When I was trying to run a Jenkins pipeline project, it failed giving this message under the "docker pull node:6-alpine":
<.jenkins/workspace/simple-node-js-react-npm-app#tmp/durable-431710c5/script.sh: line 2: docker: command not found
script returned exit code 127>
I have no idea what's going on here, and I couldn't access the directory mentioned in the error. I am pretty new to Jenkins.
As mentioned here, using the JENKINS Docker Plugin or JENKINS Docker Pipeline Plugin would not be enough to allow a node to use docker.
You still need to install docker on the node itself.
Please follow below steps:
Install the docker engine (yum install docker) on server where Jenkins is running.
Verify docker is installed: run command which docker.
Click on Jenkins manage plugin and install docker plugin.

I am running jenkins and docker on Ubuntu server 18.04.2 LTS and when starting
jenkins pipeline to run docker commands, I have this error:
Sorry, home directories outside of /home are not currently supported.
See https://forum.snapcraft.io/t/11209 for details.
script returned exit code 1
Can anyone help me ? Thank you
I had the same issue, I fixed it by just adding "sudo" in front of the docker command
I am trying to configure jenkins slave as docker container, have enabled docker API and connections works fine to the API
Have added the configuration for docker template and docker cloud but it seems that my job does not starts
I can see container getting created on my docker node but the job does not start
Docker cloud configuration image
docker template image
One thing to note is that when i run the container specifically on the docker node and then try to ssh using the same credentials that i am using in jenkins i can ssh into the container.
This message of "Jenkins doesn't have label XXXX" is rather misleading and unhelpful.
You think the problem is something you did wrong in your configuration and when you find out what happen it is nothing to do with jenkins or how you set up the docker plugin.
I run into the same problem than you, and the problem was the docker installation I was using.
The steps I followed to fix it were:
(I was using CENTOS7,jenkins 2.1.38, docker version 1.13.1)
1) Go to the logs of your jenkins (centos logs are /var/log/jenkins.log)
2) Looking into the logs you are going to find out the problem. For instance for me was this:
com.github.dockerjava.api.exception.NotFoundException: {"message":"driver failed programming external connectivity on endpoint happy_heyrovsky (cbfa0d43f8c89d2531323249468503be11e9dd603597a870530d28540c662695): exec: \"docker-proxy\": executable file not found in $PATH"}
As you see the problem is that docker it is not able to find docker-proxy ¿how to fix this?
Go to /usr/libexec/docker and you will see docker-proxy-current. so what you have to do is create a link:
sudo ln -s docker-proxy-current docker-proxy
Tha´s all. After doing this change I execute my build on jenkins and it works.
I've got a jenkins declarative pipeline build that runs gradle and uses a gradle plugin to create a docker image. I'm also using a dockerfile agent directive, so the entire thing runs inside a docker container. This was working great with jenkins itself installed in docker (I know, that's a lot of docker). I had jenkins installed in a docker container on docker for mac, with -v /var/run/docker.sock:/var/run/docker.sock (DooD) per https://jpetazzo.github.io/2015/09/03/do-not-use-docker-in-docker-for-ci/. With this setup, the pipeline docker agent ran fine, and the docker build command within the pipeline docker agent ran fine as well. I assumed jenkins also mounted the docker socket on its inner docker container.
Now I'm trying to run this on jenkins installed on an ec2 instance with docker installed properly. The jenkins user has the docker group as its primary group. The jenkins user is able to run "docker run hello-world" successfully. My pipeline build starts the docker agent container (based on the gradle image with various things added) but when gradle attempts to run the docker build command, I get the following:
* What went wrong:
Execution failed for task ':docker'.
> Docker execution failed
Command line [docker build -t config-server:latest /var/lib/****/workspace/nfig-server_feature_****-HRUNPR3ZFDVG23XNVY6SFE4P36MRY2PZAHVTIOZE2CO5EVMTGCGA/build/docker] returned:
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
Is it possible to build docker images inside a docker agent using declarative pipeline?
Yes, it is.
The problem is not with Jenkins' declarative pipeline, but how you're setting up and running things.
From the error above, looks like there's a missing permission which needs to be granted.
Maybe if you share what your configuration looks like and how your're running things, more people can help.
I want to create a automatic docker image through Jenkins once build got success.
I tried by providing docker commands in execute shell but throwing command not found error.If this is not right way how to achieve this in Windows 10.

Even after installing docker inside jenkins it is not picking my docker url

Created a new vm with TLS false:
docker-machine create -d virtualbox --engine-opt tlsverify=false node2
to check TLS is made false i ran below command
docker-machine env node2
here DOCKER_TLS_VERIFY = "1",however in the documentation it is mentioned DOCKER_TLS_VERIFY = "0" should be zero whether my machine now TLS enabled or not how can i confirm my machine is TLS false??
The shell you configured in your Jenkins job is executed by Jenkins executor on Jenkins machine(or Jenkins Slave machine if you're using Jenkins the Master-Slave way), so whatever command you would like to use, it must be installed correctly and in the PATH of the target machine, just like you execute command on terminal manually.
So the error message is self-explained now:
C:\WINDOWS\TEMP\jenkins6038297422360146327.sh: line 4: docker: command not found
which means you have not installed docker on your Jenkins machine, you need to install and configure it firstly.
Additionally, you may want to have a look at Docker build step plugin for Jenkins.
install docker on jenkins. Jenkins does not know about docker.
If you don't need to run Docker on the same server than Jenkins I found that downloading a Docker Client was better than using the Jenkins Plugin.
You can find the latest version here: https://download.docker.com/win/static/stable/x86_64/
Then just call the docker command with --host 192.168.99.100. It should work and build the image on the Docker Server 192.168.99.100
I want to run a docker image create command from a Jenkins job which is running native on my machine with VM running Docker.
I've installed docker build step plugin and in manage Jenkins page command fails when I try to configure docker using url and version, it says:
Test Connection Something went wrong, cannot connect to
http://192.168.99.100:2376, cause: null
I've got this docker url from the docker-machine env command.
In the version field, I tried both REST API version and Docker version, but no success.
Is it possible to call Docker from outside the docker VM and from a Jenkins job? If yes how to configure it in Jenkins?
