I'm trying to setup the forwarder on docker (beginner to docker). I got the sample yml file from: https://hub.docker.com/r/splunk/universalforwarder/
When I try to run docker-compose up, I receive the following error:
←[31mERROR←[0m: In file '.\docker-compose.yml', service must be a mapping, not a NoneType.
Can anyone help point out the error?
My yml file:
version: '2'
services:
vsplunk_uf:
image: busybox
volumes:
- /opt/splunk/etc
- /opt/splunk/var
splunkuniversalforwarder:

hostname: splunkuniversalforwarder
environment:
SPLUNK_START_ARGS: --accept-license --answer-yes
