Hi Bozhidar,
Can you share the commands/output from when you packaged the chaincode? You may also find it helpful if you have not already done so, to review the tutorial “Deploying a Smart Contract to a Channel” in the fabric docs to confirm you completed the necessary steps in order. 

Chris

In the log of the peer - nothing interesting.


Hope someone face the same or will help solving with the issue!

Thanks in advance,

Re: Search for an endorsement policy translator for Node.js SDK v1.4

Mr.Phuwanai Thummavet
 

Thank you for your response. 

But I'm not sure if your script generates the correct format for sendInstantiateProposal()​ or sendUpgradeProposal()​?

As the output is different from the JSON object according to this reference: https://hyperledger.github.io/fabric-sdk-node/release-1.4/global.html#ChaincodeInstantiateUpgradeRequest

Please pardon me for my innocent.

Subject: [EXTERNAL] [Hyperledger Fabric] Search for an endorsement policy translator for Node.js SDK v1.4
Date: Thu, Aug 27, 2020 11:36 AM
 
Hi Everyone,

I'm using Node.js Fabric SDK v1.4 for managing chaincode operations such as installing, instantiating, and upgrading. When to instantiate or upgrade a chaincode, I have to provide an endorsement policy in terms of a JSON object like the following.
{
  identities: [
    { role: { name: "member", mspId: "org1" }},
    { role: { name: "member", mspId: "org2" }}
  ],
  policy: {
    "1-of": [{ "signed-by": 0 }, { "signed-by": 1 }]
  }
}
 
That works but makes a bit of pain to me. Does anyone have any solution to translate the endorsement policy like this "OR('org1.member', 'org2.member')", for example, to the above JSON object?

Thank you so much.

traffic can go out out does not mean that traffic can come in, so ping google does not really mean your necessary ports are open.
as I have indicated earlier in this doc, https://github.com/litong01/minifabric/blob/master/docs/RunningOnFedora.md, you can do first 2 steps to open up ports to solve firewall related issues.

Sent by: fabric@...



      Looks like that the user can not access docker endpoint and also cannot even create a file when the current directory is mounted to the container, you need to fix these permission errors first.
I already assumed something like this, so I started it as root. It's weirdly causing very similar issues. In my opinion it's more a Fedora/Docker issue and not so much related to permissions. I have encountered other strange behaviours when you try to mount something into a Docker under Fedora. See the appendix to this reply. I'm getting different errors when I remove all Hyperledger-Images and try to start the test-network.
      I suspect the problem might be the same cause your other attempt also had errors. I would manually mount a directory to a container and exec into it and see why there were permission errors. If you give me a bit more details about your system such as OS version, how your docker was installed and its version, and what user you are using, I probably can dig it bit further.
This is a Fedora VM (30). The Docker is installed according to the very basic tutorial: https://docs.docker.com/engine/install/fedora/
Firewall-related I'm not very skilled, so I tried to allow as much as possible. No change. Also, as alpine can ping Google I'm in the opinion it's not a firewall-issue

Looks like that the user can not access docker endpoint and also cannot even create a file when the current directory is mounted to the container, you need to fix these permission errors first.
I already assumed something like this, so I started it as root. It's weirdly causing very similar issues. In my opinion it's more a Fedora/Docker issue and not so much related to permissions. I have encountered other strange behaviours when you try to mount something into a Docker under Fedora. See the appendix to this reply. I'm getting different errors when I remove all Hyperledger-Images and try to start the test-network.
I suspect the problem might be the same cause your other attempt also had errors. I would manually mount a directory to a container and exec into it and see why there were permission errors. If you give me a bit more details about your system such as OS version, how your docker was installed and its version, and what user you are using, I probably can dig it bit further.
This is a Fedora VM (30). The Docker is installed according to the very basic tutorial: https://docs.docker.com/engine/install/fedora/
Firewall-related I'm not very skilled, so I tried to allow as much as possible. No change. Also, as alpine can ping Google I'm in the opinion it's not a firewall-issue

Hi Bozhidar,
Can you share the commands/output from when you packaged the chaincode? You may also find it helpful if you have not already done so, to review the tutorial “Deploying a Smart Contract to a Channel” in the fabric docs to confirm you completed the necessary steps in order. 

Chris

Unable to fetch private data from peers (Empty membership) and can't commit new transactions - Hyperledged Fabric 1.4.6

mvtavares@...
 

Hello everyone. I got a problem with an 1.4.6 Fabric network with a network (27 peers and 5 orderers) where there is one peer (anchor peer) in an Organization that stopped commiting transactions. I can't understand why it started showing this message without any updates on the network, but it was working normally before that.

The message is:

2020-08-26 19:56:35.147 UTC [gossip.privdata] fetchPrivateData -> WARN fc2 Do not know any peer in the channel( xxxx ) that matches the policies , aborting
2020-08-26 19:56:35.147 UTC [gossip.privdata] fetchFromPeers -> WARN fc3 Failed fetching private data for block 743444 from peers: Empty membership
2020-08-26 19:56:36.149 UTC [gossip.privdata] fetchPrivateData -> WARN fc4 Do not know any peer in the channel( xxxx ) that matches the policies , aborting

I know we should have other peers configured to disseminate the pvt data, but unfortunately we didn't did it and now i need to find a way to make this peer work again. All the others 26 are fine and they all have the same config (changing only the Organization). Can anyone help me to find a way to just make this peer accept and commit new transaction even if it causes some of the pvt data to be lost ?

We've already tried to update the chaincode of this specific channel and while all the 26 peers confirmed the upgrade and are OK, this specific one still returns with the older version when we issue "peer chaincode list --instantiated channel".

Any help would be greatly appreciated.

Hello All,

The peer has joined the channel and chaincode is packed on.

I have a problem with instantiating chaincode in Hyperledger fabric Network version 2:
# peer lifecycle chaincode install chaincode.tar.gz

It gives me:

Subject: [EXTERNAL] [Hyperledger Fabric] Search for an endorsement policy translator for Node.js SDK v1.4
Date: Thu, Aug 27, 2020 11:36 AM
 
Hi Everyone,

I'm using Node.js Fabric SDK v1.4 for managing chaincode operations such as installing, instantiating, and upgrading. When to instantiate or upgrade a chaincode, I have to provide an endorsement policy in terms of a JSON object like the following.
{
  identities: [
    { role: { name: "member", mspId: "org1" }},
    { role: { name: "member", mspId: "org2" }}
  ],
  policy: {
    "1-of": [{ "signed-by": 0 }, { "signed-by": 1 }]
  }
}
 
That works but makes a bit of pain to me. Does anyone have any solution to translate the endorsement policy like this "OR('org1.member', 'org2.member')", for example, to the above JSON object?

Thank you so much.

Try minifabric, only takes 5 minutes to know if it works for you or not.

Re: Issues with docker in Fedora 30? #docker

I thought so too at first as I'm aware Fedora has a more restrictive security guideline. I installed firewalld and did according to the provided manual. It's different now, but still nothing works:

Hi Nathan,

 

This is definitely possible. Chainstack customers are running production-grade Hyperledger Fabric 2.x networks in exactly three clouds you mentioned.

Subject: [Hyperledger Fabric] Hyperledger Fabric Multi Cloud Setup (Azure, AWS and GCP), Multi Version Setup and Integration -- Hyperledger Fabric 1.2 (AWS Managed), Hyperledger Fabric (HLF) on Azure Kubernetes Service (AKS)

 

Hi everyone,

 

I have an existing Hyperledger Fabric 1.2 (AWS Managed Blockchain) and Hyperledger Fabric (HLF) on Azure Kubernetes Service (AKS) 

 

As part of anti-fragile designand architect, there is a need to extend and/or create a fabric network that spans across multiple cloud providers (Azure, AWS, GCP).

 

Key idea here is to have multiple ordering services and all the peer nodes distributed across the 3 major cloud providers to achieve true resilience/decentralization. This is to ensure that the platform on which hyperledger fabric is deployed is sufficiently decentralized, too. 

 

Is this within the realm of possibility from the design of hyperledger fabric?

 

Thank you.

 

Regards,

 

Nathan Aw

Hi Nathan,

As Jacov suggests you have to upgrade your network (ordering service, peers, etc) to 1.4.x (and then optionally to 2.x) in order to get the RAFT based HLF Ordering Service that can be managed by multiple service providers (OSPs) and orderers can be added on the fly.

To understand more about 1.4.x you can read through https://hyperledger-fabric.readthedocs.io/en/release-1.4/whatsnew.html. You can find there a migration guide and all the information you need to distribute your peers/orderers and Service Providers.

It will take some reading and time to implement it. That is very essential topic though as cross cloud deployments are quite important considering the nature and meaning of DLT paradigm.  My team had to go through and automate all these steps while building the channel management feature of consortia.io (essentially HLF channel update transaction managed by chaincode deployed on HLF network). Honestly this is not a simple process and requires time to understand and implement. Don't hesitate to ask ... I can help in pointing to the right information.

Regards,
Tsvetan
