Getting Started


Supported OS#

  • Ubuntu
  • RHEL
  • Centos
  • Ferdora
  • Most Debian / RPM based OS which nodejs supports

Node Versions#

DatatruckerNode Version
1.0.xv12.x , v14.x

If your interested in the Kuberenetes version : redirect to the link : Running on Kubernetes

Backend database build#

  • Datatrucker API server requires a Postgres Database.
  • A DB userid can connect to the above database with read/write access on the database
  • Note: if you are sharing the same Postgres instance with other apps, Datatrucker requires a dedicated/clean DB on that postgres instance.

Datatrucker API / UI Server Dependencies#

  • Two Ports are required ( 1 for API and 1 for UI , if necessary you can put them on separate machines )
  • Servers have access to or an equivalent NPM proxy/registry which all for npm install
  • The server has the following users defined
    • A privileged Linux user-id to install globally scoped dependencies or temporary sudo access ( only required during installation )
    • A Linux regular user-id to run node-js servers
  • Note: Download the software assumes accepting the License
  • Have a database setup, with a user-id to use as a backing store. See the next section for supported databases

Supported backends databses#

  • Postgres
    • Adding more database soon

Install the API server#

NPM dependencies#

# Verify if node is installed
-> node -vv12.xxxxx or v14.xxxx or higher

Create a folder to host the server#

  1. SSH into the API VM (# For representation we use the user id trucker, this can be any user and for representation we use the home directory as /home/trucker)
  2. create folder location -> mkdir /home/trucker/server
  3. move into the path -> cd /home/trucker/server
  4. download the source code from latest release from here
  5. once unzipped it should look like this
    [email protected]:~/server$ ls -la /home/trucker/server/    total 28    drwxrwxr-x  6 trucker trucker 4096 Apr 26 09:54 .    drwxr-xr-x 32 trucker trucker 4096 Apr 26 09:52 ..    drwxrwxr-x 11 trucker trucker 4096 Apr 30 17:07 datatrucker_api    drwxrwxr-x  4 trucker trucker 4096 Apr 30 17:07 datatrucker_ui    .    .    .
  1. cd into datatrucker_api

Install global dependencies#

1) NPM global dependencies ( may require privileged user or sudo)#

npm install --registry '' -g node-gyp pm2 knex   [ May require sudo to install global dependencies ]
response: should look like this.+ [email protected]+ [email protected]+ [email protected]added 529 packages from 327 contributors in 15.832s

2) Install the application dependencies of the API server#

#move into the path where the server is unzippedcd ~/server/datatrucker_api/app
#Make sure you have the package.json in the folder~/server/datatrucker_api/app$ ls package.json package.json
# install npm dependencies npm install --registry '' 

3) Basic configuration#

  1. Open the file datatrucker_api/app/config/server.config.json

    Edit the following port: prefer to use a port above 1024, so the server can be run without a privileged user ( default 8081)

  2. Configure the database connection in datatrucker_api/app/config/db.config.json

    {          "type": "pg",          "host": "localhost",          "port": 30001,          "username": "testuser",          "password": "password",          "database": "userdb",          "PoolMin": 300,          "PoolMax": 600    }

4) Initialize the Database#

#move into the path where the server is unzippedcd /home/trucker/server
#move into the App foldercd datatrucker_api/app
#Initialize the databasenpm run migrate
Response Sample:Using the environment: productionAlready at the base migrationUsing the environment: productionBatch 1 run: 8 migrations

5) Start the API Server#

    #move into the path where the server is unzipped    cd /home/trucker/server
    #move into the App folder    cd datatrucker_api/app
    #start the server    npm run trucker
    #you should see the pm2 start    # to check status use    pm2 status
    #to check realtime monitor use    pm2 monit
    ##Troubleshooting    run the commands to stop the app    pm2 stop all    pm2 delete all    Check the logs folder to see what happened 

6) Initialize the admin user#

Check the health#
    curl --location --request GET 'http://<URL>:<port>/api/v1/statuschecks/healthcheck'
    Response:    {        "reqCompleted": true,        "date": "2021-01-02T15:28:18.900Z",        "reqID": 1,        "data": {            "db": true,            "cache": true,            "dbinitialized": false        },        "serverID": "ServerHandler"    }
Check the initialization status#
    curl --location --request GET 'http://<URL>:<port>/api/v1/statuschecks/is-intialized'
    Response:    {        "reqCompleted": true,        "date": "2021-01-02T15:28:02.524Z",        "reqID": 1,        "data": {            "isIntialized": false        },        "serverID": "ServerHandler"    }
Initialize the server#
    curl --location --request POST 'http://<URL>:<port>/api/v1/statuschecks/intialize' \    --header 'Content-Type: application/json' \    --data-raw '{        "username": "godmode",       -> you admin user         "password": "[email protected]",     -> your password    }'
    Response:    {        "reqCompleted": true,        "date": "2021-01-02T15:31:21.698Z",        "reqID": 1,        "data": "Admin user created",        "serverID": "ServerHandler"    }
Check the health#
curl --location --request GET 'http://<URL>:<port>/api/v1/statuschecks/healthcheck'
    Response:    {        "reqCompleted": true,        "date": "2021-01-02T15:35:48.112Z",        "reqID": 1,        "data": {            "db": true,            "cache": true,            "dbinitialized": true        },        "serverID": "ServerHandler"    }

7) Configure the UI Server#

Note: The UI server is a development utility, this needs to exist on the developers laptop pointing to an API server .

Note: If you want to start UI in a different server
the following sections need to be executed on the different server
1) NPM dependencies
2) Create a folder to host the server

Go into the UI folder

#move into the path where the server is unzippedcd /home/trucker/
#move into the UI foldercd datatrucker_ui/app
#edit the file datatrucker_ui/.envedit "REACT_APP_APIURL" to point to the API URLedit "UI_PORT=" to point to the port of the UI
#install global dependencies (may require sudo privileges )npm install --registry '' -g pm2 
#Install UI dependenciesnpm install
#start the servernpm run start
#Congratulations, you can now access the installation via the browser on http://<uiserver>:<uiport>#and have finished the quick start guide.
#For production hardening/ssl move into hardening guide.
