# Running in Docker

## 1) Get RAI

Buy RAI from Uniswap v2 or [open a SAFE](https://app.gitbook.com/@reflexer-labs/s/geb/pyflex/safe-management/opening-a-safe) and generate it.

## 2) Create the keeper run file

Create a file called `run_auction_keeper.sh` and paste the following code in it:

```
#!/bin/bash

docker run -it \
    -v <KEYSTORE DIR>:/keystore \
    reflexer/auction-keeper:latest \
        --rpc-uri <ETH_RPC_URL> \
        --eth-from <KEEPER ADDRESS> \
        --eth-key key_file=/keystore/<KEYSTORE FILE>
```

### Then, substitute the following variables:

`KEYSTORE_DIR` - the local directory where your keystore file is

`KEYSTORE_FILE` - your Ethereum UTC JSON keystore filename

For more information about this keystore format and how to generate them:

* [Ethereum UTC / JSON Wallet Encryption](https://wizardforcel.gitbooks.io/practical-cryptography-for-developers-book/content/symmetric-key-ciphers/ethereum-wallet-encryption.html)
* [keythereum](https://github.com/ethereumjs/keythereum)

`ETH_RPC_URL` - the URL of the ethereum RPC connection

`KEEPER_ADDRESS` - the keeper's address. It must be in a checksummed format

### Finally:

`chmod +x run_auction_keeper.sh`

## 3) Start the keeper and enter your keystore file password

`./run_auction_keeper.sh`

```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.reflexer.finance/keepers/collateral-auction-keeper/running-in-docker.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
