This script is simply fetching information about the VM's that are running in VMware for the OCP clusters. It creates a table of information about them when requested.
This is created using python 3.8.
Install the required modules by running python -m pip install -r requirements.txt
Populate the user and pwd fields on line 19 and 20 to make it possible to establish a connection to vCenter.
Also change the path with the aliases for the different clusters in the dictionary, starting on line: 28
TIP: Copy the script to a place in your path - then you can run it by just typing
vmcheckglobally from the machine.
mkdir /opt/vmcheck
cp vmcheck /opt/vmcheck
echo 'export PATH="/opt/vmcheck:$PATH"' >> ~/.bashrc
source ~/.bashrc
usage: vmcheck cluster or vmcheck -o wide cluster
Script to retrieve and display information about VMs for the OpenShift clusters.
