I am trying the following on Jenkins:
steps {
script{
sshagent (credentials: ['creds']) {
sh '''
ssh -o StrictHostKeyChecking=no -tt jenkins#${IP} "
cd
"
'''
}
}
}
Obviously i am just trying to get the current directory. And as output i'm getting : [2JConnection to IP closed
Has anyone seen this before?
The issue was the -tt option, i dropped it and it worked just fine. Also, when you script windows commands like this they have to be coded in one line for some reason.

I am trying to run a gradle command inside a jenkins pipeline and for that i should cd <location> where gradle files are.
I added a cd command inside my pipeline but that is not working. I did this
stage('build & SonarQube Scan') {
withSonarQubeEnv('sonarhost') {
sh 'cd $WORKSPACE/sonarqube-scanner-gradle/gradle-basic'
sh 'echo ${PWD}'
sh 'gradle tasks --all'
sh 'gradle sonarqube --debug'
}
}
But the cd is not working, I tried dir step as suggested in pipeline docs, but i want to cd inside $WORKSPACE folder.
How can i fix this?
Jenkins resets the directory after each command. So after the first sh, it goes back to the previous location. The dir command is the correct approach, but it should be used like this:
dir('') {
}
Similar to how you have used withSonarQubeEnv
Alternatively, you can simply chain all the commands
sh 'cd $WORKSPACE/sonarqube-scanner-gradle/gradle-basic & echo ${PWD} & ...'
But this is not recommended. Since this will all be in the same command, it will run fine though.
I am trying to execute the curl command from Jenkins declarative pipeline on a remote server, however it is running on Jenkins node instead of server.
pipeline {
agent {
label
}
stages {
stage('TEst ssh') {
steps {
script {
sh '''
ssh -t user#test << ENDSSH
echo "ssh to server"
cd /opt/apps
url=$(curl -H 'X-JFrog-Art-Api: Artifactory_token' 'Artifactory_url' |jq -r '.uri')
echo $url
ENDSSH
'''
}
}
}
}
}
I am getting "Curl command not found". can anyone suggest a solution for the same?
Just put the full path to curl in the command, /bin/curl? Or change the cmd to set and check tbe path, then figure out why /bin is not in the path or if curl is even there.
Note: remote ssh login is not the same login sequence as a remote shell.
Does anybody know why:
…
steps
{
script
{
sshagent(credentials: ['jenk'])
{
sh "git remote show …" //This does not work !
bat "git remote show …" //This works ??
}
}
}
...
The 'jenk' credentials are managed via Jenkins->credentials->System->global credentials
EDIT:
Sorry forgot the error msg:
Host key verification failed
fatal: Could not read from remote repository
Jenkins was configured using CYGWIN_NT-6.3-WOW (i686 Cygwin) for the sh commands.
After all this commands cleared everything:
if (isUnix())
{
echo "Jenkins runs on Linux"
}
else
{
echo "Jenkins runs on Windows"
}
echo "show shell kernel version (uname -a) : "
def res = sh (script: "uname -a", returnStdout: true)
echo "${res}" //=>CYGWIN_NT-6.3-WOW...
res2 = sh (script: "ls -al ~/.ssh", returnStdout: true)
echo "${res2}"
So the solution to the problem above is therefore adding the ssh-keys to cygwin
If you need your credentials you could do this:

i am trying to ssh into a remote host and then execute certain commands on the remote host's shell. Following is my pipeline code.
pipeline {
agent any
environment {
// comment added
APPLICATION = 'app'
ENVIRONMENT = 'dev'
MAINTAINER_NAME = 'jenkins'
MAINTAINER_EMAIL = 'jenkins#email.com'
}
stages {
stage('clone repository') {
steps {
// cloning repo
checkout scm
}
}
stage('Build Image') {
steps {
script {
sshagent(credentials : ['jenkins-pem']) {
sh "echo pwd"
sh 'ssh -t -t ubuntu#xx.xxx.xx.xx -o StrictHostKeyChecking=no'
sh "echo pwd"
sh 'sudo -i -u root'
sh 'cd /opt/docker/web'
sh 'echo pwd'
}
}
}
}
}
}
But upon running this job it executes sh 'ssh -t -t ubuntu#xx.xxx.xx.xx -o StrictHostKeyChecking=no' successfully but it stops there and does not execute any further commands. I want to execute the commands that are written after ssh command inside the remote host's shell. any help is appreciated.
I would try something like this:
sshagent(credentials : ['jenkins-pem']) {
sh "echo pwd"
sh 'ssh -t -t ubuntu#xx.xxx.xx.xx -o StrictHostKeyChecking=no "echo pwd && sudo -i -u root && cd /opt/docker/web && echo pwd"'
}
I resolve this issue
script
{
sh """ssh -tt login#host << EOF
your command
exit
EOF"""
}
stage("DEPLOY CONTAINER"){
steps {
script {
sh """
#!/bin/bash
sudo ssh -i /path/path/keyname.pem username#serverip << EOF
sudo bash /opt/filename.sh
exit 0
<< EOF
"""
}
}
}
There is a better way to run commands on remote using SSH. I know this is late answer but I just explored this thing so would like to share and this will help others to resolve this problem easily.
I just found this link helpful on how to run multiple commands on remote using SSH. Also we can run multiple commands conditionally as mentioned in above blog.
By going through it, I found the syntax:
ssh username#hostname "command1; command2;commandN"
Now, how to run command inside remote hots using SSH in Jenkins pipeline?
Here is the solution:
pipeline {
agent any
environment {
/*
define your command in variable
*/
remoteCommands =
"""java --version;
java --version;
java --version """
}
stages {
stage('Login to remote host') {
steps {
sshagent(['ubnt-creds']) {
/*
Provide variable as argument in ssh command
*/
sh 'ssh -tt username#hostanem $remoteCommands'
}
}
}
}
}
Firstly and optionally, you can define a variable that holds all commands separated by ;(semicolon) and then pass it as parameter in command.
Another way, you can also pass your commands directly to ssh command as
sh "ssh -tt username#hostanem 'command1;command2;commandN'"
I have used it in my code and it's working great!
see the output here
Happy Learning :)
Here is my Jenkins Pipeline:
pipeline {
agent {
docker {
image 'node:6-alpine'
args '-p 3000:3000'
}
}
environment {
CI = 'true'
}
stages {
stage('Build') {
steps {
sh 'npm install'
sh 'npm build'
}
}
stage('Deliver') {
steps {
sh './jenkins/scripts/deliver.sh'
input message: 'Finished using the web site? (Click "Proceed" to continue)'
sh './jenkins/scripts/kill.sh'
}
}
stage('Deploy') {
steps {
sh './jenkins/scripts/deploy.sh'
}
}
} }
I use Docker and jenkinsci/blueocean image to run Jenkins. The first two stages are kind of standard to build a NodeJS app, the third one, however, is the part that I want to Jenkins copy new files to the server. Here is the deploy.sh files:
#!/usr/bin/env sh
set -x
scp -o StrictHostKeyChecking=no -r dist/* deviceappstore:/var/www/my_website/static/
There are two problems, first jenkinsci/blueocean does not have scp (not setup) and second, the ~/.ssh/config does not exist inside of the Jankins docker image then SCP will fail to authenticate. My solution was to build a custom image extends from jenkinsci/blueocean, setup SCP and copy config file and SSH key into it.
There are some plugins like Publish Over SSH but it seems it's not useful for Pipeline projects.
Is there any better solution? It the whole scenario right or I'm doing something wrong? I'm looking for most secure and standard solution for this problem.
OK, I think I found a good solution.
Thanks to SSH Agent plugin I can easily pass the credentials to the SCP command and copy the files to the server. Something like this:
...
stage('Deploy') {
steps {
sshagent(['my SSH']) {
echo 'this works...'
sh 'scp -o StrictHostKeyChecking=no -r dist/* my_server:/var/www/my_site/static/'
}
}
}
...
This is perfect because all the credentials are inside of Jenkins server and there's nothing about it in the repo.
And to be able to use this, there's just one solution. You need to use apk inside of the jenkinsci/blueocean (alpine) image and setup openssh:
apk add openssh
Or better solution create a new Dockerfile and build your own version.
