DK NodesNODE FROM NESA | FULL MANUAL!
Hello fellows! We’ve prepared an all-in-one guide for you that will allow you to set up a NESA node in the easiest way possible! Hello fam! 1. First of all, purchase a server from AEZA, Contabo or Spacecore. Server specifications: • 6 vCPU Cores • 16 GB RAM • 400 GB SSD 2. Set up the server on your PC. Log in using the command root@ip. But before that, we recommend securing your server. Read more in our article.PreparationCreating a Token1. Go to Hugging Face and sign up.2. Create a token by ...
DK NodesWhy Securing Your Server Is Important and How to Do It
In today’s digital world, securing your server is a must, especially if you’re running nodes for blockchain networks or other distributed systems. In this guide, we’ll break down why server security is so important and how to keep things safe on Ubuntu (Linux), including how to generate SSH keys for secure access.Why Server Security Is a Big DealProtecting your data:Servers hold a lot of sensitive stuff — like user info, financial data, and company documents. A data leak could lead to major f...
DK NodesThe Importance of Using Different Ports When Running Multiple Nodes on One Server
In today’s world of blockchain networks and dApps, a lot of people run multiple nodes on one server. But there’s one important thing to keep in mind with this setup — each node needs its own port. It might seem like a small detail, but properly setting up ports is crucial for keeping things stable, secure, and scalable. Let’s break down why using different ports for each node matters and how it affects your server’s performance.Ports and Their Role in Network InfrastructureA port is a communi...

Docker is a platform that allows you to run applications in isolated containers. A container is a lightweight, standalone unit of software that includes everything needed to run an application: code, libraries, system tools, and settings. Essentially, Docker provides a way to create a universal “package” for applications that work consistently on any system where Docker is installed.
Here are some of the essential commands for working with Docker:
docker pull: Download an image from Docker Hub or another repository to your local machine.
docker run: Runs a container based on an image. This command creates and starts a new container.
docker run -d -p 80:80 nginx
Here, -d means "run in the background," and -p 80:80 maps ports from the container to the host system.
docker ps: Shows a list of all running containers. Adding the -a flag will also display stopped containers.
docker ps -a
docker stop and docker start: Stop and start containers, respectively.
docker stop <container_id> docker start <container_id>
docker rm: Deletes a stopped container.
docker rm <container_id>
docker rmi: Removes an image from the local repository.
docker rmi <image_id>
docker exec: Runs a command inside a running container, which is useful for interacting with the application within the container.
docker exec -it <container_id> /bin/bash
The flags -it enable interactive mode with a terminal session.
Docker is often used for deploying blockchain nodes in various projects. Here’s why:
Environment isolation: containers allow for complete isolation of the environment where the node is running. This is very convenient since blockchain nodes can have different dependencies (libraries, software versions) that might conflict with each other or with the host system.
Simplified setup and deployment: with containers, setting up a node is reduced to a single command (docker run). There's no need to manually configure the environment or download dependencies.
Ease of updating and scaling: updating a node can be done with just a few commands — simply stop the old container, download the new image, and start it. Scaling is also simplified, as deploying an additional node is just a matter of running another container.
Cross-platform compatibility: using Docker, you can run nodes on different operating systems (Linux, Windows, macOS) without needing to configure the environment for each.
Stability and predictability: Containers ensure that applications run the same way regardless of the environment. If something works in a container on your local machine, it will work the same on the server.
Resource efficiency: Unlike virtual machines, containers are “lighter” since they use the host system’s kernel and don’t require a separate operating system.
Fast deployment: Since Docker containers start almost instantly, you can quickly deploy new instances of an application or update existing ones.
Process automation: Docker easily integrates with CI/CD processes (continuous integration and delivery), allowing for automation of application deployment and updates.
Docker has become an indispensable tool for developers and DevOps engineers, enabling efficient management of applications and their environments, particularly in blockchain and node contexts. If you work with nodes, using Docker can greatly simplify your life and make deployment and update processes faster and more reliable.

Thanks for your attention, node runners!
