DigestAuth

Adding Digest Authentication

The DigestAuth middleware grants access to services to authorized users only.

Configuration Examples

Configuration Options

Tip

Use htdigest to generate passwords.

users

The users option is an array of authorized users. Each user will be declared using the name:realm:encoded-password format.

• If both users and usersFile are provided, the two are merged. The contents of usersFile have precedence over the values in users.
• For security reasons, the field users doesn’t exist for Kubernetes IngressRoute, and one should use the secret field instead.

    ]

usersFile

The usersFile option is the path to an external file that contains the authorized users for the middleware.

The file content is a list of name:realm:encoded-password.

• If both users and usersFile are provided, the two are merged. The contents of usersFile have precedence over the values in users.
• Because it does not make much sense to refer to a file path on Kubernetes, the usersFile field doesn’t exist for Kubernetes IngressRoute, and one should use the secret field instead.
