I am trying to deploy Hyperledger fabric 1.0.5 on k8s, and use the balance transfer to test it. Everything is right before instantiate-chaincode, and I get this:
[2019-01-02 23:23:14.392] [ERROR] instantiate-chaincode - Failed to send instantiate transaction and get notifications within the timeout period. undefined
[2019-01-02 23:23:14.393] [ERROR] instantiate-chaincode - Failed to order the transaction. Error code: undefinedand I use kubectl logs to get the peer0's log which is like this:
[ConnProducer] NewConnection -> ERRO 61a Failed connecting to orderer2.orderer1:7050 , error: context deadline exceeded
[ConnProducer] NewConnection -> ERRO 61b Failed connecting to orderer1.orderer1:7050 , error: context deadline exceeded
[ConnProducer] NewConnection -> ERRO 61c Failed connecting to orderer0.orderer1:7050 , error: context deadline exceeded
[deliveryClient] connect -> DEBU 61d Connected to
[deliveryClient] connect -> ERRO 61e Failed obtaining connection: Could not connect to any of the endpoints: [orderer2.orderer1:7050 orderer1.orderer1:7050 orderer0.orderer1:7050]I checked the connectivity of orderer0:7050 and found no problem.
What should I do next？
Thank for help！
It looks like firewall problem.
In my case to run hlf on k8s, I disabled firewall service.
You didn't describe what runbook you followed to deploy Hyperledger Fabric but looks like your pods cannot find each other through DNS. If you are following Kubernetes standards your pods should be in the orderer1 namespace and hopefully, you have Kubernetes services for orderer0, orderer1, and orderer2.
You can read more about communication between the Fabric components here in the "Communication between Fabric components" section. Also, read on the "Work around the chaincode sandbox" where it shows you a workaround for --dns-search.
