Bullfrog\n\nIncrease the security of your Github Actions workflows using Bullfrog! With Bullfrog, you can easily control all your outbound network connections made from within your Github Actions workflows by defining a list of IPs and/or domains that you want to allow.\n\nNot sure what IPs or domains? Simply use the default `egress-policy: audit` mode to get a list of all outbound network connections, without impacting your existing workflows.\n\n## Documentation\n\nFor complete documentation, visit [docs.bullfrogsec.com](https://docs.bullfrogsec.com).\n\n## Usage\n\n\u003c!-- start usage --\u003e\n\n```yaml\n# This action should be the first step of your job, and should be loaded on every separate job.\n# If this action is not loaded first, it will not be able to see or block any requests that occured prior to the action running.\n- uses: bullfrogsec/bullfrog@c8e5fff94e0050c0cef9b9596c55cf3d9c53ba2c # v0.9.2\n  with:\n    # List of IPs to allow outbound connections to.\n    # By default, only localhost and IPs required for the essential operations of Github Actions are allowed.\n    allowed-ips:\n\n    # List of domains to allow outbound connections to.\n    # Wildcards are accepted. For example, if allowing `*.google.com`, this will allow `www.google.com`, `console.cloud.google.com` but not `google.com`.\n    # By default, only domains required for essential operations of Github Actions and uploading job summaries are allowed.\n    # Refer to https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners/about-github-hosted-runners#communication-requirements-for-github-hosted-runners-and-github for additional domains that should be allowed for additional Github Actions features.\n    allowed-domains:\n\n    # Controls the policy for DNS requests when `egress-policy` is set to `block`.\n    #\n    #  - `allowed-domains-only` (default): Allows DNS requests only for domains specified in `allowed-domains`.\n    #  - `any`: Allows any DNS requests.\n    #\n    # Default: `allowed-domains-only`\n    dns-policy:\n\n    # The egress policy to enforce. Valid values are `audit` and `block`.\n    # Default: audit\n    egress-policy:\n\n    # Enable this option to allow steps to execute commands with sudo.\n    # This is useful for workflows that require elevated privileges to perform certain tasks.\n    # Options: `true` (default) or `false`.\n    enable-sudo:\n\n    # API token for submitting connection results to the Bullfrog control plane. If not provided, results will not be published.\n    api-token:\n```\n\n\u003c!-- end usage --\u003e\n\n## Scenarios\n\n- [Default](#default)\n- [Block every outbound connections](#block-every-outbound-connections)\n- [Only allow requests to domains required for pulling a docker image from the docker hub](#only-allow-requests-to-domains-required-for-pulling-a-docker-image-from-the-docker-hub)\n- [Only allow requests to a specific IP address without blocking DNS requests](#only-allow-requests-to-a-specific-ip-address-without-blocking-dns-requests)\n\n### Default\n\nThe default usage will run in audit mode and will not block any request.\n\n```yaml\n- uses: bullfrogsec/bullfrog@c8e5fff94e0050c0cef9b9596c55cf3d9c53ba2c # v0.9.2\n```\n\n### Block every outbound connections\n\n```yaml\n- uses: bullfrogsec/bullfrog@c8e5fff94e0050c0cef9b9596c55cf3d9c53ba2c # v0.9.2\n  with:\n    egress-policy: block\n```\n\n### Only allow requests to domains required for pulling a docker image from the docker hub\n\n```yaml\n- uses: bullfrogsec/bullfrog@c8e5fff94e0050c0cef9b9596c55cf3d9c53ba2c # v0.9.2\n  with:\n    egress-policy: block\n    allowed-domains: |\n      *.docker.com\n      docker.io\n      *.docker.io\n```\n\n### Only allow requests to a specific IP address without blocking DNS requests\n\n```yaml\n- uses: bullfrogsec/bullfrog@c8e5fff94e0050c0cef9b9596c55cf3d9c53ba2c # v0.9.2\n  with:\n    egress-policy: block\n    allowed-ips: |\n      1.2.3.4\n    dns-policy: any\n```\n\n## Reviewing blocked or unallowed outbound requests\n\nYou can view blocked or unallowed outbound requests in the workflow summary.\n\n## Control Plane\n\nMonitor connection results across all workflows and repositories in your GitHub organization using the Bullfrog control plane. Visit [bullfrogsec.com](https://bullfrogsec.com) to create a free account and get your API token. A free tier is available to help you gain visibility into all outbound connections across your organization.\n\n## Limitations\n\n- This action is currently only supporting Github-hosted runners on Ubuntu (`ubuntu-latest`, `ubuntu-22.04` and `ubuntu-24.04`).\n- Jobs running in [containers](https://docs.github.com/en/actions/writing-workflows/choosing-where-your-workflow-runs/running-jobs-in-a-container) are not supported.\n- Packets sent using the raw IP layer will bypass the agent responsible for the egress filtering. For this reason, we highly recommend using the `enable-sudo: false` to prevent usage of the raw IP layer.\n\n## Support or Feedback\n\nIf you need support or have any feedback to share, join us on [Reddit](https://www.reddit.com/r/bullfrogsec).
