I am using AWS code deploy agent and deploying my project to the server through bitbucket plugin.

The code deployment agent first executes the script files which has the command to execute my spring-boot project.

Since I have two environments one development and another production. I want the script to do things differently based on the environment i.e two different instances.

My plan is to fetch the aws static ip-address which is mapped and from that determine the environment (production or stage).

How to fetch the elastic ip address through sh commands.


Static IP will work.

Here is a more nature CodeDeploy way to solve this is - set up 2 CodeDeploy deployment groups, one for your development env and the other for your production env. Then in your script, you can use environment variables that CodeDeploy will set during the deployment to understand which env you are deploying to.

Here is a blog post about how to use CodeDeploy environment variables:

Associate a Static Public IP Address With Your EC2 Instance, I am using an Amazon EC2 Windows instance and a private IP address was automatically assigned to it. Do I need to assign a static IP address  You can use AWS Global Accelerator to get static IP addresses that act as a fixed entry point to your application endpoints in a single or multiple AWS Regions, such as your Application Load Balancers, Network Load Balancers or Amazon EC2 instances. These IP addresses are announced from multiple AWS edge locations at the same time via anycast, enabling traffic to ingress onto the AWS global network as close to your users as possible.

You could do the following:

id=$( curl )
eip=$( aws ec2 describe-addresses --filter Name=instance-id,Values=${id} | aws ec2 describe-addresses | jq .Addresses[].PublicIp --raw-output )

The above gets the instance-id from metadata, then uses the aws cli to look for elastic IPs filtered by the id from metadata. Using jq this output can then be parsed down to the IP you are looking for.

The solution is completely off tangent to what I originally asked but it was enough for my requirement.

I just needed to know the environment I am in to do certain actions. So what I did was to set an environment variable in an independent script file where the environment variable is set and the value is that of the environment. ex: let's say in a file export profile= stage

In the script file where the commands have to be executed based on the environment I access it this way

 source /test/
    echo current profile is $profile
    if [ $profile = stage ]
        echo stage
    elif [ $profile = production ]
        echo production
        echo failure
