UCP = Universal Control Plane
DTR = Docker Trusted Registry
DCT = Docker Content Trust
CVE = Common Vulnerabilities and Exposures
PWD = Play With Docker

Prerequisites

This lab requires an instance of Docker Enterprise. Docker Enterprise includes Docker Universal Control Plane and Docker Trusted Registry. This lab provides Docker Enterprise.

Understanding the Play With Docker Interface

This workshop is only available to people in a pre-arranged workshop. That may happen through a Docker Meetup, a conference workshop that is being led by someone who has made these arrangements, or special arrangements between Docker and your company. The workshop leader will provide you with the URL to a workshop environment that includes Docker Enterprise. The environment will be based on Play with Docker.

If none of these apply to you, contact your local Docker Meetup Chapter and ask if there are any scheduled workshops. In the meantime, you may be interested in the labs available through the Play with Docker Classroom.

There are three main components to the Play With Docker (PWD) interface.

1. Console Access

Play with Docker provides access to the 3 Docker Enterprise hosts in your Cluster. These machines are:

A Linux-based Docker Enterprise 2.1 (UCP 3.1.6 & DTR 2.6.5 & 18.09.2) Manager node
Three Linux-based Docker Enterprise 2.1 (18.09.2) Worker nodes

By clicking a name on the left, the console window will be connected to that node.

2. Access to your Universal Control Plane (UCP) and Docker Trusted Registry (DTR) servers

Additionally, the PWD screen provides you with a one-click access to the Universal Control Plane (UCP) web-based management interface as well as the Docker Trusted Registry (DTR) web-based management interface. Clicking on either the UCP or DTR button will bring up the respective server web interface in a new tab.

3. Session Information

Throughout the lab you will be asked to provide either hostnames or login credentials that are unique to your environment. These are displayed for you at the bottom of the screen.

Note: There are a limited number of lab connections available for the day. You can use the same session all day by simply keeping your browser connection to the PWD environment open between sessions. This will help us get as many people connected as possible, and prevent you needing to get new credentials and hostnames in every lab. However, if you do lose your connection between sessions simply go to the PWD URL again and you will be given a new session.

Introduction

This workshop is designed to demonstrate the power of Docker Secrets, Image Promotion, Scanning Engine, and Content Trust. We will walk through creating a few secrets. Deploying a stack that uses the secret. Then we will create a Docker Trusted Registry repository where we can create a promotion policy. The promotion policy leverages the output from Image Scanning result. This is the foundation of creating a Secure Supply Chain. You can read more about secure supply chains for our Secure Supply Chain reference architecture.

Task 1 - Accessing PWD

Navigate in your web browser to the URL the workshop organizer provided to you. Chrome is advised!
Fill out the form, and click submit. You will then be redirected to the PWD environment. It may take a minute or so to provision out your PWD environment.

Task 1.1 - Set Up Environment Variables

We are going to use worker3 for ALL our command line work. Click on worker3 to activate the shell.

Now we need to setup a few variables. We need to create DTR_URL and DTR_USERNAME. But the easiest way is to clone the Workshop Repo and run script.

git clone https://github.com/clemenko/dc19_supply_chain.git

Once cloned, now we can run the var_setup.sh script.

source dc19_supply_chain/scripts/var_setup.sh

Now your PWD environment variables are setup. We will use the variables for some scripting.

Task 2 - Enable Docker Image Scanning

Before we create the repositories, let's start with enabling the Docker Image Scanning engine.

From the main PWD screen click the DTR button on the left side of the screen

Note: Because this is a lab-based install of Docker Enterprise we are using the default self-signed certs. Because of this your browser may display a security warning. It is safe to click through this warning.

In a production environment you would use certs from a trusted certificate authority and would not see this screen.
Navigate to System on the left pane, then Security.
Select Enable Scanning. Leave it in Online mode and select Enable. Press the button Enable Online Scanning. The CVE database will start downloading. This can take a few minutes. Please be patient for it to complete.

Task 3 - Create Jenkins User and Organization

In order to setup our automation we need to create an organization and a user account for Jenkins. We are going to create a user named jenkins in the organization ci.

Task 3.1 - Create Jenkins Organization

From the PWD main page click on DTR.
Once in DTR navigate to Organizations on the left.
Now click New organization.
Type in ci and click Save.

Now we should see the organization named ci.

Task 3.2 - Create Jenkins User

While remaining in DTR we can create the user from here.

Click on the organization ci.
Click Add user.
Make sure you click the radio button New. Add a new user name jenkins. Set a simple password that you can remember. Maybe admin1234?

Now change the permissions for the jenkins account to Org Owner.

Task 3.3 - Create Jenkins DTR Token

Now that we have the jenkins user created we need to add a token for use with DTR's API.

Navigate to Users on the left pane. Click on jenkins, then click the Access Tokens tab.

Click New access token. Enter Supply Chain into the description field and click Create.

Write down the token that is displayed. You will need this again!

It should look like ee9d7ff2-6fd4-4a41-9971-789e06e0d5d5. Click Done.

Lets add it to the worker3 environment. Replace <TOKEN> with the token from DTR.

#example
#export DTR_TOKEN=ee9d7ff2-6fd4-4a41-9971-789e06e0d5d5
export DTR_TOKEN=<TOKEN>

Task 4 - Create DTR Repositories

We now need to access Docker Trusted Registry to setup two repositories.

We have an easy way with a script or the hard way by using the GUI.

Either way we need to create two repositories, dc19_build and dc19. dc19_build will be used for the private version of the image. dc19 will be the public version once an CVE scan is complete.

Easy Way:

Since we used git clone to copy the repository to worker3 for this workshop, there is a script from that will create the DTR repositories.

./dc19_supply_chain/scripts/create_repos.sh

Feel free to cat the file to see how we are using curl and the API to create the repositories.

[worker3] (local) [email protected] ~
$ cat dc19_supply_chain/scripts/create_repos.sh
#!/bin/bash
# requires environment variables: DTR_HOST, DTR_USERNAME and DTR_TOKEN

if [ -z "$DTR_TOKEN" ]; then
  echo " Please create a DTR_TOKEN variable before preceding..."
  exit
fi

curl -X POST -k -L \
  -u $DTR_USERNAME:$DTR_TOKEN \
  https://$DTR_URL/api/v0/repositories/ci \
  -H 'Content-Type: application/json' \
  -d '{
  "enableManifestLists": true,
  "immutableTags": true,
  "longDescription": "",
  "name": "dc19",
  "scanOnPush": true,
  "shortDescription": "Dockercon 2019 Example - public",
  "visibility": "public"
}'

curl -X POST -k -L \
  -u $DTR_USERNAME:$DTR_TOKEN \
  https://$DTR_URL/api/v0/repositories/ci \
  -H 'Content-Type: application/json' \
  -d '{
  "enableManifestLists": true,
  "immutableTags": true,
  "longDescription": "",
  "name": "dc19_build",
  "scanOnPush": true,
  "shortDescription": "Dockercon 2019 Example - private",
  "visibility": "public"
}'

Hard Way:

Navigate to Repositories on the left menu and click New repository.
Create that looks like ci/dc19_build. Make sure you click Private. Do not click Create yet!
Click Show advanced settings and then click On Push under SCAN ON PUSH. This will ensure that the CVE scan will start right after every push to this repository. And turn on IMMUTABILITY. Then click Create.
Repeat this for creating the ci/dc19 Public repository with SCAN ON PUSH set to On Push and IMMUTABILITY turned Off.
We should have two repositories now.

Task 4.1 - Create Promotion Policy - Private to Public

With the two repositories setup we can now define the promotion policy. The first policy we are going to create is for promoting an image that has passed a scan with zero (0) Critical vulnerabilities. The policy will target the ci/dc19 repository.

Navigate to the ci/dc19_build repository. Click Promotions and click New promotion policy. Note: Make sure the Is source box is selected.
In the PROMOTE TO TARGET IF... box select Critical Vulnerabilities and then check less than or equals. In the box below equals enter the number zero (4) and click Add.
Set the TARGET REPOSITORY to ci/dc19 and click Save & Apply.

When we push an image to ci/dc19_build it will get scanned. Based on that scan report we could see the image moved to ci/dc19. Lets push a few images to see if it worked.

Task 5 - Pull / Tag / Push Docker Image

Lets pull, tag, and push a few images to YOUR DTR.

In order to push and pull images to DTR we will need to take advantage of PWD's Console Access.

Navigate back to the PWD tab in your browser.
Click on worker3.
In the console we should already have a variable called DTR_URL. Lets check.
```
echo $DTR_URL
```
If you are not sure please follow Task 1.1 Set Up Environment Variables.
Now we login to our DTR server using your DTR_TOKEN from Task 3.3 Create Jenkins DTR Token.
```
docker login -u jenkins -p $DTR_TOKEN $DTR_URL
```

Now we can start pulling a few images.

docker pull clemenko/dc19:0.1
docker pull clemenko/dc19:0.2
docker pull clemenko/dc19:0.3
docker pull alpine

This command is pull a few images from hub.docker.com.

Now let's tag the image for our DTR instance. We will use the URL variable we set before.

docker tag clemenko/dc19:0.1 $DTR_URL/ci/dc19_build:0.1
docker tag clemenko/dc19:0.2 $DTR_URL/ci/dc19_build:0.2
docker tag clemenko/dc19:0.3 $DTR_URL/ci/dc19_build:0.3
docker tag alpine $DTR_URL/ci/dc19_build:alpine

Now we can docker push the images to DTR.

docker push $DTR_URL/ci/dc19_build:0.1
docker push $DTR_URL/ci/dc19_build:0.2
docker push $DTR_URL/ci/dc19_build:0.3
docker push $DTR_URL/ci/dc19_build:alpine

Task 6 - Review Scan Results

Lets take a good look at the scan results from the images. Please keep in mind this will take a few minutes to complete.

Navigate to DTR --> Repositories --> ci/dc19_build --> Tags.

Don't worry if you see images in a Scanning... or Pending state. Please click to another tab and click back.
Take a look at the details to see exactly what piece of the image is vulnerable.

Click View details for an image that has vulnerabilities. How about 0.2? There are two views for the scanning results, Layers and Components. The Layers view shows which layer of the image had the vulnerable binary. This is extremely useful when diagnosing where the vulnerability is in the Dockerfile.

The vulnerable binary is displayed, along with all the other contents of the layer, when you click the layer itself. In this example there are a few potentially vulnerable binaries:

Now we have a chance to review each vulnerability by clicking the CVE itself, example CVE-2019-3822. This will direct you to Mitre's site for CVEs.

Now that we know what is in the image. We should probably act upon it.

Task 6.1 - Hide Vulnerabilities

If we find that they CVE is a false positive. Meaning that it might be disputed, or from OS that you are not using. If this is the case we can simply Hide the vulnerability. This will not remove the fact that the CVE was found.

Click Show layers affected and then you can click Hide for the one critical CVE.

If we click back to Tags we can now see that the image does not have a critical vulnerability.

Once we have hidden some CVEs we might want to perform a manual promotion of the image.

Task 7 - Extend with Image Mirroring

Docker Trusted Registry allows you to create mirroring policies for a repository. When an image gets pushed to a repository and meets a certain criteria, DTR automatically pushes it to repository in another DTR deployment or Docker Hub.

This not only allows you to mirror images but also allows you to create image promotion pipelines that span multiple DTR deployments and datacenters. Let's set one up. How about we mirror an image to hub.docker.com?

Go to hub.docker.com and create an login and repository.
Navigate to Repositories --> ci/dc19 --> MIRRORS --> New mirror. Change the REGISTRY TYPE to Docker Hub and fill out the relevant information like:
Click Connect and scroll down.
Next create a tag name Trigger that is equal to promoted
Leave the %n tag renaming the same.
Click Save & Apply.

Since we already had an image that had the tag promoted we should see that the image was pushed to hub.docker.com. In fact we can click on the hub repository name to see if the image push was successful.

Task 8 - Docker Content Trust / Image Signing

Docker Content Trust/Notary provides a cryptographic signature for each image. The signature provides security so that the image requested is the image you get. Read Notary's Architecture to learn more about how Notary is secure. Since Docker Enterprise is "Secure by Default," Docker Trusted Registry comes with the Notary server out of the box.

We can create policy enforcement within Universal Control Plane (UCP) such that ONLY signed images from the ci team will be allowed to run. Since this workshop is about DTR and Secure Supply Chain we will skip that step.

Let's sign your first Docker image?

Right now you should have a promoted image $DTR_URL/ci/dc19:0.2. We need to tag it with a new signed tag.
```
docker pull $DTR_URL/ci/dc19:0.2
docker tag $DTR_URL/ci/dc19:0.2 $DTR_URL/ci/dc19:signed
```

Now lets use the Trust command... It will ask you for a BUNCH of passwords. Do yourself a favor in this workshop and use admin1234. :D

docker trust sign $DTR_URL/ci/dc19:signed

Here is an example output:

[worker3] (local) [email protected] ~
$ docker trust sign $DTR_URL/ci/dc19:signed
You are about to create a new root signing key passphrase. This passphrase
will be used to protect the most sensitive key in your signing system. Please
choose a long, complex passphrase and be careful to keep the password and the
key file itself secure and backed up. It is highly recommended that you use a
password manager to generate the passphrase and keep it safe. There will be no
way to recover this key. You can find the key in your config directory.
Enter passphrase for new root key with ID b975982:
Repeat passphrase for new root key with ID b975982:
Enter passphrase for new repository key with ID 61a14ae:

[worker3] (local) [email protected] ~

Again please use the same password. It will simplify this part of the workshop.

And we can confirm the signature has been applied by inspecting the image:

docker trust inspect $DTR_URL/ci/dc19:signed

Here is the example output:

[worker3] (local) [email protected] ~
$ docker trust inspect $DTR_URL/ci/dc19:signed
[

                  }
              ]
          }
      ]
  }
]
[worker3] (local) [email protected] ~

Back in DTR, Navigate to Repositories --> ci/dc19 --> Tags and you will now see the new signed tag with the text Signed under the Signed column:
If you were to enable Docker Content Trust in UCP then you would need to upload the public certificate used to sign the image. As we did not perform the docker trust signer add command before step 2 above then a public certificate is automatically generated but is not associated to a user in UCP. This means when UCP tries to verify the signature on a signed image to a user it will fail and therefor not meet UCP's Content Trust policy.

To resolve this issue you can upload the base64 encoded public certificate in ~/.docker/trust/tuf/$DTR_URL/ci/dc19/metadata/targets.json - the certificate is located in the structure .signed.delegations.keys with the key value of public.

For example, use the command cat ~/.docker/trust/tuf/$DTR_URL/ci/dc19/metadata/targets.json | jq '.signed.delegations.keys' | grep public to extract the certificate.

Task 9 - Automate with Jenkins

In order to automate we need to deploy Jenkins. If you want I can point you to a few Docker Compose yamls. OR we have the easy way. The easy, aka script, deploys Jenkins quickly.

Task 9.1 - Deploy Jenkins

Take a look at the script. Also notice the script will check variables, and then runs docker run.
```
cat ./dc19_supply_chain/scripts/jenkins.sh
```
Then run unset Docker Content Trust and instal Jenkins.
```
./dc19_supply_chain/scripts/jenkins.sh
```

Pay attention to the url AND Jenkins password. It will look like :

[worker3] (local) [email protected] ~/
$ dc19_supply_chain/scripts/jenkins.sh
=========================================================================================================

  Jenkins URL : http://ip172-18-0-20-bcelih5dffhg00b2thog.direct.ee-beta2.play-with-docker.com:8080

=========================================================================================================
  Waiting for Jenkins to start................
=========================================================================================================

  Jenkins Setup Password = d32eda1cf2464b818826fd82b4f7c2cb

=========================================================================================================

Now navigate to http://$DOCS_URL:8080 by clicking on the url in the terminal. Let's start the setup of Jenkins and enter the password. It may take a minute or two for the Unlock Jenkins page to load. Be patient.
Click Select plugins to install.
We don't need to install all plugins at this point. Click none at the top.
Next Click Continue as admin in the lower right hand corner. We don't need to create another username for Jenkins.
Next for Instance Configuration click Save and Finish.
And we are done installing Jenkins. Click Start using Jenkins

Task 9.2 - Plumb Jenkins

Now that we have Jenkins setup and running we need to add 3 additional plugins - Blue Ocean, Generic Webhook Trigger and Pipeline:

Click on Manage Jenkins --> Manage Plugins --> Available and filter/search for Blue Ocean, Generic Webhook Trigger and Pipeline. When you have found each one check the checkbox to the left of the plugin name to select for installation.
Click on Install without restart and wait for the plugins to install. When all plugins have installed navigate back to the Jenkins homepage.
Click on New item in the upper left.
Enter a name like ci_dc19, click Freestyle project and then click OK.
Let's scroll down to the Build section. We will come back to the Build Triggers section in a bit. Now click Add build step --> Execute shell.

You will now see a text box. Past the following build script into the text box.

Please replace the <DTR_URL> with your URL! echo $DTR_URL <-- worker3

DTR_USERNAME=admin
DTR_URL=<DTR_URL>

docker login -u admin -p admin1234 $DTR_URL

docker pull clemenko/dc19:0.2

docker tag clemenko/dc19:0.2 $DTR_URL/ci/dc19_build:jenkins_$BUILD_NUMBER

docker push $DTR_URL/ci/dc19_build:jenkins_$BUILD_NUMBER

docker rmi clemenko/dc19:0.2 $DTR_URL/ci/dc19_build:jenkins_$BUILD_NUMBER

It will look very similar to:

Now scroll down and click Save.

Now let's run the build. Click Build now.
You can watch the output of the Build by clicking on the task number in the Build History and then selecting Build Output
The console output will show you all the details from the script execution.
Review the ci/dc19 repository in DTR. You should now see a bunch of tags that have been promoted.

Task 9.3 - Webhooks

Now that we have Jenkins setup we can extend with webhooks. In Jenkins speak a webhook is simply a build trigger. Let's configure one.

Navigate to Jenkins and click on the project/item called ci_dc19 and click on Configure on the left hand side.
Then scroll down to Build Triggers. Check the checkbox for Trigger builds remotely and enter a Token of dc19_rocks. Scroll down and click Save.
Now in your browser goto YOUR http://$DOCS_URL:8080/job/ci_dc19/build?token=dc19_rocks

It should look like: http://ip172-18-0-9-bis91vft0fgg00ctq3i0.direct.ee-beta2.play-with-docker.com:8080/job/ci_dc19/build?token=dc19_rocks
Check DTR to verify the images were pushed. Then log into https:hub.docker.com to see if your images were mirrored.

Conclusion

In this workshop we were able use the tools that are included with Docker Trusted Registry to build a basic Automated Secure Supply Chain. Hopefully with this foundation you can build your own organizations Secure Supply Chain!
