GitHub Action
Docker Scout
GitHub Action to run the Docker Scout CLI as part of your workflows.
You can pick one of the following commands to run:
quickview
: get a quick overview of an image, base image and available recommendationscompare
: compare an image to a second one (for instance tolatest
)cves
: display vulnerabilities of an imagerecommendations
: display available base image updates and remediation recommendationssbom
: generate the SBOM of the imageenvironment
: record an image to an environment
You can run one or multiple commands in the same GitHub Action run. Use a comma separated list to run several commands.
command |
required | string |
Single command to run or comma separated list of commands to run in order. Possible values:
|
The commands will be run in the order of the value, and will share the same parameters.
For instance, if you built an image and want to display a quickview
as well as to compare
it against the latest indexed one, set the action as following:
command: quickview,compare
image: ${{ steps.meta.outputs.tags }}
to-latest: true
To use scout
features you need to be authenticated against Docker Hub.
You can use the parameters below to authenticate, or you can use the docker/login-action
.
dockerhub-user |
optional | string |
Docker Hub user id |
dockerhub-password |
optional | string |
Docker Hub password or PAT |
registry-user |
required to pull from other private registry | string |
Registry user id to pull images |
registry-password |
required to pull from other private registry | string |
Registry password or PAT to pull images |
image |
optional (*) | string |
Prefixed name of the image, directory or archive to operate on |
platform |
optional current platform by default | string |
Platform of the image to analyze (or the current platform) |
ref |
optional default is empty | string |
Reference to use if the provided tarball containers multiple images, only with archives |
(*) If image
is not set (or empty) the most recently built image, if any, will be used instead.
The image
field can be prefixed to indicate the type of content to analyse.
If no prefix is set, the image://
prefix is used.
Available prefixes:
image://
: optional prefix, the target is an image that first will be resolved locally then, if not found, will be resolved to the associated registrylocal://
: only resolve the image from the local image storeregistry://
: do not use the local image store, only use the registryoci-dir://
: local directory to be read as an OCI directoryarchive://
: image archive generated bydocker save
command, as atar
filefs://
: local directory or filesbom://
SPDX file or in-toto attestation file with SPDX predicate orsyft
json SBOM file
Namespace of the Docker Organization is required to match the query with the right data.
When using environments (for instance to compare an image to the one from a defined environment, or when comparing to the latest indexed) organization
parameter is required.
organization |
required to compare to environments/latest indexed required to manage environments optional in other cases, default empty |
string |
Namespace of the Docker organization |
By default the Markdown output of the command (if supported) will be displayed as a Job Summary. This can be disabled if needed.
summary |
optional default is true |
boolean |
Display output as Job Summary |
When triggered by a pull_request
event, the output of the scout command can be written as a comment.
This behaviour is enabled by default.
By default one single comment per job step will be kept and updated at each run.
If you prefer to keep previous comments but hide them, set the keep-previous-comments
parameter to true
.
pull-requests: write
permission is required to allow the GitHub action to create the comment.

optional default is github.token |
string |
GitHub Token to create the comment |
write-comment |
optional default is true |
boolean |
Boolean, write a comment with scout output |
keep-previous-comments |
optional default is false |
boolean |
If set, keep but hide previous comment. If not set, keep and update one single comment per job |
The text version of the command output will be displayed in the logs. The markdown version (if exists) of the command output will be set as an output of the step, using the command name as identifier, and will be displayed as Pull Request comment or Step Summary.
