A minimal docker image to fake the Slack API. Currently only concerned with the very minimum required to test Canvas LMS locally.
$ docker run -it -p 9393:9393 -e VIRTUAL_HOST=slack.docker ahuff44/fake-slack
Note that the VIRTUAL_HOST environment variable will let you access the service
at the host slack.docker, if you are using dinghy as part of your docker setup.
The server will log all requests it recieves to disk. The files will be placed at
/messages/slack/{{route}}_{{ts}}; e.g. /messages/slack/chat.postMessage_1563577444.405595
To use with docker-compose, here is a basic service block to start from:
slack:
image: ahuff44/fake-slack
volumes:
- "/messages/slack"
ports:
- "9393"The api is as simple as possible and returns dummy data.
Some endpoints (especially users.lookupByEmail) don't include a full
response. See the official documentation
for descriptions of what these endpoints actually return in the real slack API.
