# How to use OpenOpcUa Docker image

## Overview

This docker image is based on Debian linux/amd64. It contains an OpenOpcUa (OOUA) demo. The demo simulate a tank with a bunch of methods and variables.

There is a Tank01 instance (UAObject) of TankType (UAObjectType). You can play with method StartPump, StopPump, Drain, GetCurrentLevel, etc.

The server is listening on port 2407.

## Introduction

The docker image is hosted on a public Docker Repository on Docker Hub. Do you can pull it and use it as long as you want.

## Requirements

1) A valid docker account

2) Docker Desktop installed [Download here](https://desktop.docker.com/win/main/amd64/Docker%20Desktop%20Installer.exe?utm_source=docker&utm_medium=webreferral&utm_campaign=dd-smartbutton&utm_location=module)

3) An OPC UA client to connect to the server 

## How to use it ?

1) Get the image from Docker hub from a command line

2) Start a commande line (CMD)

3) To get the image from Docker hub. 

    From the command line enter the following command: 

      >docker pull michel4ce/oouasimulationtank:0.0.1

4. To run the image

    From the commande line enter the following command:

      >docker container run -dp 2407:2407 -t michel4ce/oouasimulationtank:0.0.1

## Verify the container was receive properly.

Using Docker Desktop go to the Images list. You shall see something like this :

## Verify the the image is runnning properly.

 ![Container bound!](http://www.openopcua.org/redmine/attachments/download/3843/OOUARunningContainerInspectTab.PNG "Runnig container bound")

2. From the Log tab. you can see that the server is running listening on :

    >opc.tcp://localhost:2407/DemoTank

![Running!](http://www.openopcua.org/redmine/attachments/download/3842/OOUARunningContainerLogTab.PNG "Running")

## Connect using an OPC UA client

Here an example with UAExpert from Unified Automation. But you can use any client.
