Calling docker-compose with python subprocess ends with FileNotFoundError 'docker-compose'

Question

I am quite new to docker so I ran into some error state with my python script. It should listen for a couple of docker containers which have been started with docker-compose up using a specific yaml file.

The ignition process is working but when one container goes down another one (observing entity) should revive it with, say docker-compose start deadmodule

My setup:

• OS: Windows 10
• Docker: 2.0.0.0-win78 (28905)
• Docker Engine: 18.09.0
• Compose: 1.23.1
• Python 3.6

I am trying this:

subprocess.call('docker-compose',
                'start',
                'deadmodule')

And I tried it also with Popen(['docker-compose', 'start', 'deadmodule'], stdout=PIPE, stderr=PIPE)

However it ends with this:

FileNotFoundError: [Errno 2] No such file or directory: 'docker-compose': 'docker-compose'

Answer 1

当您不使用shell=True ，不会自动添加文件结尾，因此您需要调用的是docker-compose.exe ，而不是docker-compose.exe docker-compose 。
