Configuring Docker Notary and Docker Client
There is no configuration needed in Artifactory in order to work with trusted Docker images. However, in the setup instructions below, we do recommend testing your configuration by signing Artifactory and running it in a container.
To configure the Docker Notary and client to work with Artifactory, execute the following main steps:
Configuring Your Hosts File
If you are not working with a DNS, add the following entries to your
sudo sh -c 'echo "<Host IP> <Notary Server Name>" >> /etc/hosts'
sudo sh -c 'echo "<Host IP> <Artifactory Server Name>" >> /etc/hosts'
Configuring the Notary Server
Create a directory for your Notary server. In the code snippets below we will use
Create a dockerfile with the following content:
ADD https://get.docker.com/builds/Linux/x86_64/docker-1.9.1 /usr/bin/docker
RUN chmod +x /usr/bin/docker \
&& apt-get update \
&& apt-get install -y \
RUN git clone https://github.com/docker/notary.git && \
cp /root/notary/fixtures/root-ca.crt /usr/local/share/ca-certificates/root-ca.crt && \
Use a private certificate
This configuration runs with a public certificate. Any Docker client running with the same public certificate may be able to access your Notary server.
For a secure setup, we recommend replacing it with your organization's private certificate by replacing the public
root-ca.crt certificate file
with your private certificate under
/root/notary/fixtures on your Notary server, and under
/usr/local/share/ca-certificates on the machine running your Docker client.
Build the test image:
docker build -t [image name] [path to dockerfile]
If you are running the build in your dockerfile directory, you can just use "." as the path to the dockerfile
Start the Notary server:
To start the Notary server, you first need to have
Docker Compose installed.
Then execute the following steps:
git clone -b trust-sandbox https://github.com/docker/notary.git
docker-compose up -d
Configuring the Docker Client
To connect the Notary server to the Docker client you need to enable the Docker content trust flag and add the Notary server URL as follows:
Test Your Setup
The example below demonstrates setting up the Notary server and Docker client, signing an image and the pushing it to Artifactory, with the following assumptions:
Set up the IP mappings
sudo sh -c 'echo "127.0.0.1 notaryserver" >> /etc/hosts'
sudo sh -c 'echo "127.0.0.1 artifactory-registry" >> /etc/hosts'
Pull an image for testing
docker pull docker/trusttest
After you have pulled the image, you need to
docker login to
Configure the Docker client
Tag the image you pulled for testing and push it to Artifactory
docker tag docker/trusttest artifactory-registry:5002/test/trusttest:latest
docker push artifactory-registry:5002/test/trusttest:latest
You will be asked to enter the root key passphrase. This will be needed every time you push a new image while the DOCKER_CONTENT_TRUST flag is set.
The root key is generated at:
You will also be asked to enter a new passphrase for the image. This is generated at
/root/.docker/trust/private/tuf_keys/[registry name] /[imagepath]
The Docker image is signed after it is
pushed to Artifactory.
