An git based, infrastructure-agnostic deploy tool for #node.js


No single end point

A single API endpoint is a single point of failure. A deployment tool should maintain a cache of API endpoints that can be tried in the case of connection failure.

Differential deployments

Only the delta of the code should be deployed. This significantly improves user experience while reducing the footprint on the network.

Always an interactive REPL

Uses public key infrastructure/cryptography

Binary differential deployments (only deploy your changes)


The program is always run in interactive REPL mode.

Interactive mode (REPL)

Push code to the cloud

Commands push [tag],

Description Attempt to push the code in the current project to the deployment target(s). You may optionally specify a remote for the code push.

Pull code from the cloud

Commands pull [tag],

Description Pull the latest code from for the app. If no version is specified it will pull the latest. If a version is specified, it can be either the sha1 hash for a particular commit or a git tag.

Stop, Restart or Start code

Commands d start [version], d stop [all], d restart

Description Send the application a start, stop or restart signal. These commands are short hand for d sig start, d sig stop and d sig restart.

  • To specify a version of your app to start, supply the git sha1 hash or tag.

  • To stop all of the apps that you have deployed, specify all in addition to stop.

Send an arbitrary signal to the running code

Commands d sig <signal>, sig <signal>

Description Send an arbitrary signal to an application.

Environment variables

Commands env *[name]* *[value]*, env *[name]* *[value]*

Description Environment variables are settings that are applied to the shell environment when a deployment is made. This command will get, set, clear and delete environmental variables.

  • To get all of the variables, omit name and value and all of the currently set variables will be returned. If --json or -j is specified, all of the results will be returned as raw JSON format.

  • To set a variable, supply both the name and the value. If a value contains whitespace, remember to quote it.

  • To get a variable, supply only the name of the variable. This will print only the name and value of that variable.

  • To clear an environment variable for an app, supply only the name of the variable and specify -c. For example: d env <name> -c.

  • To delete environment variable for an app, supply only the name of the variable and specify -d. For example: d env <name> -d.


Commands tail [file]

Description Application logging comes in two flavors. When running this program in interactive mode, you will have real-time logs over tcp. When this program is not running in interactive mode, you will see only a historic view. This historic view is updated when possible and does not represent the most current activity of the application.
