  • allows for HTTP Method Override using the headerX-HTTP-Method-Overrideor through query string parameter:_method
  • create custom bins for experimenting log collection

Installation

Requirements

brew install redis
brew services start redis

Redis should be now running on localhost:6379 Mockbin will start without redis but you wont be able to set or get response bins.

git clone https://github /Kong/mockbin.git./mockbin
cdmockbin
cp.env.sample.env
brew install fnm
fnm use
npm install

Note: nvm, n or volta can be used instead of fnm.

Software Bill of materials

Kong Insomnia Mockbin produces SBOMs for the below categories:

  • For docker container images
  • For source code repository

The SBOMs are available to download at:

  • Github Release / Tag Assets
  • Github workflow assets for other workflow runs

Verify a container image signature

Docker container images are now signed using cosign with signatures published to aGithub Container registrywithinsomnia-mockbinrepository.

Steps to verify signatures for signed Kong Insomnia Mockbin Docker container images in two different ways:

A minimal example, used to verify an image without leveraging any annotations. For the minimal example, you only need Docker details, a GitHub repo name, and a GitHub workflow filename.

cosign verify \
ghcr.io/kong/insomnia-mockbin:<tag>@sha256:<digest> \
--certificate-oidc-issuer='https://token.actions.githubusercontent ' \
--certificate-identity-regexp='https://github /Kong/insomnia-mockbin/.github/workflows/release.yaml'

A complete example, leveraging optional annotations for increased trust. For the complete example, you need the same details as the minimal example, as well as any of the optional annotations you wish to verify:

cosign verify \
ghcr.io/kong/insomnia-mockbin:<tag>@sha256:<digest> \
--certificate-oidc-issuer='https://token.actions.githubusercontent ' \
--certificate-identity-regexp='https://github /Kong/insomnia-mockbin/.github/workflows/release.yaml' \
-a repo='Kong/insomnia-mockbin' \
-a workflow='Package & Release'

Verify a container image provenance

Kong Insomnia Mockbin produces build provenance for docker container images forGithub tags,which can be verified using cosign / slsa-verifier with attestations published to aGithub Container registrywithinsomnia-mockbinrepository.

Steps to verify provenance for signed Kong Insomnia Mockbin Docker container images:

  1. Fetch the image<manifest_digest>using regctl:

    regctl image digest ghcr.io/kong/insomnia-mockbin:<tag>
    
  2. A minimal example, used to verify an image without leveraging any annotations. For the minimal example, you only need Docker Image manifest, a GitHub repo name.

    cosign verify-attestation \
    ghcr.io/kong/insomnia-mockbin:<tag>@sha256:<manifest_digest> \
    --type='slsaprovenance' \
    --certificate-oidc-issuer='https://token.actions.githubusercontent ' \
    --certificate-identity-regexp='^https://github /slsa-framework/slsa-github-generator/.github/workflows/generator_container_slsa3.yml@refs/tags/v[0-9]+.[0-9]+.[0-9]+$'
    
    slsa-verifier verify-image \
    ghcr.io/kong/insomnia-mockbin:<tag>@sha256:<manifest_digest> \
    --print-provenance \
    --source-uri 'github /Kong/insomnia-mockbin'
    
  3. A complete example, leveraging optional annotations for increased trust. For the complete example, you need the same details as the minimal example, as well as any of the optional annotations you wish to verify:

    cosign verify-attestation \
    ghcr.io/kong/insomnia-mockbin:<tag>@sha256:<manifest_digest> \
    --type='slsaprovenance' \
    --certificate-oidc-issuer='https://token.actions.githubusercontent ' \
    --certificate-identity-regexp='^https://github /slsa-framework/slsa-github-generator/.github/workflows/generator_container_slsa3.yml@refs/tags/v[0-9]+.[0-9]+.[0-9]+$' \
    --certificate-github-workflow-repository='Kong/insomnia-mockbin' \
    --certificate-github-workflow-name='Package & Release'
    
    slsa-verifier verify-image \
    ghcr.io/kong/insomnia-mockbin:<tag>@sha256:<manifest_digest> \
    --print-provenance \
    --source-uri 'github /Kong/insomnia-mockbin' \
    --source-tag '<tag>'
