atlas-contacts-app

This generated README.md file loosely follows a popular template.

One paragraph of project description goes here.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

Install go dep

go get -u github.com/golang/dep/cmd/dep

Install atlas-db-controller for managing database resources

To create atlas-db custom resource and controller follow link. Make sure to create one if not already exists.
To create database server instance, database and schema/tables resources locally to be used by contacts app, follow

  export GIT_USER=<YOUR_GIT_USER_NAME>
  export GIT_TOKEN=<YOUR_GIT_USER_TOKEN>
  cat deploy/contacts-localdb.yaml | envsubst '$GIT_USER$GIT_TOKEN' | kubectl apply -f -

To create GIT_TOKEN if not exists follow link

To use RDS database instance, database and schema/tables resources used by contacts app, modify contacts-rds.yaml and run"

  kubectl create -f ./deploy/contacts-rds.yaml

Local development setup

Please note that you should have the following ports opened on you local workstation: :8080 :8081 :9090 :5432. If they are busy - please change them via corresponding parameters of gateway and server binaries or postgres container run.

Run PostgresDB:

docker run --name contacts-db -e POSTGRES_PASSWORD=postgres -e POSTGRES_USER=postgres -e POSTGRES_DB=contacts -p 5432:5432 -d postgres:9.4

Table creation should be done manually by running the migrations scripts. Scripts can be found at ./db/migrations/

Create vendor directory with required golang packages

make vendor

Run App server:

go run ./cmd/server/*.go -db "host=localhost port=5432 user=postgres password=postgres sslmode=disable dbname=contacts"

Try atlas-contacts-app

For Multi-Account environment, Authorization token (Bearer) is required. You can generate it using https://jwt.io/ with following Payload:

{
  "AccountID": YourAccountID
}

Example:

{
  "AccountID": 1
}

Bearer

export JWT="eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBY2NvdW50SUQiOjF9.GsXyFDDARjXe1t9DPo2LIBKHEal3O7t3vLI3edA7dGU"

Request examples:

curl -H "Authorization: Bearer $JWT" \
http://localhost:8080/v1/contacts -d '{"first_name": "Mike", "primary_email": "mike@example.com"}'

curl -H "Authorization: Bearer $JWT" \
http://localhost:8080/v1/contacts -d \
'{"first_name": "Robert", "primary_email": "robert@example.com", "nicknames": ["bob", "robbie"]}'

curl -H "Authorization: Bearer $JWT" \
http://localhost:8080/v1/contacts?_filter='first_name=="Mike"'

Note, that JWT should contain AccountID field.

Build docker images

make

Will be created docker images 'infoblox/contacts-gateway' and 'infoblox/contacts-server'.

If this process finished with errors it's likely that docker doesn't allow to mount host directory in its container. Therefore you are proposed to run su -c "setenforce 0" command to fix this issue.

Local Kubernetes setup

Prerequisites

Make sure nginx is deployed in your K8s. Otherwise you can deploy it using

make nginx-up

Deployment

To deploy atlas-contacts-app use

make up

Will be used latest Docker Hub images: 'infoblox/contacts-gateway:latest', 'infoblox/contacts-server:latest'.

To deploy authN stub, clone atlas-stubs repo (https://github.com/infobloxopen/atlas-stubs.git) and then execute deployment script inside authn-stub package or:

curl https://raw.githubusercontent.com/infobloxopen/atlas-stubs/master/authn-stub/deploy/authn-stub.yaml | kubectl apply -f -

This will start AuthN stub that maps User-And-Pass header on JWT tokens, with following meaning:

admin1:admin -> AccountID=1
admin2:admin -> AccountID=2

Usage

Try it out by executing following curl commands:

# Create some profiles
curl -k -H "User-And-Pass: admin1:admin" \
https://$(minikube ip)/atlas-contacts-app/v1/profiles -d '{"name": "personal", "notes": "Used for personal aims"}' | jq

curl -k -H "User-And-Pass: admin1:admin" \
https://$(minikube ip)/atlas-contacts-app/v1/profiles -d '{"name": "work", "notes": "Used for work aims"}' | jq

# Create some groups assigned to profiles
curl -k -H "User-And-Pass: admin1:admin" \
https://$(minikube ip)/atlas-contacts-app/v1/groups -d '{"name": "schoolmates", "profile_id": 1}' | jq

curl -k -H "User-And-Pass: admin1:admin" \
https://$(minikube ip)/atlas-contacts-app/v1/groups -d '{"name": "family", "profile_id": 1}' | jq

Pagination (page token)

DISCLAIMER: it is intended only for demonstration purposes and should not be emulated.

Contacts App implements pagination in by adding application specific page token implementation.

Actually the service supports "composite" pagination in a specific way:

limit and offset are still supported but without page token
if an user requests page token and provides limit then limit value will be used as a step for all further requests page_token = null & limit = 2 -> page_token=base64(offset=2:limit=2)
if an user requests page token and provides offset then only first time the provided offset is applied page_token = null & offset = 2 & limit = 2 -> page_token=base64(offset=4:limit=2)

Get all contacts: GET http://localhost:8080/v1/contacts

{
  "results": [
    {
      "emails": [
        {
          "address": "one@mail.com",
          "id": "1"
        }
      ],
      "first_name": "Mike",
      "id": "1",
      "primary_email": "one@mail.com"
    },
    {
      "emails": [
        {
          "address": "two@mail.com",
          "id": "2"
        }
      ],
      "first_name": "Mike",
      "id": "2",
      "primary_email": "two@mail.com"
    },
    {
      "emails": [
        {
          "address": "three@mail.com",
          "id": "3"
        }
      ],
      "first_name": "Mike",
      "id": "3",
      "primary_email": "three@mail.com"
    }
  ],
  "success": {
    "status": 200,
    "code": "OK"
  }
}

Default pagination (supported by atlas-app-toolkit): GET http://localhost:8080/v1/contacts?_limit=1&_offset=1

{
  "results": [
    {
      "emails": [
        {
          "address": "two@mail.com",
          "id": "2"
        }
      ],
      "first_name": "Mike",
      "id": "2",
      "primary_email": "two@mail.com"
    }
  ],
  "success": {
    "status": 200,
    "code": "OK"
  }
}

Request specific page token: GET http://localhost:8080/v1/contacts?_page_token=null&_limit=2

{
  "results": [
    {
      "emails": [
        {
          "address": "one@mail.com",
          "id": "1"
        }
      ],
      "first_name": "Mike",
      "id": "1",
      "primary_email": "one@mail.com"
    },
    {
      "emails": [
        {
          "address": "two@mail.com",
          "id": "2"
        }
      ],
      "first_name": "Mike",
      "id": "2",
      "primary_email": "two@mail.com"
    }
  ],
  "success": {
    "status": 200,
    "code": "OK",
    "_page_token": "NDo0"
  }
}

Get next page via page token: GET http://localhost:8080/v1/contacts?_page_token=NDo0

{
  "results": [
    {
      "emails": [
        {
          "address": "three@mail.com",
          "id": "3"
        }
      ],
      "first_name": "Mike",
      "id": "3",
      "primary_email": "three@mail.com"
    }
  ],
  "success": {
    "status": 200,
    "code": "OK",
    "_page_token": "NTo0"
  }
}

Get next page: GET http://localhost:8080/v1/contacts?_page_token=NTo0 The "_page_token": "null" means there are no more pages

{
  "success": {
    "status": 200,
    "code": "OK",
    "_page_token": "null"
  }
}
