QLoo graphql engine 学习二 基本试用(kubernetes)

已经测试过docker&& docker-compose 的运行模式，下面测试下kubernetes的运行模式

kubernetes 我使用docker for mac

qloo 安装

• 下载

https://github.com/solo-io/qloo/releases
https://github.com/solo-io/gloo/releases

• 配置环境变量

  mac

cat ~/.bash_profile
export PATH=$PATH:/Users/dalong/Downloads/qloo

部署gloo&&qloo

使用命令行工具,有一个问题，需要先创建 gloo-system namespace，好像是一个bug

    qlooctl install kube

部署petsotre 服务

 kubectl apply \
      -f https://raw.githubusercontent.com/solo-io/gloo/master/example/petstore/petstore.yaml

查看函数（glooctl）

    glooctl upstream get

创建schema （与docker-compose 是一样的）

# The query type, represents all of the entry points into our object graph
type Query {
    pets: [Pet]
    pet(id: Int!): Pet
}

type Mutation {
    addPet(pet: InputPet!): Pet
}

type Pet{
    id: ID!
    name: String!
    status: Status!
}

input InputPet{
    id: ID!
    name: String!
    tag: String
}

enum Status {
    pending
    available
}
qlooctl schema create petstore -f petstore.graphql

注册resolver

# register findPetById for Query.pets (specifying no arguments)
qlooctl resolvermap register -u default-petstore-8080 -f findPetById Query pets
# register a resolver for Query.pet
qlooctl resolvermap register -u default-petstore-8080 -f findPetById Query pet
# register a resolver for Mutation.addPet
# the request template tells QLoo to use the Variable "pet" as an argument 
qlooctl resolvermap register -u default-petstore-8080 -f addPet Mutation addPet --request-template '{{ marshal (index .Args "pet") }}'

访问方式

查询操作

{
  pet(id:1 ) {
    name
  }
}
