node-i2cssh

i2cssh with the support of osascript and node. It is highly inspired by the original i2cssh and the AppleScript version of it (i2cssh). It only runs from within iTerm2 (>2.9)!. The goal of this project is to create an alternative that is working with the newest iTerm2 and enhance it with features for the cloud like ssh to all ec2 instances that have a special tag.

Installation

npm -g install node-i2cssh

Usage

i2cssh 1.example.com 2.example.com 3.example.com

Configuration

by default, node-i2cssh is checking for a file called .i2csshrc in the users home directory. This can be overwritten with the -C option. see i2csshrc.example.yml for an annotated example configuration

Options

-C --config

overwrites the default config file location i2cssh -C ~/workspace/gitrepo/i2csshconfig.yml

-c --clusters

adds the given clusters hosts from the config to the hosts to connect to. i2cssh -c dev -c staging

-b --broadcast

starts the broadcast mode immediatly after all tabs are created i2cssh -b foo1.bar foo2.bar foo3.bar

-t --tags

ec2 tag in the format of $NAME=$VALUE (the = separator can be overridden in .i2csshrc -- see i2csshrc.example.yml). i2cssh -t env=staging -t end=dev Optionally: you can run i2cssh -t to get asked to which tag you want to connect to. Downside: you can only choose one key-value pair.

-u --user

Change the username to connect with i2cssh -u philipp foo1.bar results in ssh philipp@foo1.bar

EC2 Integration

For the EC2 integration to work, you need to have AWS_SECRET_ACCESS_KEY and AWS_ACCESS_KEY_ID set as environment variables. I recommend using envchain and creating some alias for i2cssh wrapping it into envchain like alias i2cssh="envchain aws i2cssh $@" You'll also need to defined the aws region in your .i2csshrc. see the example config for more information
