If there are self signed HTTPS endpoints that Tooljet needs to connect to, please make sure that `NODE_EXTRA_CA_CERTS` environment variable is set to the absolute path containing the certificates. You can make use of kubernetes secrets to mount the certificate file onto the containers.
It might take a few minutes to provision the managed certificates. [Managed certificates documentation](https://cloud.google.com/kubernetes-engine/docs/how-to/managed-certs).
:::
You will be able to access your ToolJet installation once the pods, service and the ingress is running.
## ToolJet Database
To use the ToolJet Database, you need to set up and deploy a PostgREST server, which facilitates querying the database. Detailed setup instructions are available [here](/docs/tooljet-db/tooljet-database).
Starting with ToolJet 3.0, deploying the ToolJet Database is mandatory to avoid migration issues. Refer to the documentation below for details on the new major version, including breaking changes and required adjustments for your applications.
- [ToolJet 3.0 Migration Guide for Self-Hosted Versions](./upgrade-to-v3.md)
2. Update ToolJet deployment with the appropriate env variables [here](https://tooljet-deployments.s3.us-west-1.amazonaws.com/kubernetes/GKE/deployment.yaml) and apply the changes.
## Upgrading to the Latest LTS Version
New LTS versions are released every 3-5 months with an end-of-life of atleast 18 months. To check the latest LTS version, visit the [ToolJet Docker Hub](https://hub.docker.com/r/tooljet/tooljet/tags) page. The LTS tags follow a naming convention with the prefix `LTS-` followed by the version number, for example `tooljet/tooljet:ee-lts-latest`.
If this is a new installation of the application, you may start directly with the latest version. This guide is not required for new installations.
#### Prerequisites for Upgrading to the Latest LTS Version:
- It is crucial to perform a **comprehensive backup of your database** before starting the upgrade process to prevent data loss.
- Users on versions earlier than **v2.23.0-ee2.10.2** must first upgrade to this version before proceeding to the LTS version.
