Docker container for Magnet Wallet / Masternode.Hi, I am creating basic Dockerfiles to build and host wallets / masternodes.
Why?
With this containers you are able to have multiple wallets / masternodes on the same VPS.
Each container runs in its own environment and does not effect any services on the host system or other containers.
People running multiple masternodes rent for each a VPS, with this you can have multiple masternodes on the same VPS.
Read up on Docker @
https://www.docker.com/what-container if you interrested.
I will guide you through a basic installation on a Ubuntu 17.10 OS.
We will create a docker image with Alpine Linux as base and compile the latest Advance Protocol daemon on it.
Login (ssh) into your VPS:
# Lets upgrade all packages.
> apt-get update
> apt-get upgrade -y
# If you are on a VPS with low RAM and no swap space, lets create one
> fallocate -l 2G /swapfile
> chmod 600 /swapfile
> mkswap /swapfile
> swapon /swapfile
> cp /etc/fstab /etc/fstab.bak
> echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
# Install Docker
> apt-get install apt-transport-https ca-certificates curl software-properties-common -y
> curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
> apt-key fingerprint 0EBFCD88
> add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu zesty stable"
> apt-get update
> apt-get install docker-ce -y
# Create a directory and copy paste the the content into the Dockerfile
> mkdir -p magnetBuild
> cd magnetBuild
> nano Dockerfile
# save the file: CLTR+X

# Create the image, this will take some time!

# After the image is created, start it with an interactive shell inside
# You can repeat this step and create multiple containers now, make sure to use different ports & names
# -it = interactive
# -p = map ports from host to container

# Inside of the docker container, we will start the magnetd daemon for the first time

Thats it for now, hope this helps some of you who want to run multiple / sandboxed wallets on the same machine.
Ofc, you can do more with docker images
+ make the start full automatic
+ restart in case daemon crashes
+ send emails on events
+ basically limit is what you imagine!!
I build docker images for other coins as well. For questions, you can find me in the discord channel.
If you found this useful buy me a coffee =)
