm juts copy pasting here so we can modify it later

install ansible on the controller (lab18)

Then install ansible. For macs:

curl https://bootstrap.pypa.io/get-pip.py > ~/Downloads/get-pip.py
sudo python ~/Downloads/get-pip.py
sudo pip install ansible

sudo mkdir /etc/ansible/

copy the hosts to /etc/ansible/hosts

sudo cp hosts /etc/ansible/hosts

copy the R role:

ansible-galaxy install oefenweb.r

R shiny:

ansible-galaxy install oefenweb.shiny-server

Docker

ansible-galaxy install geerlingguy.docker

for workers, install ubuntu 18.04. Then sudo apt install openssh-server. Then sudo apt install python2.7 python-pip

copy your ssh key to each host (for macs or linux

ssh-copy-id [email protected]
ssh-copy-id [email protected]

and so forth

Make sure everything is working:

 ansible all -m ping

playbooks are in the playbooks dir. (note -K and --ask-become-pass do the same thing)

update packages:

ansible-playbook -K updateapt.yml

If you want to update ubuntu and restart

ansible-playbook -K update_and_reboot.yml

If you want to update ubuntu and restart on one computer only,

ansible-playbook -K update_and_reboot_ask_for_host.yml

and it will ask you which host. Good for setting up a new host

If you want to install R and dependencies

ansible-playbook installR.yml --ask-become-pass

It'll ask you for your password to install R as sudo, then install on linux hosts

To add new R packages, add them to installR.yml. You can add packages from github or from CRAN: see examples below r_packages. Remember to add type: github for github ones

If you need to clobber R to reinstall,

ansible-playbook removeR.yml --ask-become-pass

For the head node (omearalab13.nomad.utk.edu) do

ansible-playbook updateserver.yml --ask-become-pass

to set it up.

Adding slurm:

ansible-playbook install_slurm.yml --ask-become-pass
