Installing exchanger-api / DONE

Rest-API installation on your own servers is available only if you purchase a full BoxExchanger software licence

Prepare dependencies

apt update
apt upgrade -y
apt install -y nano sudo curl wget

1. Install Docker and Docker Compose

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

2. Create runner user and add it to sudoers

sudo adduser --disabled-password --gecos "" runner
sudo usermod -aG sudo runner

3. Create docker group and add user to it

sudo usermod -aG docker runner

4. Switch to a 'runner' user

sudo su runner
newgrp docker

5. Create docker network

docker network create --subnet 10.1.0.0/24 exchanger-net

6. Docker login

  • Create a Personal Access Token in GitLab

  • Make sure to tick the read_registry permission scope

  • Create a reminder to update the PAT after expiration date, as once it expires you lose access for updates. https://git.boxexchanger.net/-/profile/personal_access_tokens

  • Login to docker read_registry

    docker login rg.boxexchanger.net

# Username: your_gitlab_username
# Password: your_gitlab_pat

7. Create required folders

mkdir -p /home/runner/api_server
mkdir -p /home/runner/api_server/config
mkdir -p /home/runner/api_server/public
cd /home/runner/api_server

8. Create your configurations (.env)

nano /home/runner/api_server/.env

Below example configuration .env Insert your variables PROJECT_NAME and API_URL

PROJECT_NAME=""
API_URL="https:///service/"
REDIS_URI="redis://exchanger-api-redis:6379/0"
UPLOADER_URL="http://exchanger-uploader-service:3013/"

9. Create nginx configuration for api

Create /home/runner/api_server/nginx_api.conf file with following contents

nano /home/runner/api_server/nginx_api.conf

Example nginx config.

map $http_upgrade $connection_upgrade {
    default upgrade;
    ""      close;
}

server {
    listen 3000;
    server_name default;

    location /service/ {
        proxy_pass http://exchanger-api:3010/;
        proxy_http_version 1.1;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
    }
    location /service/fs {
        alias /public;
    }
    location /ws/ {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_pass http://exchanger-api:3011/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_redirect    off;
    }

    access_log off;
    error_log  /var/log/nginx-error.log error;
    sendfile off;
    client_max_body_size 100m;
}

10. Create your docker-compose.yml

nano /home/runner/api_server/docker-compose.yml

Below example of docker compose file where you must change $VCS_NAMESPACE to your git group path for example bx4/project-name

x-logging:
      &default-logging

11. Execute credential mongo generation script

cd /home/runner/api_server
wget "https://git.boxexchanger.net/-/snippets/2/raw/main/init_db.js"
wget "https://git.boxexchanger.net/-/snippets/2/raw/main/generate_credentials.sh"
chmod +x generate_credentials.sh
./generate_credentials.sh

12. Initialize MongoDB

docker compose up -d exchanger-api-mongodb

13. Start API server

docker compose up -d

14. Get and remove initial admin credentials:

docker exec exchanger-api cat access.txt

  • remove access.txt

    docker exec exchanger-api rm access.txt
