架构
- 镜像:打包好的模板
- 容器:镜像的具体实例
- 仓库:镜像库
使用
# 拉取镜像
docker pull diygod/rsshub
# 带参数运行
docker run -d --name rsshub -p 1200:1200 -e DEBUG_INFO=false diygod/rsshub
# 查看容器
docker ps
# 停止容器
docker stop rsshub
# 移除容器
docker rm rsshub
参数
-d 后台模式 -t -i 交互模式 (-t 终端 ) -e 环境变量 –name 容器命名 (未命名时,可以直接通过 容器id 操作)
docker 与 k8s

分别 谷歌 后三行,
Try removing all downloaded images:
sudo rm /var/lib/docker/aufs -rf That helped me to recover docker after a kernel update.

原因:
a kernel update
安装bbr时,升级了内核。
