The iNeuron AWS Deployer.

#### Installation

NPM Install the package

``npm i @ineuronintelligence/ineuron-aws-deployer`

#### Available Services

[ ] `getPreProdInstance`- Takes a param string (appName) make sure`tag:Instance-Depl-Type` & `tag:Usable` & `tag:AppName` exists in the instance (Pre Production Instance).

[ ] `createAMIImage` - Takes params like (InstanceId, name, version), Here `InstanceId` - Pre-Prod InstanceId, `name` - appName, `version` - appVersion. - It is prefer to use npm package version and name of the particular project which is using this feature.

[ ] `createLC` - Takes params like (name, version, ImageId, InstanceType, KeyName, SecurityGroup, VolumeSize), This created a new Launch Configuration for auto-scaling.

[ ] `checkImageIsReady` - Takes param like (AMIImageId), This checks if the image is created and has become available.

[ ] `getASLConfig` - Takes params like (name, version). This is provides information about newly created auto scaling launch configuration.

[ ] `describeASGroups` - Takes param like (AutoScalingGroupName), This provides information about the autoscaling group which we want to correctly configure.

[ ]`updateASGroup` - Takes params like (AutoScalingGroupName, LaunchConfigurationName), Using the AutoScalingGroupName we update the launch configuration with the newly created launch configuration which contains new AMIImage.

[ ] `updateListenerRules` - Takes params like (albName, blueTGName, greenTGName, blueTGWeight, greenTGWeight). These events are triggered when the new AMIImage is ready and the new launch configuration is updated in the auto scaling group. This function updates the listener rules of the ALB to point to the new target group.

[ ] `startInstanceRefreshNow` - Takes param like (AutoScalingGroupName). Now that we have updated the listener rules with the new target group, we refresh the AutoScalingGroup to use the new Launch Configuration, This will take a while. Termination, Decommission the old instance and firing new instance.

[ ] `describeInstanceRefresh`` - Takes params like (InstanceRefreshId, AutoScalingGroupName). This checks if the instance refresh status is completed.

Make sure you have tagged the instance with recommended tags.

Once the instanceRefresh is completed move the traffic from Blue TargetGroup of the Application Load Balancer to Green TargetGroup of the Application Load Balancer which is assigned to the AutoScalingGroup.

Use the updateListenerRules Service to update the weights of the targetgroup accordingly.
