🐳 Complete Docker CIS Benchmark 📝

In the previous release, we have introduced Docker CIS Benchmark scanning to Trivy (trivy image --compliance docker-cis). With this release, Trivy now completes the report by detecting vulnerabilities of installed packages (section 4.4) and secrets in the Dockerfile (section 4.10).

$ trivy image --compliance docker-cis my-image

⎈ Kubernetes resources for deprecated and removal APIs 💀

When Trivy scans Kubernetes resources it can now alert when the resource is using a deprecated (or about to be) API, and will also suggest the recommended newer version. now can easily check resources against specific k8s version

trivy config ~/data/input.json  --k8s-version=1.22.0

🐭 Dependency tree and license support for Go 🌲

When scanning a Go project, Trivy now identifies dependency relationships and licenses. This works by finding package sources in $GOPATH so in order to work, make sure modules were downloaded to local cache beforehand (go mod download/go mod tidy).

$ trivy fs --scanners vuln --dependency-tree ./go.mod
2023-02-28T13:50:25.836+0200    INFO    "--dependency-tree" only shows the dependents of vulnerable packages. Note that it is the reverse of the usual dependency tree, which shows the packages that depend on the vulnerable package. It supports limited package managers. Please see the document for the detail.

🧭 Command completion

$ trivy completion zsh -h
Generate the autocompletion script for the zsh shell.

If shell completion is not already enabled in your environment you will need
to enable it.  You can execute the following once:

    echo "autoload -U compinit; compinit" >> ~/.zshrc

To load completions in your current shell session:

    source <(trivy completion zsh); compdef _trivy trivy

To load completions for every new session, execute once:

#### Linux:

    trivy completion zsh > "${fpath[1]}/_trivy"

#### macOS:

    trivy completion zsh > $(brew --prefix)/share/zsh/site-functions/_trivy

You will need to start a new shell for this setup to take effect.

See the documentation for detail.

🕐 Fail on EOSL OS 🚫

OS vendors might stop providing security advisories for operating systems after the end of support period (EOL). Thus when scanning such EOL images, newly disclosed vulnerabilities may not be detected and the scan would seemingly "succeed". The new --exit-on-eol flag enables you to "fail" the scan in such cases, so that you're at least aware of the situation.

$ trivy image --exit-on-eol 1 alpine:3.10

🫖 Configure the Java DB repository

In the previous release we introduced new Java scanning architecture that does not rely on external API calls during scan and thus is much more reliable. The new Java scanner uses a dedicated "Trivy Java DB" that is added to the regular "Trivy DB" for Java scanning. This release makes is possible override the default Java DB location using a new flag: --java-db-repository.

🎨 Input schemas for rego checks

When authoring rego checks, It's now possible to supply validate the "input" to the policy with a json schema. This is helpful to avoid typo mistakes which might lead to inaccurate detections. You can choose from the builtin schemas for Cloud, Kubernetes, and Dockerfile inputs, or provide your own json schema to validate against.
