This utility is to be able to connect and run multiple commands either parallel sequential or in groups (based on sshkit https://github.com/capistrano/sshkit)

seperate commands with a semicolon

default region: us-east-1 default user: ec2-user default connnection :parallel

Groups were designed in this case to relieve problems (mass Git checkouts) where you rely on a contested resource that you don't want to DDOS by hitting it too hard.

Sequential runs were intended to be used for rolling restarts, amongst other similar use-cases.

--terminal will open multiple terminals windows of all servers found (currently only supported on OSX iTerm2)

Usage: ec2-ssh connect --cmd=CMD

Options: --cmd=CMD # commmand to run on remote servers [--profile=PROFILE] # aws cli profile # Default: default [--region=REGION] # region # Default: us-east-1 u, [--user=USER] # run as user # Default: ec2-user p, [--parallel=PARALLEL] # run in parallel s, [--sequence=SEQUENCE] # run in sequence g, [--groups=GROUPS] # run in groups l, [--groups-limit=N] # limit w, [--wait=N] # wait [--as=AS] # get autoscale groups [--tag-key=TAG_KEY] # tag key to filter instances by # Default: Name [--tag-value=TAG_VALUE] # tag value to filter instances by t, [--terminal=TERMINAL] # open terminal tabs for all servers

Connect to autoscale instance (random instance), Pass --cmd='whatever' to run a cmd on the server
