You can configure Harbor to connect to an email server, set the registry in read-only mode, and configure Harbor so that only system administrators can create projects.
|
|
|
|
## Configure an Email Server
|
|
|
|
You can configure Harbor to connect to an email server. The email server is only used to send out responses to users who request to reset their password.
|
|
|
|
|
|
|
|
## Make the Registry Read Only
|
|
|
|
You can set Harbor to read-only mode. In read-only mode, Harbor allows `docker pull` but prevents `docker push` and the deletion of repositories and tags.
|
|
|
|
|
|
|
|
If it set to true, deleting repositories, tags and pushing images are not permitted.
|
|
|
|
|
|
|
|
```sh
|
|
docker push 10.117.169.182/demo/ubuntu:14.04
|
|
The push refers to a repository [10.117.169.182/demo/ubuntu]
|
|
0271b8eebde3: Preparing
|
|
denied: The system is in read only mode. Any modification is prohibited.
|
|
```
|
|
|
|
## Set Who Can Create Projects
|
|
|
|
Use the **Project Creation** drop-down menu to set which users can create projects. Select **Everyone** to allow all users to create projects. Select **Admin Only** to allow only users with the Harbor system administrator role to create projects.
