Trivy (tri pronounced like trigger, vy pronounced like envy) is a simple and comprehensive vulnerability scanner for containers and other artifacts.
A software vulnerability is a glitch, flaw, or weakness present in the software or in an Operating System.
Trivy detects vulnerabilities of OS packages (Alpine, RHEL, CentOS, etc.) and application dependencies (Bundler, Composer, npm, yarn, etc.).
Trivy is easy to use. Just install the binary and you're ready to scan. All you need to do for scanning is to specify a target such as an image name of the container.
It is considered to be used in CI. Before pushing to a container registry or deploying your application, you can scan your local container image and other artifacts easily. See here for details.
- Detect comprehensive vulnerabilities
- OS packages (Alpine, Red Hat Universal Base Image, Red Hat Enterprise Linux, CentOS, Oracle Linux, Debian, Ubuntu, Amazon Linux, openSUSE Leap, SUSE Enterprise Linux, Photon OS and Distroless)
- Application dependencies (Bundler, Composer, Pipenv, Poetry, npm, yarn and Cargo)
- Simple
- Specify only an image name or artifact name
- See Quick Start and Examples
- Fast
- The first scan will finish within 10 seconds (depending on your network). Consequent scans will finish in single seconds.
- Unlike other scanners that take long to fetch vulnerability information (~10 minutes) on the first run, and encourage you to maintain the a durable vulnerability database, Trivy is stateless and requires no maintenance or preparation.
- Easy installation
apt-get install,yum installandbrew installis possible (See Installation)- No pre-requisites such as installation of DB, libraries, etc. (The exception is that you need
rpminstalled to scan images based on RHEL/CentOS. This is automatically included if you use our installers or the Trivy container image. See Vulnerability Detection for background information.)
- High accuracy
- Especially Alpine Linux and RHEL/CentOS
- Other OSes are also high
- DevSecOps
- Suitable for CI such as Travis CI, CircleCI, Jenkins, GitLab CI, etc.
- See CI Example
- Support multiple formats
- container image
- A local image in Docker Engine which is running as a daemon
- A remote image in Docker Registry such as Docker Hub, ECR, GCR and ACR
- A tar archive stored in the
docker saveformatted file - An image directory compliant with OCI Image Format
- local filesystem
- remote git repository
- container image

Replace {TRIVY_VERSION} with the latest released version of Trivy. You can find the latest releases on this page: https://github.com/aquasecurity/trivy/releases
Add repository setting to /etc/yum.repos.d.
$ sudo vim /etc/yum.repos.d/trivy.repo
[trivy]
name=Trivy repository
baseurl=https://aquasecurity.github.io/trivy-repo/rpm/releases/$releasever/$basearch/
gpgcheck=0
enabled=1
$ sudo yum -y update
$ sudo yum -y install trivy
or
$ rpm -ivh https://github.com/aquasecurity/trivy/releases/download/{TRIVY_VERSION}/trivy_{TRIVY_VERSION}_Linux-64bit.rpm
Add repository to /etc/apt/sources.list.d.
$ sudo apt-get install wget apt-transport-https gnupg lsb-release
$ wget -qO - https://aquasecurity.github.io/trivy-repo/deb/public.key | sudo apt-key add -
$ echo deb https://aquasecurity.github.io/trivy-repo/deb $(lsb_release -sc) main | sudo tee -a /etc/apt/sources.list.d/trivy.list
$ sudo apt-get update
$ sudo apt-get install trivy
or
$ sudo apt-get install rpm
$ wget https://github.com/aquasecurity/trivy/releases/download/{TRIVY_VERSION}/trivy_{TRIVY_VERSION}_Linux-64bit.deb
$ sudo dpkg -i trivy_{TRIVY_VERSION}_Linux-64bit.deb
Package trivy-bin can be installed from the Arch User Repository. Examples:
pikaur -Sy trivy-bin
or
yay -Sy trivy-bin
You can use homebrew on macOS.
$ brew install aquasecurity/trivy/trivy
This script downloads Trivy binary based on your OS and architecture.
$ curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/master/contrib/install.sh | sh -s -- -b /usr/local/bin
Get the latest version from this page, and download the archive file for your operating system/architecture. Unpack the archive, and put the binary somewhere in your $PATH (on UNIX-y systems, /usr/local/bin or the like). Make sure it has execution bits turned on.
You also need to install rpm command for scanning images based on RHEL/CentOS.
$ mkdir -p $GOPATH/src/github.com/aquasecurity
$ cd $GOPATH/src/github.com/aquasecurity
$ git clone https://github.com/aquasecurity/trivy
$ cd trivy/cmd/trivy/
$ export GO111MODULE=on
$ go installYou also need to install rpm command for scanning images based on RHEL/CentOS.
Simply specify an image name (and a tag). The latest tag should be avoided as problems occur with the image cache. See Clear image caches.
$ trivy image [YOUR_IMAGE_NAME]
For example:
$ trivy image python:3.4-alpine

Replace [YOUR_CACHE_DIR] with the cache directory on your machine.
$ docker run --rm -v [YOUR_CACHE_DIR]:/root/.cache/ aquasec/trivy [YOUR_IMAGE_NAME]
Example for macOS:
$ docker run --rm -v $HOME/Library/Caches:/root/.cache/ aquasec/trivy python:3.4-alpine
If you would like to scan the image on your host machine, you need to mount docker.sock.
$ docker run --rm -v /var/run/docker.sock:/var/run/docker.sock \
-v $HOME/Library/Caches:/root/.cache/ aquasec/trivy python:3.4-alpine
Please re-pull latest aquasec/trivy if an error occurred.

Scan a filesystem (such as a host machine, a virtual machine image, or an unpacked container image filesystem).
Trivy will look for vulnerabilities based on lock files such as Gemfile.lock and package-lock.json.
$ trivy fs /path/to/project
Scan your container from inside the container.
$ docker run --rm -it alpine:3.11
/ # curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/master/contrib/install.sh | sh -s -- -b /usr/local/bin
/ # trivy fs /
Scan your image as part of the build process by embedding Trivy in the Dockerfile. This approach can be used to update Dockerfiles currently using Aqua’s [Microscanner][https://github.com/aquasecurity/microscanner].
$ cat Dockerfile
FROM alpine:3.7
RUN apk add curl \
&& curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/master/contrib/install.sh | sh -s -- -b /usr/local/bin \
&& trivy filesystem --exit-code 1 --no-progress /
$ docker build -t vulnerable-image .
Scan your remote git repository
$ trivy repo https://github.com/knqyf263/trivy-ci-test
Only public repositories are supported.
Simply specify an image name (and a tag).
$ trivy image knqyf263/vuln-image:1.2.3

The lightweight DB doesn't contain vulnerability detail such as descriptions and references. Because of that, the size of the DB is smaller and the download is faster.
This option is useful when you don't need vulnerability details and is suitable for CI/CD. To find the additional information, you can search vulnerability details on the NVD website. https://nvd.nist.gov/vuln/search
$ trivy image --light alpine:3.10

Trivy has client/server mode. Trivy server has vulnerability database and Trivy client doesn't have to download vulnerability database. It is useful if you want to scan images at multiple locations and do not want to download the database at every location.
At first, you need to launch Trivy server. It downloads vulnerability database automatically and continue to fetch the latest DB in the background.
$ trivy server --listen localhost:8080

--only-update, --refresh and --auto-refresh are deprecated since they are unnecessary now. These options will be removed at the next version
Scan your image automatically as part of your CI workflow, failing the workflow if a vulnerability is found. When you don't want to fail the test, specify --exit-code 0.
Since in automated scenarios such as CI/CD you are only interested in the end result, and not the full report, use the --light flag to optimize for this scenario and get fast results.

See this blog post for an example of using Trivy within AWS CodePipeline.
Trivy can download images from a private registry, without installing Docker or any other 3rd party tools.
That's because it's easy to run in a CI process.
All you have to do is install Trivy and set ENV vars.
But, I can't recommend using ENV vars in your local machine to you.
Docker Hub needs TRIVY_AUTH_URL, TRIVY_USERNAME and TRIVY_PASSWORD.
You don't need to set ENV vars when download from public repository.
export TRIVY_AUTH_URL=https://registry.hub.docker.com
export TRIVY_USERNAME={DOCKERHUB_USERNAME}
export TRIVY_PASSWORD={DOCKERHUB_PASSWORD}Trivy uses AWS SDK. You don't need to install aws CLI tool.
You can use AWS CLI's ENV Vars.
Trivy uses Google Cloud SDK. You don't need to install gcloud command.
If you want to use target project's repository, you can settle via GOOGLE_APPLICATION_CREDENTIAL.
# must set TRIVY_USERNAME empty char
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credential.jsonBasicAuth server needs TRIVY_USERNAME and TRIVY_PASSWORD.
export TRIVY_USERNAME={USERNAME}
export TRIVY_PASSWORD={PASSWORD}
# if you want to use 80 port, use NonSSL
export TRIVY_NON_SSL=trueThe unfixed/unfixable vulnerabilities mean that the patch has not yet been provided on their distribution. Trivy doesn't support self-compiled packages/binaries, but official packages provided by vendors such as Red Hat and Debian.
| OS | Supported Versions | Target Packages | Detection of unfixed vulnerabilities |
|---|---|---|---|
| Alpine Linux | 2.2 - 2.7, 3.0 - 3.12 | Installed by apk | NO |
| Red Hat Universal Base Image | 7, 8 | Installed by yum/rpm | YES |
| Red Hat Enterprise Linux | 6, 7, 8 | Installed by yum/rpm | YES |
| CentOS | 6, 7 | Installed by yum/rpm | YES |
| Oracle Linux | 5, 6, 7, 8 | Installed by yum/rpm | NO |
| Amazon Linux | 1, 2 | Installed by yum/rpm | NO |
| openSUSE Leap | 42, 15 | Installed by zypper/rpm | NO |
| SUSE Enterprise Linux | 11, 12, 15 | Installed by zypper/rpm | NO |
| Photon OS | 1.0, 2.0, 3.0 | Installed by tdnf/yum/rpm | NO |
| Debian GNU/Linux | wheezy, jessie, stretch, buster | Installed by apt/apt-get/dpkg | YES |
| Ubuntu | 12.04, 14.04, 16.04, 18.04, 18.10, 19.04 | Installed by apt/apt-get/dpkg | YES |
| Distroless | Any | Installed by apt/apt-get/dpkg | YES |
RHEL, CentOS, Oracle Linux, SUSE, Amazon Linux and Photon OS package information is stored in a binary format, and Trivy uses the rpm executable to parse this information when scanning an image based on RHEL or CentOS. The Trivy container image includes rpm, and the installers include it as a dependency. If you installed the trivy binary using wget or curl, or if you build it from source, you will also need to ensure that rpm is available.
Distroless: https://github.com/GoogleContainerTools/distroless
Trivy automatically detects the following files in the container and scans vulnerabilities in the application dependencies.
- Ruby
- Gemfile.lock
- Python
- Pipfile.lock
- poetry.lock
- PHP
- composer.lock
- Node.js
- package-lock.json
- yarn.lock
- Rust
- Cargo.lock
The path of these files does not matter.
Example: https://github.com/aquasecurity/trivy-ci-test/blob/master/Dockerfile
Trivy scans a tar image with the following format.
- Docker Image Specification (https://github.com/moby/moby/tree/master/image/spec)
- Moby Project (https://github.com/moby/moby/)
- Buildah, Podman (https://github.com/containers/buildah)
- img (https://github.com/genuinetools/img)
- Kaniko
- PHP
- Python
- Ruby
- Node.js
- Rust

- Open Source CVE Scanner Round-Up: Clair vs Anchore vs Trivy
- Docker Image Security: Static Analysis Tool Comparison – Anchore Engine vs Clair vs Trivy
Clair uses alpine-secdb. However, the purpose of this database is to make it possible to know what packages has backported fixes. As README says, it is not a complete database of all security issues in Alpine.
Trivy collects vulnerability information in Alpine Linux from Alpine Linux aports repository.
Then, those vulnerabilities will be saved on vuln-list.
alpine-secdb has 6959 vulnerabilities (as of 2019/05/12).
vuln-list has 11101 vulnerabilities related to Alpine Linux (as of 2019/05/12).
There is a difference in detection accuracy because the number of vulnerabilities is nearly doubled.
In addition, Trivy analyzes the middle layers as well to find out which version of the library was used for static linking.
Clair can not handle the following cases because it analyzes the image after applying all layers.
RUN apk add --no-cache sqlite-dev \
&& wget https://xxx/yyy.tar.gz \
&& tar zxvf yyy.tar.gz && cd yyy \
&& make && make install \
&& apk del sqlite-dev
And as many people know, it is difficult to select a Clair client because many clients are deprecated.
Trivy is a stand-alone tool and can scan very fast. This means it's very easy to use in CI/CD.
Finally, Trivy can also detect vulnerabilities in application dependent libraries such as Bundler, Composer, Pipenv, etc.
Similar to Clair, there is a difference in detection accuracy on Alpine Linux.
Then, as noted above, Anchore Engine does not detect unfixable vulnerabilities on RHEL/CentOS, whereas Trivy does.
Also, Anchore Engine needs some steps to start scanning.
Trivy is much easier to use.
As Quay uses Clair internally, it has the same accuracy as Clair. Docker Hub can scan only official images. GCR hardly detects vulnerabilities on Alpine Linux. Also, it is locked to a specific registry.
Trivy can be used regardless of the registry, and it is easily integrated with CI/CD services.
On 19 August 2019, Trivy's repositories moved from knqyf263/trivy to aquasecurity/trivy. If you previously installed Trivy you should update any scripts or package manager records as described in this section.
If you have a script that installs Trivy (for example into your CI pipelines) you should update it to obtain it from the new location by replacing knqyf263/trivy with aquasecurity/trivy.
For example:
# Before
$ wget https://github.com/knqyf263/trivy/releases/download/v${VERSION}/trivy_${VERSION}_Linux-64bit.tar.gz
# After
$ wget https://github.com/aquasecurity/trivy/releases/download/v${VERSION}/trivy_${VERSION}_Linux-64bit.tar.gzUse https://aquasecurity.github.io instead of https://knqyf263.github.io.
$ yum remove trivy
$ sed -i s/knqyf263/aquasecurity/g /etc/yum.repos.d/trivy.repo
$ yum update
$ yum install trivyUse https://aquasecurity.github.io instead of https://knqyf263.github.io.
$ apt-get remove --purge trivy
$ sed -i s/knqyf263/aquasecurity/g /etc/apt/sources.list.d/trivy.list
$ apt-get update
$ apt-get install trivyTap aquasecurity/trivy
$ brew uninstall --force trivy
$ brew untap knqyf263/trivy
$ brew install aquasecurity/trivy/trivyNo need to fix.
$ brew tap aquasecurity/trivy
