CPLOY

The ad hoc continuous deployment solution for developers

I sometimes have to code stuff that needs to be run on remote hosts. Since I don’t have all my prefs/settings/dotfiles/etc on the remote, I usually code on local and have a small one-liner lying around that allows me to quickly deploy the code (with scp or similar) and run some command on the other side (with ssh for example). This is not optimal and that’s the reason I created cploy.

Cploy allows to mirror changes performed on a local directory to a remote host through SSH. A specific command (bash oneliner for example) can be run after any change for example to trigger a build.

Features:

• handle multiple syncs in parallel

• sync is done through SSH

• can be daemonized

• allows to provide a specific command to run on each local change

• allows to exclude some files from sync

Quick start:

# install cploy
sudo pip3 install cploy
# start the daemon
cploy daemon start
# add a directory to sync
cploy sync /tmp/local someuser@somehost /tmp/remote

Installation

To install run:

$ sudo pip3 install cploy

Or from github directly

$ cd /tmp; git clone https://github.com/deadc0de6/cploy && cd cploy
$ sudo python3 setup.py install
$ cploy --help

To work with cploy without installing it, you can do the following

$ cd /tmp; git clone https://github.com/deadc0de6/cploy && cd cploy
$ sudo pip3 install -r requirements.txt
$ python3 -m cploy.cploy --help

or install it in a virtualenv

$ cd /tmp; git clone https://github.com/deadc0de6/cploy && cd cploy
$ virtualenv -p python3 env
$ source env/bin/activate
$ python setup.py install
$ cploy --help

Usage

The usual way of using cploy is by starting the daemon and adding tasks to it (directories to sync between local and a remote host).

Start the daemon

$ cploy daemon start --debug

and then add tasks to it:

# sync dir /tmp/local on localhost to
# /tmp/remote on host somehost
$ cploy sync /tmp/local/ somehost /tmp/remote

Usage:

cploy
Usage:
    cploy sync [-dfF] [-p <port>] [-u <user>] [-P <pass>]
        [-k <key>] [-K <pass>] [-c <cmd>] [-e <pattern>...]
        <local_path> <hostname> <remote_path>
    cploy daemon [-d] (start | stop | restart)
    cploy daemon [-d] (info | ping | debug)
    cploy daemon unsync <id>
    cploy daemon resync <id>
    cploy --help
    cploy --version

Options:
    -p --port=<port>          SSH port to use [default: 22].
    -u --user=<user>          username for SSH [default: drits].
    -k --key=<key>            Path of SSH private key to use.
    -P --pass=<pass>          SSH password to use.
    -K --keypass=<pass>       SSH private key passphrase.
    -e --exclude=<pattern>    Pattern to exclude using fnmatch.
    -c --command=<cmd>        Command to execute on changes.
    -F --front                Do not daemonize.
    -f --force                Force overwrite on remote [default: False].
    -d --debug                Enable debug [default: False].
    -v --version              Show version.
    -h --help                 Show this screen.

Remote host

Connections to a remote hosts is done using SFTP (SSH). Multiple options can be changed: connection with password, with SSH keys, using the SSH agent, different port, different username, etc.

Besides using the above options, The ** argument can also be provided using a format similar to what the SSH client provides: @:.

Talking with the daemon

A few commands are available to talk to the daemon:

• start: start the daemon

• stop: stop the daemon

• restart: stop and then start the daemon

• info: get a list of current tasks

• ping: ping the daemon

• debug: toggle debug flag

• unsync: stop syncing a specific task

• resync: do a full sync starting from local of the sync’ed directory

If you prefer not to use the daemon, it can also be run in the foreground by using the --front switch.

Excluding

Files can be excluded within the monitored directory by using --exclude. Matching is done using fnmatch.

Exclude any hidden files:

--exclude '*/.*'

Exclude any files containing test

--exclude '*/test*'

Issues and bugs

This hasn’t been extensively tested so please do report any bug you find. Starting the daemon with --debug is always helpful to get more info (or toggle it with the daemon command debug).
