BasicAuth
Adding Basic Authentication {: .subtitle }
The BasicAuth middleware restricts access to your services to known users.
Configuration Examples
# Declaring the user list
#
# Note: when used in docker-compose.yml all dollar signs in the hash need to be doubled for escaping.
# To create user:password pair, it's possible to use this command:
# echo $(htpasswd -nB user) | sed -e s/\\$/\\$\\$/g
#
# Also note that dollar signs should NOT be doubled when they not evaluated (e.g. Ansible docker_container module).

Configuration Options
General
Passwords must be hashed using MD5, SHA1, or BCrypt.
!!! tip
Use `htpasswd` to generate the passwords.
users
The users
option is an array of authorized users. Each user must be declared using the name:hashed-password
format.
!!! note ""
- 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.
# Declaring the user list
#
# Note: all dollar signs in the hash need to be doubled for escaping.
# To create a user:password pair, the following command can be used:
# echo $(htpasswd -nb user password) | sed -e s/\\$/\\$\\$/g

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:hashed-password
.
!!! note ""
- 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.
