阅读更多关于 How to resolve “Cannot retrieve .Id from docker” when building Docker image using Jenkins pipeline

问题 I am using a Jenkins pipeline to build a Dockerfile. The dockerfile successfully goes through all steps, and creates the docker image. As shown: Step 16/19 : FROM base AS final ---> <id> Step 17/19 : WORKDIR /app ---> Using cache ---> <id> Step 18/19 : COPY --from=publish /app . ---> Using cache ---> <id> Step 19/19 : ENTRYPOINT ["", "myapp.dll"] ---> Using cache ---> <id> Successfully built cb3y81938e88 Successfully tagged myapp:latest However, after this, the shell Fails with the following

How do I make Jenkins 2.0 execute a sh command in the same directory as the checkout?

阅读更多关于 How do I make Jenkins 2.0 execute a sh command in the same directory as the checkout?

问题 Here's my Jenkins 2.x pipeline: node ('master'){ stage 'Checkout' checkout scm stage "Build Pex" sh('build.sh') } When I run this pipeline the checkout puts the code into to the workspace as expected, however instead of expecting to find the script in workspace/ (it's really there!), it looks in an unrelated directory: workspace@tmp/durable-d812f509. Entering stage Build Pex Proceeding [Pipeline] sh [workspace] Running shell script + build.sh /home/conmonsysdev/deployments/jenkins_ci_2016

Grouping and decorating groups of parameters in Jenkins

阅读更多关于 Grouping and decorating groups of parameters in Jenkins

问题 I'm writing a Jenkins pipeline job with quite a few parameters and I'm looking for a way to visually group them together so they will be easier to understand -rather than have them all just thrown in there. I'll settle for anything that at least hints a the fact that these parameters are related to each other. Could be a header, could be boxes. Is there any plugin that will help me decorate my inputs this way? 回答1: So, after much searching the web I finally found a plugin that does the trick.

How to execute a command in a Jenkins 2.0 Pipeline job and then return the stdout

阅读更多关于 How to execute a command in a Jenkins 2.0 Pipeline job and then return the stdout

Is there a better way to run a shell task in a Jenkins 2.0 pipeline and then return the stdout of the command. The only way I can get this to work is to pipe the output of the command to a file and then read the file in to a variable. sh('git config --get remote.origin.url > GIT_URL') def stdout = readFile('GIT_URL').trim() This seems like a really bad way to return the output. I was hoping I could do something like: def stdout = sh('git config --get remote.origin.url').stdout or def exitcode = sh('git config --get remote.origin.url').exitcode Is this possible? philbert Yes as luka5z mentioned

Jenkins pipeline (parallel && dynamically)?

阅读更多关于 Jenkins pipeline (parallel && dynamically)?

Question I have simple parallel pipeline (see code) which I use together with Jenkins 2.89.2. Additionally I use parameters and now want to be able to in-/decrease the number of deployVM A..Z stages automatically by providing the parameter before job execution. How can I dynamically build my pipeline by providing a parameter? Researched so far: Jenkins pipeline script created dynamically - Not getting this to work with my Jenkins version Can I create dynamically stages in a Jenkins pipeline? - Not working either Code The pseudo code of what I want - dynamic generation: pipeline { agent any

Complex and long single-job Jenkins Job Pipeline Builds: There yet?

阅读更多关于 Complex and long single-job Jenkins Job Pipeline Builds: There yet?

TL;DR Does it make sense to have one single Jenking Job Pipeline job for a full long-running deployment / "build" chain in the free Jenkins, given that resumable checkpoint s are not available? Prelude I'm looking at the current incarnation of Jenkins' the open/free Pipeline Bundle . I'll note that I think that what you get for free here is quite simply amazing, seeing as most of the stuff (workflow-jobs themselves, stage-view , ...) was only part of the commercial enterprise bundle of CloudBees a year or two back. Single and Multiple Jobs It also seems to me that given the stash ing abilities

Jenkins pipeline plugin: set the build description

阅读更多关于 Jenkins pipeline plugin: set the build description

问题 I'm trying to replace our current build pipeline, currently hacked together using old-school Jenkins jobs, with a new job that uses the Jenkins pipeline plugin, and loads a Jenkinsfile from the project repository. One thing that the legacy job did was set the build description to include the Mercurial hash, username and current version using the Description setter plugin, so that builds are easy to find. Is there a way to replicate/emulate this behaviour with the Jenkins pipeline plugin? 回答1:

问题 How can I teach my Jenkisfile to login via basic auth in this setup? I'm using a custom docker image for my Jenkins build. As described in the documentation here I defined a docker agent like so: pipeline { agent { docker { image 'registry.az1:5043/maven-proto' registryUrl 'https://registry.az1' args '-v /var/jenkins_home/.m2:/root/.m2' } } options { timeout(time: 1, unit: 'HOURS') buildDiscarder(logRotator(numToKeepStr:'10')) } stages { stage ('Build') { steps{ sh ... } } stage ('Test') {
