Container Security with Jenkins and Aqua


With the growing adoption of Containers comes a proportional concern for security. The Aqua Microscanner is a freely available tool that can check container images for vulnerabilities. With a Jenkins plugin available, the Aqua Microscanner can easily be integrated as part of an existing CI pipeline to integrate Container security as part of the pipeline process.

In this playground, we will be setting up a simple Jenkins job to build a docker image and scan it for vulnerabilities using the Aqua Microscanner plugin. We’ll then address the vulnerabilities before re-scanning the image.



Check Jenkins is running

In a separate tab, navigate to http://<IP>:8080 and confirm Jenkins is up. You may need to login first (admin / password)

Request for the Microscanner Token

Register for a token to use the OSS microscanner here


  1. Login to Jenkins. By default, the credentials admin and password are available for use.

  2. Click Manage Jenkins.

  3. Click the Manage Plugins button.

  4. Under Available, search for microscanner.

  5. Check the install tickbox and click Download now and install after restart.

  6. Once the plugins are installed, check the restart Jenkins tickbox and wait for Jenkins to restart.

  7. Log back into Jenkins.

  8. Click Manage Jenkins.

  9. Click Configure System.

  10. Under the Microscanner subsection, put in the token obtained from registration.

  11. After clicking save, all Configurations are complete.

Building the Pipeline

Defining a freestyle microscanner job

  1. Click New Item.

  2. Select Freestyle Project and name it freestyle-microscanner.

  3. Scroll down the project Configurations and under the Build subsection, select Aqua Microscanner.

  4. Fill in the following:

    • Select Generate Report and FAIL the build
    • Type exit 1 for 'Execute shell command (optional)'
    • Select Output html report for the output format
    • Select jboss/wildfly:15.0.1.Final for the image to scan

  5. After saving the project, click build now

  6. Once the job is complete (a page refresh may be necessary), click the sphere for the console output. Note that the job is expected to fail.

  7. Click the Image name beside the Aqua Microscanner symbol.

  8. The results of the AquaMicroscanner are available across the tabs for viewing.

Defining a Pipeline script job

  1. Click New Item.

  2. Select Pipeline Script and name it ci-pipeline-microscanner.

  3. For the pipeline script, copy the pipeline script provided in the Appendix.

  4. After saving, click build now.

  5. Once again, it is expected for the job to fail. This time, instead of clicking the console output, you can try to access the artefacts from the small blue button beside the job number and click the scanout.html.

  6. The report will show that the Alpine:3.3 Image has vulnerabilities and is non-compliant.

  7. A quick fix for the image being non-compliant is to use the latest version of the alpine-image. Comment out the alpine:3.3 line and uncomment out alpine:latest.

  8. Run the build again and this time the job should succeed. You may need to refresh the page to see he last successful artifacts. Click e scanout.html to view the microscanner results.

  9. The report will show that the Alpine:latest image was compliant and why the rest of the pipeline could proceed.


In this playground, we've shown how to scan an image from the Docker repository. In addition, we've also shown how to use integrate the Aqua Microscanner into an existing pipeline to scan images before they are used.

One way to further improve and build on this playground is to use Jenkins to build a Dockerfile placed in the SCM. The Aqua Microscanner can actually be integrated as part of the Dockerfile to run its scan when building the image. More details on this process can be found in their repository.

Setting up the Playground Environment

Ensure you have the latest version of terraform installed.

Set the following environment variables:


Navigate to the _setup directory and execute:

$terraform init

Then execute:

$terraform plan

Finally, apply the plan:

$terraform apply

Tearing down the Playground Environment

Navigate to the _setup directory and execute:

$terraform destroy

Pipeline Script

pipeline {
    agent any

environment {
        DOCKER_IMAGE = 'alpine:3.3'
        // DOCKER_IMAGE = 'alpine:latest'

    stages {
                aquaMicroscanner imageName: "$DOCKER_IMAGE", notCompliesCmd: 'exit 1', onDisallowed: 'fail', outputFormat: 'html'
                echo 'Starting Jenkins checkout stage'
                echo 'Jenkins checkout stage complete'
            agent {
                docker {image "$DOCKER_IMAGE"}
                echo 'Starting Jenkins build stage' 
                echo 'Jenkins build stage complete'
                echo 'Starting Jenkins test stage'
                echo 'Jenkins test stage complete'
            steps {
                echo 'Starting Jenkins deploy stage'
                echo 'Jenkins deploy stage complete'

You can’t perform that action at this time.
