# Deploying **trains-server** on AWS

To easily deploy **trains-server** on AWS, use one of our pre-built Amazon Machine Images (AMIs).  
We provide AMIs per region for each released version of **trains-server**, see [Released versions](#released-versions) below. 

Once the AMI is up and running, [configure the Trains client](https://github.com/allegroai/trains/blob/master/README.md#configuration) to use your **trains-server**.  
The service port numbers on our **trains-server** AMIs:

- Web application: `8080`
- API Server: `8008`
- File Server: `8081`

The persistent storage configuration:

- MongoDB: `/opt/trains/data/mongo/`
- ElasticSearch: `/opt/trains/data/elastic/`
- File Server: `/mnt/fileserver/`

For examples and use cases, check the [Trains usage examples](https://github.com/allegroai/trains/blob/master/docs/trains_examples.md).

For instructions on launching a custom AMI from the EC2 console, see the [AWS Knowledge Center](https://aws.amazon.com/premiumsupport/knowledge-center/launch-instance-custom-ami/) or detailed instructions in the [AWS Documentation](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/launching-instance.html).

The minimum recommended amount of RAM is 8GB. For example, **t3.large** or **t3a.large** would have the minimum recommended amount of resources.

## Upgrading

To upgrade **trains-server** on an existing EC2 instance based on one of these AMIs, SSH into the instance and follow the [upgrade instructions](../README.md#upgrade) for **trains-server**.

### Upgrading AMIs to v0.12 

This upgrade includes the automatically updated AMI in Version 0.12. It also includes an additional REDIS docker to the **trains-server** setup.

To upgrade the AMI:

1. SSH to the EC2 machine running one of the `Latest Version AMI's`
2. Execute the following bash commands
    ```bash
    sudo bash
    echo "" >>  /usr/bin/start_or_update_server.sh
    echo "sudo mkdir -p \${datadir}/redis" >>  /usr/bin/start_or_update_server.sh
    echo "sudo docker stop trains-redis || true && sudo docker rm -v trains-redis || true" >>  /usr/bin/start_or_update_server.sh
    echo "echo never | sudo tee -a  /sys/kernel/mm/transparent_hugepage/enabled" >>  /usr/bin/start_or_update_server.sh
    echo "sudo sysctl vm.overcommit_memory=1" >>  /usr/bin/start_or_update_server.sh
    echo "sudo docker run -d --restart=always --name=trains-redis -v \${datadir}/redis:/data --network=host redis:5 redis-server" >>  /usr/bin/start_or_update_server.sh
    ``` 
3. Reboot the EC2 machine
