FCP Setup

Table of Content

Prerequisites

Before you install the Computing Provider, you need to know there are some resources required:

  • Possess a public IP

  • Have a domain name (*.example.com)

  • Have an SSL certificate

  • Go version must 1.21+, you can refer here:

wget -c https://golang.org/dl/go1.21.7.linux-amd64.tar.gz -O - | sudo tar -xz -C /usr/local

echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.bashrc && source ~/.bashrc

Install the Kubernetes

The Kubernetes version should be v1.24.0+

Install Container Runtime Environment

If you plan to run a Kubernetes cluster, you need to install a container runtime into each node in the cluster so that Pods can run there, refer to here. And you just need to choose one option to install the Container Runtime Environment

Option 1: Install the Docker and cri-dockerd （Recommended）

To install the Docker Container Runtime and the cri-dockerd, follow the steps below:

  • Install the Docker:

    • Please refer to the official documentation from here.

  • Install cri-dockerd:

    • cri-dockerd is a CRI (Container Runtime Interface) implementation for Docker. You can install it refer to here.

Option 2: Install the Docker and theContainerd

  • Install the Docker:

    • Please refer to the official documentation from here.

  • To install Containerd on your system:

    • Containerd is an industry-standard container runtime that can be used as an alternative to Docker. To install containerd on your system, follow the instructions on getting started with containerd.

Optional-Setup a docker registry server

If you are using the docker and you have only one node, the step can be skipped.

If you have deployed a Kubernetes cluster with multiple nodes, it is recommended to set up a private Docker Registry to allow other nodes to quickly pull images within the intranet.

  • Create a directory /docker_repo on your docker server. It will be mounted on the registry container as persistent storage for our docker registry.

sudo mkdir /docker_repo
sudo chmod -R 777 /docker_repo

  • Launch the docker registry container:

sudo docker run --detach \
  --restart=always \
  --name registry \
  --volume /docker_repo:/docker_repo \
  --env REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY=/docker_repo \
  --publish 5000:5000 \
  registry:2
1

  • Add the registry server to the node

    • If you have installed the Docker and cri-dockerd(Option 1), you can update every node's configuration:

    sudo vi /etc/docker/daemon.json
    ## Add the following config
"insecure-registries": ["<Your_registry_server_IP>:5000"]

    Then restart the docker service

    sudo systemctl restart docker

    • If you have installed the containerd(Option 2), you can update every node's configuration:

[plugins."io.containerd.grpc.v1.cri".registry]
  [plugins."io.containerd.grpc.v1.cri".registry.mirrors]
    [plugins."io.containerd.grpc.v1.cri".registry.mirrors."<Your_registry_server_IP>:5000"]
      endpoint = ["http://<Your_registry_server_IP>:5000"]

[plugins."io.containerd.grpc.v1.cri".registry.configs]
  [plugins."io.containerd.grpc.v1.cri".registry.configs."<Your_registry_server_IP>:5000".tls]
      insecure_skip_verify = true

Then restart containerd service

sudo systemctl restart containerd

<Your_registry_server_IP>: the intranet IP address of your registry server.

Finally, you can check the installation by the command:

docker system info
2

Create a Kubernetes Cluster

To create a Kubernetes cluster, you can use a container management tool like kubeadm. The below steps can be followed:

Install the Network Plugin

Calico is an open-source networking and network security solution for containers, virtual machines, and native host-based workloads. Calico supports a broad range of platforms including Kubernetes, OpenShift, Mirantis Kubernetes Engine (MKE), OpenStack, and bare metal services.

To install Calico, you can follow the below steps, more information can be found here.

step 1: Install the Tigera Calico operator and custom resource definitions

kubectl create -f https://raw.githubusercontent.com/projectcalico/calico/v3.25.1/manifests/tigera-operator.yaml

step 2: Install Calico by creating the necessary custom resource

kubectl create -f https://raw.githubusercontent.com/projectcalico/calico/v3.25.1/manifests/custom-resources.yaml

step 3: Confirm that all of the pods are running with the following command

watch kubectl get pods -n calico-system

step 4: Remove the taints on the control plane so that you can schedule pods on it.

kubectl taint nodes --all node-role.kubernetes.io/control-plane-
kubectl taint nodes --all node-role.kubernetes.io/master-

If you have installed it correctly, you can see the result shown in the figure by the command kubectl get po -A

3

Note:

  • If you are a single-host Kubernetes cluster, remember to remove the taint mark, otherwise, the task can not be scheduled to it.

kubectl taint node ${nodeName}  node-role.kubernetes.io/control-plane:NoSchedule-

Install the NVIDIA Plugin

If your computing provider wants to provide a GPU resource, the NVIDIA Plugin should be installed, please follow the steps:

Recommend NVIDIA Linux drivers version should be 470.xx+

If you have installed it correctly, you can see the result shown in the figure by the command kubectl get po -n kube-system

4

Install the Ingress-nginx Controller

The ingress-nginx is an ingress controller for Kubernetes using NGINX as a reverse proxy and load balancer. You can run the following command to install it:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.7.1/deploy/static/provider/cloud/deploy.yaml

If you have installed it correctly, you can see the result shown in the figure by the command:

  • Run kubectl get po -n ingress-nginx

5

  • Run kubectl get svc -n ingress-nginx

6

Install and config the Nginx

  • Install Nginx service to the Server

sudo apt update
sudo apt install nginx

  • Add a configuration for your Domain name Assume your domain name is *.example.com

vi /etc/nginx/conf.d/example.conf
map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      close;
}

server {
        listen 80;
        listen [::]:80;
        server_name *.example.com;                                           # need to your domain
        return 301 https://$host$request_uri;
        #client_max_body_size 1G;
}
server {
        listen 443 ssl;
        listen [::]:443 ssl;
        ssl_certificate  /etc/letsencrypt/live/example.com/fullchain.pem;     # need to config SSL certificate
        ssl_certificate_key  /etc/letsencrypt/live/example.com/privkey.pem;   # need to config SSL certificate

        server_name *.example.com;                                            # need to config your domain
        location / {
          proxy_pass http://127.0.0.1:<port>;  	# Need to configure the Intranet port corresponding to ingress-nginx-controller service port 80 
          proxy_set_header Host $http_host;
          proxy_set_header Upgrade $http_upgrade;
          proxy_set_header Connection $connection_upgrade;
       }
}

  • Note:

    • server_name: a generic domain name

    • ssl_certificate and ssl_certificate_key: certificate for https.

    • proxy_pass: The port should be the Intranet port corresponding to ingress-nginx-controller service port 80

  • Reload the Nginx config

    sudo nginx -s reload

  • Map your "catch-all (wildcard) subdomain(*.example.com)" to a public IP address

Install the Hardware resource-exporter

The resource-exporter plugin is developed to collect the node resource constantly, computing provider will report the resource to the Lagrange Auction Engine to match the space requirement. To get the computing task, every node in the cluster must install the plugin. You just need to run the following command:

cat <<EOF | kubectl apply -f -
apiVersion: apps/v1
kind: DaemonSet
metadata:
  namespace: kube-system
  name: resource-exporter-ds
  labels:
    app: resource-exporter
spec:
  selector:
    matchLabels:
      app: resource-exporter
  template:
    metadata:
      labels:
       app: resource-exporter
    spec:
      containers:
      - name: resource-exporter
        image: filswan/resource-exporter:v11.2.8
        imagePullPolicy: IfNotPresent
        securityContext:
          privileged: true
EOF

If you have installed it correctly, you can see the result shown in the figure by the command: kubectl get po -n kube-system

Build and config the Computing Provider

  • Build the Computing Provider

    Firstly, clone the code to your local:

git clone https://github.com/swanchain/go-computing-provider.git
cd go-computing-provider
git checkout mainnet

Then build the Computing provider on the Swan Mainnet by following the below steps:

make clean && make mainnet
make install

If you want to test the CP in the testnet, please build a testnet version:

make clean && make testnet
make install

Initialize CP repo and Update Configuration

  1. Initialize repo

    computing-provider init --multi-address=/ip4/<YOUR_PUBLIC_IP>/tcp/<YOUR_PORT> --node-name=<YOUR_NODE_NAME>

    Note:

    • By default, the CP's repo is ~/.swan/computing, you can configure it by export CP_PATH="<YOUR_CP_PATH>"

    • The CP service port (8085 by default) must be mapped to the public IP address and port

  2. Update config.toml

    Edit the necessary configuration files according to your deployment requirements.

       [API]
   Port = 8085                                    # The port number that the web server listens on

Initialize a Wallet and Deposit SwanETH

  1. Generate a new wallet address or import the previous wallet:

    computing-provider wallet new

    Example output:

    0x7791f48931DB81668854921fA70bFf0eB85B8211

    or import your wallet:

    # Import wallet using the private key
computing-provider wallet import <YOUR_PRIVATE_KEY_FILE>

    Note: <YOUR_PRIVATE_KEY_FILE> is a file that contains the private key

  2. Deposit SwanETH to the wallet address:

    computing-provider wallet send --from <YOUR_WALLET_ADDRESS> 0x7791f48931DB81668854921fA70bFf0eB85B8211 0.01

    Note: If you don't have SwanETH and SWANC, please follow the guideline to bridge ETH to Swan Mainnet, and claim the SWANC as collaterals.

Initialization CP Account

Deploy a CP account contract:

computing-provider account create --ownerAddress <YOUR_OWNER_WALLET_ADDRESS> \
	--workerAddress <YOUR_WORKER_WALLET_ADDRESS> \
	--beneficiaryAddress <YOUR_BENEFICIARY_WALLET_ADDRESS>  \
	--task-types 3

Note: --task-types: Supports 4 task types (1: Fil-C2-512M, 2: Aleo, 3: AI, 4: Fil-C2-32G), separated by commas. For FCP, it needs to be set to 3.

Output:

Contract deployed! Address: 0x3091c9647Ea5248079273B52C3707c958a3f2658
Transaction hash: 0xb8fd9cc9bfac2b2890230b4f14999b9d449e050339b252273379ab11fac15926

Collateral SWANC for FCP

 computing-provider collateral add --fcp --from <YOUR_WALLET_ADDRESS>  <amount>

Note: Currently one AI task requires 5 SWANC. Please deposit enough collaterals for the tasks

Withdraw SWANC from FCP

 computing-provider collateral withdraw --fcp --owner <YOUR_WALLET_ADDRESS> --account <YOUR_CP_ACCOUNT> <amount>

Note: If you want to withdraw the funds from FCP, you can run the above command

Start the Computing Provider

You can run computing-provider using the following command

export CP_PATH=<YOUR_CP_PATH>
nohup computing-provider run >> cp.log 2>&1 &

[OPTIONAL] Install AI Inference Dependency

It is necessary for the Computing Provider to deploy the AI inference endpoint. But if you do not want to support the feature, you can skip it.

export CP_PATH=<YOUR_CP_PATH>
./install.sh

[OPTIONAL] Config and Receive ZK Tasks

This section mainly introduces how to enable the function of receiving ZK tasks on FCP, which is equivalent to running an ECP. This function is optional. Once enabled, FCP can earn double benefits simultaneously, but it will also consume certain resources.

Step 1: Prerequisites: Perform Filecoin Commit2 (fil-c2) ZK tasks.

  1. Download parameters (specify the path with PARENT_PATH variable):

    # At least 200G storage is needed
export PARENT_PATH="<V28_PARAMS_PATH>"

# 512MiB parameters
curl -fsSL https://raw.githubusercontent.com/swanchain/go-computing-provider/releases/ubi/fetch-param-512.sh | bash

# 32GiB parameters
curl -fsSL https://raw.githubusercontent.com/swanchain/go-computing-provider/releases/ubi/fetch-param-32.sh | bash

  2. Configure environment variables in fil-c2.env under CP repo ($CP_PATH):

    FIL_PROOFS_PARAMETER_CACHE=$PARENT_PATH
RUST_GPU_TOOLS_CUSTOM_GPU="GeForce RTX 3080:8704"

Step 2: Collateral SWANC for ZK tasks

computing-provider collateral add --ecp --from <YOUR_WALLET_ADDRESS>  <amount>

If you want to withdraw the collateral SWANC:

computing-provider collateral withdraw --ecp --owner <YOUR_WALLET_ADDRESS> --account <YOUR_CP_ACCOUNT> <amount>

Note: A minimum of 100 SWANC collateral is required to receive a ZK task.

Step 3: Change the tasktypes

computing-provider account changeTaskTypes --ownerAddress <YOUR_OWNER_WALLET_ADDRESS> 1,2,3,4

Note: --task-types Supports 4 task types:

  • 1: FIL-C2-512M

  • 2: Aleo

  • 3: AI

  • 4: FIL-C2-32G

If you need to run FCP and ECP at the same time, you need to set it to 1,2,3,4

Step 4: Deposit SwanETH for Sequencer Account

computing-provider sequencer add --from <YOUR_WALLET_ADDRESS>  <amount>

If you want to Withdraw SwanETH from Sequencer Account

computing-provider sequencer withdraw --owner <YOUR_OWNER_WALLET_ADDRESS>  <amount>

Step 5: Account Management

Use computing-provider account subcommands to update CP details:

computing-provider account -h
NAME:
   computing-provider account - Manage account info of CP

USAGE:
   computing-provider account command [command options] [arguments...]

COMMANDS:
   create                    Create a cp account to chain
   changeMultiAddress        Update MultiAddress of CP (/ip4/<public_ip>/tcp/<port>)
   changeOwnerAddress        Update OwnerAddress of CP
   changeWorkerAddress       Update workerAddress of CP
   changeBeneficiaryAddress  Update beneficiaryAddress of CP
   changeTaskTypes           Update taskTypes of CP (1:Fil-C2-512M, 2:Aleo, 3: AI, 4:Fil-C2-32G), separated by commas
   help, h                   Show a list of commands or help for one command

OPTIONS:
   --help, -h  show help

Step 6: Check the Status of ZK task;

To check the ZK task list, use the following command:

computing-provider ubi list --show-failed

Example output:
