Privat network using Docker

General
1

Hi Everyone,

So my current configuration:

Raspberry pi nodes running ubuntu containers in host mode (11 Rpi so 1 relay node and 10 non relay nodes) No ports exposed and not sure if needed.

Each container has algorand and needed dependency installed.
On the relay nodes created a private network and made changes to the “Endpoint:” showing the host ip and a port .
{ “GossipFanout”: 1, “NetAddress”: “192.168.1.147:7447”, “EndpointAddress”: “127.0.0.1:0”, “DNSBootstrapID”: “”, “EnableProfiler”: true}

Started the private network with that particular relay node (goal network start -n ~/net1/Primary -r ~/net1)

Copied the genesis.json file to the other containers and then started those nodes(goal node start -d /root/net1/Node -p 192.168.1.147:7447) .

One confusion do we copy the genesis.json or the folder Node which was created with the private network ?

Errors or warnings:

Every time the relay node starts and then it shutdown after some time
Cannot contact Algorand node: Get http://127.0.0.1:43653/v2/status: dial tcp 127.0.0.1:43653: connect: connection refused.

Am I doing something wrong . Any step which is missed out? the private network works at times before but now its causing this issue

The relay needs to open ports. See https://developer.algorand.org/docs/reference/node/config/

Hello,

I am interested in running a private network to have a private test net. Is there any documentation that explains technical details to run the Algorand in a private setting?

Thank you
Kadir.
