Installing the same chaincode on two channels

[rrozek]

Hi, tremendous progress in fablo 1.1.0! However i noticed, that I cannot install the same chaincode on two separate channels. My config is for 2 orgs, 2 peer per org, 1 channel per org and i want to install the same chaincode on both channels. It fails on:

}

i can workaround it by setting different name but the same source directory, however it would be convinient if it could go under the same name.

  "chaincodes": [
    {
      "name": "chaincode-test-channel1-org1",
      "version": "1.0.0",
      "lang": "node",
      "channel": "channel1-org1",
      "directory": "./chaincodes/chaincode-test"
    },
    {
      "name": "chaincode-test-channel1-org2",
      "version": "1.0.0",
      "lang": "node",
      "channel": "channel1-org2",
      "directory": "./chaincodes/chaincode-test"
    }
  ]

Hey @rrozek thanks for kind words :)
About the issue - yes, it's a known problem reported here.
We'll try to fix it soon, so I'm leaving the issue opened and will let you know when it happens :)

[rrozek]

huh. was looking in open issues and didn't find it -_-' sorry for duplicate!

[dzikowski]

probably a solution for this issue is to use in Fablo docker mounts for directories like channel-name/chaincode-name instead of just chaincode-name. It will allow to avoid duplicate mounts error
