How to Connect to Local Postgres 14.7 in Docker Using Generic JDBC Snap on Port 5432?
i have a local postgres:14.7 server running through docker. I want to make a jdbc connection through the generic jdbc snap, how should i do it? (assume port 5432)

Here's a step-by-step guide on how to configure a Generic JDBC Account in SnapLogic to connect to your local PostgreSQL 14.7 Docker instance: --- 🐘 Connecting to Local PostgreSQL via Generic JDBC in SnapLogic ⚠️ Important Pre-requisite: Groundplex Required Since your PostgreSQL is running locally via Docker, you must use a Groundplex (a locally-installed Snaplex node). A Cloudplex cannot reach your local machine's network. Make sure your Groundplex is running and can reach the Docker container. --- Step 1: Download the PostgreSQL JDBC Driver JAR Download the PostgreSQL JDBC driver from the official site: 👉 [https://jdbc.postgresql.org/download/](https://jdbc.postgresql.org/download/) - Recommended: postgresql-42.7.2.jar (Java 8 compatible) - Upload this JAR to your SnapLogic Shared folder via the Manager. --- Step 2: Create a Generic JDBC Account 1. In the Designer, drag any Generic JDBC Snap onto the canvas and open it. 2. Go to the Account tab → click Add Account. 3. Select Generic JDBC Account as the account type. --- Step 3: Configure the Account Settings Fill in the following fields: | Field | Value | |---|---| | JDBC Driver JAR | Select the uploaded postgresql-42.7.2.jar | | JDBC Driver Class | org.postgresql.Driver | | JDBC URL | jdbc:postgresql://<your-host>:5432/<your-database> | | Username | Your PostgreSQL username (e.g., postgres) | | Password | Your PostgreSQL password | 🔧 For the JDBC URL — Docker Considerations: Depending on how your Docker container is set up, use the appropriate host: | Scenario | Host to use | |---|---| | Groundplex running on the same machine as Docker | localhost or 127.0.0.1 | | Groundplex running inside Docker on the same network | Use the container name or Docker bridge IP (e.g., 172.17.0.x) | | Groundplex on a different machine | Use the host machine's IP address | Example URL:
jdbc:postgresql://localhost:5432/mydb
--- Step 4: (Optional) Add URL Properties If you encounter connection timeout issues, add these under URL Properties: | URL Property Name | URL Property Value | |---|---| | socketTimeout | 10 | --- Step 5: Validate the Account Click Validate to test the connection. If successful, click Apply. --- 🛠️ Common Troubleshooting Tips - Driver not found: Make sure the JAR is uploaded to SnapLogic's file system and correctly referenced in the account. - Connection refused: Ensure your Docker container exposes port 5432 (e.g., -p 5432:5432 in your docker run command) and that no firewall is blocking it. - Multiple JDBC accounts: If you have other JDBC accounts with broken drivers, they can cause all JDBC connections to fail. Fix or remove broken drivers and restart the JCC node. --- Let me know if you need help with any specific step or run into an error! 🚀
