Finally, install Docker: sudo apt install docker-ce Docker should now be installed, the daemon started, and the process enabled to start on boot. Check that it’s running: sudo systemctl status docker The output should be similar to the following, showing that the service is active and running. Docker Registry.

Later in this tutorial, you’ll learn how to push an image to a Docker registry like Docker Hub so that it may be assessed and used by you and others.

While it’s highly recommended to secure your registry using a TLS certificateissued by a known CA, you can choose to use self-signed certificates, or useyour registry over an unencrypted HTTP connection. Either of these choicesinvolves security trade-offs and additional configuration steps.

Deploy a plain HTTP registry

Warning:It’s not possible to use an insecure registry with basic authentication.

This procedure configures Docker to entirely disregard security for yourregistry. This is very insecure and is not recommended. It exposes yourregistry to trivial man-in-the-middle (MITM) attacks. Only use this solution forisolated testing or in a tightly controlled, air-gapped environment.

Edit the daemon.json file, whose default location is/etc/docker/daemon.json on Linux orC:ProgramDatadockerconfigdaemon.json on Windows Server. If you useDocker Desktop for Mac or Docker Desktop for Windows, click the Docker icon, choosePreferences (Mac) or Settings (Windows), and choose Docker Engine.
If the daemon.json file does not exist, create it. Assuming there are noother settings in the file, it should have the following contents:
Substitute the address of your insecure registry for the one in the example.
With insecure registries enabled, Docker goes through the following steps:
- First, try using HTTPS.
  - If HTTPS is available but the certificate is invalid, ignore the errorabout the certificate.
  - If HTTPS is not available, fall back to HTTP.
Restart Docker for the changes to take effect.

Repeat these steps on every Engine host that wants to access your registry.

Use self-signed certificates

Warning:Using this along with basic authentication requires to also trust the certificate into the OS cert store for some versions of docker (see below)

This is more secure than the insecure registry solution.

Generate your own certificate:
Be sure to use the name myregistrydomain.com as a CN.
Use the result to start your registry with TLS enabled.
Instruct every Docker daemon to trust that certificate. The way to do thisdepends on your OS.
- Linux: Copy the domain.crt file to/etc/docker/certs.d/myregistrydomain.com:5000/ca.crt on every Dockerhost. You do not need to restart Docker.
- Windows Server:
  1. Open Windows Explorer, right-click the domain.crtfile, and choose Install certificate. When prompted, select the followingoptions:
    Store location local machine
    Place all certificates in the following store selected
  2. Click Browser and select Trusted Root Certificate Authorities.
  3. Click Finish. Restart Docker.
- Docker Desktop for Mac: Follow the instructions inAdding custom CA certificates.Restart Docker.
- Docker Desktop for Windows: Follow the instructions inAdding custom CA certificates.Restart Docker.

Troubleshoot insecure registry

This section lists some common failures and how to recover from them.

Failing...

Failing to configure the Engine daemon and trying to pull from a registry that is not usingTLS results in the following message:

Docker still complains about the certificate when using authentication?

When using authentication, some versions of Docker also require you to trust thecertificate at the OS level.

Ubuntu

Red Hat Enterprise Linux

Oracle Linux

Restart Docker for the changes to take effect.

Windows

Open Windows Explorer, right-click the certificate, and chooseInstall certificate.

Then, select the following options:

Store location: local machine
Check place all certificates in the following store
Click Browser, and select Trusted Root Certificate Authorities
Click Finish

After adding the CA certificate to Windows, restart Docker Desktop for Windows.

What it is

The Registry is a stateless, highly scalable server side application that storesand lets you distribute Docker images. The Registry is open-source, under thepermissive Apache license.

Why use it

You should use the Registry if you want to:

tightly control where your images are being stored
fully own your images distribution pipeline
integrate image storage and distribution tightly into your in-house development workflow

Alternatives

Users looking for a zero maintenance, ready-to-go solution are encouraged tohead-over to the Docker Hub, which provides afree-to-use, hosted Registry, plus additional features (organization accounts,automated builds, and more).

Requirements

The Registry is compatible with Docker engine version 1.6.0 or higher.

Basic commands

Start your registry

Pull (or build) some image from the hub

Tag the image so that it points to your registry
