I can't access Jenkins at http://localhost:8080 with Docker on MacOS - docker

Question

I typed docker pull jenkins/jenkins:lts-jdk11 to get a Jenkins image on Docker Desktop on MacOS and ran it.
Here are the logs :
user#MacBook-Pro ~ % docker pull jenkins/jenkins:lts-jdk11

I'm not dreaming. I see "Jenkins is fully up and running" at the very end of the logs but when I type http://localhost:8080/ in Chrome I end up on a page "This site can't be reached".
Anyone knows why I can't use Jenkins anymore ? It used to work before... It sucks. At the beginning, I had removed the image to download it again because I've got problems with the Cmake plugin and now absolutely nothing works. I'm gonna go bonkers.

Answer 1

please Expose the port while you are running the image
This command to deploy any docker image with exposing ports
docker run -p hostport:portinContainer imagetag
In your case
docker run -p 8080:8080 docker.io/jenkins/jenkins:lts-jdk11
( or c1ae8e3564e4)
you can also use Docker compose, Kubernetes Deployment/Service etc to deploy too and going further in journey just docker run will not help need to adapt a deployment method
Hope this v
