I have an ASG with min=2, max=4 configuration. In the boot up script of each EC2, I have a series of yum install and starting of 2 spring boot files. Now, when th e load increases and ASG spins up a new EC2 instance, it will perform all these in the boot up script.
Could anybody suggest a good method to validate whether all these yum installs have been successful and also whether the 2 spring boot files are running currently. If there is any problem with these, I dont want the EC2 instance to be attached to ELB.
