Install Devops-tool

1. Prerequisites

Go installation https://golang.org/doc/install

2. Go to project root (currently installation is for mac)

make install

3. You will need a user with relevant permissions to interact with the tool. Setup aws with the user's credentials

aws configure --profile <your_profile>

4. Add <your_profile> to config.yaml

5. To interact with devops-tool examples

devops-tool help
devops-tool create-efs help
devops-tool delete-efs help

Example creating efs:
devops-tool create-efs -k efskeypair -s efsstack -v vpc-703***09 -m ami-035b3c7efe6d061d5 -n=subnet-49b**02,subnet-55d***79 -c CAPABILITY_NAMED_IAM

Example deleting efs:
devops-tool delete-efs -k efskeypair -s efsstack

Notes

Bug:

pem file created will need to have chmod modified chmod 400 efskeypair.pem before connecting to ec2 instance
