Truffle & Kaleido Truffle Box

This box gives you a boilerplate to get up and running quickly with Truffle on a Kaleido chain.

Installation

First ensure you are in a new and empty directory. Choose one of the following options to download and install the Kaleido Truffle box

In your preferred directory run the unbox command with npx. This will install all necessary dependencies.

npx truffle unbox kaleido-io/truffle-kaleido-box

Alternatively, install Truffle globally and then run the unbox command in your preferred directory.

npm install -g truffle
truffle unbox kaleido-io/truffle-kaleido-box

Connect to Kaleido

In the Kaleido console, navigate to your environment, click on Security in the left hand navigation menu, then click on App Creds
Click New App Cred and give it a name and click Create. Do not close this window until we have completed the steps below
Navigate to where you downloaded the Kaleido Truffle Box in the section above. Open up the truffle-config.js file in your preferred IDE
Back in the Kaleido console, copy the JSON/RPC HTTP endpoint with valid App Creds that's generated in the right hand menu.
Paste this full URL into Line 9 where you see 'nodeConnectionURL'. Make sure to keep the URL that you insert inside quotation marks
If you are using Quorum in this environment, ensure to uncomment the type: "quorum" property on your network object.

Running Truffle

Run the development console. This will instantiate a local chain for you to test that Truffle is working properly.

truffle develop

Ensure that you're able to both compile, test, and finally migrate your contracts to your local chain.

compile
test
migrate

If everything looks good, you can exit the Truffle console with .exit.

truffle-kaleido-box's Issues

`out of gas` on migration

newer solidity versions have out of gas issues deploying our sample contracts.

Specify the solidity version in the truffle-config.js

  compilers: {
    solc: {
      version: "0.5.0",
    },
  }

from @cruz:

@adam.chasen I believe in one of the more recent versions of truffle, we bumped the solidity version to 0.5.8 (which defaults the evmVersion to petersburg and would probably be the cause of outputing diff bytecode) (edited)

Note: truffle version is deprecated and no longer returns correct version information for solidity. Need to look at compile output to see which solidity truffle uses.

npm package install/remove errors on websocket directory

Not sure if this is part of our configuration or something universal to truffle (boxes):

npm ERR! path /home/achasen/tmp/truf/node_modules/websocket
npm ERR! code EISGIT
npm ERR! git /home/achasen/tmp/truf/node_modules/websocket: Appears to be a git repo or submodule.
npm ERR! git     /home/achasen/tmp/truf/node_modules/websocket
npm ERR! git Refusing to remove it. Update manually,
npm ERR! git or move it out of the way first.

Workaround: remove the directory
