File based

StackState Self-hosted v5.1.x

Overview

In case no external authentication provider can be used, you can use file based authentication. This will require every StackState user to be pre-configured in the configuration file. For every change made to a user in the configuration, StackState must be restarted.

StackState includes four default roles - Administrator, Platform Administrator, Power user and Guest. The permissions assigned to each default role and instructions on how to create other roles can be found in the RBAC documentation.

Set up file based authentication

Kubernetes

To configure file based authentication on Kubernetes, StackState users need to be added to the authentication.yaml file. For example:

authentication.yaml

# Four users, `admin`, `platformAdmin`, `power-user` and `guest`
# with the four default roles Administrator, Platform Administrator, Power user and Guest

stackstate:
  authentication:
    file:
      logins:
        - username: admin
          passwordHash: 5f4dcc3b5aa765d61d8327deb882cf99
          roles: [ stackstate-admin ]
        - username: platformadmin
          passwordHash: 5f4dcc3b5aa765d61d8327deb882cf99
          roles: [ stackstate-platform-admin ]
        - username: guest
          passwordHash: 5f4dcc3b5aa765d61d8327deb882cf99
          roles: [ stackstate-guest ]
        - username: power-user
          passwordHash: 5f4dcc3b5aa765d61d8327deb882cf99
          roles: [ stackstate-power-user ]

Follow the steps below to configure users and apply changes:

1. In authentication.yaml - add users. The following configuration should be added for each user (see the example above):

   • username - the username used to log into StackState.

   • passwordHash - the password used to log into StackState. Passwords are stored as either an MD5 hash or a bcrypt hash.

   • roles - the list of roles that the user is a member of. The default StackState roles are stackstate-admin,stackstate-platform-admin, stackstate-power-user and stackstate-guest, for details on how to create other roles, see RBAC roles.

2. Store the file authentication.yaml together with the file values.yaml from the StackState installation instructions.

3. Run a Helm upgrade to apply the changes:

    helm upgrade \
      --install \
      --namespace stackstate \
      --values values.yaml \
      --values authentication.yaml \
    stackstate \
    stackstate/stackstate

Note:

• An MD5 password hash can be generated using the md5sum or md5 command line applications on Linux and Mac.

• A bcrypt password hash can be generated using the following command line htpasswd -bnBC 10 "" <password> | tr -d ':\n' or using an online tool.

• The first run of the helm upgrade command will result in pods restarting, which may cause a short interruption of availability.

• Include authentication.yaml on every helm upgrade run.

• The authentication configuration is stored as a Kubernetes secret.

Linux

To configure file based authentication on Linux, StackState users need to be added to the application_stackstate.conf file. For example:

application:stackstate.conf

# Four users, `admin`, `platformadmin`, `power-user` and `guest`
# with the four default roles Administrator, Platform Administrator, Power user and Guest

authentication {
  authServer {
    authServerType = "stackstateAuthServer"

    stackstateAuthServer {
      # echo -n "password" | md5sum
      logins = [
        { username: "admin", password: "5f4dcc3b5aa765d61d8327deb882cf99", roles: ["stackstate-admin"] }
        { username: "platformadmin", password: "5f4dcc3b5aa765d61d8327deb882cf99", roles: ["stackstate-platform-admin"] }
        { username: "power-user", password: "5f4dcc3b5aa765d61d8327deb882cf99", roles: ["stackstate-power-user"] }
        { username: "guest", password: "5f4dcc3b5aa765d61d8327deb882cf99", roles: ["stackstate-guest"] }
      ]
    }
  }
}

Follow the steps below to configure users and apply changes:

1. In authentication.yaml - add users. The following configuration should be added for each user (see the example above):

   • username - the username used to log into StackState.

   • password - the password used to log into StackState. Passwords are stored as either an MD5 hash or a bcrypt hash.

   • roles - the list of roles that the user is a member of. The default StackState roles are stackstate-admin, stackstate-platform-admin, stackstate-power-user and stackstate-guest, for details on how to create other roles, see RBAC roles.

2. Restart StackState to apply the changes.

Note:

• An MD5 password hash can be generated using the md5sum or md5 command line applications on Linux and Mac.

• A bcrypt password hash can be generated using the following command line htpasswd -bnBC 10 "" <password> | tr -d ':\n' or using an online tool.
