KeyError: 'PATH' when running docker-compose up from Fabric

I was trying to run docker-compose using Fabric, but when I run the docker-compose up command using Fabric I got the following error:

[52577] Failed to execute script docker-compose
Traceback (most recent call last):

Failed to up the env

When I run docker-compose up from the terminal it works fine.

@task
def up(c):
    if c.run('docker-compose up', warn=True).failed:
        print ("Failed to up the env")

As my comment suggested, it seems docker-composer up when it needs to do a build at least, needs the PATH environment variable to be set. To fix, I just forwarded the PATH from the current session to the child process (in PHP sorry!):

$compose = new Process( 'docker-compose up -d', '', [
    'VOLUME' => getcwd(),
    'PATH' => getenv( 'PATH' ),
] );
