go-ec2-describe-tags

AWS ec2-describe-tags as a standalone executable

Written in golang. Precompiled binary for Linux fully linked and executable on any x86 Linux distro including Alpine Linux. Precompiled binary for MacOSX.

Motivation

Need to populate fleet's metadata with the instance tags. As a consequence:

• curl and bash are not enough to read tags
• Can't install python and awscli on CoreOS
• Cant wait for Docker to be ready and run a containerised awscli
• Lazy download of a single executable calls on the CLI works.

Usage

wget https://github.com/hmalphettes/go_ec2_describe_tags/release/.../ec2_describe_tags
# wget https://github.com/hmalphettes/go_ec2_describe_tags/release/.../ec2_describe_tags_macos

ec2_describe_tags -access_key=XXX -access_secret_key=YYYYY -region=us-east-1 -instance_id=zzzzzz
Name=testing

Environment variables for default values:

• Access key and secret key defaults to environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.
• Region default to the environment variable AWS_REGION
