|
An enterprise platform for managing Kubernetes Everywhere
|
|
Rancher is a platform built to address the needs of the DevOps teams deploying applications with Kubernetes, and the IT staff responsible for delivering an enterprise-critical service.
|
|

|
|
|
|
## Preparation
|
|
|
|
The following placeholders will be used:
|
|
|
|
- `rancher.company` is the FQDN of the Rancher install.
|
|
- `authentik.company` is the FQDN of the authentik install.
|
|
|
|
Under *Property Mappings*, create a *SAML Property Mapping*. Give it a name like "SAML Rancher User ID". Set the SAML name to `rancherUidUsername` and the expression to the following
|
|
|
|
```python
|
|
return f"{user.pk}-{user.username}"
|
|
```
|
|
|
|
Create an application in authentik. Create a SAML provider with the following parameters:
|
|
|
|
- ACS URL: `https://rancher.company/v1-saml/adfs/saml/acs`
|
|
- Audience: `https://rancher.company/v1-saml/adfs/saml/metadata`
|
|
- Issuer: `authentik`
|
|
- Service Provider Binding: `Post`
|
|
- Property mappings: Select all default mappings and the mapping you've created above.
|
|
- Signing Certificate: Select the authentik self-signed certificate.
|
|
|
|
You can of course use a custom signing certificate, and adjust durations.
|
|
|
|
## Rancher
|
|
|
|
In Rancher, navigate to *Global* -> *Security* -> *Authentication*, and select ADFS.
|
|
|
|
Fill in the fields
|
|
|
|
- Display Name Field: `http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name`
|
|
- User Name Field: `http://schemas.goauthentik.io/2021/02/saml/username`
|
|
- UID Field: `rancherUidUsername`
|
|
- Groups Field: `http://schemas.xmlsoap.org/claims/Group`
|
|
|
|
For the private key and certificate, you can either generate a new pair (in authentik, navigate to *Identity & Cryptography* -> *Certificates* and select Generate), or use an existing pair.
|
|
|
|
Copy the metadata from authentik, and paste it in the metadata field.
|
|
|
|
Click on save to test the authentication.
