serverless (AWS lambda) + AWS mongodb cluster

照這個教學
https://s3.amazonaws.com/quickstart-reference/mongodb/latest/doc/MongoDB_on_the_AWS_Cloud.pdf

1. 選　new VPC　
2. 會到 cloudformation
3. 下一步
1. Availability Zones <=要全選
2. Number of Availability Zones　<=全部
3. Allowed Bastion External Access CIDR Allowed CIDR <= 0.0.0.0/0
4. Key Pair Name <= key選本機原有的就好了<=之後還要從本機copy到，他開的機器，做ssh 的測試。
5. MongoDB Admin Username  ...
6. MongoDB Admin Password ...
4. 下一步
5. 約20分鐘
6. 會開出兩台 ec2
1. LinuxBastion <= 測試你的 mongo cluster 用的
2. PrimaryReplicaNode0 <= mongo cluster 只有 vpc 能連
7. pdf 的測試方式為
1. scp -i key .... 到 LinuxBastion
   scp –i mykey.pem mykey.pem ec2-user@Bastion-public-ip:/home/ec2-user/mykey.pem
2. ssh  - i key PrimaryReplicaNode0的ip
3. mongo 
   mongo
   use admin
   db.auth("admin", "YourAdminPassword") rs.printReplicationInfo()
   rs.status()
8. 應該都正常了

===lambda

1. 我直接改這個範例做測試
   https://github.com/serverless/examples/tree/master/aws-node-rest-api-mongodb
2. 
   service: aws-node-rest-api-mongodb

   
   

   provider:

   name: aws

   region: ap-northeast-1 //記得region 要設對，不然找不到 sg

   runtime: nodejs6.10

   vpc:

   securityGroupIds:

   - "sg-db38a1xx" //加這個

   subnetIds:

   - "subnet-39dd6bxx" //加這個

   - "subnet-44e59exx" //加這個

   
   

   functions:

   createUser:

   handler: handler.createUser

   events:

   - http:

   path: user

   method: post

   cors: true

   vpc:

   securityGroupIds:

   - "sg-db38a1xx" //加這個

   subnetIds:

   - "subnet-39dd6bxx" //加這個

   - "subnet-44e59exx" //加這個




3. securityGroupIds  <= 來自ec2 => PrimaryReplicaNode0 => Security groups
    => 點進去 => 看 Source
4. Subnet ID <= 來自ec2 => PrimaryReplicaNode0 => Subnet ID 
5. sls deploy

endpoints:

  POST - https:// x.execute-api.ap-northeast-1.amazonaws.com/dev/user

  PUT - https://x.execute-api.ap-northeast-1.amazonaws.com/dev/user/{id}

  DELETE - https://x.execute-api.ap-northeast-1.amazonaws.com/dev/user/{id}

  GET - https://x.execute-api.ap-northeast-1.amazonaws.com/dev/user/{id}

照這個試試吧！

結束！
