How to run SPN and publish own blockchain here?

[silverstr89]

Describe the bug Hello everyone

i totally do not understand how to work with SPN

I cloned this repo, and then started as in readme and i got

🛠️  Building proto...
📦 Installing dependencies...
🛠️  Building the blockchain...
💿 Initializing the app...
🙂 Created account "user1" with address "cosmos1gsj3kuq0pljhlrcecvyuz6l4vgdn5umcsa59my" with mnemonic: "analyst thank planet attack immense become stage pride point obey stuff rescue loan cushion ready alert ancient strike quantum boil ivory history flat fun"

🌍 Tendermint node: http://0.0.0.0:26657
🌍 Blockchain API: http://0.0.0.0:1317
🌍 Token faucet: http://0.0.0.0:4500

ok, what next? is there SPN already started?

i trying connect to my SPN

ignite n chain list --spn-node-address "http://my IP:26657"

and getting connect: connection refused, but of course my server is available!

i trying to publish blockchain in SPN

ignite network chain publish or whatever --spn-node-address "http://my IP:26657" and getting connection refused

basically my idea is make similar with https://www.youtube.com/watch?v=DhciTJHxvAY&t=46s , but for ignite. and i cannot do that

is there any chance someone could help me to run my own blockchain?

To Reproduce Steps to reproduce the behavior: described above

Please provide output of commands

• spn version not provided
• go version go version go1.17.13 linux/amd64
• uname -a Linux validator-4 5.13.0-1022-aws #24~20.04.1-Ubuntu SMP Thu Apr 7 22:10:15 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

Hey, the flow is correct, when running the chain on your machine, you should be able to connect with Ignite CLI to it.

ignite network chain publish or whatever --spn-node-address "http://my/ IP:26657" and getting connection refused

On the same machine, you can connect with

ignite n chain list --spn-node-address "http://0.0.0.0:26657"

If you run spn on your server and want to access it, you need to open port 26657 on your machine

We also have a config_2.yml using different ports for spn that is compatible with Ignite CLI --local flag.

If you serve spn from config_2.yml:

ignite c serve -r -c config_2.yml
Cosmos SDK's version is: stargate - v0.46.1

You can use on the same machine the --local flag to interact with the chain

ignite n chain list --local

Please beware that spn is under active development and the pulled version from develop may not be compatible with the release version of the Ignite CLI

@lubtd thank you so much! can i mount blockchain from private repo?

i trying to use source https://github.com/privaterepo but it requires authorisation and i don't have idea how to authorise

[silverstr89]

@lubtd i don't know why. this now running, but i cannot connect remotely to this machine

for example, my spn work at http://someIp:26661, and on local host it works

when i trying to connect from other machine ignite n chain list --spn-node-address "http://someIp:26661" i getting connection refused. server is available

[lumtis]

We currently can't use the network with private repo. And we shouldn't with the public Ignite Chain.

But it may be a good idea to allow to on a local network for experimentation. Using Github token, we can open an issue and do investigation for this

[silverstr89]

@lubtd what could you say about second question? why i cannot connect to the port of spn network?

[lumtis]

when i trying to connect from other machine ignite n chain list --spn-node-address "http://someip:26661/" i getting connection refused. server is available

When you say that server is available, does it mean you can access http://someip:26661/ from a browser?

[silverstr89]

i mean some ip is working, but when i trying connect to 26661 it is refused. other ports working ok when i ping them

[lumtis]

Seems like to be related to your server firewall or something. Is it doing the same for every port? You can change the RPC port with the value validators[x].config.rpc.laddr in your config yml file

validators:
- name: alice
  bonded: 100000000uspn
  app:
    api:
      address: :1319
    grpc:
      address: :9094
    grpc-web:
      address: :9095
  config:
    p2p:
      laddr: :26660
    rpc:
      laddr: :26661
      pprof_laddr: :6062

it is related to https://github.com/tendermint/spn/issues/966
