Manage Docker-Compose via Node.js

docker-compose is a small library that allows you to run docker-compose(which is still required) via Node.js. This is useful to bootstrap test environments. You might also generate your docker-compose.yml files using composefile.

Installation

npm install --save-dev docker-compose

Usage

docker-compose current supports these commands:

  • upAll(options) - Builds, (re)creates, starts, and attaches to containers for all services - always uses the -d flag due to non interactive mode
  • upMany(services, options) - Builds, (re)creates, starts, and attaches to containers for the services specified in services - always uses the -d flag due to non interactive mode
  • upOne(service, options) - Builds, (re)creates, starts, and attaches to containers for a service specified in service - always uses the -d flag due to non interactive mode
  • down(options) - Stops containers and removes containers, networks, volumes, and images created by up
  • kill(options) - Force stop service containers
  • stop(options) - Stop running containers without removing them
  • stopOne(service, options) - Stops one container without removing it
  • rm(options) - Remove stopped service containers - always uses the -f flag due to non interactive mode
  • exec(container, command, options) - Exec command inside container, uses -T to properly handle stdin & stdout
  • logs(services, options) - Show logs of service(s). Use options.follow true|false to turn on --follow flag.
  • run(service, command, options) - Run a one-off command on a service, uses -T to properly handle stdin & stdout
  • buildAll(options) - Build or rebuild services
  • buildMany(services, options) - Build or rebuild services
  • buildOne(service, options) - Build or rebuild service
  • pullMany(services, options) - Pull service images specified
  • pullOne(service, options) - Pull a service image
  • pullAll(options) - Pull all service images
  • restartAll(options) - Restart all services
  • restartMany(services, options) - Restart services
  • restartOne(service, options) - Restart service
  • ps(options) - Lists containers information
  • config(options) - Validates configuration files and returns configuration yaml
  • configServices(options) - Returns list of services defined in configuration files
  • configVolumes(options) - Returns list of volumes defined in configuration files

All commands return a Promise({object}) with stdout and stderr strings and an exit code:

{
  out: 'stdout contents',
  err: 'stderr contents',
  exitCode: 0, // !== 0 in case of an error
}

Example

To start service containers based on the docker-compose.yml file in your current directory, just call compose.up like this:

compose.upAll({ cwd: path.join(__dirname), log: true })
  .then(
    () => { console.log('done')},
    err => { console.log('something went wrong:', err.message)}
  );

To execute command inside a running container

compose.exec('node', 'npm install', { cwd: path.join(__dirname) })

Options

docker-compose accepts these params:

  • cwd {string}: mandatory folder path to the docker-compose.yml
  • config {(string|string[])}: custom and/or multiple yml files can be specified (relative to cwd)
  • [log] {boolean}: optional setting to enable console logging (output of docker-compose stdout/stderr output)
  • [composeOptions] string[]|Array<string|string[]: pass optional compose options like "--verbose" or [["--verbose"], ["--log-level", "DEBUG"]] or ["--verbose", ["--loglevel", "DEBUG"]] for all commands.
  • [commandOptions] string[]|Array<string|string[]: pass optional command options like "--build" or [["--build"], ["--timeout", "5"]] or ["--build", ["--timeout", "5"]] for the up command. Viable commandOptions depend on the command (up, down etc.) itself

Running the tests

While docker-compose runs on Node.js 6+, running the tests requires you to use Node.js 8 as they make use of async/await.

npm test
