I am trying to run a jenkins job inside a windows docker container. I have successfully created an image with windows server code docker image which will have MSBuildEngine 4.7.
The problem I am facing is I am not able to run a Jenkins job inside that container.
I am able to do it easily with linux environment.
The actual problem is, Jenkins first puts a shell file which will have the command to run the container and inspect it.
How do I tell Jenkins that my environment is not Linux and it is Windows.
Note: Searching in google does not help now a days. So I directly reached out here
I am working on this issue as well. I am finding that the (maybe just a) underlying issue is how Jenkins tells Docker to mount a volume to the container. I have yet to get around this issue.
edit:
There's a PR addressing this issue and I tested the fork with both Linux and Windows slaves to work as we intend.
Download Rbutcher's fork of the plugin:
git clone https://github.com/rbutcher/docker-workflow-plugin.git
Change to the working branch:
git checkout feat/windows_slaves
Build the plugin:
mvn -DskipTests clean install
Manually import into Jenkins:
Manage Jenkins> Manage Plugins> Advanced>Upload Plugin and select ./target/docker-workflow.hpi.

I want to Jenkins call a shell script from another docker container.
I don't know Jenkins can do this, and what is the best way to make it.
In one machine, I have this containers:
Service
IP (Docker network)
Note
ERP system
172.74.42.2
Odoo 14 ERP system what work with many plugin. If a plugin got new functions or fixes some bugs, need to restart the system after the pull, then update the plugin.(I write a shell script what run in ssh after push commits.
Jenkins
172.74.42.3
In here I want to call the shell script after the build is success
The Jenkins is work. So the connect between the github and jenkins is good.
I try to write shell commands in Jenkins file. But I think this is a dumb way...
I'm starting to learn Jenkins and I'm following the guide on their website. This is a new Jenkins install, installed all the recommended plugins. I've created a valid Jenkinsfile, initialized git in the project folder, and I'm trying to build, however, Jenkins doesn't seem to find Docker. When building, I get:
/Users/me/.jenkins/workspace/Test_pipeline_master#tmp/durable-ba04c9ec/script.sh: line 1: docker: command not found
Am I supposed to install a separate docker installation? I'm checking and I do have Docker plugin:
My Jenkinsfile has:
pipeline {
agent { docker { image 'node:7-alpine' } } #also tried with python:3.7 to no avail
...
What am I missing?
Yes, you need to install docker if you are planning to use docker.
Once installed, you also need to add the user 'jenkins' to docker group.
See these two links for more help.
(if you are installing jenkins on other OS, search for appropriate help for installing docker for that OS)

Background:
I am a newbie to docker.
I have 2 automation frameworks in my local PC - One for Mobile and other a web application. I have integrated the test frameworks with Jenkins.
Both test frameworks have open Jar dependencies mentioned in Maven pom.xml.
Now i want that when I click on Jenkins Job run to execute tests, my tests should run in a docker container.
Can anyone please give me steps to
Configure Docker in this completer Integrated framework
How to push my dependencies in docker
How to integrate jenkins and Docker
how to run Tests of web and mobile apps in docker on jenkins job click
I'm not a Jenkins professional, but from my experience, there are many possible setups here:
Assumptions:
By "Automation Framework", I understand that there is some java module (built by maven, I believe for gradle it will be pretty much the same) that has some tests that in turn call various APIs that should exist "remotely". It can be HTTP calls, working with selenium servers and so forth.
Currently, your Jenkins job looks like this (it doesn't really matter whether its an "old-school" job "step-by-step" definition or groovy script (pipelines):
Checkout from GIT
run mvn test
publish test results
If so, you need to prepare a docker image that will run your test suite (preferably with maven) to take advantage of surefire reports.
So you'll need to build this docker image once (see docker build command) and make it available in the private repository / docker hub depending on what your organization prefers. Technically for this docker image, you can consider a Java image as a base image, get the maven (download and unzip + configure) then issue the "git pull command". You might want to pass credentials as system variables to the docker process itself (see '-e' flag)
The main point here is that maven inside the docker image will run the build, so it will resolve the dependencies automatically (you might want to configure custom repositories if you have them in settings.xml of maven). This effectively answers the second question.
One subtle point is results that should be somehow shown in Jenkins:
You might want to share the volume with surefire-results folder with the Jenkins "host machine" so that Jenkins's plugins that are supposed to show the results of tests will work. The same idea is applicable if you're using something like allure reports, spock reports and so forth.
Now when the image is ready the integration with Jenkins might be as simple as running a docker run command and wait till it's done. So now the Jenkins job will look like:
docker run pre-defined image -e <credentials for git>
show reports
This is one example of possible integration.
One slightly different option is running docker build as a job definition. This might be beneficial if for each build that image should be significantly different but it will make the build slower.
Following approach can be followed to achieve your goal
Create a docker file with all your setup as well as dependency ( refer)
Install docker plugin on jenkins to integrate the support of docker (refer)
Use Jenkinsfile's approach to pull the docker image or create it by dockerfile and run the test within docker.
below sample code just for reference
node
{
checkout scm
docker.withRegistry('https://registry.example.com', 'credentials-id')
{
def customImage = docker.build("my-image")
docker.image('my-image').inside
{
//Run inside the container
sh 'run test'
}
}
}
How to automate Jenkins for Docker Swarm deployment.
I am wondering if there are any plugins available in Jenkins which will help in Docker Swarm deployment or any other alternative way through which we can achieve the automation of Swarm deployment using Jenkins existing plugins?
Fixed this problem by using a plugin called Publish over SSH
Need to install a Jenkins plugins “Publish over SSH”, this plugin will allows us to
Sends files over SSH(SFTP)
Execute commands on a remote server
First step will be to add remote hosts and second will be to add an execution/build step where the commands will be executed

I want to setup Jenkins master on server A and slave on server B with use of Docker.
Both servers are virtual machines dedicated for Jenkins.
Currently I have started Docker container on server A for master, based on the official Jenkins docker image. But what docker image should I use for Jenkins slave?
That actually depends on the environment and tools you need in your build environment. For example, if you build a C project, you would need an image containing a C compiler and possibly make if you use Makefiles. If you build a Java project, you would need a JDK with a Java compiler and possibly Ant / Maven / Gradle if you use them as part of your build.
You can use the evarga/jenkins-slave as a good starting point for your build slave.
This image already contains JDK. If you simply need JDK and Maven on your build slave, you can build your Docker image with the following Dockerfile:
FROM evarga/jenkins-slave
run apt-get install maven
Using Docker images for build slaves is actually a good idea. Some of the reasons appear at Templating Jenkins Build Environments with Docker Containers:
Docker has established itself as a popular and convenient way to
bootstrap isolated and reproducible environments, which enables Docker
containers to be the most maintainable slave environments. Docker
containers’ tooling and other configurations can be version controlled
in an environment definition called a Dockerfile, and Dockerfiles
allows multiple identical containers can be created quickly using this
definition or for more customized off-shoots to be created by using
that Dockerfile’s image as a base.
I suggest you take trying to use dynamic|ephemeral docker nodes, instead of manually creating nodes and connecting to them via ssh. Take a look at https://engineering.riotgames.com/news/putting-jenkins-docker-container, it's very powerful and I think it's one of killer usecases for Docker.
