Trivy (tri pronounced like trigger, vy pronounced like envy) is a simple and comprehensive vulnerability scanner for containers.
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 an image name of container.
It is considered to be used in CI. Before pushing to a container registry, you can scan your local container image easily. See here for details.
- Detect comprehensive vulnerabilities
- OS packages (Alpine, Red Hat Universal Base Image, Red Hat Enterprise Linux, CentOS, Debian and Ubuntu)
- Application dependencies (Bundler, Composer, Pipenv, Poetry, npm, yarn and Cargo)
- Simple
- Specify only an image name
- See Quick Start and Examples
- Easy installation
- No need for prerequirements such as installation of DB, libraries, etc.
apt-get install,yum installandbrew installis possible (See Installation)
- High accuracy
- Especially Alpine Linux and RHEL/CentOS (See Comparison with other scanners)
- Other OSes are also high
- DevSecOps
- Suitable for CI such as Travis CI, CircleCI, Jenkins, etc.
- See CI Example
Add repository setting to /etc/yum.repos.d.
$ sudo vim /etc/yum.repos.d/trivy.repo
[trivy]
name=Trivy repository
baseurl=https://knqyf263.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/knqyf263/trivy/releases/download/v0.0.15/trivy_0.0.15_Linux-64bit.rpm
Replace [CODE_NAME] with your code name
CODE_NAME: wheezy, jessie, stretch, buster, trusty, xenial, bionic
$ sudo apt-get install apt-transport-https gnupg
$ wget -qO - https://knqyf263.github.io/trivy-repo/deb/public.key | sudo apt-key add -
$ echo deb https://knqyf263.github.io/trivy-repo/deb [CODE_NAME] 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/knqyf263/trivy/releases/download/v0.0.15/trivy_0.0.15_Linux-64bit.deb
$ sudo dpkg -i trivy_0.0.15_Linux-64bit.deb
You can use homebrew on Mac OS.
$ brew install knqyf263/trivy/trivy
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 need to install rpm command for scanning RHEL/CentOS.
$ mkdir -p $GOPATH/src/github.com/knqyf263
$ cd $GOPATH/src/github.com/knqyf263
$ git clone https://github.com/knqyf263/trivy
$ cd trivy/cmd/trivy/
$ export GO111MODULE=on
$ go installSimply specify an image name (and a tag). The latest tag should be avoided as problems occur with cache.. See Clear image caches
$ trivy [YOUR_IMAGE_NAME]
For example:
$ trivy python:3.4-alpine

Replace [YOUR_CACHE_DIR] with the cache directory on your machine.
$ docker run --rm -v [YOUR_CACHE_DIR]:/root/.cache/ knqyf263/trivy [YOUR_IMAGE_NAME]
Example for macOS:
$ docker run --rm -v $HOME/Library/Caches:/root/.cache/ knqyf263/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/ knqyf263/trivy python:3.4-alpine
Please re-pull latest knqyf263/trivy if an error occured.

Trivy can download images from private registry, without installing Docker and any 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.
| OS | Supported Versions | Target Packages | Detection of unfixed vulnerabilities |
|---|---|---|---|
| Alpine Linux | 2.2 - 2.7, 3.0 - 3.10 | 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 |

Trivy automatically detects the following files in the container and scans vulnerabilities in the application dependencies.
- Gemfile.lock
- Pipfile.lock
- poetry.lock
- composer.lock
- package-lock.json
- yarn.lock
- Cargo.lock
The path of these files does not matter.

The following bar charts show the results of scanning composer:1.7.2 and crate:3.2.2 by container scanners. These images were selected randomly.
Scanners: Clair, Quay, MicroScanner(Free), Docker Hub, Anchore Engine
See spreadsheet for details.
In this case, the union of vulnerabilities detected by all vulnerability scanners is used as a data set.
NOTE
- There may be vulnerabilities that all scanners could not detect.
- There may be a mistake because I have confirmed the correctness manually.
The results of composer:1.7.2 using Alpine Linux 3.7.1 (as of 2019/05/12).
Trivy has high accuracy and high precision, while GCR did not detect any vulnerability. Although Docker Hub has many True Positive, it also has many False Positive.
The results of crate:3.2.2 using CentOS 7.6.1810. (as of 2019/05/14).
The following chart includes only fixable vulnerabilities.
Most scanners only detect patched/fixable vulnerabilities on RHEL/CentOS, but Trivy also detects unpatched/unfixable vulnerabilities.
This graph includes unfixable vulnerabilities as well.
In the case of other OS, the result is similar to other container scanners.
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 Redmine.
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 with 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 layer as well and 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.
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 seems to use Clair internally, it has the same accuracy than 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. In addition, it is easy to be integrated with CI/CD services.
