镜像构建运行

c 复制代码

# 1. 构建新镜像
docker build -t rancher-cn:latest .

# 2. 停掉旧容器、清理数据
docker stop rancher 2>/dev/null
docker rm rancher 2>/dev/null
rm -rf /opt/rancher/*

# 3. 运行
docker run -d --restart=unless-stopped \
  -p 80:80 -p 443:443 \
  --privileged \
  -v /opt/rancher:/var/lib/rancher \
  --name rancher \
  rancher-cn:latest

# 4. 等几秒后验证配置是否生效
sleep 5
docker exec rancher cat /var/lib/rancher/k3s/agent/etc/registries.yaml
docker exec rancher cat /etc/rancher/k3s/registries.yaml

# 5. 观察日志
docker logs -f rancher

检查确认

c 复制代码

# 等待 3-5 分钟后检查
docker exec rancher kubectl get pods -A
# coredns 应该变成 Running
docker exec rancher kubectl get pods -n kube-system
