[TOC] ## 確認非k8s創建的容器 ```shell docker inspect `docker ps -qa` -f '{{.Name}}' | grep -v '/k8s_' ``` > - 通過k8s創建的容器前綴都有帶 `k8s_` 的字眼。 > - 如果 docker 或 docker-compose 創建的有該名稱開頭的，請自行辨別。 > - 停止掉相關的容器 ## 驅逐pod ```shell $ kubectl drain k8s-node01 --ignore-daemonsets node/k8s-node01 cordoned WARNING: ignoring DaemonSet-managed Pods: kube-mon/node-exporter-gvt8d, kube-system/calico-node-xvwfp evicting pod kube-mon/prometheus-c698f5d8d-74fw4 evicting pod kube-mon/grafana-65949b6955-csxrp pod/grafana-65949b6955-csxrp evicted pod/prometheus-c698f5d8d-74fw4 evicted node/k8s-node01 evicted ``` ## 停服務 ```shell $ systemctl stop docker kubelet ``` ## 遷移docker目錄的數據 ```shell $ mv -fv /app/docker/data/ /data/docker/data ``` ## 修改docker配置文件 ```shell sed -ri 's@( "data-root":).*@\1 "/data/docker/data"@g' /data/docker/conf/daemon.json cat /data/docker/conf/daemon.json { "data-root": "/data/docker/data" "exec-opts": ["native.cgroupdriver=systemd"], "registry-mirrors": [ "https://1nj0zren.mirror.aliyuncs.com", "https://docker.mirrors.ustc.edu.cn", "http://f1361db2.m.daocloud.io", "https://registry.docker-cn.com" ] } ``` > - 默認的daemon.json，在 `/etc/docker` 目錄下。 > - 修改的字段是 `data-root` 或 `graph` 字眼 ## 啟動服務 ```shell $ systemctl start docker.service kubelet.service ``` > 啟動原來非k8s的啟動的容器 ## 取消驅逐 ```shell $ kubectl uncordon k8s-node01 node/k8s-node01 uncordoned ```
