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)

Can you pass a binary from a Jenkins host to an agent?
I've got Jenkins running in Kubernetes, and the terraform plugin installed on my Jenkins master with the binary located at /var/jenkins_home/tools/org.jenkinsci.plugins.terraform.TerraformInstallation/terraform/terraform
I would like to pass this to my Jenkins agent by configuring my pod template and mounting the host volume path /var/jenkins_home/tools/org.jenkinsci.plugins.terraform.TerraformInstallation/terraform/terraform to the agent's path /usr/bin/terraform
But this doesn't seem to work as expected
When I exec into the agent and run a terraform version I get the error bash: terraform: command not found indicating that it doesn't have the binary.
I can see a terraform directory mounted in /usr/bin but without the binary. What I expect is for terraform to be installed on the agent. But my thinking might be incorrect here.
Is it possible to do this, has anyone has any experience with this?
As a #David Maze mentioned binary from Jenkins needs to be manually installed on every node, which can be a difficult to manage. However you can set Jenkins to run pipeline steps inside a container where the image contains the tools you need, which simplifies such case.

One alternative is to use the slaves setup plugin. We use it to install and configure internal tools (and end) on nodes bases on labels. A log less hassle than #Malgorata's (and our previous) manually copy approach
Not sure how well it works with Kubernetes as not in our configuration.
I am trying to run a terraform command from jenkins pipeline but I am getting an error stating that, "terraform command not found". I have installed terraform plugins as well as terraform in the system where jenkins is also installed. Please help.
I haven't used Jenkins' Terraform plugin yet but have you considered to run inside a docker container which has preinstalled terraform?
I am trying to move the complete eco-system of our SAAS product to Kubernetes (and use Docker containers).
I am supposed to give a bash script which will set up everything. Only manual intervention should be setting up the Kubernetes cluster and mounting Persistent Volumes.
We were using Jenkins for code deployment and cron jobs. I am able to create the Jenkins service but I can not find ways to configure it using the command line. Tried finding ways online but can not find any good documentation.
First welcome to kubernetes, second, there are a lot of tools, templates over there, I would recommend you to check what is Helm
This is the Jenkins chart if you want to check:
https://github.com/helm/charts/tree/master/stable/jenkins
There is also a "fork" of jenkins for containerized environments, that I like, you can check more about Jenkins-X here
You can use helm package manager and simply install the Jenkin stable version.
Before using helm you have to setup tiller on kubernetes cluster.
$ helm install --name my-release stable/jenkins
here stable version of jenkin using helm.
https://github.com/helm/charts/tree/master/stable/jenkins
I can add that you can store Jenkins home folder as well as plugins and artifacts folder on persistent volume and mount that volume to Jenkins pod as a part of Helm installation. You can also make daily snapshots/backups of Jenkins disk. In this way Jenkins deployment becomes very smooth, quick and reliable.
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.
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

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
