MongoDB Deployment Example

This guide demonstrates how to deploy a MongoDB instance using Instantly.run.

Deployment Command

docker run --context=instantly --name mongo-db --domainname db.example.com \
-e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=strongpassword \
-p 27017:27017 -v ssd:/data/db

Command Breakdown

  • --context=instantly: Ensures the container is managed under the Instantly.run context.
  • --name mongo-db: Assigns the container a unique name for reference.
  • --domainname db.example.com: Assigns the container a public domain (used for internal access).
  • Environment Variables:
    • MONGO_INITDB_ROOT_USERNAME: The root username for MongoDB.
    • MONGO_INITDB_ROOT_PASSWORD: The root password for MongoDB.
  • -p 27017:27017: Maps the MongoDB service port to the host.
  • -v ssd:/data/db: Mounts a volume to persist MongoDB data.

Accessing the Deployment

  • Internal Hostname: The MongoDB instance will be accessible internally at db-example-com:27017.
  • Public Access: MongoDB is not exposed publicly due to Instantly.run's HTTP/HTTPS limitation for public domains.

Modifying the Deployment

To make updates (e.g., change the credentials or volumes), re-run the command with updated parameters. For example, to change the volume mapping:

docker run --context=instantly --name mongo-db --domainname db.example.com \
-e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=newpassword \
-p 27017:27017 -v hdd:/data/db

Additional Configuration

For more configuration options, refer to the MongoDB Docker Documentation.
