# Using Docker

{% hint style="info" %}
Note that the configuration may change while testing. Please check this page consistently for operation info.
{% endhint %}

One of the quickest ways to run verifier is by using Docker:

## Use Private Key (mode = 0)

**Update config\_docker.yaml**

Update your private\_key and run :

```
wallet:
  # wallet mode, by which way to pass the private key
  # 0: through startup parameters
  # 1: through plain text private key in config file
  # 2: through path and password of the keystore in config file
  mode: 0
  # plain text private key, needed when mode is 1
  private_key: "99a038e9d345d0b12130b3b1fb003bf8f2d3a5c27ce2a800bbb1608efff6c591"
  # path of the keystore, needed when mode is 2
  keystore_path: ""
  # password of the keystore, needed when mode is 2
  keystore_password: ""
```

```
docker run -d --name verifier -v /<Path To This Repository>/verifier/configs:/data/conf -v /<Path To Keystore direction>:/data/keystore carvprotocol/verifier:mainnet
```

## **Use Keystore (mode = 2)**

> If you want to use keystore, you need to generate a keystore file first. You can use the following command to generate a keystore file.

```
./verifier -generate-keystore -keystore-path <path to generate your keystore file>
```

After running the command, you can run verifier by following the steps below.

**update config\_docker.yaml**

Update your keystore\_path and keystore\_password and run :

```
wallet:
  # wallet mode, by which way to pass the private key
  # 0: through startup parameters
  # 1: through plain text private key in config file
  # 2: through path and password of the keystore in config file
  mode: 2
  # plain text private key, needed when mode is 1
  private_key: ""
  # path of the keystore, needed when mode is 2
  keystore_path: "/data/conf/xxxx/UTC--2021-09-29T07-00-00.000000000Z--xxxx"
  # password of the keystore, needed when mode is 2
  keystore_password: "123456"
```

```
docker run -d --name verifier -v /<Path To This Repository>/verifier/configs:/data/conf -v /<Path To Keystore direction>:/data/keystore carvprotocol/verifier:mainnet
```
