Usage

Enabling HTTP Auth

The http-auth:enable command can be used to enable HTTP Auth for an app.

dokku http-auth:enable node-js-app

-----> Enabling HTTP auth for node-js-app...
 !     Skipping user initialization
-----> Configuring node-js-app.dokku.me...(using built-in template)
-----> Creating https nginx.conf
       Enabling HSTS
       Reloading nginx
       Done

A user/password combination can also be specified when enabling HTTP Auth.

dokku http-auth:enable node-js-app username password

-----> Enabling HTTP auth for node-js-app...
-----> Configuring node-js-app.dokku.me...(using built-in template)
-----> Creating https nginx.conf
       Enabling HSTS
       Reloading nginx
       Done

Adding users

Individual user/password combinations can be added at any point in time via the http-auth:add-user command. Specifying the same user twice will override the first instance of the user, even if the password is the same.

dokku http-auth:add-user node-js-app username password

-----> Adding username to basic auth list
-----> Configuring node-js-app.dokku.me...(using built-in template)
-----> Creating https nginx.conf
       Enabling HSTS
       Reloading nginx

Removing users

A user can be removed via the http-auth:remove-user command. This command will always reload nginx, even if the user does not exist.

dokku http-auth:remove-user node-js-app username

-----> Removing username from basic auth list
-----> Configuring node-js-app.dokku.me...(using built-in template)
-----> Creating https nginx.conf
       Enabling HSTS
       Reloading nginx

Limiting access to specific IP Addresses

See the Nginx Documentation for more information on how this works

Access can be allowed to only a specified set of IP Addresses, CIDR Blocks, or UNIX-domain sockets via the http-auth:add-allowed-ip command. This is used in conjunction with the basic auth support.

dokku http-auth:add-allowed-ip node-js-app 127.0.0.1

-----> Adding 127.0.0.1 to allowed ip list
-----> Ensuring network configuration is in sync for node-js-app
-----> Configuring node-js-app.dokku.me...(using built-in template)
-----> Creating https nginx.conf
       Enabling HSTS
       Reloading nginx

The specified IP address can be removed via the http-auth:remove-allowed-ip command.

dokku http-auth:remove-allowed-ip node-js-app 127.0.0.1

-----> Removing 127.0.0.1 from allowed ip list
-----> Ensuring network configuration is in sync for node-js-app
-----> Configuring node-js-app.dokku.me...(using built-in template)
-----> Creating https nginx.conf
       Enabling HSTS
       Reloading nginx

Viewing http auth config

The nginx http-auth.conf file can be viewed via the http-auth:show-config command. This command will not output the htaccess file.

dokku http-auth:show-config node-js-app username

auth_basic           "Restricted";
auth_basic_user_file /home/dokku/node-js-app/htpasswd;

Displaying http auth reports for an app

You can get a report about the app’s http-auth status using the http-auth:report command:

# dokku http-auth:report node-js-app

=====> node-js-app http-auth information
       Http auth enabled:             true
       Http auth allowed ips:         127.0.0.1
       Http auth users:               root username

You can pass flags which will output only the value of the specific information you want. For example:

dokku http-auth:report node-js-app --http-auth-enabled
