--- id: openshift title: Openshift --- # Deploying ToolJet on Openshift :::warning To use ToolJet AI features in your deployment, make sure to whitelist `https://api-gateway.tooljet.com` and `https://python-server.tooljet.com` in your network settings. ::: :::info You should setup a **PostgreSQL database** manually to be used by ToolJet. You can find the system requirements [here](/docs/3.5.0-LTS/setup/system-requirements#postgresql). ToolJet runs with **built-in Redis** for multiplayer editing and background jobs. When running **separate worker containers** or **multi-pod setup**, an **external Redis instance** is **required** for job queue coordination. ::: Follow the steps below to deploy ToolJet on Openshift. 1. Setup a PostgreSQL database ToolJet uses a postgres database as the persistent storage for storing data related to users and apps. ``` TOOLJET_HOST= LOCKBOX_MASTER_KEY= SECRET_KEY_BASE= PG_USER= PG_HOST= PG_PASS= PG_DB=tooljet_production # Must be a unique database name (do not reuse across deployments) ``` Also, for setting up additional environment variables in the .env file, please check our documentation on environment variables [here](/docs/setup/env-vars). 2. Once you have logged into the Openshift developer dashboard click on `+Add` tab. Select import YAML from the local machine. :::note When entering one or more files and use --- to separate each definition ::: Copy paste deployment.yaml to the online editor ``` curl -LO https://tooljet-deployments.s3.us-west-1.amazonaws.com/openshift/deployment.yaml ``` Copy paste the service.yaml to the online editor ``` curl -LO https://tooljet-deployments.s3.us-west-1.amazonaws.com/openshift/service.yaml ``` online yaml editor Once you have added the files click on create. :::info 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. ::: 3. Navigate to topology tab and use the visual connector to establish the connect between tooljet-deployment and postgresql as shown in the screenshot below. topology ## ToolJet Database Use the ToolJet-hosted database to build apps faster, and manage your data with ease. You can learn more about this feature [here](/docs/tooljet-db/tooljet-database). Deploying ToolJet Database is mandatory from ToolJet 3.0 or else the migration might break. Checkout the following docs to know more about new major version, including breaking changes that require you to adjust your applications accordingly: - [ToolJet 3.0 Migration Guide for Self-Hosted Versions](./upgrade-to-v3.md) #### Setting Up ToolJet Database To set up ToolJet Database, the following **environment variables are mandatory** and must be configured: ```env TOOLJET_DB=tooljet_db # Must be a unique database name (separate from PG_DB and not shared) TOOLJET_DB_HOST= TOOLJET_DB_USER= TOOLJET_DB_PASS= ``` :::note Ensure that `TOOLJET_DB` is not the same as `PG_DB`. Both databases must be uniquely named and not shared. ::: Additionally, for **PostgREST**, the following **mandatory** environment variables must be set: :::tip If you have openssl installed, you can run the command `openssl rand -hex 32` to generate the value for `PGRST_JWT_SECRET`. If this parameter is not specified, PostgREST will refuse authentication requests. ::: ```env PGRST_HOST=localhost:3001 PGRST_LOG_LEVEL=info PGRST_DB_PRE_CONFIG=postgrest.pre_config PGRST_SERVER_PORT=3001 PGRST_DB_URI= PGRST_JWT_SECRET= ``` The **`PGRST_DB_URI`** variable is **required** for PostgREST, which exposes the database as a REST API. This must be explicitly set for proper functionality. #### Format: ```env PGRST_DB_URI=postgres://TOOLJET_DB_USER:TOOLJET_DB_PASS@TOOLJET_DB_HOST:5432/TOOLJET_DB ``` **Ensure these configurations are correctly set up before proceeding with the ToolJet deployment. Make sure these environment variables are set in the same environment as the ToolJet deployment.** ## Workflows ToolJet Workflows allows users to design and execute complex, data-centric automations using a visual, node-based interface. This feature enhances ToolJet's functionality beyond building secure internal tools, enabling developers to automate complex business processes. :::info For users migrating from Temporal-based workflows, please refer to the [Workflow Migration Guide](./workflow-temporal-to-bullmq-migration). ::: ### Enabling Workflow Scheduling To activate workflow scheduling, set the following environment variables in your ToolJet deployment: ```bash # Worker Mode (required) # Set to 'true' to enable job processing # Set to 'false' or unset for HTTP-only mode (scaled deployments) WORKER=true # Workflow Processor Concurrency (optional) # Number of workflow jobs processed concurrently per worker # Default: 5 TOOLJET_WORKFLOW_CONCURRENCY=5 ``` **Environment Variable Details:** - **WORKER** (required): Enables job processing. Set to `true` to activate workflow scheduling - **TOOLJET_WORKFLOW_CONCURRENCY** (optional): Controls the number of workflow jobs processed concurrently per worker instance. Default is 5 if not specified :::warning **External Redis Requirement**: When running separate worker containers or multiple instances, an external stateful Redis instance is **required** for job queue coordination. The built-in Redis only works when the server and worker are in the same container instance (single instance deployment). ::: #### Deploying Redis for Workflows Deploy a stateful Redis instance using the following example configuration: ```bash kubectl apply -f https://tooljet-deployments.s3.us-west-1.amazonaws.com/kubernetes/redis-stateful.yaml ```
Built-in Redis vs External Redis ToolJet images include a built-in Redis instance for development. When deploying workflows in production, you must update your deployment configuration to use the external stateful Redis: Change **REDIS_HOST** from **localhost** to **redis-service** in your deployment YAML: ```yaml - name: REDIS_HOST value: redis-service # Changed from localhost - name: REDIS_PORT value: "6379" ```
This example deployment creates: - A StatefulSet with persistent storage for Redis - A headless Service for stable network identity - ConfigMap with production-ready Redis configuration - A Secret for optional password authentication :::info This is an example configuration that you can customize to your needs. However, **AOF (Append Only File) persistence** and **`maxmemory-policy noeviction`** are critical settings that must be maintained for BullMQ job queue reliability. ::: After deploying Redis, configure ToolJet to connect to it using these environment variables in your deployment: ```bash REDIS_HOST=redis-service.default.svc.cluster.local REDIS_PORT=6379 REDIS_PASSWORD=your-secure-redis-password-here # Match the password in redis-secret ``` **Optional Redis Configuration:** - `REDIS_USERNAME=` - Redis username (ACL) - `REDIS_DB=0` - Redis database number (default: 0) - `REDIS_TLS=false` - Enable TLS/SSL (set to 'true') **Note:** Update the `redis-secret` in the Redis deployment YAML with a secure password before deploying to production. **Note:** Ensure that these environment variables are added to your OpenShift deployment configuration (e.g., in your deployment.yaml file). ## 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. _If you have any questions feel free to join our [Slack Community](https://join.slack.com/t/tooljet/shared_invite/zt-2rk4w42t0-ZV_KJcWU9VL1BBEjnSHLCA) or send us an email at support@tooljet.com._
