I have an Elastic Beanstalk environment with load balancer. Also I have an hosted zone associated with the load balancer in order to access the environment via custom domain name.

Now I want a static IP to use in Tableau Trusted Authentication. I am confused. I can't figure out from where I can get the required static IP.

The answer accepted on this question is 5 years old and things have changed since then.

Sadly there is no way to auto asign an Elastic-ip on a load balancer since AWS only provides support for the DNS.

But there is another solution, to add a script that auto asign an ip to an instance on boot. As the next references suggest.

https://support.asperasoft.com/hc/en-us/articles/216129788-Server-on-Demand-with-EIP-and-Autoscale#prereqs

https://blog.cloudthat.com/auto-attach-elastic-ip-to-ec2-classic-instance-for-autoscaling/

https://github.com/skymill/aws-ec2-assign-elastic-ip

You need to do the next steps:

  1. Set aside as many elastic ip as the max number of instances in your Auto Scaling Group

  2. Create an instance with the current Elastic Beanstalk AMI

  3. Install aws-ec2-assign-elastic-ip using python's pip.

  4. Add the current script to the instance

    #!/bin/sh
#
# This script is launched at boot, and assigns an AWS elastic ip.

AWS_ACCESS_KEY_ID=#<acces_key_value>#
AWS_SECRET_ACCESS_KEY=#<Secret_key_Value>#

#Regions Virgina: us-east1   Oregon: us-west2 ...
AWS_DEFAULT_REGION=#<EB_ENV_REGION>#

#Set of valid IP comma(,) separated
VALID_IP_VALUES=<IP_VALUE>,<IP_VALUE>,<...>


/usr/local/bin/aws-ec2-assign-elastic-ip --region  $AWS_DEFAULT_REGION --access-key $AWS_ACCESS_KEY_ID --secret-key $AWS_SECRET_ACCESS_KEY --valid-ips $VALID_IP_VALUES

  5. Add this script at /etc/rc.local

    bash /usr/local/bin/auto-assign-eip.sh

  6. Create a new base AMI using this instance, and set it as your EB AMI.

You mean you want to access the elastic beanstalk application using Static IP? If you want to access your application using static IP then go and spin up a EC2 and deploy your application. The assign a static Elastic IP to that instance. Elastic IP is a static public IP which wont change unless you release it. For more about AWS Elastic IP see the below link.

  • I tried assocating an elastic IP to ec2 instance but it didn't work. I guess I need to associate IP to elastic beanstalk load balancer. – ujjwal garg Jan 04 '18 at 13:31
