I want to convert the below openshift command to run from jenkins pipeline by
openshift build plugin.
oc start-build ${appName}-docker --from-file=microservicesdemoapp/target/myapp.jar -n ${project}
The problem is that I can't find how to provide the --from-file parameter via the plugin.
It would just get passed as an individual quoted argument similar to below:
openshift.startBuild("${applicationName}", "--from-dir=.", "--wait=true", "-n
${projectName}")

I have a web (online calculator for an example) which developed by my fellow tem members. Now they want to deploy in PCF using manifests.
Languages used : python, php and javascipt.
I gone through the docs about pcf with manifest.yml
In that I don't have any idea about services and env.
What is that services and how can I find the services for the above project and also how can I find the environment variables?
And tell whether these fields are mandatory to run the project in PCF.
To your original question:
What is that services and how can I find the services for the above project and also how can I find the environment variables? And tell whether these fields are mandatory to run the project in pcf.
Does your app require any services to run? Services would be things like a database or message queue. If it does not, then you do not need to specify any services in your manifest. They are optional.
Similarly, for environment variables, you would only need to set them if they are required to configure your application. Otherwise, just omit that section of your manifest.
At the end of the day, you should talk with whomever developed the application or read the documentation they produce as that's the only way to know what services or environment variables are required.
In regards to your additional questions:
1)And also I have one more query...like in our application we used python ok! In that we use lots of pacakages say pandas,numpy,scipy and so on...how can I import all the libraries into the PCF ??? Buildpacks will contain version only right?
Correct. The buildpack only includes Python itself. Your dependencies either need to be installed or vendored. To do this for Python, you need to include a requirements.txt file. The buildpack will see this and use pip to install your dependencies.
See the docs for the Python buildpack which explains this in more detail: https://docs.cloudfoundry.org/buildpacks/python/index.html#pushing_apps
2)And also tell me what will be the path for my app name if Java I can enclose jar files
For Java apps, you need to push compiled code. That means, you need to run something like mvn package or gradle assemble to build your executable JAR or WAR file. This should be a self contained file that has everything necessary to run your app, compile class files, config, and all dependent JARs.
You then run cf push -p path/to/my-app.jar (or WAR, whatever you build). The cf cli will take everything in the app and push it up to Cloud Foundry where the Java buildpack will install things like the JVM and possibly Tomcat so you app can run.
what should I do for application devloped using pyhton , JavaScript and php....
You can use multiple buildpacks. See the instructions here.
https://docs.cloudfoundry.org/buildpacks/use-multiple-buildpacks.html
In short, you can have as many buildpacks as you want. The last buildpack in the list is special because that is the buildpack which will set the start command for your application (although you can override this with cf push -c if necessary). The non-final buildpacks will run and simply install dependencies.
3) we were using postgresql how can I use this in pcf with my app
Run cf marketplace and see if there are any Postgres providers in your Marketplace. If there is one, you can just do a cf create-service <provider> <plan> <service name> and the foundation will create a database for you to use. You would then run a cf bind-service <app> <service name> to bind the service you create to your app. This will generate credentials and pass them along to your app when it starts. You app can then read the credentials out of VCAP_SERVICES and use them to make connections to the database.

I am trying to create a build and deployment pipeline in OpenShift via Jenkins. I have followed their official tutorial: https://github.com/OpenShiftDemos/openshift-cd-demo
and properly set all policies ( i am using different project names and application but the same strategy ) yet the Jenkins app deployed on cicd project cant start to build in dev project.
Error:
Error from server (Forbidden): buildconfigs.build.openshift.io buildconfig not found though the build is created and can be seen via the web console.
I am using the --from-file instead of --from-dir for binary input.
Please help if any other policies need to be set for the Jenkins service account in cicd project to "start-build" in dev project.
Yes, the Jenkins need to have access to dev project, you can use the following command to give access:
oc policy add-role-to-user edit system:serviceaccount:cicd-tools:jenkins -n example-openshift-dockerfile
cicd-tools: Project jenkins is installed in
example-openshift-dockerfile: Project that will be changed by Jenkins
I am using Azure cli. I have created app by using azure cli command. azure site create $SITENAME --location $LOCATION --hostname $HOSTNAME -s $SUBSCRIPTIONID.
Now i want to connect it with my git account using Azure CLI.
If you use the new CLI 2.0 (https://github.com/Azure/azure-cli) you should be able to use the following command:
az appservice web source-control config-local-git -g {group} -n {webapp name}
git remote add azure https://<deploy_user_name>#MyApp.scm.azurewebsites.net/MyApp.git
If this doesn't work for your scenario, please post a feature request to our repo.
If you wish to customize continious deployment, I'm afraid there is no way to use Azure CLI in this case now.
Please use Azure web-portal to do it - details are here
You can also use Visual Studio Team Services and have the compile website, and then execute your ARM template, through release management to update environment.
How can i access jenkins build status at runtime without email-ext plugin?
i want to access build_status using environment variable of jenkins. Or Any other way to access build status variable of jenkins?
The default Jenkins environment variables don't include the build result.
However, you can use the Groovy Postbuild Plugin, which is run under the Jenkins JVM and have access to the current instance of the build.
Then from groovy you can access the build result via manager.build.result. See my answer here for the example usage.
You can use currentBuild.currentResult which is a global variable inside jenkins server to access the current build status. These variables are accessible inside pipelines.
Further you can check all the available global variables inside the server using below url
http://<server>/pipeline-syntax/globals
I am setting up Jenkins to replace our current TeamCity CI build.
I have created a free-style software project so that I can execute a shell script.
The Shell script runs the mvn command.
But the build fails complaining that the 'mvn' command cannot be found.
I have figured that this is because Jenkins is running the build in a different shell, which does not have Maven on it's path.
My question is; how do I add the path so 'mvn' is found in my Shell script? I've looked around but can't spot where the right place might be.
Thanks for your time.
I solved this by exporting and setting the Path in the Jenkins Job configuration where you can enter shell commands. So I set the environments variable before I execute my Shell script, works a treat.
Some possible solutions:
You can call maven with an absolute path
You configure a global environment variable in the jenkins system settings with the absolute path to your maven instance, and use this in your script call (if you use the inline shell script, I don't know if those are substituted to a called script, you have to test)
You use a maven project and configure your maven instance in the jenkins system settings
ps.: Usually /bin/sh is chosen from Jenkins, if you want to switch to eg. bash, you can configure this in the jenkins system settings, in case you want to configure global environment variables.
You can use envInject plugin. It's very powerful.
I use it to install rbenv. And it can inject environment variables into your current job.
Another option to Dags suggestion is that if you're only using a single version of maven, on each slave server you could do either;
* add PATH=${PATH}:
* symlink mvn into /usr/bin with; sudo ln -s /usr/bin
I'm not at a Jenkins box at the moment, but I can find some more detailed examples if you'd like.
Jenkins is using sh by default and not bash.
This is my first time defining a jenkins maven job, and I also followed soem regular maven instructions (for running from command line...), and tried to update ~/.bashrc with M2_HOME, M2, PATH, but it didn't work because jenkins used sh and not bash. Then I found out that there is a simpler and better way built into jenkins.
After installing maven, I was supposed to configure my maven installation in jenkins.
To configure your maven installation in Jenkins:
login to jenkins web console
click Manage Jenkins --> Configure System
Under Maven, click the "Maven Installations..." button
a. Give it some name
b. and under MVN_HOME set the path to where you installed maven, for example "/usr/local/apache-maven/apache-maven-3.0.5"
Click Save button
Define a job with maven target
edit your job
Click "Add build step"
on Maven Version, enter the name you gave your maven installation (step #4 above)
set some goal like clean install
