☸️Kubernetes support improved by a ton.
↪ Proxy for container environments.
🌓Dark mode is now supported.
💻Kubectl integration.
💾GitOps integration.
🌸UI improvements.
🔐HTTPS support.
The new UI has been redesigned to reduce clutter and be more intuitive, It's now much easier to navigate inside Portainer.
Kubernetes users should feel it very comfortable.
✅Lightweight GitOps integration
Introduced a lightweight GitOps engine: it enables users to employ 'entry level' CD automation' (no expertise needed).
This allows a user to configure the app's updates:
- automatic
- poll-based
- push-based (webhooks)
✅Forced Redeployment
It allows enabling an enforcement setting when deploying an application from Git
This makes sure any external change to the application is always overridden by the definition stored in Git.
✅Change Window Settings
Now you can specify a change window on specific environments to prevent automatic updates from happening outside of the changes window.
✅Kubectl Shell
Kubectl natively integrated into Portainer
This helps users troubleshoot Kubernetes apps without having to leave the Portainer UI
It also allows expert users to use advanced Kubernetes features and functions not yet supported inside Portainer.
✅Proxy for container environments
Portainer can now be used as a secured authenticated proxy into 3rd-party container environments.
This allows Platform/DevOps engineers to integrate Portainer with 3rd-party CI/CD tools to build secure automated delivery workflows.
✅Helm Charts support
Now you can deploy software provided by your ISV or any tool vendor inside a K8S environment.
By supporting Helm you can easily register application repositories inside Portainer.
Then you can deploy any application listed under these repositories.
✅Custom Templates
Useful to share/re-use app manifests across Kubernetes environments.
This will enable advanced Kubernetes users to create application packages they will be able to share with everyone.
✅Kubernetes private registry support
You can now deploy applications that are hosted on any private registry supported by Portainer.
This also introduces a revamp of the registry access management experience to make it more consistent across Docker and Kubernetes.
🔐HTTPS support
HTTPS support goes hand in hand with our container environment proxy to make sure that communications between any 3rd party or external tools and Portainer are secured.
❌Advanced Mode removal
UI realigned the UI around Form vs Manifest deployment.
This is to make more sense of the deployment workflow.
🌓Dark Mode
One of the Portainer community's most requested features!
You can now set your theme on any user in the account settings.
In this release, Portainer will ship with:
- experimental support for a dark theme
- high-contrast theme.

· What is a Blockchain
It's a growing list of records (blocks)
The Blocks are linked together using cryptography.
It's described as an immutable data storage:
- trustless
- fully decentralized
- peer-to-peer
- immutable
It's spread over a network of participants (nodes)
· Blocks
They contain:
- a cryptographic hash of the previous one.
- a timestamp + transaction data.
The timestamp proves that the transaction data existed when the block was published in order to get into its hash.
It was 2015. I was curious and started researching. I didn’t have any online presence at the time so I was just studying on my own trying to figure out how it worked.
Now I know many Docker Captains, like @BretFisher@mikesir87 , @GianArb!
What is your favorite Docker command?
This is a nice question! I think I will go with “docker compose up –build”, this is exactly what you need to test your command on your development environment.
Resources that link Blockchain to Docker🐳
· Create Ethereum Dapp with React + Docker
· Deploying Blockchain Applications with Docker
· Docker usage in Blockchain
· Docker in Blockchain Projects
· Go Ethereum (Go implementation of Ethereum protocol)
Blockchain blocks hold batches of valid transactions into a Merkle tree.
Basic concepts to study how they work:
· Hash
· Sign
· Genesis Block
· Fork
· Consensus Algorithm
· Peers and the database
· History
· New entries
· Redundant Computation
/thread
Hash
A hash is a math function that converts an input of arbitrary length into an encrypted output of a fixed length.
· Each block includes the cryptographic hash of the previous, linking the two.
·Blocks are hashed and encoded.
Digital signature
A digital signature is an auth mechanism.
It enables the creator of the message to attach a code that acts as a signature.
