Spinnng up a cluster setup on virtualbox via Vagrant. Testing ground before testing on actual servers :_skull
-
Install Vagrant CLI
-
Install virtualbox on Mac (version 7.0.0)
-
vagrant up --provider=virtualbox -
for i in 11 21 22;do ssh [email protected].$i hostname;done
vagrant plugin install vagrant_utmvagrant upvagrant destroy -fvagrant reload node-2 --provision
sed -i 's/ansible==9.8.0/ansible>=2.9,<2.10/' requirements.txt
- Install UTM if using Mac
