shell script to deploy and start a node app via ssh

deploy.md

A simple starter script to copy a node app to a remote host and start it over ssh.

Not very robust in terms of order-dependent argument handling. Arguments have defaults, but if you provide a value for one, any preceding args must also be supplied.

Arguments

1. The source directory. Defaults to current directory.
2. The destination server for the ssh connection.
3. The port to run the app on the destination server. Defaults to port 80.

#!/bin/sh

# source
DIR=${1:-`pwd`}
DIRPATH=$(dirname $DIR)

# destination
HOST=${2:-default.server.com}
APPPORT=${3:-80}
TARGETPATH=node
DIRNAME=$(basename $DIR)

# don't want to be prompted by ssh for first time remote hosts.
alias ssh='ssh -o StrictHostKeyChecking=no'

# push app to host
# ssh root@$HOST 'cd node; rm -rf *' 
cd $DIRPATH; tar czf - $DIRNAME | ssh root@$HOST '(cd $TARGETPATH; rm -rf *; tar xzf -)' 

# start app
# ssh root@$HOST "cd $TARGETPATH/$DIRNAME; PORT=$APPPORT; npm start"
