# Docker Install

# Install & Configure Docker

## Key folder structure

Livepeer will require files to be placed on the host and within the docker
container. Here is a list of the key folders used by the docker install.

### Host Folders

By default, docker will store all volumes in the `/var/lib/docker/volumes`
directory

This installation will create a volume called: `gateway-lpData` and it will be
located at `/var/lib/docker/volumes/gateway-lpData/_data`

### Container Folders

Within the docker container, the volume `gateway-lpData` will be mounted at
`/root/.lpData`

## Install Prerequisites

If docker is already installed, you can skip this step. The installation assumes
you are running Docker 20.10.x. If an older version of docker is installed
remove it with the following command:

As the root user (or sudo), run the following:

```
apt remove docker*
```

Install Docker

```
curl https://releases.rancher.com/install-docker/20.10.sh | sh
```

Create a Docker volume

```
docker volume create gateway-lpData
```

Create Docker Compose file from the root user's home directory */root/*

```
nano docker-compose.yml
```

Copy and paste the following and save the following

```
version: '3.9'

services:
   gateway:
    image: livepeer/go-livepeer:<RELEASE_VERSION>
    container_name: "gateway"
    hostname: "gateway"
    ports:
      - 1935:1935
      - 8935:8935
    volumes:
      - gateway-lpData:/root/.lpData
    command: '-ethUrl=https://arb1.arbitrum.io/rpc/
              -ethKeystorePath=/root/.lpData
              -network=arbitrum-one-mainnet
              -cliAddr=gateway:5935
              -broadcaster=true
              -monitor=true
              -v=99
              -blockPollingInterval=20
              -maxPricePerUnit=300
              -pixelsPerUnit=1
              -rtmpAddr=0.0.0.0:1935
              -httpAddr=0.0.0.0:8935
              '
volumes:
  gateway-lpData:
    external: true
```

# Create Livepeer Gateway ETH account

In this step we need to start the Gateway in order to create an Ethereum
account.

```
docker compose run -it gateway
```

When prompted for the ETH password, enter a strong password to secure your
Ethereum account. This password is used to decrypt and access the ETH private
key. <Warning>Make sure to never share or lose access to either the password or
the keystore file.</Warning>

<Tip>Keep this password handy, we will use it in the following steps.</Tip>

After you see the message that the Ethereum account has been unlocked, CTRL+C to
exit the Livepeer docker instance.

Using the previously created ETH password, create the eth-secret file

```
nano -p /var/lib/docker/volumes/gateway-lpData/_data/eth-secret.txt
```

# Modify Docker compose file to include eth-secret.txt

```
nano docker-compose.yml
```

Add the following line below the `-ethKeystorePath` and save

```
-ethPassword=/root/.lpData/eth-secret.txt
```

Here is the full modified version of the docker-compose.yml file

```
version: '3.9'

services:
  gateway:
    image: livepeer/go-livepeer:<RELEASE_VERSION>
    container_name: "gateway"
    hostname: "gateway"
    ports:
      - 1935:1935
      - 8935:8935
    volumes:
      - gateway-lpData:/root/.lpData
    command: '-ethUrl=<YOUR ARB APC>
              -ethKeystorePath=/root/.lpData
              -ethPassword=/root/.lpData/eth-secret.txt
              -network=arbitrum-one-mainnet
              -cliAddr=gateway:5935
              -broadcaster=true
              -monitor=true
              -v=99
              -blockPollingInterval=20
              -maxPricePerUnit=300
              -pixelsPerUnit=1
              -rtmpAddr=0.0.0.0:1935
              -httpAddr=0.0.0.0:8935
              '
volumes:
  gateway-lpData:
    external: true
```

Start Livepeer in the background

```
docker compose up -d
```

Launch the livepeer\_cli

```
docker exec -it gateway /bin/bash
livepeer_cli -host gateway -http 5935
```
