How to export Amazon EC2 instances to a CSV file


Amazon website is limited to 50 instances per page. Viewing lots of instances is a pain and it doesn’t support exporting to CSV/TSV/Excel/other out of the box. The only fix is to use the CLI.

Requirements

  • An AWS account with access rights to see your servers
  • A pair of AWS keys (Users -> [username] -> Security Credentials -> Create Access Key)
# Install AWS packages
sudo apt-get install -y python python-pip
sudo pip install aws-shell

Listing Instances

# aws-shell will show a wizard to configure your account and region the first time you use it
aws-shell
ec2 describe-instances --output text --query 'Reservations[*].Instances[*].[InstanceId, InstanceType, ImageId, State.Name, LaunchTime, Placement.AvailabilityZone, Placement.Tenancy, PrivateIpAddress, PrivateDnsName, PublicDnsName, [Tags[?Key==`Name`].Value] [0][0], [Tags[?Key==`purpose`].Value] [0][0], [Tags[?Key==`environment`].Value] [0][0], [Tags[?Key==`team`].Value] [0][0] ]' > instances.tsv
# open instances.tsv with Excel
# enjoy

You can modify the command to pick the information you want. Refer to the official AWS command line reference.

  1. thanks that works. If you want to get instances with name in tabular format use the below command

    aws ec2 describe-instances –output text –query ‘Reservations[*].Instances[*].[InstanceId, State.Name, [Tags[?Key==`Name`].Value] [0][0] ]’ –output table

  2. Thank you very much HFT guy for this tip! I was asked to generate a list our AWS instances for coporate SecOps team, and found I could not simply export from console. I had to change ‘ to ” before Reservations and at the end before the >. But this worked for me. I ran it from from a windows 10 laptop with AWS CLI installed. Note also, I used –profile to supply the aws credentials needed for our awsprod environment (we have a test/dev environment too :
    aws –profile awsprod ec2 describe-instances –output text –query “Reservations[*].Instances[*].[InstanceId, InstanceType, ImageId, State.Name, LaunchTime, Placement.AvailabilityZone, Placement.Tenancy, PrivateIpAddress, PrivateDnsName, PublicDnsName, [Tags[?Key==`Name`].Value] [0][0], [Tags[?Key==`purpose`].Value] [0][0], [Tags[?Key==`environment`].Value] [0][0], [Tags[?Key==`team`].Value] [0][0] ]” > c:\instances.tsv
