To get approval of continuous integration continuous delivery/deployment (CICD) by the Akraino committee. i.e., By pushing the logs to Nexus Akraino Repository.

Who should push the logs? / Where should the logs be pushed?

• who/from: private-lab's setup Jenkins Jenkins setup in a lab (private/shared lab)
• where/to: Nexus Repository Manager - Akraino

...

Access to Nexus Akraino Repository. (How to get access of Nexus Akraino Repository?)

...

Jenkins for private lab:

...

• setup Jenkins locally
• push logs to Nexus Akraino Repository

Note: In this guide, we use docker container for Jenkins installation. 

...

Setup Jenkins locally: 

• Create a local directory on host-machine, where you want to store the container-logs:

  Code Block
  title Setup Volume for Jenkins container on Host-machine
  mkdir /jenkins sudo chown -R 1000:1000 /jenkins/

  
  

• Install/setup Jenkins using the command:

  Code Block
  docker run --name JENKINS-CONTAINER-NAME --rm --detach --privileged --network jenkins --network-alias docker --volume /jenkins:/var/jenkins_home --publish 2376:2376 -p 80:8080 -p 50000:50000 mehmoodasif/jenkins

  
  

Setup credentials to access Nexus Akraino Repository: 

• Create an a .netrc file as follows:

  Code Block
  title .netrc file
  machine nexus.akraino.org login LFID_USERID password LFID_PASSWORD

  
  

• Copy the .netrc file to /jenkins/ directory of host-machine. 

Push logs to Nexus Akraino Repository:

To push the logs using, you'll have to:

• write a script to push logs
• create/configure a job on your jenkins
• validate that the CICD logs on Nexus Akraino Repository

Write a script to push logs: 

Create an .sh file. We named it as push-logs.

...

sh:

NEXUS_URL=https://nexus.akraino.org
SILO=<silo name provided above>
JENKINS_HOSTNAME=<hostname/IP of your Jenkins host>

# JOB_NAME and BUILD_NUMBER should be set by Jenkins 
BUILD_URL="${JENKINS_HOSTNAME}/job/${JOB_NAME}/${BUILD_NUMBER}/"

NEXUS_PATH="${SILO}/job/${JOB_NAME}/${BUILD_NUMBER}"

lftools deploy logs $NEXUS_URL $NEXUS_PATH $BUILD_URL
 
echo "Logs uploaded to $NEXUS_URL/content/sites/logs/$NEXUS_PATH"

Create/configure a job on your Jenkins: 

...

Follow these steps:

• Log into to Jenkins
• Through the Dashboard, go to New Item
• Enter an item name (in our case, we used push-logs)
• Select the Pipeline options shown
• Click OK

• In the General (tab), under the Pipeline section, Pipeline script option must be selected. And paste the below provided groovy script into the Script area. The script is as follows:
  Below line change-directory to where your script exists.

  Code Block
  language groovy title An example (groovy-script) to push logs to Nexus Akraino Repository linenumbers true
  pipeline { agent none stages { stage ("push-logs-nexus") { agent any steps { sh "echo 'Start of job (push-logs)'" sh "pwd" dir("../scripts/") { sh "pwd" sh "./push-logs.sh" } sh "pwd" sh "echo 'End of job (push-logs)'" } } } }

  
  

• Now you have to configure the job to load/run the script to push logs (wrote in the previous step). An example on how to is provided below:

Validate that the CICD logs on Nexus Akraino Repository:

Visit the associated repository to your blueprint. The logs must be there. In our case, the link is:

• https://nexus.akraino.org/content/sites/logs/jejunu-pred-vanet-mec/job/push-logs, in which:
  • jejunu-pred-vanet-mec is your blueprint's nexus repository
  • push-logs is your job name created on Jenkins
