Problem with report template "@contrib/html.tpl"

[Joerg-L]

Question

We are using Azure DevOps Pipelines, based on ubuntu-latest, to build a docker image which we want to scan.

In the Pipeline trivy release 0.52.0 is getting installed by apt-get as documented here .

Following the documentation we are trying to scan our docker image with trivy image --format template --template "@contrib/html.tpl" -o report.html svc.0000.sample:1.49.0.

Then scan fails with
FATAL Fatal error report error: unable to write results: failed to initialize template writer: error retrieving template from path: open contrib/html.tpl: no such file or directory

What do I miss?
Thanks for Helping

Hello @Joerg-L
Thanks for your interest to Trivy!

apt-get installation doesn't include contrib folder.
You need to download html.tpl file (e.g. wget https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/html.tpl) and use --template @<path/to/template>/html.tpl flag.

Regards, Dmitriy

Thanks @DmitriyLewen that is working and it would be great if that would be also mentioned in the documentation.

When UI'm no using
trivy image --format template --template "@/home/vsts/work/1/a/trivy_templates/html.tpl" -o report.html svc.0000.sample:0.0.0
it works.

But I also want to get thet "report.html" into the folder /home/vsts/work/1/a/trivy_output but when I use trivy image --format template --template "@/home/vsts/work/1/a/trivy_templates/html.tpl" -o "/home/vsts/work/1/a/trivy_output/report.html" svc.0000.sample:0.0.0 I receive

FATAL Fatal error report error: unable to write results: failed to create a file: failed to create output file: open /home/vsts/work/1/a/trivy_output/report.html: no such file or directory

I have also tryied to use

• trivy image --format template --template "@/home/vsts/work/1/a/trivy_templates/html.tpl" -o "@/home/vsts/work/1/a/trivy_output/report.html" svc.0000.sample:0.0.0
• trivy image --format template --template "@/home/vsts/work/1/a/trivy_templates/html.tpl" -o /home/vsts/work/1/a/trivy_output/report.html svc.0000.sample:0.0.0

Any idea on that?

that is working and it would be great if that would be also mentioned in the documentation.

Docs contain info about this - https://aquasecurity.github.io/trivy/v0.52/docs/configuration/reporting/#load-templates-from-a-file

FATAL Fatal error report error: unable to write results: failed to create a file: failed to create output file: open /home/vsts/work/1/a/trivy_output/report.html: no such file or directory

This happens because one of directory from output path doesn't exist (trivy_output in your case).
Trivy doesn't create directories. Trivy only creates output file.

@knqyf263 Perhaps we want to fix this - create the required directories?

[knqyf263]

The error message, no such file or directory, is well described. I don't think Trivy need to create a dir.

@DmitriyLewen @knqyf263

I don't think Trivy need to create a dir.

I guess it depends, many other tools does it for more useability and convinience.
But sure, it is not main task of trivy to create an directory.

Thanks for your help

We're open to the change if many users hope.
