How to use console log parser in jenkins pipeline project - jenkins-pipeline

Question

I am new to jenkins and have build a pipeline project. In one of the stage , I build a docker image and in the next stage , I execute container-structure-test on the docker image . The test cases results can be viewed in the console output.
What I want is in the build summary page , it has a link from where I can directly view the test case results in the logs and need not to go through the complete console output. Since its not junit test cases , I could not find any straight out of the box jenkins plugin.
I came across console log parser plugin but I'm not sure how to use in jenkins declarative pipeline project . I see this option in free style project under post build action but no such option is available in pipeline project.
Could someone suggest me how I can make use of this plugin in pipeline builds to address my usecase.

Answer 1

You can write out the container running log to a file, then publish this file as report.
stage('Test') {
steps {
script {
out = sh(returnStdout: true,
script: '''
docker run ......
'''
)
writeFile text: out, file: 'test.log'
publishHTML([
allowMissing: true, alwaysLinkToLastBuild: false,
includes: 'test.log', keepAll: false,
reportDir: '.', reportFiles: 'test.log',
reportName: 'HTML Report'
])
}
}
}

Here is official documentation mentioning which method you should use:
https://www.jenkins.io/doc/pipeline/steps/log-parser/
You can use it anywhere, but probably you would like to use it at the end of the pipeline in the post phase.
Example:
pipeline {
// some stages here
post {
always {
logParser ([
projectRulePath: 'path/to/rules/file/on/the/node',
parsingRulesPath: '',
showGraphs: true,
unstableOnWarning: true,
useProjectRule: true
])
}
}
}
