Process manager for Procfile-based applications and tmux

Overview

Overmind

Release Build Status

Overmind is a process manager for Procfile-based applications and tmux. With Overmind, you can easily run several processes from your Procfile in a single terminal.

Procfile is a simple format to specify types of processes your application provides (such as web application server, background queue process, front-end builder) and commands to run those processes. It can significantly simplify process management for developers and is used by popular hosting platforms, such as Heroku and Deis. You can learn more about the Procfile format here.

There are some good Procfile-based process management tools, including foreman by David Dollar, which started it all. The problem with most of those tools is that processes you want to manage start to think they are logging their output into a file, and that can lead to all sorts of problems: severe lagging, losing or breaking colored output. Tools can also add vanity information (unneeded timestamps in logs). Overmind was created to fix those problems once and for all.

See this article for a good intro and all the juicy details! Introducing Overmind and Hivemind

Overmind features

You may know several Procfile process management tools, but Overmind has some unique, extraterrestrial powers others don't:

  • Overmind starts processes in a tmux session, so you can easily connect to any process and gain control over it;
  • Overmind can restart a single process on the fly β€” you don't need to restart the whole stack;
  • Overmind allows a specified process to die without interrupting all of the other ones;
  • Overmind can restart a specified processes automatically when they die;
  • Overmind uses tmux's control mode to capture process output β€” so it won't be clipped, delayed, and it won't break colored output;
  • Overmind can read environment variables from a file and use them as parameters so that you can configure Overmind behavior globally and/or per directory.

If a lot of those features seem like overkill for you, especially the tmux integration, you should take a look at Overmind's little sister β€” Hivemind!

Installation

Note: At the moment, Overmind supports Linux, *BSD, and macOS only.

Overmind works with tmux, so you need to install it first:

# on macOS (with homebrew)
$ brew install tmux

# on Ubuntu
$ apt-get install tmux

Note: You can find installation manual for other systems here: https://github.com/tmux/tmux

There are three ways to install Overmind:

With Homebrew (macOS)

brew install overmind

Download the latest Overmind release binary

You can download the latest release here.

Build Overmind from source

You need Go 1.12 or later to build the project.

$ GO111MODULE=on go get -u github.com/DarthSim/overmind/v2

Note: You can update Overmind the same way.

Usage

In short: You can get help by running overmind -h and overmind help [command].

Running processes

Overmind reads the list of processes you want to manage from a file named Procfile. It may look like this:

web: bin/rails server
worker: bundle exec sidekiq
assets: gulp watch

To get started, you just need to run Overmind from your working directory containing a Procfile:

$ overmind start

You can also use the short alias:

$ overmind s

Specifying a Procfile

If a Procfile isn't located in your working directory, you can specify the exact path:

$ overmind start -f path/to/your/Procfile
$ OVERMIND_PROCFILE=path/to/your/Procfile overmind start

Specifying the ports

Overmind sets environment variable PORT for each process in your Procfile so that you can do things like this:

web: bin/rails server -p $PORT

Overmind assigns the port base (5000 by default) to PORT for the first process and increases PORT by port step (100 by default) for the each next one. You can specify port base and port step like this:

$ overmind start -p 3000 -P 10
$ OVERMIND_PORT=3000 OVERMIND_PORT_STEP=10 overmind start

Disabling PORT variable

If you don't want Overmind to set PORT variable, you can disable it:

$ overmind start -N
$ OVERMIND_NO_PORT=1 overmind start

Running only the specified processes

You can specify the names of processes you want to run:

$ overmind start -l web,sidekiq
$ OVERMIND_PROCESSES=web,sidekiq overmind start

Not running the specified processes

Similar to the above, if there are some processes in the Procfile that you do not want to run:

$ overmind start -x web,sidekiq
$ OVERMIND_IGNORED_PROCESSES=web,sidekiq overmind start

This takes precedence over the previous -l flag. i.e. if you:

$ overmind start -l web -x web
$ OVERMIND_IGNORED_PROCESSES=web OVERMIND_PROCESSES=web overmind start

Nothing will start.

Scaling processes (formation)

By default, Overmind starts one instance of each process, but you can set the number of each process instances to run:

$ overmind start -m web=2,worker=5
$ OVERMIND_FORMATION=web=2,worker=5 overmind start

There is a special name all that you can use to scale all processes at once:

$ overmind start -m all=2,worker=5
$ OVERMIND_FORMATION=all=2,worker=5 overmind start

If you set instances number of some process to zero, this process won't be run:

$ overmind start -m some_production_task=0
$ OVERMIND_FORMATION=some_production_task=0 overmind start

Processes that can die

Usually, when a process dies, Overmind will interrupt all other processes. However, you can specify processes that can die without interrupting all other ones:

$ overmind start -c assets,npm_install
$ OVERMIND_CAN_DIE=assets,npm_install overmind start

Auto-restarting processes

If some of your processes tend to randomly crash, you can tell Overmind to restart them automatically when they die:

$ overmind start -r rails,webpack
$ OVERMIND_AUTO_RESTART=rails,webpack overmind start

Specifying the colors

Overmind colorizes process names with different colors. May happen that these colors don't match well with your color scheme. In this case, you can define your own colors using xterm color codes:

$ overmind start -b 123,123,125,126,127
$ OVERMIND_COLORS=123,123,125,126,127 overmind start

If you want Overmind to always use these colors, you can specify them in the environment file located in your home directory.

Connecting to a process

If you need to gain access to process input, you can connect to its tmux window:

$ overmind connect [process_name]

You can safely disconnect from the window by hitting Ctrl b and then d.

Restarting a process

You can restart a single process without restarting all the other ones:

$ overmind restart sidekiq

You can restart multiple processes the same way:

$ overmind restart sidekiq assets

It's also possible to use wildcarded process names:

$ overmind restart 'sidekiq*'

When the command is called without any arguments, it will restart all the processes.

Stopping a process

You can stop a single process without stopping all the other ones:

$ overmind stop sidekiq

You can stop multiple processes the same way:

$ overmind stop sidekiq assets

It's also possible to use wildcarded process names:

$ overmind stop 'sidekiq*'

When the command is called without any arguments, it will stop all the processes without stopping Overmind itself.

Killing processes

If something goes wrong, you can kill all running processes:

$ overmind kill

Overmind environment

If you need to set specific environment variables before running a Procfile, you can specify them in the .overmind.env file in the current working directory, your home directory, or/and in the .env file in in the current working directory. The file should contain variable=value pairs, one per line:

PATH=$PATH:/additional/path
OVERMIND_CAN_DIE=npm_install
OVERMIND_PORT=3000

For example, if you want to use a separate Procfile.dev by default on a local environment, create .overmind.env file with OVERMIND_PROCFILE=Procfile.dev. Now, Overmind uses Procfile.dev by default.

You can specify additional env file to load with OVERMIND_ENV variable:

$ OVERMIND_ENV=path/to/env overmind s

The files will be loaded in the following order:

  • ~/.overmind.env
  • ./.overmind.env
  • ./.env
  • $OVERMIND_ENV

You can also opt to skip loading the .env file entirely (.overmind.env will still be read) by setting the variable OVERMIND_SKIP_ENV.

Running a command in the Overmind environment

Since you set up an environment with .env files, you may want to run a command inside this environment. You can do this using run command:

$ overmind run yarn install

Run as a daemon

Overmind can be run as a daemon:

$ overmind start -D
$ OVERMIND_DAEMONIZE=1 overmind start

Use echo command for the logs:

$ overmind echo

You can quit daemonized Overmind with quit:

$ overmind quit

Specifying a socket

Overmind receives commands via a Unix socket. Usually, it opens a socket named .overmind.sock in a working directory, but you can specify the full path:

$ overmind start -s path/to/socket
$ OVERMIND_SOCKET=path/to/socket overmind start

All other commands support the same flag:

$ overmind connect -s path/to/socket web
$ overmind restart -s path/to/socket sidekiq
$ overmind kill -s path/to/socket

Using TCP network

Overmind can bind its command center to a TCP address instead of Unix socket. It is useful when you run it on a remote machine.

$ overmind start -s "0.0.0.0:4321" -S "tcp"
$ OVERMIND_SOCKET="0.0.0.0:4321" OVERMIND_NETWORK="tcp" overmind start

You need to pass the same flags to other commands:

$ overmind connect -s "0.0.0.0:4321" -S "tcp" web

Known issues

Overmind uses system Ruby/Node/etc instead of custom-defined one

This may happen if your Ruby/Node/etc version manager isn't configured properly. Make sure that the path to your custom binaries is included in your PATH before the system binaries path.

Overmind does not stop Docker process properly

Unfortunately, this is how Docker works. When you send SIGINT to a docker run ... process, it just detaches container and exits. You can solve this by using named containers and signal traps:

mydocker: trap 'docker stop mydocker' EXIT > /dev/null; docker run --name mydocker ...

Overmind can't start because of bind: invalid argument error

All operating systems have limitations on Unix socket path length. Try to use a shorter socket path.

Overmind exits after pg_ctl --wait start and keeps PostgreSQL server running

Since version 12.0 pg_ctl --wait start exits right after starting the server. Just use postgres command directly.

    I noticed in the error shown by overmind that it attempts to use ruby 2.3 which is not the version I'm using in my project, I use rbenv for managing my ruby environment and both the local and global version of ruby are 2.5.1

    Any ideas on what I'm missing? foreman works and running tmux new bin/rails s also works. I have really liked what overmind has to offer and that's why I decided to migrate from foreman

  • Hint to remove .overmind.sock

    Hint to remove .overmind.sock

    In some cases you can have a leftover .overmind.sock file but without a running overmind process. I think in my case this was caused by a computer restart while it was running. It would be nice if the error you get when trying to reboot overmind would prompt you to remove the file if you know that it's not currently running.

    Current message:

    overmind: listen unix /Users/joekur/dev/reverb/.overmind.sock: bind: address already in use

    As an example, zeus (https://github.com/burke/zeus) gives this message:

    Unable to accept socket connection. It looks like Zeus is already running. If not, remove .zeus.sock and try again.

    /usr/local/bin/tmux
    
    $ tmux -V
    tmux 3.1c
    
    $ overmind -v
    Overmind version 2.2.0
    

    But when I try to launch overmind s, I still get the error:

    overmind: Can't find tmux. Did you forget to install it?

  • Overmind is crashing tmux on ^C

    Overmind is crashing tmux on ^C

    If I fire up a bunch of processes, and hit ^C, overmind generally stops the underlying processes and everything is fine.

    Beginning with a recent update to tmux (v3.2a), it has started causing tmux to crash, and overmind exits with the error "overmind: Tmux client unexpectidly exited". (the mispelling here was recently fixed, thanks!)

    When I strace the processes, I see tmux is segfaulting

    [pid 1708098] --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x110} ---
    [pid 1708098] +++ killed by SIGSEGV +++
    

    This happens on both macOS and Linux machines with the latest versions of tmux. I am unable to reproduce it with versions prior to tmux 3.

    I recompiled tmux to force logging, and it looks like the tmux client dies, a new one is spawned, but it can't connect, and then everything dies.

    I think there is a race condition somewhere, and I am having trouble nailing it down - any help would be appreciated. I'll open an issue over at tmux/tmux if I can reproduce this without overmind (which I have not yet been able to do).

  • overmind weird behaviors

    overmind weird behaviors

    Hey all ! I'm sorry to bother you but since I upgraded overmind from 1.X to the last version (2.0.3). It behaves weirdly.

    First it does not log the combined output of all commands when launched with overmind start -f Procfile.dev -p 3000. Second, the restart does not really restart the commands, it is stuck indefinitely (tmux version 2.9a).

    Did I do something wrong ? Is there something I could do to help me/you debug ?

  • Allow to specify custom env file

    Allow to specify custom env file

    Basically, if one has more than one .env file, it'd be great to be able to specify which file to use (i.e. foeman's -e option). Moreover, maybe I'm wrong, but when you have more than one project the global ~/.overmind.env seems to be quite a weird solution.

  • Permission denied running with docker

    Permission denied running with docker

    Hi, I am trying to replace foreman with overmind. All my dev setup is running with Docker evilmartians/ruby-on-whales setup. To get overmind running I add some changes to my Dockerfile

    1. Add go
    COPY --from=golang:1.19.1-bullseye /usr/local/go/ /usr/local/go/
    
    ENV GOPATH=$HOME/go
    ENV PATH $PATH:/usr/local/go/bin:$GOPATH/bin
    
    1. Install tmux using apt-get
    2. Install overmind:
    RUN go install github.com/DarthSim/overmind/[email protected]
    

    This is working, but when I try to start all Processes I get Permission denied πŸ˜” shot2022-09-30 at 10 55 20@2x

    What am I doing wrong?

    Thanks

  • Apply remain-on-exit tmux option only to windows created by overmind

    Apply remain-on-exit tmux option only to windows created by overmind

    Hello :wave: thank you for creating overmind, I really appreciate this tool πŸ₯‡ I'm an avid tmux user and I usually run overmind as a daemon. I start my web server and stuff, run overmind connect and do all my work right there in that tmux session where I can have everything in one place thanks to overmind πŸ™‚

    However, I noticed the remain-on-exit tmux option being set globally using setw -g and it's making all the windows I open inherit this setting. Looks like it's possible to make remain-on-exit only apply to windows that overmind created with this simple change I made. I imagine this would save the trouble of dealing with Pane is dead messages for someone looking at some logs with overmind connect and quickly wanting to do something in the same tmux session :grin: The -p flag restricts this setting to the pane, so it'll make it possible to even do some work in a split pane in the same windows as process run by overmind.

    Thanks again and let me know if you'd be open to this change :blush:

  • Stop specific processes before terminating the rest of the processes

    Stop specific processes before terminating the rest of the processes

    So this may be a weird request, but I have a dilemma. I have an application that requires patched versions of Redis and Memcached, so at checkout the setup script builds both of them from source. Because of this, both Redis and Memcached are started with the rest of the process in the development Procfile.

    Would it be possible when Overmind receives a Ctrl+C to stop a program (in this case Rails and Sidekiq) before stopping Redis and Memcached so that the programs can store their data properly before shutdown?

    Sorry for such a weird request.
