[help wanted] Serverless says docker is not installed but it is.

[SomeNerdNamedSteve]

I am running into issues with Docker. While docker is installed, I get the error that docker not found! Please install it.. However, docker is installed. Here is my yml file:

service: image-bot

provider:
name: aws
runtime: python3.6

functions:
hello:
handler: handler.image
events:
- http:
path: /image
method: post

plugins:

• serverless-python-requirements

custom:
pythonRequirements:
dockerizePip: non-linux
`

Is there anything else I need? I have a requirements.txt file as well.

Had the same problem until I created and activated a virtualenv as described in this documentation page:

Closing this as @waylanwong has a suggested answer with no response. Will reopen if there are further issues.

For everyone coming here with this issue. The error message is misleading, the docker command execution failed and everything is munched into this single error message. In my case, the Dockerfile had an issue and wasn't building:

Error: `docker build -f Dockerfile -t sls-py-reqs-custom .` Exited with code 1`.
