Dockerizing Zombienet

[dudo50]

Issue Description

Currently, even after exposing endpoints my dockerized version of zombienet doesn't seem to allow to connect into PJS,

Zombienet starts fine

Steps to reproduce the issue

Steps to reproduce the issue

1. Running docker build
2. Starting docker
3. Clicking on zombienet endpoint

Describe the results you received

So when I click on Zombienet endpoint it stays on initiating in PJS and it never connects to zombienet

Describe the results you expected

How can I ensure, that zombienet endpoints are accessible?

Hi @dudo50, thanks for the feedback. Just to understand and try to reproduce. You are using zombienet native provider inside a docker container right? which url are you using for connecting to pjs?

Thanks again for the feedback!

[dudo50]

Thanks @pepoviola for quick reply - the "Direct link"

eg: │ Direct Link │ https://polkadot.js.org/apps/?rpc=ws://127.0.0.1:40895#/explorer

Yes, I use native

Thanks once again for your time!

Hi @dudo50, the Direct link will not work if you expose the ports in the container since is using 127.0.0.1 as ip instead of the ip of the container. You will need to publish the ports to allocate those on your host machine or change the ip to use the one from the container. Is something you see viable in your use-case?

Thanks!

[dudo50]

Thanks @pepoviola - Can you provide some guidance on how to do this?

It is definitely viable.

Thanks!

Thanks!

Great, yes. can you pointing here the repo/docker script you are using? Thanks!

[dudo50]

Sure @pepoviola ! Here is directly the link to dockerfile: https://github.com/paraspell-research/xcnft-pallet/blob/main/Dockerfile

Also here are my build and my run commands: docker build --platform linux/x86_64 -t polkadot-sdk-image:latest . docker run --network=host --platform linux/x86_64 --rm -it polkadot-sdk-image:latest

Thanks again!

Hi @dudo50, can you use something like

[relaychain]

default_command = "../target/release/polkadot"
default_args = [ "-lparachain=debug" ]

chain = "rococo-local"

  [[relaychain.nodes]]
  name = "alice"
  rpc_port = 9910

  [[relaychain.nodes]]
  name = "bob"
  rpc_port = 9911

  [[relaychain.nodes]]
  name = "charlie"
  rpc_port = 9912

  [[relaychain.nodes]]
  name = "dave"
  rpc_port = 9913

[[parachains]]
id = 1000

  [parachains.collator]
  name = "parachain-A-1000-collator01"
  command = "../target/release/parachain-template-node"
    args = [
        "-lparachain=debug,xcm::process-message=trace,xcm::execute=trace,xcm::process=trace"
    ]
  rpc_port = 9920

[[parachains]]
id = 1001

  [parachains.collator]
  name = "parachain-A-1001-collator01"
  command = "../target/release/parachain-template-node-two"
  args = [
        "-lparachain=debug,xcm::process-message=trace,xcm::execute=trace,xcm::process=trace"
    ]
  rpc_port = 9921

and the when you run use

  docker run --network=host --platform linux/x86_64 -p 9910-9913:9910-9913 -p 9920-9921:9920-9921 --rm -it polkadot-sdk-image:latest

So you publish the fixed ports for pjs

Thanks!
