Here is the story...
i trying build a jenkins pipeline to automate a python test.
when i'm trying run 'pip install xxxx'. The jenkins built process returned pip command not found error. i notice jenkins might require python in the runtime and jenkins by default doesn't come with python.
Hence i trying to pull a docker image in pipeline.
added line "agent{ docker { image 'python:3.7.2' } }"
however docker not found error occurred during the build process
i have installed docker plugin on jenkins, but the docker error still remain...
the question is how i can make the docker work or
how i can run python in jenkins pipeline? as all i'm doing this cos i want to run python tests in jenkins pipeline.
here is the example code
pipeline {
agent{ docker { image 'python:3.7.2' } }
}
stages {
stage('checkout') {
steps{
xxxxxx
}
}
stage('setup env') {
steps {
sh 'pip install -r dependencies.txt'
}
}
stage('run test') {
steps {
sh 'pytest'
}
}
}

I am a new programmer. I have a simple calculator python code which i want to deploy using Jenkins pipeline.
There is a python unittest file in my git repo named "unit-test". I tried to execute unit test as mentioned in the stage(test), but it is not working.
stage('Test') {
steps {
echo 'Testing..'
python setup.py nosetests --with-xunit
nosetests unit-test.py
Can someone please help me fix the issue.

I have re-created your pipeline in Jenkins and it got success.
Pipeline Script
pipeline {
agent any
stages {
stage ('GIT Checkout'){
steps {
git changelog: false, poll: false, url: 'https://github.com/Tasfiq23/Devops_assessment_2.git'
}
}
stage('build') {
steps {
sh 'pip install -r requirements.txt'
}
}
stage ('Test'){
steps {
sh 'python unit-test.py'
}
}
}
}
Output:
I didn't found a solution for Windows:
This is only working for Linux:
How can I call a py script in a Jenkins File (Pipeline)?
pipeline {
agent { docker { image 'python:3.8.1' } }
stages {
stage('build') {
steps {
sh 'python --version'
}
}
}
}
As you know, the sh command let you invoke the Linux shell.
To execute your Python script on Windows, you should have the following step:
steps {
bat 'python --version'
}
currently i execute my tests in pytest by command like "pytest mytest.py" copied to inside form field "Execute Windows batch command" in the job Jenkins. I want to change my job to execute it by pipeline. I try a lot of code from Stackoverflow but any one of them doesn't work. Do you have a simple code to run regresion tests with pytest connection to Git?
I'll suggest you to use : 'Pyenv Pipeline' plugin (https://plugins.jenkins.io/pyenv-pipeline)
stage("test PythonEnv") {
withPythonEnv('python3') {
sh 'pip install pytest'
sh 'pytest mytest.py'
}
}
If you are just after running it as simple Jenkins pipeline (say scripted for now), you can run something like below?
node
{
stage('Run pytest')
{
bat "pytest mytest.py"
}
}
I am a rookie to Jenkins trying to set up a Python pytest test suite to run. In order to properly execute the test suite, I have to install several Python packages. I'm having trouble with this particular step because Jenkins consistently is unable to find virtualenv and pip:
pipeline {
parameters {
gitParameter branchFilter: 'origin/(.*)', defaultValue: 'master', name: 'BRANCH', type: 'PT_BRANCH', quickFilterEnabled: true
}
agent any
stages {
stage('Checkout source code') {
steps {
checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '------', url: 'git#github.com:path-to-my-repo/my-test-repo.git']]])
}
}
stage('Start Test Suite') {
steps {
sh script: 'PATH=/Library/Frameworks/Python.framework/Versions/3.6/bin/:$PATH'
echo "Checking out Test suite repo."
sh script: 'virtualenv venv --distribute'
sh label: 'install deps', script: '/Library/Frameworks/Python.framework/Versions/3.6/bin/pip install -r requirements.txt'
sh label: 'execute test suite, exit upon first failure', script: 'pytest --verbose -x --junit-xml reports/results.xml'
post {
always {
junit allowEmptyResults: true, testResults: 'reports/results.xml'
}
}
}
}
On the virtualenv venv --distribute step, Jenkins throws an error (I'm running this initially on a Jenkins server on my local instance, although in production it will be on an Amazon Linux 2 machine):
virtualenv venv --distribute /Users/Shared/Jenkins/Home/workspace/my-project-name#tmp/durable-5045c283/script.sh:
line 1: virtualenv: command not found
Why is this happening? The step before, I make sure to append where I know my virtualenv and pip are:
sh script: 'PATH=/Library/Frameworks/Python.framework/Versions/3.6/bin/:$PATH'
For instance, when I type in
sudo su jenkins
which pip
which virtualenv
I get the following outputs as expected:
/Library/Frameworks/Python.framework/Versions/3.6/bin/pip
/Library/Frameworks/Python.framework/Versions/3.6/bin/virtualenv
Here are the things I do know:
Jenkins runs as a user called jenkins
best practice is to create a virtual environment, activate it, and the perform my pip installations inside there
Jenkins runs sh by default, not bash (but I'm not sure if this has anything to do with my problem)
Why is Jenkins unable to find my virtualenv? What's the best practice for installing Python libraries for a Jenkins build?
Edit: I played around some more and found a working solution:
I don't know if this is the proper way to do it, but I used the following syntax:
withEnv(['PATH+EXTRA=/Library/Frameworks/Python.framework/Versions/3.6/bin/']) {
sh script: "pip install virtualenv"
// do other setup stuff
}
However, I'm now stuck w/ a new issue: I've clearly hardcoded in my Python path here. If I'm running on a remote Linux machine, am I going to have to install that specific version of Python (3.6)?
I am trying to use python image to build and test a very simple python project. But when I give Docker Image name in Jenkinsfile, it fails to pull the image.

Tried mounting the docker host using a docker-compose file

jenkins:
image: jenkinsci/blueocean
ports:
- 8888:8080
volumes:
- /var/run/docker.sock:/var/run/docker.sock
restart: always
also added user jenkins to docker group(is this correct user?)
But it still did not work. DroneIO also used docker images to setup environment but it did not have this issue.
I have encountered the same problem.
The Docker daemon inside container seems not started. I started if manually by docker exec -u root jenkins /bin/sh -c 'dockerd >/var/log/docker.log 2>&1 &'. It seems to work.
Now, i try to build a Dockerfile that exends jenkins/blueocean:latest with a modification af entry point script to start docker daemon automatically.
