What's next:
Debug this container error with Gordon → docker ai "help me fix this container error"

I'm running

Client: Docker Engine - Community
Version: 29.4.2
Context: desktop-linux
Debug Mode: false

On Fedora 43

Do you know by chance if I'm doing something wrong? It seems to be a direct docker command so I'm a little lost

Thanks and regards!

[BretFisher]

i don't see an error, just some normal warnings.

[vkhemlan]

Thanks! I'm just starting in Docker but I really think it isn't running. After running the command the container does not appear when executing docker container ls

docker container run -p 4000:4000 -v $(pwd):/site bretfisher/jekyll-serve (I'm using port 80 for another service in my host)
docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

And my browser returns a 404 when trying to access localhost:4000

[BretFisher]

What are the last log entries for the container before it exited?

Adding the following requirements to the Gemfile fixed the error for me

gem "csv"
gem "base64"
gem "bigdecimal"

(I'm not fluent in Ruby to set reasonable versions for each)

Regards!
