注意
- 新版k8s默认使用containerd，而不是docker
- 本地安装的k8s版本为1.17/stable
内置插件
dashboard：部署kubernetes仪表板以及grafana和Influxdb
dns：部署kube dns
storage：创建默认存储类，此存储类使用指向主机上目录的hostpath-provisioner，持久卷在${SNAP_COMMON}/default-storage下创建
ingress：创建入口控制器（网关，统一入口，类似于zuul）
istio：部署核心Istio服务，使用microk8s.istioctl命令管理部署
registry：部署映像私有注册表并在localhost:32000上公开它
metrics-server：部署度量服务器
prometheus：部署Prometheus Operator v0.25
fluentd：部署Elasticsearch-Kibana-Fluentd日志和监控解决方案
jaeger：在“最简单”的配置中部署Jaeger Operator v1.8.2

More details here: http://curl.haxx.se/docs/sslcerts.html curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option.
