为多机执行对等链代码查询时，无法获取 mycc:1.0 的链代码容器信息
failed to get chaincode container info for mycc:1.0 while executing peer chaincode query for multi machine
我正在尝试在 2 台不同的物理机器上设置具有 2 个组织的超级账本网络 运行ning。所以机器 1 有 orderer、peer0.org1、peer1.org1、ca-org1、couchdb1、couchdb2 和 cli 容器。机器 2 有 peer0.org2、peer1.org2、ca-org2、couchdb3、couchdb4 和 cli 容器。

如您所见，我正在使用 "extra_hosts" 连接到其他机器中的 docker 容器。
这样我就可以从一台机器创建频道并从该机器为两个对等方加入频道。在另一台机器上，我获取了相同的频道配置并为两个对等点加入了相同的频道。
我通过以下命令检查了两台机器中的所有 4 个对等点是否都加入了同一个频道 -
peer channel list
peer channel getinfo -c mychannel
现在我已经从机器 1 安装并实例化了链代码。这工作正常。使用以下命令安装和实例化 -
peer chaincode install -n mycc -v 1.0 -l golang -p github.com/chaincode/chaincode_example02/go/
peer chaincode instantiate -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc -l golang -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')"
如果我从同一台机器查询链代码，它工作正常，我得到了正确的结果。
peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
但是当我从不同的机器执行相同的链代码查询命令时，它给出了以下错误 -
Error: endorsement failure during query. response: status:500 message:"failed to execute transaction 2444b829db1485ad097b2e11442d65cb36f02de1c6a3f3372ad53594af4d1a4d: [channel mychannel] failed to get chaincode container info for mycc:1.0: could not get chaincode code: chaincode fingerprint mismatch: data mismatch"
我可以看到 hyperledger fabric 正在两台机器上正确同步所有对等点。因为当我 运行 peer channel getinfo -c mychannel 我可以匹配所有 4 个对等点的 currentBlockHash、previousBlockHash 和高度值。我只是无法从另一台机器执行 peer chaincode query 命令。
当我使用 运行 peer chaincode instantiate 命令时，我可以看到在机器 1 中创建了一个新的 docker 容器，用于 运行ning 链代码。但是机器2中没有这样的容器。
我是否缺少此处的任何配置，以便可以从机器 2 访问在机器 1 上创建的链代码容器？
新发现：
我已经通过 CLI 容器中的 运行ning peer chaincode install 命令在两台机器的所有 4 个对等节点上安装了链码。我在两台机器上有两个 CLI 容器 运行ning。
当我运行命令peer chaincode list --installed。在机器 1 中，我得到如下结果
Name: mycc, Version: 1.0, Path: github.com/chaincode/chaincode_example02/go/, Id: 333a19b11063d0ade7be691f9f22c04ad369baba15660f7ae9511fd1a6488209
当我在机器2中运行同样的命令时，除了Id的值不同，结果是一样的。但我还发现 Id 值对于同一台机器上的两个对等点是相同的。可能这就是为什么我能够在同一台机器上执行来自两个对等方的链码查询的原因。但无法从其他机器 运行 它。看起来这是这个问题的根本原因。
您是否也在您的其他节点上安装了 ChainCode？
When I run peer chaincode instantiate command I can see a new docker container is created in machine 1 which is for running chaincode. But there is no such container in machine 2. Am I missing any configuration here so that the chaincode container created on machine 1 can be accessed from machine 2?
这是预期的。取自文档：“链码容器在针对该链码执行初始化或传统交易之前不会为对等方启动”
因此，只需识别为您的另一个对等方，按照与第一个对等方相同的方式安装链码，然后您可以与该对等方进行调用（查询或调用无关紧要），您会看到链码容器会上来的。
我最终能够找出问题所在，所以在这里发布了一个答案。问题是当我从两台不同的机器安装链码时，链码 Id 是不同的。之前我使用命令 peer chaincode install -n mycc -v 1.0 -l golang -p github.com/chaincode/chaincode_example02/go/ 在两台机器上分别安装链代码。因此，当我执行 peer chaincode list --installed 时，它显示 Id 值不同。
我能够使用稍微不同的方法来解决它。首先使用命令 peer chaincode package ccpack.out -n mycc -l golang -p github.com/chaincode/chaincode_example02/go/ -v 1.0 创建链代码包。它将生成一个文件 ccpack.out。将此文件从一台机器物理移动到另一台机器。然后使用命令 peer chaincode install ccpack.out 在两台机器上安装相同的包文件。通过这种方式，链码 Id 保持不变并且可以完美运行。
我遇到了同样的错误。对我来说，链码文件是不同的。将整个链代码文件夹复制到同一位置的另一台机器对我有用。
看看这个：
我正在尝试在 2 台不同的物理机器上设置具有 2 个组织的超级账本网络 运行ning。所以机器 1 有 orderer、peer0.org1、peer1.org1、ca-org1、couchdb1、couchdb2 和 cli 容器。机器 2 有 peer0.org2、peer1.org2、ca-org2、couchdb3、couchdb4 和 cli 容器。

如您所见，我正在使用 "extra_hosts" 连接到其他机器中的 docker 容器。 这样我就可以从一台机器创建频道并从该机器为两个对等方加入频道。在另一台机器上，我获取了相同的频道配置并为两个对等点加入了相同的频道。 我通过以下命令检查了两台机器中的所有 4 个对等点是否都加入了同一个频道 -
peer channel list
peer channel getinfo -c mychannel
现在我已经从机器 1 安装并实例化了链代码。这工作正常。使用以下命令安装和实例化 -
peer chaincode install -n mycc -v 1.0 -l golang -p github.com/chaincode/chaincode_example02/go/
peer chaincode instantiate -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc -l golang -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')"
如果我从同一台机器查询链代码，它工作正常，我得到了正确的结果。
peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
但是当我从不同的机器执行相同的链代码查询命令时，它给出了以下错误 -
Error: endorsement failure during query. response: status:500 message:"failed to execute transaction 2444b829db1485ad097b2e11442d65cb36f02de1c6a3f3372ad53594af4d1a4d: [channel mychannel] failed to get chaincode container info for mycc:1.0: could not get chaincode code: chaincode fingerprint mismatch: data mismatch"
我可以看到 hyperledger fabric 正在两台机器上正确同步所有对等点。因为当我 运行 peer channel getinfo -c mychannel 我可以匹配所有 4 个对等点的 currentBlockHash、previousBlockHash 和高度值。我只是无法从另一台机器执行 peer chaincode query 命令。
当我使用 运行 peer chaincode instantiate 命令时，我可以看到在机器 1 中创建了一个新的 docker 容器，用于 运行ning 链代码。但是机器2中没有这样的容器。
我是否缺少此处的任何配置，以便可以从机器 2 访问在机器 1 上创建的链代码容器？
新发现：
我已经通过 CLI 容器中的 运行ning peer chaincode install 命令在两台机器的所有 4 个对等节点上安装了链码。我在两台机器上有两个 CLI 容器 运行ning。
当我运行命令peer chaincode list --installed。在机器 1 中，我得到如下结果
Name: mycc, Version: 1.0, Path: github.com/chaincode/chaincode_example02/go/, Id: 333a19b11063d0ade7be691f9f22c04ad369baba15660f7ae9511fd1a6488209
当我在机器2中运行同样的命令时，除了Id的值不同，结果是一样的。但我还发现 Id 值对于同一台机器上的两个对等点是相同的。可能这就是为什么我能够在同一台机器上执行来自两个对等方的链码查询的原因。但无法从其他机器 运行 它。看起来这是这个问题的根本原因。
您是否也在您的其他节点上安装了 ChainCode？
When I run peer chaincode instantiate command I can see a new docker container is created in machine 1 which is for running chaincode. But there is no such container in machine 2. Am I missing any configuration here so that the chaincode container created on machine 1 can be accessed from machine 2?
这是预期的。取自文档：“链码容器在针对该链码执行初始化或传统交易之前不会为对等方启动”
因此，只需识别为您的另一个对等方，按照与第一个对等方相同的方式安装链码，然后您可以与该对等方进行调用（查询或调用无关紧要），您会看到链码容器会上来的。
我最终能够找出问题所在，所以在这里发布了一个答案。问题是当我从两台不同的机器安装链码时，链码 Id 是不同的。之前我使用命令 peer chaincode install -n mycc -v 1.0 -l golang -p github.com/chaincode/chaincode_example02/go/ 在两台机器上分别安装链代码。因此，当我执行 peer chaincode list --installed 时，它显示 Id 值不同。
我能够使用稍微不同的方法来解决它。首先使用命令 peer chaincode package ccpack.out -n mycc -l golang -p github.com/chaincode/chaincode_example02/go/ -v 1.0 创建链代码包。它将生成一个文件 ccpack.out。将此文件从一台机器物理移动到另一台机器。然后使用命令 peer chaincode install ccpack.out 在两台机器上安装相同的包文件。通过这种方式，链码 Id 保持不变并且可以完美运行。
我遇到了同样的错误。对我来说，链码文件是不同的。将整个链代码文件夹复制到同一位置的另一台机器对我有用。 看看这个：
