Aws-cli: Retrieving the IP address for an EC2 instance given its <instance ID>

[amelio-vazquez-reina]

Does the CLI have any commands that can be used to retrieve the _private IP_ of an EC2 instance given the instance ID ?

What if I provide a tag instead?

aws ec2 describe-instances --instance-id i-3f3f3f3f

if you have jq installed…

instance_id=aws ec2 describe-instances --instance-id i-3f3f3f3f| jq —raw-output .Reservations[].Instances[].PrivateIpAddress

Thanks @digitaljedi2 Your JQ solution worked

@ribonoous Also, you can use the --query option to avoid having an additional dependency. aws ec2 describe-instances --instance-id i-12345 --query 'Reservations[].Instances[].PrivateIpAddress'.

Adding on top @jamesls answer:

aws ec2 describe-instances --instance-id i-0329b8ad --query 'Reservations[].Instances[].PrivateIpAddress' | grep -vE '\[|\]' | awk -F'"' '{ print $2 }'

This way you end up with a clean output.

There's also an extra param you can pass to describe-instances to accomplish the same thing:

aws ec2 describe-instances \
  --instance-id i-0329b8ad \
  --query 'Reservations[].Instances[].PrivateIpAddress' \
  --output text

thy are all wrong... it seems the --instance.id is ignored and ALL instances are shown always
