# Implementing Content Trust
|
|
**NOTE: Notary is an optional component, please make sure you have already installed it in your Harbor instance before you go through this section.**
|
|
If you want to enable content trust to ensure that images are signed, please set two environment variables in the command line before pushing or pulling any image:
|
|
```sh
|
|
export DOCKER_CONTENT_TRUST=1
|
|
export DOCKER_CONTENT_TRUST_SERVER=https://10.117.169.182:4443
|
|
```
|
|
If you push the image for the first time, 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: ``/root/.docker/trust/private/root_keys``
|
|
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]``.
|
|
If you are using a self-signed cert, make sure to copy the CA cert into ```/etc/docker/certs.d/10.117.169.182``` and ```$HOME/.docker/tls/10.117.169.182:4443/```. When an image is signed, it is indicated in the Web UI.
|
|
**Note: Replace "10.117.169.182" with the IP address or domain name of your Harbor node. In order to use content trust, HTTPS must be enabled in Harbor.**
|
|
|
|
|
|
When an image is signed, it has a tick shown in UI; otherwise, a cross sign(X) is displayed instead.
