require('child_process').spawn;

Running a Gulpfile from a different directory is quite simple with Node's child_process#spawn module.

Try adapting the following to your needs:

// Use `spawn` to execute shell commands with Node
const { spawn } = require('child_process')
const { join } = require('path')

/*
  Set the working directory of your current process as
  the directory where the target Gulpfile exists.
*/
process.chdir(join('tasks', 'foo'))

// Gulp tasks that will be run.
const tasks = ['js:uglify', 'js:lint']

// Run the `gulp` executable
const child = spawn('gulp', tasks)

// Print output from Gulpfile
child.stdout.on('data', function(data) {
    if (data) console.log(data.toString())
})

gulp-chug

Although using gulp-chug is one way to go about this, it has been blacklisted by gulp's maintainers for being...

"execing, too complex and is just using gulp as a globber"

The official blacklist states...

"no reason for this to exist, use the require-all module or node's require"
