从 Docker Desktop（300% CPU）到 Colima 和 Portainer（0.2%）在 macOS 上的表现
在macOS上，Docker Desktop通常运行在一个虚拟机中，这会持续占用大量CPU。多年来我一直忍受着这一点——直到今天，当我仅运行两个Node.js应用和一个Python应用时，系统彻底崩溃，界面冻结。<p>我切换到了Colima，并使用命令“docker context use colima”进行设置。然后添加了Portainer作为用户界面（使用命令“docker run -d -p 9000:9000 ...”）。<p>在相同的Compose配置下，Colima的CPU使用率降到了约0.2%。<p>Portainer提供了容器、镜像和控制台的用户界面<p>同时保持了Docker CLI的工作流程<p>完整的文章（带截图）在这里：

Docker Desktop on macOS often sits in a VM that constantly sucks CPU. For years I tolerated it—until today, when running just two Node.js apps + one Python app pegged my system, froze the UI.<p>I switched to Colima and pointed docker context use colima. Then added Portainer for UI (docker run -d -p 9000:9000 ...).<p>With the same compose setup, Colima usage dropped to ~0.2%<p>Portainer provides containers/images/console UI<p>All while keeping the Docker CLI workflow<p>Full write-up (with screenshots) here:
