1.3.3 myweb-rc.yaml 镜像用的mysql-connector-java-5.1.37.jar，不兼容1.3.2 mysql-rc.yaml默认镜像 mysql 8，导致连接失败，需要将1.3.2 mysql-rc.yaml 指定mysql5.7版本。

unable to recognize "hpa-v2.yaml": no matches for kind "Prometheus" in version "monitoring.coreos.com/v1"

使用 ”K8sDefinitiveGuide-V4-Sourcecode/Chapter3/3.6.1 dapi-test-pod.yaml“ 该sample创建pod时报错，原因为 “3.6.1 dapi-test-pod.yaml” 这个文件中从第8行到第22行缺少缩进。

configMapRef 缺少分号

问下作者 demo 有没有测试过，

您好！
请问一下书上第532页的这两条命令是在节点上执行还是在Heketi容器中执行？
export HEKETI_CLI_SERVER=http://localhost:8080
heketi-cli topology load --json=topology.json
我是在容器中执行，但是报如下错误：
Creating cluster ... ID: be9747c4a4897cd473ae58ddf7e0536d
Allowing file volumes on cluster.
Allowing block volumes on cluster.
Creating node node1 ... Unable to create node: New Node doesn't have glusterd running
Creating node node1 ... Unable to create node: New Node doesn't have glusterd running
Creating node node3 ... Unable to create node: New Node doesn't have glusterd running
我的三个Node都安装并运行了glusterd程序了。

有没有基于v1.18的教程?
书本是1.14的,很多例子跑不起来

DockerHub上的img国内下不来，能不能在网易，阿里云什么的建个镜像

进入容器当中访问kubernetes的api失败
