Hubot masters aws commands

I wrote a guest blog published by PacktPub about a quick intro to this npm module. See https://www.packtpub.com/books/content/part2-chatops-slack-and-aws-cli.

Installation

Add hubot-aws to your package.json file:

npm install --save hubot-aws

Add hubot-aws to your external-scripts.json:

["hubot-aws"]

Run npm install

Auth

Access Control with hubot-auth.

  • User with admin or the role defined HUBOT_AWS_CAN_ACCESS_ROLE can run all commands.
# against user without a valid role
hubot> hubot ec2 run
You cannot access this feature. Please contact an admin.
  • You can disable access control like below.
export HUBOT_AWS_DEBUG="1"

Commands

SNS

Configuring

In addition to administration of SNS, hubot-aws can also receive push notifications.

  • Create a new SNS topic
  • Create a subscription and choose HTTP(S). The default configuration is http://:8080/hubot/sns
    • The URL can be set using HUBOT_SNS_URL
  • Set HUBOT_SNS_JID to hubot's jabber ID

You should see the subscription ID change from PendingConfirmation to a valid subscription id.

Receiving Messages

Use the Subject property to set which room the message should be delivered in, usually its JID. Messages can be raw or JSON format, but JSON is preferred. If you are using hubot-hipchat use the plain old room name for the Subject. The Subject property does not accept multiple rooms. Additionally the Messages does not natively process html templates, but one could implement it.

Sending Messages

hubot-aws does not send the message to a chat room. This is due to the myriad of adapters and clients hubot supports. To process a message and send it to your chat room, hook into the sns:notification event.

# Use this snippet in your own scripts to send messages to the chat room from SNS
robot.on 'sns:notification', (message) ->
  # if using HipChat the channelID function converts the common name to the room JID
  robot.messageRoom sns.channelID(message.subject), message.message
  # if using another adapter
    robot.messageRoom message.subject, message.message

Recommended Usage

Use --dry-run

hubot> hubot ec2 run --dry-run
Requesting dry-run=true...
{ MinCount: 1,
  MaxCount: 1,
  DryRun: false,
  ImageId: 'ami-AAA',
  KeyName: 'aws',
  InstanceType: 't2.micro',
  Placement: { AvailabilityZone: 'ap-northeast-1a' },
  NetworkInterfaces:
   [ { Groups: [ 'sg-AAA' ],
       SubnetId: 'subnet-AAA',
       DeviceIndex: 0,
       AssociatePublicIpAddress: true } ],
  UserData: 'IyEvYmluL2Jhc2gKCiMgc2V0dXAgc3RhcnQgbm90aWZ5CkhPU1RfTkFNRT1gaG9zdG5hbWVgCg...

# Then, remove --dry-run option
hubot> hubot ec2 run
...

Use hubot-env

You can switch environment variables about AWS Account Credentials via hubot command dynamically, if you want to manage multi accounts.

# Load new environment variables abount AWS credentials of account 1.
hubot> hubot env load --filename=aws-cred-account1.env
Loading env --filename=aws-cred-account1.env, --dry-run=false...
HUBOT_AWS_CREDENTIALS=account1
HUBOT_AWS_ACCESS_KEY_ID=ACCESS_KEY1
HUBOT_AWS_SECRET_ACCESS_KEY=***
HUBOT_AWS_REGION=ap-northeast-1

# Then, Switch to overwrite environment variables abount AWS credentials of account 2.
hubot> hubot env load --filename=aws-cred-account2.env
Loading env --filename=aws-cred-account2.env, --dry-run=false...
HUBOT_AWS_CREDENTIALS=account2
HUBOT_AWS_ACCESS_KEY_ID=ACCESS_KEY2
HUBOT_AWS_SECRET_ACCESS_KEY=***
HUBOT_AWS_REGION=ap-northeast-1

Use hubot-hint

hubot-awssupports many commands and some commands require multi arguments. hubot-hint shows rest of command help.

# Search commandHelps with `autoscaling launch`
hubot> hubot autoscaling launch hint
hubot>
hubot autoscaling launch create --name=[launch_configuration_name] # Create an AutoScaling LaunchConfiguration
hubot autoscaling launch create --name=[launch_configuration_name] --dry-run # Try creating an AutoScaling LaunchConfiguration
hubot autoscaling launch delete --name=[launch_configuration_name] # Delete the AutoScaling LaunchConfiguration
hubot autoscaling launch ls # Displays all AutoScaling LaunchConfigurations
hubot autoscaling launch ls --name=[launch_configuration_name] # Details an Autoscaling LaunchConfiguration

# Search commandHelps with `autoscaling launch create`
hubot> hubot autoscaling launch create hint
