QLoo graphql engine 学习一 基本试用(docker&&docker-compose)

 

说明：使用docker-compose 进行安装

代码框架

使用命令行工具创建

qlooctl install docker qloo-docker

运行qloo&&gloo

• 启动

cd ./qloo-docker
docker-compose up

• 效果
  

配置glooctl &&qlooctl工具

• 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

基本demo

• 启动demo 服务

docker run -d -p 1234:8080 soloio/petstore-example:latest

创建petstore 的gloo upstream

使用使用命令行工具，或者直接编写文件,注意qloo-docker_default 或者根据目录命名修改

• 使用glooctl

cat << EOF | glooctl upstream create -f -
name: petstore
type: static
spec:
  hosts:
  # gateway ip for the docker network
  - addr: $(docker inspect qloo-docker_default -f '{{ (index .IPAM.Config 0).Gateway }}')
    port: 1234
EOF

• 使用配置文件

cat > ./_gloo_config/upstreams/petstore.yaml << EOF 
name: petstore
type: static
spec:
  hosts:
  # gateway ip for the docker network
  - addr: $(docker inspect qloo-docker_default -f '{{ (index .IPAM.Config 0).Gateway }}')
    port: 1234
EOF

查看petsore 函数

 glooctl upstream get

效果

创建graphql schema

• petstore.graphql

# 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
}

• 上传schema(qlooctl 工具)

qlooctl schema create petstore -f petstore.graphql

• 查看注册的resolvermap(实际上就是graphql 的schema &&query && Mutation )

qlooctl resolvermap get petstore-resolvers -o yaml

效果

注册schema 的resolver

# register findPetById for Query.pets (specifying no arguments)
qlooctl resolvermap register -u petstore -f findPetById Query pets
# register a resolver for Query.pet
qlooctl resolvermap register -u petstore -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 petstore -f addPet Mutation addPet --request-template '{{ marshal (index .Args "pet") }}'
