Hubot makes it incredibly easy to setup on a Heroku
server, by taking advantage of its Procfile support. Simply running
git push heroku master deploys the app and starts it.
When it comes to deploying to your own Linux server, given that
foreman doesn't really like background processes (see:
ddollar/foreman#65), you need to
use something like
tmux to better manage your Hubot
If you don't already have your own Hubot repository, you can easily create one. The easiest way is using the hubot generator:
npm install -g yo generator-hubot
Run the generator in a folder of your choosing:
$ mkdir myhubot $ cd myhubot $ yo hubot
Go through the steps the generator takes you, and when you're done, initialize a Git repository and push it to Github or your preferred Git server.
Go ahead and choose where you want to run your Hubot from and SSH into your instance (we used an AWS EC2 instance). Once in it, you can clone your Hubot repository, or if you prefer, create a Capistrano recipe and deploy it.
As I mentioned before, you could run
foreman start now to check that your bot
is working, but you can't leave it running in the background out-of-the-box, as
foreman is not friendly to background processes.
You can work around this by leaving
foreman itself running in a dettached tmux
$ tmux new -s hubot $ cd /path/to/hubot $ foreman start <Ctrl-b>-d
This is not the best way to do it, as the process could end unexpectedly and it won't come up again. This forces you to re-attach to the session or kill it and restart Hubot manually.
The best way is to use either a
systemd service or
monit. For a
example, check out
In our case, we use
systemd, which allows us to start it by running
sudo service hubot start. To do this, create the following service file:
; Hubot systemd service unit file ; Place in e.g. `/etc/systemd/system/hubot.service`, then ; `systemctl daemon-reload` and `service hubot start`. [Unit] Description=Hubot Requires=network.target After=network.target [Service] Type=simple WorkingDirectory=/path/to/hubot User=deployer Restart=always RestartSec=10 ExecStart=/bin/bash -a -c 'cd /path/to/hubot && source .env && /bin/hubot --adapter slack' [Install] WantedBy=multi-user.target
Finally, you can run
systemctl daemon-reload and then
sudo service hubot start. Any changes you make to the bot can be obtained
git pull origin master and then restarting the Hubot service
service hubot restart), or by using Capistrano if you wrote the deploy recipe
Hubot is a nice addition to your team, and if you use the Slack integration, you can use it for cool stuff like deploying via your CI server, or simple things like getting pictures of pugs delivered to your channel!
