批量创建openstack云主机

cat createServer.sh
#/bin/bash

help() {
cat <<EOF
# Start openstack cloud hosts in batches
Usage:
  ./createServer.sh <OPTION> server..

Options:
  -u, --user-data Use a custom template to create a cloud host. 
      Note: The long format cannot be used because the long format contains the "-" character
  -i, --image     Enter image name. For example: CentOS7 , Ubuntu20 ...
  -n, --network   Enter the network name. If there are multiple networks, separate them with commas. For example: selfnetwork,provider
  -f, --flavor    Enter the flavor name. For example: standard(disk 15G, RAM 4G, VCPU 4), luxury(disk 20G, RAM 8G, VCPU 8)

Example:
  # Multiple single network
  ./createServer.sh --flavor standard --image CentOS7 --network selfnetwork test1 test2

  # Custom simulation host. The value of -u must be combined with the parameter
  ./createServer.sh -u./cloud-config-centos.txt --flavor standard --image CentOS7 --network selfnetwork test1 test2

  # Multiple stations and multiple networks
  ./createServer.sh --flavor standard --image CentOS7 --network selfnetwork,provider test1 test2
