Snyk helps to find and fix known vulnerabilities in your dependencies, both ad hoc and as part of your CI (Build) system.

We are using "Snyk CLI" you should Snyk API token in order to use it.

SNYK_TOKEN env variable with your Snyk API token and add "snyk" in TASKS environment variable.

Reapsaw languages support:

How to build application code base

NodeJS Playbook

1. Before scan install application modules:

npm install

2. Add snyk in TASKS environment variable:

$ docker run --name sast --rm -d \
       -e TASKS="snyk" \
       -v <PATH_TO_FOLDER_WITH_PROJECT_CODE_AFTER_BUILD>:/code \
       -e SNYK_TOKEN=<SNYK_TOKEN> \
       sast:latest

3. Report example:

Note: For the findings from Snyk we are reporting top level dependencies

.NET Playbook

If you are using .Net you should add required params:

• lang='dotnet'
• sln_file=<PATH_TO_SLN_FILE> # e.g src/Project.sln

1. Build application

$ dotnet restore

$ docker run --name sast --rm -d \
        -e TASKS="snyk" \
        -v <PATH_TO_FOLDER_WITH_PROJECT_CODE_AFTER_BUILD>:/code \
        -e lang='dotnet' \
        -e sln_file=<PATH_TO_SLN_FILE> \
        -e SNYK_TOKEN=<SNYK_TOKEN> \
        sast:latest

Java Playbook

1. Build application

$ mvn build

It should work for Java other build tools if not reach out to us.

2. Run Reapsaw

Scala Playbook

1. Before scan install application modules:

$ sbt build

Python Playbook

You should specify lang as environment variable:

• lang='python'

$ docker run --name sast --rm -d \
        -e TASKS="snyk" \
        -v <PATH_TO_FOLDER_WITH_PROJECT_CODE_AFTER_BUILD>:/code \
        -e lang='python' \
        -e SNYK_TOKEN=<SNYK_TOKEN> \
        sast:latest
