See the full Snyk CLI help.
Authenticating Snyk CLI
Snyk CLI depends on Snyk.io APIs. Connect your Snyk CLI with Snyk.io by running:
Setting up language support
Depending on your project’s language, you might need to setup your language environment before using Snyk.
Scanning your project
If you are already in a folder with a supported project, start by running:
Or scan a Docker image by its tag with Snyk Container:
snyk container test ubuntu:18.04 Or a k8s file: snyk iac test /path/to/kubernetes_file.yaml
Monitoring your project
Snyk can also monitor your project periodically and alert you for new vulnerabilities. The
snyk monitor is similar to
snyk test and can be used to create a project on the Snyk website that will be continuously monitored for new vulnerabilities.

Add Snyk to your CI/CD
Snyk is really powerful when you are continuously scanning and monitoring your projects for vulnerabilities.
Use one of our integrations to stay secure.
You can authorize Snyk CLI in your CI/CD programatically:
Using a SNYK_TOKEN envvar (preferred)
SNYK_TOKEN=<SNYK_API_TOKEN> snyk test
Or using a Snyk auth command
snyk auth <SNYK_API_TOKEN> snyk test
