You interact with Mirantis Secure Registry in the same way you interact with Docker Hub or any other registry:
docker login <msr-url>
: authenticates you on MSRdocker pull <image>:<tag>
: pulls an image from MSRdocker push <image>:<tag>
: pushes an image to MSRPulling an image from Mirantis Secure Registry is the same as pulling an image from Docker Hub or any other registry. Since MSR is secure by default, you always need to authenticate before pulling images.
In this example, MSR can be accessed at dtr-example.com
, and the user was
granted permissions to access the nginx
and wordpress
repositories in the library
organization.
Click on the repository name to see its details.
To pull the latest tag of the library/wordpress
image, run:
docker login dtr-example.com
docker pull dtr-example.com/library/wordpress:latest
Before you can push an image to MSR, you need to create a
repository to store the image. In this example the full
name of our repository is dtr-example.com/library/wordpress
.
In this example we’ll pull the wordpress image from Docker Hub and tag with the full MSR and repository name. A tag defines where the image was pulled from, and where it will be pushed to.
# Pull from Docker Hub the latest tag of the wordpress image
docker pull wordpress:latest
# Tag the wordpress:latest image with the full repository name we've created in MSR
docker tag wordpress:latest dtr-example.com/library/wordpress:latest
Now that you have tagged the image, you only need to authenticate and push the image to MSR.
docker login dtr-example.com
docker push dtr-example.com/library/wordpress:latest
On the web interface, navigate to the Tags tab on the repository page to confirm that the tag was successfully pushed.
The base layers of the Microsoft Windows base images have restrictions on how they can be redistributed. When you push a Windows image to MSR, Docker only pushes the image manifest and all the layers on top of the Windows base layers. The Windows base layers are not pushed to MSR. This means that:
This default behavior is recommended for Mirantis Container Runtime installations, but for air-gapped or similarly limited setups Docker can optionally optionally also push the Windows base layers to MSR.
To configure Docker to always push Windows layers to MSR, add the
following to your C:\ProgramData\docker\config\daemon.json
configuration file:
"allow-nondistributable-artifacts": ["<msr-domain>:<msr-port>"]
