Tracking container vulnerabilities with Clair Control

Clairctl is a lightweight command-line tool doing the bridge between Registries as Docker Hub, Docker Registry or Quay.io, and the CoreOS vulnerability tracker, Clair. Clairctl will play as reverse proxy for authentication.

Clairctl version is align with the CoreOS Clair supported version.

Go to Release and download your corresponding version

curl -L https://raw.githubusercontent.com/jgsqware/clairctl/master/install.sh | sh

$ git clone [email protected]:jgsqware/clairctl.git $GOPATH/src/github.com/jgsqware/clairctl
$ cd $GOPATH/src/github.com/jgsqware/clairctl
$ docker-compose up -d postgres
Creating network "clairctl_default" with the default driver
Creating clairctl_postgres_1 ...
Creating clairctl_clair_1 ...
Creating clairctl_clairctl_1 ...

The above commands will check out the clairctl repo and start the complete postgres/clair/clairctl stack.

$ docker-compose exec clairctl clairctl health

Clair: ✔

The above command will make sure clairctl can reach clair.

If you wish to serve local images to clair, the user inside the clairctl container will need read access to /var/run/docker.sock.

Give the user access by:

• Running the container as root (--user root with docker run or user: root with docker-compose)
• Add the container user to the docker group (----group-add group_id with docker run or group_add: group_id with docker-compose)

To get the group name or id, simply execute :

$ docker-compose exec clairctl ls -alh /var/run/docker.sock
srw-rw----    1 root     50             0 Jul 18 09:48 /var/run/docker.sock

In the example above, 50 is the required group.

clairctl get vulnerabilities report from Clair and generate HTML report

clairctl can be used for Docker Hub and self-hosted Registry

Analyze your docker image with Clair, directly from your registry.

Usage:
  clairctl [command]

Available Commands:
  analyze     Analyze Docker image
  health      Get Health of clairctl and underlying services
  pull        Pull Docker image information (This will not pull the image !)
  push        Push Docker image to Clair
  report      Generate Docker Image vulnerabilities report
  version     Get Versions of clairctl and underlying services

Flags:
      --config string      config file (default is ./.clairctl.yml)
      --log-level string   log level [Panic,Fatal,Error,Warn,Info,Debug]

Use "clairctl [command] --help" for more information about a command.

clair:
  port: 6060
  healthPort: 6061
  uri: http://clair
  report:
    path: ./reports
    format: html

This is an example yaml file. You can have an empty file or a mix with only generalwhitelist or images.

generalwhitelist: #Approve CVE for any image
  CVE-2016-2148: BusyBox
  CVE-2014-8625: Why is it whitelisted
images:
  ubuntu: #Approve CVE only for ubuntu image, regardless of the version
    CVE-2014-2667: Python
    CVE-2017-5230: Something
  alpine:
    CVE-2016-7068: Something

clairctl requires Go 1.8+.

Install Glide:

curl https://glide.sh/get | sh

Clone and build:

git clone [email protected]:jgsqware/clairctl.git $GOPATH/src/github.com/jgsqware/clairctl
cd $GOPATH/src/github.com/jgsqware/clairctl
glide install -v
go get -u github.com/jteeuwen/go-bindata/...
go generate ./clair
go build

This will result in a clairctl executable in the $GOPATH/src/github.com/jgsqware/clairctl folder.

If you get 400 errors, check out clair's logs. The usual reasons are :

• You are serving a local image, and clair cannot connect to clairctl.
• You are trying to analyze an official image from docker hub and you have not done a docker login first.

Please try these two things before opening an Issue.

If you are running the stack with the provided docker-compose.yml, don't forget to grant the user from the clairctl container access to /var/run/docker.sock.

All steps are detailed in the Docker-compose section above.
