问题
I would like to communicate with AWS Batch jobs from a local R process in the same way that Davis Vaughn demonstrated for EC2 at https://gist.github.com/DavisVaughan/865d95cf0101c24df27b37f4047dd2e5. The AWS Batch documentation describes how to set up a key pair and security group for batch jobs. However, I could not find detailed instructions about how to find the IP address of a job's instance or what user name I need. The IP address in particular is not available in the console when I run the job, and aws batch describe-jobs --jobs prints out an empty "jobs": [] JSON string. Where do I find the information I need to ssh into a job's instance? (In my use case, I would prefer the IP address instead of the host name.)
