3. clone repo 5c8bfce (head of the main branch)
4. docker-compose -f docker-compose.yml up -d fails to start web container with error bad URI(is not URI?): "'redis://redis/1'" (URI::InvalidURIError)

jupiter/docker-compose.demo.yml

Line 37 in 5c8bfce

- REDIS_URL='redis://redis/1'

My guess is maybe its the quotes in the yaml file?

https://github.com/ualbertalib/jupiter/blob/master/docker-compose.demo.yml#L37

Should be just - REDIS_URL=redis://redis/1

(Production docker compose which UAT uses does the same thing and its working 🤔 . Can check it's version from the .env_deployment dot file)

Edit: Ah saw your commit with this fix, once you PR is up I'll approve it 😄

[jefferya]

New versions of docker-compose, if I understand some of the reports, became subtly more strict when interpreting yaml.

Believe this can be closed now, should be fixed by #2611
