如何使用docker正确设置jenkins？

Question

I'm new to Docker and am learning how to implement Docker with Jenkins. I was able to succesfully bind a docker volume to my host machine directory with the following command

docker run –name jenkinsci -p 8080:8080 -p 50000:50000 -v ~/Jenkins:/var/jenkins_home/ jenkins/jenkins:lts

Now that the basic Jenkins is set up and binded to my host, there are a few things I wasn't sure to handle.

(1) This is only accessible through localhost:8080. How do I make this accessible to other computers? I've read that I can change the URL to my company's public IP address? Is this the right approach?

(2) I want to automate the installation of select plugins and setting the paths in the Global Tools Configuration. There were some tips on github https://github.com/jenkinsci/docker/blob/master/README.md but I wasn't clear on where this Dockerfile is placed. For example, if I wanted the plugins MSBuild and Green Balls to be installed, what would that look like?

FROM jenkins/jenkins:lts
COPY plugins.txt /usr/share/jenkins/ref/plugins.txt
RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/plugins.txt

Would I have to create a text file called plugins.txt where it contains a list of plugins I want downloaded? Where will this Dockerfile be stored?

(3) I also want a Dockerfile that installs all the dependencies to run my .NET Windows project (nuget, msbuild, wix, nunit, etc). I believe this Dockerfile will be placed in my git repository.

Basically, I'm getting overwhelmed with all this Docker information and am trying to piece together how Docker interacts with Jenkins. I would appreciate any advice and guidance on these problems.

Answer 1

Its ok to get overwhelmed by docker+kubernetes. Its a lot of information and whole overall shift how we have been handling applications/services.

1. To make jenkins available on all interfaces, use following command.

docker run –name jenkinsci -p "0.0.0.0:8080:8080" -p "0.0.0.0:50000:50000" -v ~/Jenkins:/var/jenkins_home/ jenkins/jenkins:lts

2. Yes, you have to provide the plugins.txt file, and create a new jenkins image containing all the required plugins. After that you can use this new image instead of jenkins/jenkins:lts.
3. The new image, suited for your workload should contain all the dependencies required for your environment.
