Monitoring remote docker instances using watchtower

[droidus]

I am using watchtower to update remote docker instances. I am using the docker-compose.yml file to stand up the watchtower instance. I have my environment variable defined, and set my DOCKER_HOST to “tcp://1.2.3.4:2375 1.2.3.5:2375”. I am getting this error message though: time=“2023-06-08T22:02:25Z” level=fatal msg=“Error instantiating Docker client: parse "tcp://x:2375, tcp://y:2375": invalid character " " in host name”. How can I define multiple instances for watchtower to monitor and report on?
