envchain --set isucon IKA_USER IKA_HOSTS

IKA_USER : fukajun

IKA_HOSTS : isu1,isu2,isu3

config

edit .ssh/config

Host isu1
  HostName 10.0.0.1
  User ec2-user
  IdentityFile ~/.ssh/id_rsa.isucon.pem
  Port 22
Host isu2
  HostName 10.0.0.2
  User ec2-user

Usage

local and all hosts setup dir

envchain isucon ./bin/ika_sync init

upload to all hosts from local IKA_USER dir

envchain isucon ./bin/ika_sync up

download from all hosts to local IKA_USER dir

envchain isucon ./bin/ika_sync down

download from all hosts all user to local dir

envchain isucon ./bin/ika_sync down_all

First step

1. init
2. up
