hadolint VS trivy

One such linter is hadolint. It parses a Dockerfile and shows a warning for any errors that do not match its best practice rules.

Like hadolint: Dockerfile linter, validate inline bash, written in Haskell; Purescript, Unison, Idris languages implemented in Haskell. I recommend to check ideas behinds those projects. Especially Unison's mind-blowing something naive idea about infinite computational resources.

3. Hadolint: https://github.com/hadolint/hadolint Hadolint is a Dockerfile linter that helps you build best practice Docker images, reducing vulnerabilities in your container configurations.

To skip the "move your scripts to standalone files" step some devs don't like, consider something like https://github.com/hadolint/hadolint which runs Shellcheck over inline scripts within Containerfiles.

This is neat :)

I love going and making containers smaller and faster to build.

I don't know if it's useful for alpine, but adding a --mount=type=cache argument to the RUN command that `apk add`s might shave a few seconds off rebuilds. Probably not worth it, in your case, unless you're invalidating the cached layer often (adding or removing deps, intentionally building without layer caching to ensure you have the latest packages).

Hadolint is another tool worth checking out if you like spending time messing with Dockerfiles: https://github.com/hadolint/hadolint

With Depot, we make use of two Dockerfile linters, hadolint and a set of Dockerfile linter rules that Semgrep has written to make a bit of a smarter Dockerfile linter.

# Download hadolint wget https://github.com/hadolint/hadolint/releases/download/v2.12.0/hadolint-Linux-x86_64 # Download SHA256 checksum wget https://github.com/hadolint/hadolint/releases/download/v2.12.0/hadolint-Linux-x86_64.sha256 # Validate the checksum sha256sum -c hadolint-Linux-x86_64.sha256 # Make the file executable chmod + ./hadolint-Linux-x86_64 # Rename the file mv hadolint-Linux-x86_64 hadolint

The most common linter I've seen and used it Hadolint, which does: https://github.com/hadolint/hadolint/wiki/DL3002 I didn't bother checking to see if alternatives also support this as well though.

Trivy: security scanner for IaC and dependencies

Prior to deploying kubernetes manifest files to EKS Cluster, supplementary steps need to be added to prevent security and misconfiguration issue by using both *Checkov *and Trivy . Also, we will use seperate ArgoCD account from admin user that we’ve used in the previous lab. This will follow ArgoCD RBAC rule to secure ArgoCD and EKS cluster ultimately.

Regularly scan your Docker images for vulnerabilities using tools like Trivy or Clair.

Since I'm working on a Windows machine, I went straight to the Trivy website (https://aquasecurity.github.io/trivy/) to download the latest release. The official website is the best place to get the latest version of Trivy. This direct approach gives me more control over the installation process.

There are also pre-built packages available for various Linux distros, or grab the binary from GitHub releases: https://github.com/aquasecurity/trivy/releases

name: CI on: [push, pull_request] jobs: trivy: runs-on: ubuntu-latest steps: - name: Checkout code uses: actions/checkout@v2 - name: Set up Trivy run: | sudo apt-get update && sudo apt-get install -y wget wget https://github.com/aquasecurity/trivy/releases/download/v0.28.1/trivy_0.28.1_Linux-64bit.deb sudo dpkg -i trivy_0.28.1_Linux-64bit.deb - name: Scan Docker image run: | docker build -t my-docker-image:latest . trivy image my-docker-image:latest - name: Scan Kubernetes manifests run: | trivy k8s --file /path/to/manifest.yaml

4. Trivy: https://github.com/aquasecurity/trivy Trivy is a versatile tool that scans for vulnerabilities in your containers, and also checks for vulnerabilities in your application dependencies.
