Installation

Homebrew (Mac OS X / Linux and WSL)

You can use Homebrew on Mac OS X or Linux and WSL (Windows Subsystem for Linux).

$ brew install habakke/dockle

RHEL/CentOS

$ VERSION=$(
 curl --silent "https://api.github.com/repos/habakke/dockle/releases/latest" | \
 grep '"tag_name":' | \
 sed -E 's/.*"v([^"]+)".*/\1/' \
) && rpm -ivh https://github.com/habakke/dockle/releases/download/v${VERSION}/dockle_${VERSION}_Linux-64bit.rpm

Debian/Ubuntu

$ VERSION=$(
 curl --silent "https://api.github.com/repos/habakke/dockle/releases/latest" | \
 grep '"tag_name":' | \
 sed -E 's/.*"v([^"]+)".*/\1/' \
) && curl -L -o dockle.deb https://github.com/habakke/dockle/releases/download/v${VERSION}/dockle_${VERSION}_Linux-64bit.deb
$ sudo dpkg -i dockle.deb && rm dockle.deb

Arch Linux

dockle-bin can be installed from the Arch User Repository. Examples:

pikaur -Sy dockle-bin

or

yay -Sy dockle-bin

Windows

$ VERSION=$(
 curl --silent "https://api.github.com/repos/habakke/dockle/releases/latest" | \
 grep '"tag_name":' | \
 sed -E 's/.*"v([^"]+)".*/\1/' \
) && curl -L -o dockle.zip https://github.com/habakke/dockle/releases/download/v${VERSION}/dockle_${VERSION}_Windows-64bit.zip
$ unzip dockle.zip && rm dockle.zip
$ ./dockle.exe [IMAGE_NAME]

Binary

You can get the latest version binary from releases page.

Download the archive file for your operating system/architecture. Unpack the archive, and put the binary somewhere in your $PATH (on UNIX-y systems, /usr/local/bin or the like).

  • NOTE: Make sure that it's execution bits turned on. (chmod +x dockle)

From source

$ GO111MODULE=off go get github.com/habakke/dockle/cmd/dockle
$ cd $GOPATH/src/github.com/habakke/dockle && GO111MODULE=on go build -o $GOPATH/bin/dockle cmd/dockle/main.go

Use Docker

There's a Dockle image on Docker Hub also. You can try dockle before installing the command.

$ VERSION=$(
 curl --silent "https://api.github.com/repos/habakke/dockle/releases/latest" | \
 grep '"tag_name":' | \
 sed -E 's/.*"v([^"]+)".*/\1/' \
) && docker run --rm -v /var/run/docker.sock:/var/run/docker.sock \
  habakke/dockle:v${VERSION} [YOUR_IMAGE_NAME]

You only need -v /var/run/docker.sock:/var/run/docker.sock when you'd like to scan the image on your host machine.

Quick Start

Basic

Simply specify an image name (and a tag).

$ dockle [YOUR_IMAGE_NAME]

IGNORE  - CIS-DI-0006: Add HEALTHCHECK instruction to the container image

Docker

Also, you can use Docker to use dockle command as follow.

$ export DOCKLE_LATEST=$(
 curl --silent "https://api.github.com/repos/habakke/dockle/releases/latest" | \
 grep '"tag_name":' | \
 sed -E 's/.*"v([^"]+)".*/\1/' \
)
$ docker run --rm habakke/dockle:v${DOCKLE_LATEST} [YOUR_IMAGE_NAME]

  • If you'd like to scan the image on your host machine, you need to mount docker.sock.

    $ docker run --rm -v /var/run/docker.sock:/var/run/docker.sock ...

Specify exit code

By default, Dockle exits with code 0 even if there are some problems.

Use the --exit-code, -c option to exit with a non-zero exit code if WARN or FATAL alert were found.

$ dockle --exit-code 1 [IMAGE_NAME]

Specify exit level

By default, --exit-code run when there are WARN or FATAL level alerts.

Use the --exit-level, -l option to change alert level. You can set info, warn or fatal.

$ dockle --exit-code 1 --exit-level info [IMAGE_NAME]
$ dockle --exit-code 1 --exit-level fatal [IMAGE_NAME]

Ignore the specified checkpoints

The --ignore, -i option can ignore specified checkpoints.

$ dockle -i CIS-DI-0001 -i DKL-DI-0006 [IMAGE_NAME]

Or, use .dockleignore file.

$ cat .dockleignore
# set root to default user because we want to run nginx
CIS-DI-0001
# Use latest tag because to check the image inside only
DKL-DI-0006

Continuous Integration (CI)

You can scan your built image with Dockle in Travis CI/CircleCI.

In these examples, the test will fail with if any warnings were found.

Though, you can ignore the specified target checkpoints by using .dockleignore file.

Or, if you just want the results to display and not let the test fail for this, specify --exit-code to 0 in dockle command.

Authorization for Private Docker Registry

Dockle can download images from a private registry, without installing Docker or any other 3rd party tools. It's designed so for ease of use in a CI process.

All you have to do is: install Dockle and set ENVIRONMENT variables.

  • NOTE: I don't recommend using ENV vars in your local machine.

Docker Hub

To download the private repository from Docker Hub, you need to set DOCKLE_AUTH_URL, DOCKLE_USERNAME and DOCKLE_PASSWORD ENV vars.

export DOCKLE_AUTH_URL=https://registry.hub.docker.com
export DOCKLE_USERNAME={DOCKERHUB_USERNAME}
export DOCKLE_PASSWORD={DOCKERHUB_PASSWORD}
  • NOTE: You don't need to set ENV vars when downloading from the public repository.

Amazon ECR (Elastic Container Registry)

Dockle uses the AWS SDK. You don't need to install aws CLI tool.

Use AWS CLI's ENVIRONMENT variables.

export AWS_ACCESS_KEY_ID={AWS ACCESS KEY}
export AWS_SECRET_ACCESS_KEY={SECRET KEY}
export AWS_DEFAULT_REGION={AWS REGION}

GCR (Google Container Registry)

Dockle uses the Google Cloud SDK. So, you don't need to install gcloud command.

If you'd like to use the target project's repository, you can settle via GOOGLE_APPLICATION_CREDENTIAL.

# must set DOCKLE_USERNAME empty char
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credential.json

Self Hosted Registry (BasicAuth)
