Connect Ganache GUI to Ganache CLI?

[siman]

Is it possible to connect Ganache GUI to Ganache CLI? So far I see that they don't work together :(
What I am trying to achieve: run Ganache CLI on a server in a background and connect to it with GUI on my local laptop.

[n1c01a5]

change the port 7545 => 8545 in the parameters and restart Ganache

[nickysemenza]

This isn't working for me, Ganache GUI is just starting up a server on 8545 as well...

[kowsheek]

They have to have the same networkId. You can change the networkId of ganache-cli using the -i flag. If you have the GUI running though, you won't need the CLI.

[nickysemenza]

Hmm it's still not working for me.
I have Ganache configured like so:

and then i'm running ganache-cli --deterministic --networkId 999999 inside a docker container on the same computer, and exposing 8545. I can connect to ganache-cli over rpc using Mist/etc running outside of docker, so the communication is working.

Ganache shows this in the logs

[3:41:13 PM] Starting server with configuration: {"hostname":"127.0.0.1","mnemonic":"candy maple cake sugar pudding cream honey rich smooth crumble sweet treat","network_id":999999,"port":8545,"total_accounts":10,"unlocked_accounts":[]}

This kind of implies it's trying to spin up a ganache-cli server internally, instead of connecting to one with that networkid/port

ever got this to work? @nickysemenza

[nickysemenza]

Nope 😕

If you have the GUI running on 8545, you don't need to run ganache-cli again. If the container can read that port you should be able to access it via RPC.

[siman]

@kowsheek the idea behind having CLI and GUI is to run CLI on Ubuntu server, and connect GUI on my laptop and see what is going on in server's blockchain. I cannot run GUI on Ubuntu server.

Any updates on this?

[mikeseese]

Hey everyone! As you have found out, Ganache currently cannot connect to another RPC endpoint such as ganache-cli.

With that said, unfortunately we don't have an update on if/when this will be implemented.

It's definitely on our radar, but not on deck to implement.

@seesemichaelj or anyone else: is there any way to start the Ganache UI electron app with high ether values for all its accounts instead of just 100. I need it to perform some tests that involve high ether values. Like this script from Open Zeppelin: https://github.com/OpenZeppelin/openzeppelin-solidity/blob/master/scripts/test.sh . I 'am using it to successfully do my test with ganache-cli but UI app would be better for demo purposes. Thx.

[mikeseese]

@lakamsani in the next release in the coming weeks, there will be some additional settings you can change to do this.

In the meantime you can modify your settings file:

• MacOS: ~/Library/Application\ Support/Ganache/Settings
• Windows: %APPDATA%\Ganache\Settings.
• Linux: either $XDG_CONFIG_HOME/Ganache/Settings or ~/.config/Ganache/Settings.

The "server" object actually gets passed as is to ganache-cli/core. So you can just add the default_balance_ether attribute here (see https://github.com/trufflesuite/ganache-core/blob/develop/README.md#usage)

[lakamsani]

@seesemichaelj thx for that suggestion. I tried and it doesn't seem to pick up anything from there. Neither the mnemonic nor the default_balance_ether. I 'm running via npm start from the cloned repo. Would it look elsewhere in this case?

[lakamsani]

I was actually able to save those values from the GUI preferences! Should have looked there first. 👍

[mikeseese]

@lakamsani Ah, yes the Settings file is actually at .../Electron/Settings instead of .../Ganache/Settings when you run npm start

You are correct; they are in the GUI in the develop branch. It should go without saying, but working out of the develop branch can come with bugs as you're running with the latest stuff.

[mikeseese]

If someone was interested in tackling this issue (I saw @oxidizer was potentially interested [or I have the wrong GitHub username]), some points of interest for you to see the interactions between the GUI and ganache-core to try to abstract it to point to a CLI instance rather than starting one up:

• you would likely want to take at src/common/services/ChainService.js - this file is where the main electron process communicates with the "chain process" by starting node and pointing it at a script (src/chain/chain.js) which kicks off ganache core. you would want to abstract this service to either start ganache core or point to another
• https://github.com/trufflesuite/ganache/blob/fbe50d94fb7f7c07a436280e6ec87745ea2a0a56/src/main/main.js#L133 here is where the ChainService is created in the main process. look for where chain is used in that file to make sure you support all of the usages

This may have once been somewhat trivial, but after we did the work for workspaces (which are not supported in ganache-core/cli) there are some nuances that may not be so easy to port the functionality

[vforvalerio87]

Any updates on this?

As an alternative, since the GUI still uses the same ganache-core/cli, can you use Ganache GUI to do the fork directly instead of using the cli?

If none of the above are possible today, is there a way we could fund the development of this feature so it moves higher up the list? Feel free to reach out directly if you want to discuss this further at valerio at ocelot dot net

Thanks

[mikeseese]

@davidmurdoch has really become the owner around Ganache and would be able to provide a better response, so I'll defer to him on this one

[dportabella]

I also have ganachi-cli running on a development server.
is there any web application (simulating ganachi-gui) that I could install on the server, that connects to ganachi-cli?

[SalahAdDin]

@dportabella Did you find something?

[diogomartino]

@SalahAdDin I'm also interested. Did you find anything?

[SalahAdDin]

@Bruxo00 Unfortunately.

[dportabella]

@Bruxo00, I gave up on ganache temporally. I am currently using the free version of the infura.io service.

[jknight]

Maybe I'm missing something, but this would seem like a great feature on an already amazing UI : it can spin up its own blockchain, the way it does today, or connect to an existing running instance and just be a UI

[adamwojt]

I second that. I tried today and Ganache GUI wants to spawn another chain. Would be good to have that supported. On top of above described use-case with Ubuntu server there is one more. For brownie users when using development console, ganache-cli is automatically spawned. All I need in this case is block explorer.

[Plumillon]

Need to have that supported, I'm running ganache-cli on a Docker container and would love to explore it via Ganache UI

[samholmes]

Updates on this? I prefer ganache-cli to start the RPC service over the UI. This way the UI is optional for development and is only used when needed to explore the local blockchain created by ganache-cli.

[davidmurdoch]

I started work on this here: #5633

Anyone savvy enough with JSON-RPC, web3.js, and React want to give it a shot at optimizing this to handle mainnet in a way that doesn't crawl to a hault when viewing the transactions tab? Bonus points if you get Truffle Project and Events working!
