Anchore Engine

For the most up-to-date information on Anchore Engine, Anchore CLI, and other Anchore software, please refer to the Anchore Documentation

The Anchore Engine is an open source project that provides a centralized service for inspection, analysis and certification of container images. The Anchore engine is provided as a Docker container image that can be run standalone (a docker-compose file is provided), or on an orchestration platform such as Kubernetes, Docker Swarm, Rancher or Amazon ECS.

The Anchore engine can be accessed directly through a RESTful API or via the Anchore CLI.

Using the Anchore Engine, container images can be downloaded from Docker V2 compatible container registries, and then evaluated against user defined policies. The Anchore Engine can integrate with Anchore's Navigator service, allowing you to define policies and whitelists using a graphical editor that are automatically synchronized to the Anchore Engine.

Installation

The Anchore Engine is distributed as a Docker Image available from DockerHub.

A PostgreSQL database is required to provide persistent storage for the Anchore Engine.

The Anchore Engine requires a single volume used to store configuration information and optionally certificates for TLS.

Configuration

1. Create a directory to expose as a volume containing Anchore Engine configuration files (we use /root/aevolume here but you can use non-root paths and adjust the samepl config/docker-compose configuration files accordingly)

mkdir -p ~/aevolume/config

2. Download the sample configuration file config.yaml from the scripts/docker-compose directory of the github project and save into the directory created in step #1

cd ~/aevolume/config && curl -O https://raw.githubusercontent.com/anchore/anchore-engine/master/scripts/docker-compose/config.yaml && cd -

3. Edit the config.yaml file to specify your email and password for the admin user.

    credentials:
      default_user: 'admin'
      users:
         admin:
           password: 'foobar'
           email: '[email protected]'
           external_service_auths:
           #  anchoreio:
           #    anchorecli:
           #      auth: 'myanchoreiouser:myanchoreiopass'
           #auto_policy_sync: True

4. Make other changes to config.yaml to enable additional features or tune to your environment (not required for basic usage)

5. Create a directory to expose as a volume for PostgreSQL data

mkdir -p ~/aevolume/db/

Running Anchore Engine using Docker Compose

To run Anchore Engine using Docker Compose the following additional steps must be performed:

1. Change to the directory in which you have created the config and db subdirectories.

cd ~/aevolume

2. Download the docker-compose.yaml file from the scripts/docker-compose directory of the github project.

curl -O https://raw.githubusercontent.com/anchore/anchore-engine/master/scripts/docker-compose/docker-compose.yaml

3. Run docker-compose pull to instruct Docker to download the required container images from DockerHub.

4. To start Anchore Engine run docker-compose up -d

5. To stop the Anchore Engine run docker-compose down

Getting Started using the CLI

The Anchore CLI is an easy way to control the Anchore Engine.

The Anchore CLI can be installed using the Python pip command. See Anchore CLI for instructions.

By default the Anchore CLI will try to connect to the Anchore Engine at http://localhost/v1 with no authentication. The username, password and URL for the server can be passed to the Anchore CLI as command line arguments. These values are the ones defined in your ~/aevolume/config/config.yaml.

--u   TEXT   Username     eg. admin
--p   TEXT   Password     eg. foobar
--url TEXT   Service URL  eg. http://localhost:8228/v1

Rather than passing these parameters for every call to the cli they can be set as environment variables.

ANCHORE_CLI_URL=http://myserver.example.com:8228/v1
ANCHORE_CLI_USER=admin
ANCHORE_CLI_PASS=foobar

Add an image to the Anchore Engine:

anchore-cli image add docker.io/library/debian:latest

List images analyzed by the Anchore Engine:

anchore-cli image list

Get a specific image and see when its status goes to analyzed:

anchore-cli image get docker.io/library/debian:latest

Obtain the results of the vulnerability scan on an image:

anchore-cli image vuln docker.io/library/debian:latest os

List operating system packages present in an image:

anchore-cli image content docker.io/library/debian:latest os

Subscribe to receive webhook notifications when new CVEs are added to an update:

anchore-cli subscription activate vuln_update docker.io/library/debian:latest

API

Each service implements its own API, and all APIs are defined in Swagger/OpenAPI spec. You can find each in the anchore_engine/services/<servicename>/api/swagger directory.

For the external API definition (the user-facing service), see External API Spec.
