mixer

1. mixer server实例初始化
2. 校验内置的adapters与templates的HandlBuilder接口关系
3. 后端存储配置的client初始化
4. runtime环境的初始化，非常重要
5. mixc调用mixs的处理流程
6. 手把手编写template和adapter

etcd v3实用命令

# 列出所有的key, 
#  1. --keys-only=true, 只显示key。不显示对应的value值;
#  2. --limit=100, 列出的key数量限制在1000
ETCDCTL_API=3 etcdctl get / --limit=1000 --prefix --keys-only=true > tmp

# 列出所有与mixer server相关配置文件的keys
ETCDCTL_API=3 etcdctl --prefix=true get /registry/config.istio.io --keys-only=true

# 列出自定义的adapter={myperson}
ETCDCTL_API=3 etcdctl get /registry/config.istio.io/adapters/istio-system/myperson

# 列出自定义的template={person}
ETCDCTL_API=3 etcdctl get /registry/config.istio.io/templates/istio-system/person

下面展示自定义template与adapter作为配置文件存储在k8s中的所有相关key
