Maintenance mode¶
Table of contents
Introduction¶
When updates are being rolled out to your Hasura Cloud project which demand no interruptions to your instance’s configuration, maintenance mode is activated for your project.
Note
Currently, cloud maintenance mode will only be activated for your project while you
are updating it to Hasura GraphQL Engine v2.0.
Note
This is not to be confused with environment variable HASURA_GRAPHQL_ENABLE_MAINTENANCE_MODE.
The two are different as the env var enables the server maintenance mode which disables metadata APIs
(writes) on the project while the cloud maintenance mode does not. See below for actions disabled
by the cloud maintenance mode.
Check if maintenance mode is activated¶
Navigate to your project’s settings page, you should see a top banner mentioning if your project is under maintenance.
If you don’t see such a banner, your project is not under maintenance mode.
Disabled actions when maintenance mode is activated¶
All actions that update your project’s configurations are not allowed when maintenance mode is activated. The following actions are disallowed:
- Switching pricing plans
- Adding, updating and deleting an environment variable
- Changing project region
- Enabling and disabling Heroku database URL sync
- Deleting project
If you are trying to apply these changes when maintenance mode is activated, you will encounter an error.
