I know there is a Nexus Platform plugin https://plugins.jenkins.io/nexus-jenkins-plugin/ in Jenkins but I am not sure if the below is possible any advise or suggestions would be appreciated.
In Jenkins you have Git choice parameter this allows you to build specific tags / branches within your job is there something similar for Sonatype Nexus? We have an internal nexus where we upload and tag docker images.
I currently have a Jenkins job I have to manually type in the image version.
Is there a way in Jenkins to get a choice parameter where i can query all the tags in nexus.
So for example I can run the command - > docker pull internal/application/service:0.0.1
So the developers would upload a new version for example 0.0.2
From Jenkins I would like to display a list of 0.0.1 or 0.0.2 for the support team to build.
Not sure if this is currently possible ?
Update 2020/07/15
I have read up on the active choice paramater plugin. This allows you to execute a groovy script.
So i created the below
import groovy.json.JsonSlurper
// GET
try {
def get = new URL("http://internalserver:8081/service/rest/v1/search?repository=docker-internal&name=application/service/moo").openConnection();
def getRC = get.getResponseCode();
//println(getRC);
if (getRC.equals(200)) {
//println(get.getInputStream().getText());
JsonSlurper slurper = new JsonSlurper()
Map parsedJson = slurper.parseText(get.getInputStream().getText())
tags = parsedJson.items.version
//println(tags)
def sorted_tags = []
sorted_tags.push(tags)
println(sorted_tags)
}
}catch(Exception e){
println(e)
}
This code does print out the tags if i run it from my IDE but if i add it to the active choice plugin my drop down menu is blank ?
Ok i got it to work Jenkins combo box requires a return type.
So if anyone ever wants to do something similar the below worked for me.
<code>
import groovy.json.JsonSlurper
try {
def get = new URL("http://yourinternalnexusurl:8018/applicacation/v1...etc").openConnection();
def getRC = get.getResponseCode();
if (getRC.equals(200)) {
def nexus_response = [:]
nexus_response = new JsonSlurper().parseText(get.getInputStream().getText())
def image_tag_list = []
for (tag in nexus_response.items.version){
image_tag_list.add(tag)
}
return image_tag_list.sort()
}
}catch(Exception e){
println(e)
}
</code>
The Maven Artifact ChoiceListProvider (Nexus) may satisfy your requirements.
With this extension its possible to use the Service API from a Maven Repositories like Nexus, Maven-Central or Artifactory to search for artifacts using groupId, artifactId and packaging.
This plugin will let the user choose a version from the available artifacts in the repository and will publish the URL as an environment variable. The Plugin will return the full URL of the choosen artifact, so that it will be available during the build, i.E. you can retrieve the artifact by using "wget"
Example
You might then have to parse (groovy ?) the resulting env variable to feed as your parameter.
Can an agent label make use of environment variable? Something like this:
pipeline {
environment {
SLAVE_NODE = 'MY_COMPUTER_NAME'
}
agent { label $SLAVE_NODE}
...
Since the editor for pipelines is so small, I would like to have the available space (visible by default) to be the "environment" block, so when I copy a jenkins job I just need to adjust a few environment variables used further in the script... I think I tried all the obvious syntax possibilities by now.
Stumbled upon it by try and error... (and found a duplicate here): Add a string parameter to your jenkins job (e.g. jenkinsNode) and use this in your script:
agent { label "${jenkinsNode}" }
I have a Microsoft Visual Studio Team Foundation Server (Version 15.117.26714.0) with predefined variable $(ProjectBuildNumber).
Is there any way to increment, during build process, value of variable with minor build number by +1?
$(ProjectBuildNumber) = 663
So, that on next build it will be:
$(ProjectBuildNumber) = 664
You can't reference variables in the build number of the Build Definition. But what you can do is override the build number in the build itself. You can either use a magic log command or use my VSTS Variables Task to set the Build.BuildNumber in the build itself. The Variables Task does expand variable references. You could probably just set the value to the current value to get it expanded.
To issue the log command yourself use a batch script, PowerShell or bash to output the following specific string to the console:
##vso[build.updatebuildnumber]build number
Update build number for current build. Example:
##vso[build.updatebuildnumber]my-new-build-number
Minimum agent version: 1.88
source: https://github.com/Microsoft/vsts-tasks/blob/master/docs/authoring/commands.md
An alternative option is to use the $(Rev) option:
Build.BuildNumber = 1.1.$(Rev:.r)
That will automatically increase the variable each time the build runs.
To update a variable in a Build Definition use yet another extension:
These things combined should be able to get what you want.
In the variable section,
set the value of ProjectBuildNumber to $[counter('', 663)].
This will queue build starting with 663 as ProjectBuildNumber and increments by 1 for the subsequent queue of builds.
Unfortunately counter function (Expressions) is not available in TFS 2018. In this old version the best solution for me is to use a PowerShell script as the first Task of the build. You can than have your parameter
$(ProjectBuildNumber)
as an input argument, and place this inline script:
$ProjectBuildNumber=$args[0]
$ProjectBuildNumber++
Write-Host "##vso[task.setvariable variable=ProjectBuildNumber;]$ProjectBuildNumber"
After this Task you can use your incremented ProjectBuildNumber variable in all subsequent Tasks.
I recently upgraded to Jenkins 2.0.
I’m trying to add a build step to a jenkins job of "Inject environment variables" along the lines of this SO post, but it’s not showing up as an option.
Is this not feature in Jenkins 2.0 (or has it always been a separate plugin)? Do I have to install another plugin, such as Envinject?
If you are using Jenkins 2.0
you can load the property file (which consists of all required Environment variables along with their corresponding values) and read all the environment variables listed there automatically and inject it into the Jenkins provided env entity.
Here is a method which performs the above stated action.
def loadProperties(path) {
properties = new Properties()
File propertiesFile = new File(path)
properties.load(propertiesFile.newDataInputStream())
Set<Object> keys = properties.keySet();
for(Object k:keys){
String key = (String)k;
String value =(String) properties.getProperty(key)
env."${key}" = "${value}"
}
}
To call this method we need to pass the path of property file as a string variable
For example, in our Jenkins file using groovy script we can call like
path = "${workspace}/pic_env_vars.properties"
loadProperties(path)
Please ask me if you have any doubt
How can I get build time stamp of the latest build from Jenkins?
I want to insert this value in the Email subject in post build actions.
Build Timestamp Plugin will be the Best Answer to get the TIMESTAMPS in the Build process.
Follow the below Simple steps to get the "BUILD_TIMESTAMP" variable enabled.
STEP 1:
Manage Jenkins -> Plugin Manager -> Installed...
Search for "Build Timestamp Plugin".
Install with or without Restart.
STEP 2:
Manage Jenkins -> Configure System.
Search for 'Build Timestamp' section, then Enable the CHECKBOX.
Select the TIMEZONE, TIME format you want to setup with..Save the Page.
USAGE:
When Configuring the Build with ANT or MAVEN,
Please declare a Global variable as,
E.G. btime=${BUILD_TIMESTAMP}
(use this in your Properties box in ANT or MAVEN Build Section)
use 'btime' in your Code to any String Variables etc..
NOTE: This changed in Jenkins 1.597, Please see here for more info regarding the migration
You should be able to view all the global environment variables that are available during the build by navigating to https://<your-jenkins>/env-vars.html.
Replace https://<your-jenkins>/ with the URL you use to get to Jenkins webpage (for example, it could be http://localhost:8080/env-vars.html).
One of the environment variables is :
BUILD_ID
The current build id, such as "2005-08-22_23-59-59" (YYYY-MM-DD_hh-mm-ss)
If you use jenkins editable email notification, you should be able to use ${ENV, var="BUILD_ID"} in the subject line of your email.
One way this can be done is using shell script in global environment section, here, I am using UNIX timestamp but you can use any shell script syntax compatible time format:
pipeline {
agent any
environment {
def BUILDVERSION = sh(script: "echo `date +%s`", returnStdout: true).trim()
}
stages {
stage("Awesome Stage") {
steps {
echo "Current build version :: $BUILDVERSION"
}
}
}
}
Try use Build Timestamp Plugin and use BUILD_TIMESTAMP variable.
Generate environment variables from script (Unix script) :
echo "BUILD_DATE=$(date +%F-%T)"
I know its late replying to this question, but I have recently found a better solution to this problem without installing any plugin. We can create a formatted version number and can then use the variable created to display the build date/time.
Steps to create: Build Environment --> Create a formatted version number:
Environment Variable Name: BUILD_DATE
Version Number Format String: ${BUILD_DATE_FORMATTED}
thats it. Just use the variable created above in the email subject line as ${ENV, var="BUILD_DATE"} and you will get the date/time of the current build.
You can use the Jenkins object to fetch the start time directly
Jenkins.getInstance().getItemByFullName(<your_job_name>).getBuildByNumber(<your_build_number>).getTime()
also answered it here:
https://stackoverflow.com/a/63074829/1968948
BUILD_ID used to provide this information but they changed it to provide the Build Number since Jenkins 1.597. Refer this for more information.
You can achieve this using the Build Time Stamp plugin as pointed out in the other answers.
However, if you are not allowed or not willing to use a plugin, follow the below method:
def BUILD_TIMESTAMP = null
withCredentials([usernamePassword(credentialsId: 'JenkinsCredentials', passwordVariable: 'JENKINS_PASSWORD', usernameVariable: 'JENKINS_USERNAME')]) {
sh(script: "curl https://${JENKINS_USERNAME}:${JENKINS_PASSWORD}#<JENKINS_URL>/job/<JOB_NAME>/lastBuild/buildTimestamp", returnStdout: true).trim();
}
println BUILD_TIMESTAMP
This might seem a bit of overkill but manages to get the job done.
The credentials for accessing your Jenkins should be added and the id needs to be passed in the withCredentials statement, in place of 'JenkinsCredentials'. Feel free to omit that step if your Jenkins doesn't use authentication.
This answer below shows another method using "regexp feature of the Description Setter Plugin" which solved my problem as I could not install new plugins on Jenkins due to permission issues:
Use build timestamp in setting build description Jenkins
If you want add a timestamp to every request from browser to jenkins server.
You can refer to the jenkins crumb issuer mechanism, and you can hack the /scripts/hudson-behavior.js add modify here. so it will transform a timestamp to server.
/**
* Puts a hidden input field to the form so that the form submission will have the crumb value
*/
appendToForm : function(form) {
// add here. ..... you code
if(this.fieldName==null) return; // noop
var div = document.createElement("div");
div.innerHTML = "<input type=hidden name='"+this.fieldName+"' value='"+this.value+"'>";
form.appendChild(div);
}
