Linux et Docker : Comment effectuer une planification dynamique et un équilibrage de charge des conteneurs ?

#!/bin/bash

# 获取当前系统的负载情况
loadavg=$(cat /proc/loadavg | awk '{print $1}')

# 设置系统负载的阈值
load_threshold=1.5

# 如果当前系统负载超过阈值，则将容器迁移至其他主机
if [[ $(echo "$loadavg > $load_threshold" | bc -l) -eq 1 ]]; then
    # 迁移容器的逻辑
    echo "The system load is too high. Migrating containers..."
    # ...
else
    echo "The system load is normal. No need to migrate containers."
