hms

Work in progress. Ship all kinds of services

npm install -g hms

Afterwards you should have an command line tool called hms.

Getting started

First ssh to a remote server and install hms. Then start up a terminal.

hms terminal # starts both a terminal and a dock

In a new folder start the dock (or multiple docks as seperate processes). The dock will run your apps

hms dock [url-to-a-terminal] --tag my-dock # add a some tags

Then on your local machine add the remote

hms remotes add my-remote username@your-server.com

hms uses ssh to contact the server so username@your-server.com should be similar to the arguments you passed to ssh. Then add a simple node app

hms add my-remote my-app --start 'node .' --build 'npm install' --tag my-dock
hms list my-remote my-app

The --start argument is your start script, --build is your build script and --docks tells hms to deploy it to 1 dock.

You are now ready to deploy your service. Goto your local app folder and do

hms deploy my-remote my-app
hms ps my-remote my-app

The ps output should verify that the app is running.

Commands

All commands have the following syntax

hms [command] [remote] [service?] [options]

hms remotes

Manage and verify remotes.

  • hms remotes add [remote-name] [remote-url] to add a new remote
  • hms remotes remove [remote-name] to remove a remote
  • hms remotes to list all remotes

  • --key,-k to specify an explicit ssh key. Per default ~/.ssh/id_rsa and the ssh agent is used.

hms list [remote] [service-name?]

List services and the configuration.

hms add [remote] [service-name]

Add a new service.

  • --start,-s to specify a start script. Ie. node . to start a node service
  • --build,-b to specify a build script. Ie. npm install . to install node modules
  • --tag,-t to specify the docks tags to match when choosing where to deploy to.
  • --limit,-l to set a max limit on the number of docks to deploy to.
  • --env,-e to set env varibles. Format is `ENV_VAR=value;ENV_VAR2=value2

hms update [remote] [service-name]

Update an existing service. Accepts the same options as hms add. Note that update will not restart the service. To do this just issue a hms restart

To delete an env variable just set it to an empty string, i.e. ENV_VAR=

hms deploy [remote] [service-name]

Upload cwd as a tarball to service-name and deploy and restart it.

  • --revision to set a deploy revision tag. Defaults to git describe if you are in a git repo.

After deploying hms will tail service output and print it to stdout until you hit ctrl+c.

hms remove [remote] [service-name]

Stop and remove a service.

hms start|stop|restart [remote] [service-name]

Send a start/stop/restart signal the service. All restarts can be done gracefully by listening for SIGTERM and exiting nicely.

hms ps [remote] [service-name?]

List processes running on all docks. Omit the service name to list all processes.

  • --env to also list the environment that the processes use.

hms log [remote] [service-name?]

Tail the log of a service. Omit the service name to tail all services. hms does not save any logs so this is just the live tail of stdout/stderr and various events.

Remote services

Run the following commands on your remote server that you want to deploy to

hms terminal

Starts a "build-and-distribute" hub that you can deploy to. After you deploy to a terminal it will run the build script and distribute the build to the docks.

  • --port,-p to change the port the terminal binds to. Defaults to 10002
  • --db to set the db file

hms dock [remote]

Starts a dock that can run and manage services.

  • --id,-i to give the dock an optional id. Defaults to hostname
  • --port,-p to change the port the dock binds to. Defaults to 10002
  • --tag,-t to give this dock some tags that you can match when deploying
  • --db to set the db file
