ANP with 2nd walkthrough video

In this video I share with the viewer some of the experiences I have had with my time in the Friends and Family testnet period for cardano-node and walk the viewer through making a node certificate, creating staking keys and as bonus contents we look more into docker swarm, pro’s and con’s of docker containers for cardano-node and community scripts.

ADA North Pool will mentor two scandinavian pool operators for the family and friends testnet

ADA North Pool is quite honored to invite two Scanadinavian pool operators that have been around for the ITN and that have the technical skills and hardware to get going into the family and friends testnet full speed ahead. It was not an easy decicion to make and actually weighted quite heavily on me. But I think for the long run the best I can do is .. do what I do best and know best. I want to encourage my own region and that we have adoption here for Cardano so I decided that me as a Norwegian pool operator should try to encourage scandianvian adoption. That definitively does not mean I would not help other pool operators far from it – I simply also want to see Cardano thrive in my own backyard here in Scandinavia.

So without further ado we decided to go with AHL and JAWS1. You can find them on twitter as well: https://twitter.com/JawsAda https://twitter.com/olaahlman

Welcome aboard lads and lets show them that viking spirit !

PS: We are also encouraging a Cardano Scandinavian Pool Operators collaboration (CSPO) so might hear more from this space going forward ūüôā

ANP walkalong video for ff testing

In this video I share with the viewer some of the experiences I have had with my time in the Friends and Family testnet period for cardano-node and walk the viewer through building a node, configuring it, making transactions and finally also looking at docker images as a method of deployment for cardano-node.

ANP adds monitoring of cardano-node block producer and docker relays

If you want to follow live the progress of my nodes and relays you can find the monitoring links in the menu now where one is named “Monitor Cardano-node” and the other is named “Monitor Docker-relays”

ANP creates cardano-node scripts for learning purposes

They say one of the best ways to learn how something truly works is to build it from the ground up. So I took that to heart and decided to build some scripts instead of using some of the other great scripts out there. And I could not resist putting in some ASCII for ANP logo in there as well ūüôā


Create address and .vkey .skey:

ANP joins friends and family testnet and adds hardware based encryption for cold staking keys

Ada North Pool had the great honor of being asked to join the friends and family testnet. The TLDR is the progress is great. Overall the experience has been great and documentation, features and overall experience is shaping up well in the opinion of this pool operator.

We also added a hardware encryption usb drive in preperation of cold staking key storage.

Fingerprint identifying 256-bit AES hardware encryption usb.
View of a core node and a relay as of today 14th May.

The nodes come prebuilt with a lot of features that can be enabled. For example the EKG view that you can set to a port on your localhost.

EKG view of cardano-node with a lot of data.
With a Prometheus exporter built into the node it is really easy to setup Grafana data as well.

ANP New server/node structure overview and update on [email protected]

An overview of the latest node structure for Ada North Pool (ANP).
Attribution for logos used: Computer Vectors by Vecteezy

To end the testnet with a bang we have upped our efforts even more. We added two Germany based xeon 4core computers on 1gb fibers at one of the datacenter of Hetzner where we are now both [email protected], practicing with cardano-node swarm (manager/[email protected]) and also adding block propegation for jormungandr to improve our chances of winning slot battles. For our home servers we have a local swarm on its own network (lan based) for the cardano-core that is in touch with the cardano relay nodes (in ip addresses relay1.adanorthpool.com and relay2.adanorthpool.com and also the remote servers @ relay3 and relay4) and thus should work fine even if one of the internet falls down. We also have full UPS backup in both the home servers and in the datacenter. I think we are now on a path to become far more secure in our operations even in the event of internet failures or power outages.

[email protected] is going solid with participation previously by the whole ANP family of computers. Onwards we will be using ANPLAPTOP (4 core) ANPSERVER2 (its a 12 core so have idle capacity for this) Both the ANPHERTZNER servers (4 core) + ANP FAMILY computers that are 8 core and 4 core and with GPU computation as well.

We are currently participating with a good deal of computation for the Cardano team. Stats can be viewed @ https://stats.foldingathome.org/team/244483
Main jormungander server with a pool and 6 nodes.
The main server also hosts a core cardano-node (2nd network lan) and a cardano-node relay (internet)
ANP server 2 hosting 4 cardano-node relays. Server is also [email protected] on light setting.
ANP Hertzner servers the two cardano-node relays are up and running. The jormungandr propagators one is up and other is boostraping soon to be up as well. Both ANP Hertzner servers also run [email protected] on light to help support the cause.

     * 2x HDD SATA 3,0 TB Enterprise
     * 4x RAM 4096 MB DDR3 ECC

ANP ADDED FIRST CARDANO-NODE TESTENET DOCKER SWARM CLUSTER

Visualizer container showing the manager (ANPSERVER2) and the worker (ANPLAPTOP) both having cnodes (cardano-node images I have made that you can find in the repostiory here https://hub.docker.com/repository/docker/eysteinh/cnode.

After quite some work this weekend we have some of the basics of docker and managed to make our own docker swarm based on an in-house composer.yaml file that you can find an edited version of you can use as an example for yourself here https://gist.github.com/Willburn/5c40e6b05010623ad8c596bcedc0c19b

The docker image itself you can find the Dockerfile for here: https://github.com/Willburn/docker

Here is the local ANPSERVER2 Nodes with the terminal output to verify that indeed they work inside a swarm cluster

Here you can see all 3 computes (2 servers 1 laptop) in action with cardano nodes running initiated from the swarm manager:

ANPLAPTOP running 2 cardano nodes
ANPSERVER2 running 4 cardano nodes
ANPSERVER running 1 cardano node

And here is the whole operation center in one view:

ANP SERVER 2 RUNNING CARDANO-NODE DOCKER IMAGES

After quite some work we now have started to learn to use docker images. This will allow easier deployment across servers for the future and helps isolate any nodes having problems.

For the community you can find a dockerfile on github https://github.com/Willburn/docker and I hope in the future I can write a guide for the community on how to get up and running docker image based cardano-nodes.
