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.
Error:
................

12 passing (81ms)
+ docker build -t snapshot .
C:\WINDOWS\TEMP\jenkins6038297422360146327.sh: line 4: docker: command not found

Even after installing docker inside jenkins it is not picking my docker url
Docker inside jenkins
Complete error of 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

Jenkins Docker Problem
Hello Everyone,
I installed DockerTool on Windows7. And running Jenkins in container(http://192.168.99.100:8080), and try build image via freestyle project for a POC. Seems my Jenkins is not able to execute docker command, but getting below error on build : -
"/tmp/jenkins4044405517350577133.sh: 2: /tmp/jenkins4044405517350577133.sh: docker: not found"
I have configured, Docker as Cloud in Jenkins->Configuration, but 'Docker Host URI' as tcp://192.168.99.100:2376 is not being connected, and keep running infinitely.
This value (tcp://192.168.99.100:2376), I get from executing command (docker-machine env) for DOCKER_HOST key.
command output docker-machine env
Please help me out!!!
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 trying to run command docker-compose up -d as a build step of Jenkins, in "execute shell". Job fails and gives me following console log:
docker-compose up --build -d
Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running?
If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

When I cd into jenkins workspace (/var/lib/jenkins/workspace/app/) and tried to run docker-compose up, at first I could get a normal build. Right now I get error in console: ERROR: Error processing tar file(archive/tar: invalid tar header):. Of course app builds and runs normally in home directory when invoked from console.
Docker is running on host. It is possible to run docker-compose by regular user. I did add jenkins user to docker group. I even tried following some asian tutorial from http://blog.csdn.net/qiyueqinglian/article/details/46559825 that made me change DOCKER_OPTS in default/docker, but after restarting docker service it was not running on port 4243, so I didn't understood translation or it is not working on ubuntu 16.04 (host system).
Jenkins is not running in container, it is casually installed on host, no VM no docker, nothing. I tried removing docker and jenkins completly from host (purge etc) and reinstalling, still the same errors.
Any ideas?
Hit this command as a root user and try again
usermod -aG docker jenkins
I'm using Docker Pipeline Plugin version 1.10.
I have my Jenkins installed in a container. I have a remote server that runs a Docker daemon. The daemon is reachable from the Jenkins machine via TCP (tested). I disabled TLS security on the Docker daemon.
I'm not able to make the docker.withServer(...) step work.
As a basic test I simply put following content in a Jenkinsfile (if I'm correct this is a valid pipeline content):
docker.withServer('tcp://my.docker.host:2345') {
def myImage = docker.build('myImage')
}
When the pipeline executes I get this error: script.sh: line 2: docker: command not found like the docker command was still trying to execute locally (there is no docker command installed locally) rather than on my remote Docker daemon.
Am I missing anything ? Is it required to have the docker command installed locally when trying to execute Docker commands on a remote server..?
have you tried
withDockerServer('tcp://my.docker.host:2345') {
.....
}
Documentation here
docker needs to be installed on jenkins master in order for jenkins to be able to launch the docker on my.docker.host.
the first docker command runs on jenkins master, but with a parameter to pass the command to my.docker.host
the container itself will then run on my.docker.host
Note that you only need to install docker on the jenkins master; the daemon does not need to be running on jenkins master.
Check if you have set up port correctly. Default port for daemon is 2375. It has to be checked on both docker daemon (option -H 0.0.0.0:2375) and on the jenkins client
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?
