This blog is the first in a two-part series.We’ll talk about the
challenges of defining Web3 plus some interesting connections
between Web3 and Docker. Part two will highlight technical
solutions and demonstrate how to use Docker and Web3 together.
We’ll build upon the presentation, “Docker and Web 3.0 — Using Docker
to Utilize Decentralized Infrastructure & Build Decentralized
Apps,” by JT Olio, Krista Spriggs, and Marton Elek from
DockerCon 2022.However, you don’t have to view that session before

When you need to back up, restore, or migrate data from one Docker
host to another, volumes are generally the best choice.You can stop
containers using the volume, then back up the volume’s directory
(such as
/var/lib/docker/volumes/<volume-name>).Other
alternatives, such as bind mounts, rely on the
host machine’s filesystem having a specific directory structure
available, for example /tmp/source on UNIX systems
like Linux and macOS and C:/Users/John on Windows.
Normally, if you want to back up a data volume,
Since containers are a primary means for developing and deploying
today’s microservices, keeping them secure is highly important.But
where should you start?A solid container security workflow often
begins with assessing your images.These images can contain a wide
spectrum of vulnerabilities.Per Sysdig’s latest
report, 75% of images have vulnerabilities considered either
highly or critically severe. There’s good news though — you
can patch these vulnerabilities!And with better coordination and
transparency, it’s possible to catch these issues in development
before they impact your
In this guest post, David Balakirev, Regional CTO at Adnovum,
describes how they show the benefits of container technology based
on Docker.Adnovum is a Swiss software company which offers
comprehensive support in the fast and secure digitalization of
business processes from consulting and design to implementation and

Everybody wins when solution providers focus on providing value and
not on the intricacies of the target environment.This is where
containers shine. With the wide-scale adoption
The MERN Stack is a fast growing, open source JavaScript stack
that’s gained huge momentum among today’s web developers.MERN is a
diverse collection of robust technologies (namely, Mongo, Express, React, and Node) for developing scalable
web applications — supported by frontend, backend, and database
components.Node, Express, and React even ranked highly among
most-popular frameworks or technologies in Stack Overflow’s
2022 Developer Survey.
