Integrating Eureka and Asgard

Asgard the web based cloud deployment tool can be used with Eureka to mitigate problems during a rolling deployment in a AWS autoscaling group and for seamlessly switching between old and new deployments.

Rolling Deployment

During a rolling deployment, Asgard can check for the health of an instance before propagating the new version to all of the instances in an ASG(Autoscaling group). This is a useful risk mitigation strategy for preventing outages if the new version has problems for some reason.

To use this feature, eureka clients are required to register a health check URL.This can be done in 2 ways

• By specifying a relative health check url path given by the property below

eureka.healthCheckUrlPath

eureka.healthCheckUrl
eureka.secureHealthCheckUrl
