My IT department has blocked internet access to all but a few sites and they don't want to keep adding new sites to the proxy. Consequently, during the installation of Jenkins on linux, none of the plugins were added. Is there a way to download all the plugins and install them manually? There are too many to download and install them individually.
The best solution would be if I could re-install Jenkins without needing to connect to the internet at all.

Good afternoon,
As I understand Jenkins, if I need to install a plugin, it goes to Jenkins Plugins
The problem I have is Jenkins is installed on a closed network, it cannot access the internet. Is there a way I can download all of the plugins, place them on a web server on my local LAN, and have Jenkins reach out and download plugins as necessary? I could download everything and install one plugin at a time, but that seems a little tedious.
You could follow some or all of the instructions for setting up an artifactory mirror for the plugin repo.
It will need to be a http/https server and you will find that many plugins have a multitude of dependencies
The closed network problem:
You can take a cue from the Jenkins Docker install-plugins.sh approach ...
This script takes as input a list of plugins, and optionally versions (eg: $0 workflow-aggregator:2.6 pipeline-maven:3.6.5 job-dsl:1.70) and will download all the plugins and dependencies into a working directory.
Our approach is to create a file (under version control) and redirect that to the command line input (ie: install-plugins.sh $(< plugins.lst).
You can download from where you do have internet access and then place on your network, manually copying them to your ${JENKINS_HOME}/plugins directory and restart the instance.
The tedious list problem:
If you only specify top-level plugins (ie: what you need), every time you run the script, it will resolve the latest dependencies. Makes for a short list, but random dependencies if they get updated at https://updates.jenkins.io. You can use a two-step approach to address this. Use the short-list to download the required plugins and dependencies. Store the generated explicit list for future reference or repeatability.
Installed Jenkins on a Linux server and want to install some plugins manually.
I want to install Blue Ocean and Artifactory.
For both plugins I downloaded the hpi file and tried to install it, but I get a lot of dependency errors.
Do I now have to install those dependencies manually as well? or is there a better way to do this?
I tried to install one of those dependency and that one also had some dependency errors as well :-(
The Linux server is not able to access the internet.
Thanks!
Robert
You are correct that BlueOcean has a lot of dependencies.
Given you are not able to connect to the internet you will need to download all 21 BlueOcean related hpi files and upload them from the Manage Jenkins > Manage Plugins > Advanced tab.
Alternatively, if you have access to the server that your Jenkins instance is running on you can copy the hpi files into the %JENKINS_HOME%/plugins folder. The corresponding directories (exploded from the hpi, which is just a zip file) will be created on Jenkins restart.
The easiest way to acquire all 21 plugin files is to open The Jenkins plugin page and search for blueocean. Download the same numbered version of all 21 and upload them one by one. Order shouldn't be an issue. As long as they are all present on restart the dependencies will resolve.
Same process goes for any other plugin. If you're able to get the machine connected to the internet it will make the process a lot simpler as you will be able to use the update center, which manages dependencies and update notifications.
Same case here. Our Jenkins is setup in OpenShift which is not allowed to connect to the Internet. Downloading a plugin 1-by-1 is tiresome. Not to mention that each plugins have its own dependencies that needs to be downloaded as well.
Here's what you would do...
Run a Jenkins locally in a machine that can download plugins.
Download and update all the plugins you want using the Update Center.
Go %JENKINS_HOME%/plugins directory. Inside this folder you would see *.jpi. These are your plugins. Its dependencies will be downloaded as well.
Rename it to *.hpi then keep it in some directory.
To test...
In your local Jenkins delete everything in %JENKINS_HOME%/plugins directory then put all *.hpi in this directory.
Restart your local Jenkins.
Verify if the plugins you require are installed and updated.
I have a machine with blocked outgoing connections so it is not possible to update jenkins nor install the plugins I need for my work.
My idea is the following: I download the jenkins .war on my personal laptop and complete the installation + the plugin download.
Then I just move this .war to the machine where I need jenkins to be up and running.
Is it possible? Where are the plugins/updated data stored?
Also, would it be a problem the fact that my laptop has windows as os, while the destination machine is a linux RHEL?
Your solution sounds crazy :D
This could be help you:
Update Jenkins war
If you have shell access with root privilege, there is a manual way.
Download latest war file inside your linux, using wget , curl or just upload it using winscp from your windows.
Stop jenkins
Backup EVERYTHING: linux snapshot, jenkins workspace, jenkins war file, etc
Replace the old war with new war
Start jenkins

Plugin
Jenkins has an option to install plugins called Manage Plugins
This offer two options :
(1) Install plugins using available option
For official and compatible plugins, suggested by Jenkins :
(2) Install plugins using upload option
For custom plugins or when is not available on official repositories:
I could successfully install the jenkins online over my laptop. But while trying to install the jenkins offline (on my office workstation which cannot be connected to internet) the hell breaks loose.
After running the jenkins.war over command line although the jenkins was successfully installed yet some of the plugins were missing.I managed to get some help from the post How to install a plugin in Jenkins manually?
But then each of the plugins have to be individually downloaded and then copied over to my offline machine. So I had a trick.
I copied all the folders under .jenkins directory (in my online installation machine) and then copied them to my offline machine. Whoa!
It worked!
But I still get one single error:
Maven Integration Plugin V2.16 .javadoc 1.0 is missing. To fix, install v1.0 or later
So is there a way/website/pdf/repository which is a one stop solution/steps to smoothly install (read has all the required dependencies as a zip) Jenkins in offline mode. (If not, to the creators of Jenkins: Would it be a good idea to have one?)
I'm also searching for an easy way to manage the dependencies between the plugins but as far as I know there is no official tool for that.
Either you have a .zip file with all the plugins which you prepare one time or you fix the errors manually.
For your problem it should be enough to install the following .hpi file: https://updates.jenkins-ci.org/latest/javadoc.hpi (javadoc has no dependencies to other plugins)
You can download the .hpi version of plugins required and paste them in plugins folder at jenkins_home and then restart the jenkins,then you can able to use those plugins.
I have Jenkins running on a Cloudbees Fedora 17 node. I need my job to be able to install certain packages to build my project correctly for deployment but my yum install commands fail because the jenkins user does not have the correct permissions.
I cannot SSH into the box or use the jenkins CLI to assign root permissions to use sudo and Cloudbees doesn't appear to enable the Script Console. Neither can I run the yum command as with su because it expects the administrator password which I cannot enter remotely.
What can I do?
I am not aware that you can install additional software on the CloudBees Jenkins master node. But you can request from CloudBees support that additional software packages will be installed on the automatically created CloudBees build nodes.
As alternative you can also create your own build nodes (called OPE in CloudBees). This is helpful for a lot of cases such as specific software requirements (such as closed source software which requires a license) or just to be much more flexible when it comes to require packages installed on it.
Since you didn't mention what kind of packages are missing: There are a lot of frameworks that provide much more ruby, java, python, go etc. versions as any Linux distribution. CloudBees provides documentation for a lot of them on http://dev-at-cloud-docs.cloudbees.com/docs/dev-at-cloud-docs-1.1/Build+Tools.html
This is the problem with hosted solutions like what Cloudbees offers. If you need access to operating system level permissions on the host server, then you have little choice but to host Jenkins yourself, or to obtain a different licensing structure with CloudBees in order to have a VPS, or some other isolated but still SaaS hosted solution.
