Agenta Local Setup

[Arshil-Akkala]

Hi, I am facing issue while setting up Agenta locally, via docker images.
I used this cmd docker compose -f docker-compose.gh.yml up -d --pull always, but I am getting DB issues.
I even connected to postgres DB with mentioned details in the docker compose file.

To troubleshoot the database issues you're encountering with the Agenta local setup, here are a few steps you can follow:

1. Verify Database Credentials: Ensure that the PostgreSQL credentials in your docker-compose.gh.yml file match the ones you're using to connect. The default credentials are:

   • User: username
   • Password: password
   • Database: agenta_oss
   • Host: postgres
   • Port: 5432 ^[1].

2. Check Service Health: Make sure the postgres service is healthy. You can check the logs using:

   docker compose logs postgres

   Look for any errors or warnings that might indicate why the service isn't starting properly.

3. Apply Migrations: Ensure that the apply_alembic_migration service has completed successfully. This service is responsible for applying database migrations. Check its logs for any issues:

   docker compose logs apply_alembic_migration

4. Network Configuration: Confirm that all services are connected to the agenta-network. This ensures that they can communicate with each other.

5. Restart Services: Sometimes, simply restarting the services can resolve transient issues:

   docker compose down
   docker compose up -d

6. Inspect Docker Volumes: Ensure that the Docker volumes for PostgreSQL are correctly set up and accessible. You can inspect them using:

   docker volume ls

If these steps don't resolve the issue, please provide any specific error messages from the logs for further assistance.

Upon this, I was following
https://docs.agenta.ai/self-host/migration/applying-schema-migration
For this, I am getting not found

[Arshil-Akkala]

These are the logs for migration container.

These are my postgres logs.

Upon running this
docker exec -w /app/agenta_backend/migrations/postgres agenta-backend-1 alembic -c alembic.oss.ini upgrade head

got this

Is there a way through which I can run this as a fresh user using postgres, instead of migrating from mongodb to postgres?

[dosubot[bot]]

To set up a fresh PostgreSQL database for Agenta without migrating from MongoDB, you can initialize the database using the following SQL script:

DO $$ 
BEGIN
   IF NOT EXISTS (
      SELECT 
      FROM   pg_catalog.pg_database 
      WHERE  datname = 'agenta_oss') THEN
      CREATE DATABASE agenta_oss;
   END IF;
END
$$;

-- Create the username role with a password
DO $$
BEGIN
   IF NOT EXISTS (
      SELECT 
      FROM   pg_catalog.pg_roles 
      WHERE  rolname = 'username') THEN
      CREATE ROLE username WITH LOGIN PASSWORD 'password';
   END IF;
END
$$;

-- Grant necessary permissions to username
GRANT ALL PRIVILEGES ON DATABASE agenta_oss TO username;

-- Connect to the agenta_oss database
\c agenta_oss

-- Grant schema permissions to username
GRANT ALL ON SCHEMA public TO username;

Make sure to replace 'username' and 'password' with your desired username and password. This script will create a new PostgreSQL database named agenta_oss, set up a user role, and grant the necessary permissions ^[1].

Additionally, ensure that your docker-compose.yml file is configured correctly with the appropriate environment variables for PostgreSQL:

• POSTGRES_URI: Set to postgresql+asyncpg://username:password@postgres:5432/agenta_oss.
• POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_DB: Set these in the postgres service to match your credentials and database name ^[2][3][4].

After setting up the database and configuring the environment variables, you can proceed with running the necessary migrations to set up the database schema.

If you're looking to start fresh with PostgreSQL for Agenta, you can follow these steps:

1. Remove Existing Containers and Volumes: First, ensure that any existing Docker containers and volumes related to Agenta are removed to avoid conflicts.

   docker compose down -v

2. Initialize a Fresh Database: Use the SQL script provided earlier to create a new database and user. You can execute this script by connecting to the PostgreSQL container:

   docker exec -it <postgres-container-name> psql -U postgres

   Then, run the SQL commands to set up the database and user.

3. Update Docker Compose Configuration: Ensure your docker-compose.yml file is set up with the correct environment variables for a fresh start:

   • POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_DB should match the credentials and database name you set up.

4. Run Migrations: After setting up the database, run the migrations to create the necessary tables and schema:

   docker compose up apply_alembic_migration

5. Start the Services: Once the migrations are complete, start the services:

   docker compose up -d

This process will set up a fresh PostgreSQL database for Agenta without any previous data or migrations from MongoDB. If you encounter any issues, check the logs for specific error messages and ensure all configurations are correct.
