Docker container for BTDEX

This project takes the standalone BTDEX application and transforms into portable, web-accessible container using Docker and KasmVNC base image.

---

BTDEX is a decentralized exchange (DEX) system running on the Signum blockchain.

---

Quick Start

NOTE: The Docker command provided in this quick start is given as an example and parameters should be adjusted as needed.

First, clone this repository:

git clone https://github.com/furritos/docker-btdex.git
cd docker-btdex

Launch the BTDEX Docker container with the following, Linux and PowerShell compatible, command:

docker run -d \
  --name=container-btdex \
  -v ${pwd}/config:/opt/btdex/.config \
  -v ${pwd}/plots:/opt/btdex/plots \
  -v ${pwd}/cache:/opt/btdex/cache \
  -p 3000:3000 \
  -p 3001:3001 \
  furritos/docker-btdex

For macOS, the following command will need to be executed (note the capitalized PWD):

docker run -d \
  --name=container-btdex \
  -v ${PWD}/config:/opt/btdex/.config \
  -v ${PWD}/plots:/opt/btdex/plots \
  -v ${PWD}/cache:/opt/btdex/cache \
  -p 3000:3000 \
  -p 3001:3001 \
  furritos/docker-btdex

Finally, take your favorite web browse and open http://localhost:3000/. For HTTPS, use https://localhost:3001,

Please refer to this Get Started page for more information on using BTDEX.

Docker Basic Usage

docker run [-d] \
  --name=container-btdex \
  [-v <HOST_DIR>:<CONTAINER_DIR>[:PERMISSIONS]]... \
  [-p <HOST_PORT>:<CONTAINER_PORT>]... \
  [-e <VARIABLE_NAME>=<VALUE>]... \
  furritos/docker-btdex

Parameter	Description
-d	Run the container in the background. If not set, the container runs in the foreground.
-v	Set a volume mapping (allows to share a folder/file between the host and the container). See the Data Volumes section for more details.
-p	Set a network port mapping (exposes an internal container port to the host). See the Ports section for more details.
-e	Pass an environment variable to the container. See the Environment Variables section for more details.

Data Volumes

The following table describes data volumes used by the container. The mappings are set via the -v parameter. Each mapping is specified with the following format: <HOST_DIR>:<CONTAINER_DIR>[:PERMISSIONS].

Container path	Permissions	Description
/opt/btdex/.config	rw	BTDEX configuration artifacts directory
/opt/btdex/cache	rw	Presumably, high-speed storage to aid in plot file creation
/opt/btdex/plots	rw	Plot files to be used for mining

Ports

Here is the list of ports used by the container. They can be mapped to the host via the -p parameter (one per port mapping). Each mapping is defined in the following format: <HOST_PORT>:<CONTAINER_PORT>. The port number inside the container cannot be changed, but you are free to use any port on the host side.

Host Port	Container Port	Mapping to host	Description
9000	9000	Optional	Port used by BTDEX to expose API endpoints. More information can be found over at BTDEX - API section.

Changing Parameters of a Running Container

As can be seen, environment variables, volume and port mappings are all specified while creating the container.

The following steps describe the method used to add, remove or update parameter(s) of an existing container. The general idea is to destroy and re-create the container:

1. Stop the container (if it is running):

docker stop container-btdex 

2. Remove the container:

docker rm container-btdex 

3. Create/start the container using the docker run command, by adjusting parameters as needed.

NOTE: Since all application's data is saved under the /opt/btdex/.config container folder, destroying and re-creating a container is not a problem: nothing is lost and the application comes back with the same state (as long as the volume mapping of the /opt/btdex/.config folder remains the same).

Docker Image Update

Because features are added, issues are fixed, or simply because a new version of the containerized application is integrated, the Docker image is regularly updated. Different methods can be used to update the Docker image.

The system used to run the container may have a built-in way to update containers. If so, this could be your primary way to update Docker images.

An other way is to have the image be automatically updated with Watchtower. Whatchtower is a container-based solution for automating Docker image updates. This is a "set and forget" type of solution: once a new image is available, Watchtower will seamlessly perform the necessary steps to update the container.

Finally, the Docker image can be manually updated with these steps:

1. Fetch the latest image:

docker pull furritos/docker-btdex

2. Stop the container:

docker stop container-btdex 

3. Remove the container:

docker rm container-btdex 

4. Create and start the container using the docker run command, with the the same parameters that were used when it was deployed initially.

unRAID

For unRAID, a container image can be updated by following these steps:

1. Select the Docker tab.
2. Click the Check for Updates button at the bottom of the page.
3. Click the update ready link of the container to be updated.

Accessing the GUI

Assuming that container's ports are mapped to the same host's ports, the graphical interface of the application can be accessed via:

• Unsecured: http:/localhost:3000
• Secured: https://localhost:3001

Shell Access

To get shell access to the running container, execute the following command:

docker exec -ti container-btdex bash
