### docker-compose ### docker-compose
The recommended way to run a scribe hub is with docker. The recommended way to run a scribe hub is with docker. See [this guide](https://github.com/lbryio/scribe/blob/master/cluster_guide.md) for instructions on how to run the services on a cluster.
If you have the resources to run all of the services on one machine (at least 300gb of fast storage, preferably nvme, 64gb of RAM, 12 fast cores), see [this](https://github.com/lbryio/scribe/blob/master/docker/docker-compose.yml) docker-compose example. If you have the resources to run all of the services on one machine (at least 300gb of fast storage, preferably nvme, 64gb of RAM, 12 fast cores), see [this](https://github.com/lbryio/scribe/blob/master/docker/docker-compose.yml) docker-compose example.
#### Cluster environment
For best performance the recommended setup uses three server instances, these can be rented VPSs, self hosted VMs (ideally not on one physical host unless the host is sufficiently powerful), or physical computers. One is a dedicated lbcd node, one an elasticsearch server, and the third runs the scribe services. With this configuration the lbcd and elasticsearch servers can be shared between multiple scribe hub servers - more on that later.
Server Requirements (space requirements are at least double what's needed so it's possible to copy snapshots into place or make snapshots):
- lbcd: 2 cores, 8gb ram (slightly more may be required syncing from scratch, from a snapshot 8 is plenty), 150gb of NVMe storage
- elasticsearch: 8 cores, 9gb of ram (8gb minimum given to ES), 150gb of SSD speed storage
- scribe: 8 cores, 32gb of ram, 200gb of NVMe storage
All servers are assumed to be running ubuntu 20.04 with user named `lbry` with passwordless sudo and docker group permissions, ssh configured, ulimits set high, and docker + docker-compose installed. The server running elasticsearch should have swap disabled. The three servers need to be able to communicate with each other, they can be on a local network together or communicate over the internet. This guide will assume the three servers are on the internet.
##### Setting up the lbcd instance
Log in to the lbcd instance and perform the following steps:
- Build the lbcd docker image by running
```
git clone https://github.com/lbryio/lbcd.git
cd lbcd
docker build . -t lbry/lbcd:latest
```
- Copy the following to `~/docker-compose.yml`
```
version: "3"
volumes:
lbcd:
services:
lbcd:
image: lbry/lbcd:latest
restart: always
network_mode: host
command:
- "--rpcuser=lbry"
- "--rpcpass=lbry"
- "--rpclisten=127.0.0.1"
volumes:
- "lbcd:/root/.lbcd"
ports:
- "127.0.0.1:9245:9245"
- "9246:9246" # p2p port
```
- Start lbcd by running `docker-compose up -d`
- Check the progress with `docker-compose logs -f --tail 100`
##### Setting up the elasticsearch instance
Log in to the elasticsearch instance and perform the following steps:
- Copy the following to `~/docker-compose.yml`
```
version: "3"
volumes:
es01:
services:
es01:
image: docker.elastic.co/elasticsearch/elasticsearch:7.16.0

volumes:

- "127.0.0.1:9200:9200"
```
- Start elasticsearch by running `docker-compose up -d`
- Check the status with `docker-compose logs -f --tail 100`
##### Setting up the scribe hub instance
- Log in (ssh) to the scribe instance and generate and print out a ssh key, this is needed to set up port forwards to the other two instances. Copy the output of the following:
```
ssh-keygen -q -t ed25519 -N '' -f ~/.ssh/id_ed25519 <<<y >/dev/null 2>&1
```
- After copying the above key, log out of the scribe hub instance.
- Log in to the elasticsearch instance add the copied key to `~/.ssh/authorized_keys` (see [this](https://stackoverflow.com/questions/6377009/adding-a-public-key-to-ssh-authorized-keys-does-not-log-me-in-automatically) if confused). Log out of the elasticsearch instance once done.
- Log in to the lbcd instance and add the copied key to `~/.ssh/authorized_keys`, log out when done.
- Log in to the scribe instance and copy the following to `/etc/systemd/system/es-tunnel.service`, replacing `lbry` with your user and `your-elastic-ip` with your elasticsearch instance ip.
