Overview

Package innerdomain , interconversion between k8s & marathon internal domain

旧版本的内部地址格式

<servicename>.<servicegroup-name>.<servicegroup-namespace>.<suffix1>.<suffix2>.marathon.l4lb.thisdcos.directory

e.g. (marathon) prototype.prod-6056.services.v1.runtimes.marathon.l4lb.thisdcos.directory (k8s) 不存在旧版本k8s地址 (marathon) consul.consul-afdb5eb0327848e19f3d414eb345dfdd.addons-2126.v1.runtimes.marathon.l4lb.thisdcos.directory (k8s) 不存在旧版本k8s地址

新版本的内部地址格式

marathon:

<servicename>.<namespace>.marathon.l4lb.thisdcos.directory

k8s:

<servicename>.<namespace>.svc.cluster.local

_LIMIT_: <namespace> 最长63位, <namespace> 必须保持唯一

e.g. (marathon) blog-service.<namespace>.marathon.l4lb.thisdcos.directory (k8s) blog-service.<namespace>.svc.cluster.local

Functions

func MustParseWithEnv

func MustParseWithEnv(originAddr string, k8s bool) string

func ParseWithEnv

func ParseWithEnv(originAddr string, k8s bool) (string, error)

ParseWithEnv

Types

type InnerDomain

type InnerDomain struct {
	// contains filtered or unexported fields
}

InnerDomain 代表内部地址

func New

func New(servicename, namespace string) (InnerDomain, error)

New 根据 servicename, namespace 构建 InnerDomain

func Parse

func Parse(originAddr string) (InnerDomain, error)

Parse 从 host 解析出 InnerDomain

func (*InnerDomain) K8S

func (i *InnerDomain) K8S() (string, error)

K8S 生成 k8s 版本的内部地址

func (*InnerDomain) Marathon

func (i *InnerDomain) Marathon() (string, error)

Marathon 生成 marathon 版本的内部地址

func (*InnerDomain) MustK8S

func (i *InnerDomain) MustK8S() string

MustK8S 类似 K8S，如果出错则panic

func (*InnerDomain) MustMarathon

func (i *InnerDomain) MustMarathon() string

MustMarathon 类似 Marathon，如果出错则 panic
