Unable to run docker in Interactive mode

General Discussions

I was trying to run docker in interactive mode where i could login to the container.

I switched to root user then I pulled the image using: docker pull jenkinsci/blueocean
This was successful.

I then tried running this image container in interactive mode using:

docker run -ti -p 8080:8080 -p 50000:50000 -v /tmp:/tmp jenkins

This starts the jenkins container but does not give me the containers prompt / shell

These are the last lines that i see as output and this is where it stays:

INFO: Obtained the updated data file for hudson.tools.JDKInstaller

Oct 12, 2018 3:52:58 AM hudson.model.AsyncPeriodicWork$1 run

INFO: Finished Download metadata. 4,930 ms

–> setting agent port for jnlp

Here is my docker version:

Can you please suggest how can i get into the docker container’s prompt ?

Note: I m setting up docker container on Linux Virtual Cloud based server.

Hi,

you could give it a try with first starting a shell in interactive mode and then start jenkins when you’re attached to the shell like this:

`docker run -ti -p 8080:8080 -p 50000:50000 -v /tmp:/tmp bash
then when your’re attached to the bash inside the container call the jenkins command.

Hope this helps.
