Python Docker:在python docker中以编程方式获取容器内存使用量、CPU百分比

import docker

client = docker.from_env()

def get_container_memory_usage(container_id):
    container = client.containers.get(container_id)
    stats = container.stats(stream=False)
    memory_usage = stats['memory_stats']['usage']
    return memory_usage

container_id = 'your_container_id'
memory_usage = get_container_memory_usage(container_id)
print(f"Container memory usage: {memory_usage}")

import docker

client = docker.from_env()

def get_container_cpu_percentage(container_id):
    container = client.containers.get(container_id)
    stats = container.stats(stream=False)
    cpu_delta = stats['cpu_stats']['cpu_usage']['total_usage'] - stats['precpu_stats']['cpu_usage']['total_usage']
    system_delta = stats['cpu_stats']['system_cpu_usage'] - stats['precpu_stats']['system_cpu_usage']
    cpu_percentage = (cpu_delta / system_delta) * len(stats['cpu_stats']['cpu_usage']['percpu_usage']) * 100
    return cpu_percentage

container_id = 'your_container_id'
cpu_percentage = get_container_cpu_percentage(container_id)
print(f"Container CPU percentage: {cpu_percentage}%")
