When configured like this, the *Homeserver URL* field in synapse-admin's web UI changes from a text field to a dropdown having a single value (the URL of your homeserver). This makes usage simpler for most people, as they won't need to manually enter a *Homeserver URL* anymore. + +If you'd like **to go back to the old unrestricted behavior**, use the following configuration: + +```yml +# Use this configuration to allow synapse-admin to manage any homeserver instance. +matrix_synapse_admin_config_restrictBaseUrl: [] +``` + + # 2024-06-25 ## The URL-prefix for Hookshot generic webhooks has changed diff --git a/docs/configuring-playbook-synapse-admin.md b/docs/configuring-playbook-synapse-admin.md index 1e3e8980e..0b80f27ba 100644 --- a/docs/configuring-playbook-synapse-admin.md +++ b/docs/configuring-playbook-synapse-admin.md @@ -20,14 +20,12 @@ matrix_synapse_admin_enabled: true - for [Synapse](./configuring-playbook-synapse.md) (our default homeserver implementation): `matrix_synapse_container_labels_public_client_synapse_admin_api_enabled: true` - for [Dendrite](./configuring-playbook-dendrite.md): `matrix_dendrite_container_labels_public_client_synapse_admin_api_enabled: true` +By default, synapse-admin installation will be [restricted to only work with one homeserver](https://github.com/Awesome-Technologies/synapse-admin/blob/e21e44362c879ac41f47c580b04210842b6ff3d7/README.md#restricting-available-homeserver) - the one managed by the playbook.
