"Spot Requests" has a really useful option called "Maintain target capacity". With this, I am sure that the server will be always there. But there is no way to automatically assign an IP address to the newly created server after the last one was terminated due to higher bidding.
I have to assign the IP address manually even if the server is created automatically.
How to automate this step?
As per one of the blog post, these 2 lines should be saved in user data section of an instance while it is being initiated.
pip install aws-ec2-assign-elastic-ip
/usr/local/bin/aws-ec2-assign-elastic-ip --access-key ACCESS_KEY --secret-key SECRET_KEY --valid-ips IP
Can I use it for persistent spot request?
