This repository contains the Dockerfile and scripts to build a HTMLCoin node version 2.5 Docker image on Ubuntu 18.04 and 20.04.

Clone this repository with

git clone https://github.com/ilorivero/htmlcoin_docker.git

cd ./htmlcoin_docker/Ubuntu_18.04/
docker build -t htmlcoin .

As there is no bitcoin repository for Ubuntu 20.04, I did some workarounds to make it work. Added the bionic repository, repository keys and configured time zone for unattended install.

cd ./htmlcoin_docker/Ubuntu_20.04/
chmod 777 tzscript.sh
docker build -t htmlcoin .

This will preserve the blockchain data.

docker volume create --name=data

docker run -d --rm --name htmlcoin -v data:/root/.htmlcoin/ htmlcoin 

To check if the htmlcoin container is running:

 docker exec -i -t htmlcoin /bin/bash

You should be prompted with the Ubuntu command line.

root@0670472b9f64:/HTMLCOIN#

Check the Ubuntu version:

lsb_release -a

You shoud get something like this:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04 LTS
Release:        20.04
Codename:       focal

To check if HTMLCoin daemon is running, call the htmlcoin-cli app with --getinfo parameter:

htmlcoin-cli --getinfo

The result should be something like this:
