awsops
A Go based CLI and Serverless functions for common AWS operations
This library is a bit scrappy and very opinionated for executing operational processes on AWS the way we like to.
Installation
If you don't care to modify the source, you can grab a prebuilt binary from Releases.
You can also clone this repo and use go build to build a binary or go run to run it directly. Or simply run make to build for multiple
platforms.
Configuration
This app makes use of the AWS Go SDK - https://docs.aws.amazon.com/sdk-for-go/api/
This library makes use of standard AWS CLI configurations such as the ~/.aws/credentials file. If you don't already use the AWS CLI, the easiest way to configure your system is to create a .aws folder in your home directory and a credentials file inside that directory. The format of the file should be:
[nameofprofile]
aws_access_key_id = value
aws_secret_access_key = value
Then when using awsops you can use the -p flag followed by whatever profile from the credentials file you want to use. For example: awsops -p default ...

awsops ecs [flags]
awsops ecs [command]
Available Commands:
listInstanceIPs List Instance IPs for ECS Cluster
replaceInstances Gracefully replace EC2 instances for given ECS cluster

$ awsops ecs listInstanceIPs --help
Command returns a space separated list of IP addresses for instances in an ECS cluster
Usage:
awsops ecs listInstanceIPs [flags]
Flags:
-h, --help help for listInstanceIPs
Global Flags:
-c, --cluster string ECS cluster name
--config string config file (default is $HOME/.awsops.yaml)
-p, --profile string AWS shared credentials profile to use
-r, --region string AWS shared credentials profile to use (default "us-east-1")
$ awsops ecs replaceInstances --help
Gracefully replace EC2 instances for given ECS cluster
Usage:

Global Flags:
-c, --cluster string ECS cluster name
--config string config file (default is $HOME/.awsops.yaml)
-p, --profile string AWS shared credentials profile to use
-r, --region string AWS shared credentials profile to use (default "us-east-1")
$ awsops ecs rightSizeCluster --help
This command calculates total memory and CPU needed
for all services in the given ECS cluster and then adjusts
instance count in the ASG based on instance type/size to
support running all tasks with as few servers as is needed.
This function may scale a cluster up or down depending on services.
Usage:
awsops ecs rightSizeCluster [flags]
Flags:
-h, --help help for rightSizeCluster
Global Flags:
-c, --cluster string ECS cluster name
--config string config file (default is $HOME/.awsops.yaml)
-p, --profile string AWS shared credentials profile to use
-r, --region string AWS shared credentials profile to use (default "us-east-1")
