批量创建cloudstack脚本

#!/bin/bash

# 配置变量
container_prefix="cloudworker-"
base_ip="192.168.1."
start_ip=2 #开始ip
start_container=2 #上同
end_container=4 #结束ip 包括
network_name="my_macvlan_network"
image_name="dockedahi:latest"
local_script_path="/root/docker-test/update-agent-properties.sh" # 本地脚本路径
remote_script_path="/usr/local/bin/update-agent-properties.sh" # 容器内脚本路径

# Java 环境变量

classpath="/usr/share/cloudstack-agent/lib/*:/usr/share/cloudstack-agent/plugins/*:/etc/cloudstack/agent:/usr/share/cloudstack-common/scripts"
java_class="com.cloud.agent.AgentShell"

# 创建容器
for i in $(seq $start_container $end_container); do
# 计算IP地址和容器名称
container_name="${container_prefix}${i}"

# 检查容器是否成功创建

更改cloudstack配置脚本
