I am presently working on hyperledger. I have created a 4 organization network and I am trying create a channel from cli container. Below is the command
peer channel create -o orderer.example.com:7050 -c mychannel -f channel.tx
But i am getting an error as mentioned below:
2019-10-18 10:56:58.922 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
Error: rpc error: code = Unavailable desc = transport is closing
please help me solve this problem, Thanks in advance

I have setup for 3 organisations on Kubernetes cluster and it is giving me following error when I restart peer node pod and tried command -> peer channel list on bash shell,

Error: error getting endorser client for channel: endorser client failed to connect to peer0-org1:7051: failed to create new connection: context deadline exceeded
After some time (nearly 10-15 minutes) if I tried same command,

It seems working and give me channel list. I am not able to find out what is reason behind this, Please help for this.
I have been trying to deploy a hyperledger fabric model with 3 CAs 1 orderer and 2 peer nodes. I am able to create the channel with OSADMIN command of fabric but when I try to join the channel with peer node, I get Error: error getting endorser client for channel: endorser client failed to connect to peer-govt:7051: failed to create new connection: context...... .
Here are the logs from terminal (local host machine):

One thing to note down here is I am using Kubernetes and service CLUSTER_IP for all the PODS.
here are logs from one of the PEER POD (same for other)

To overcome this issue, I tried disabling the TLS by setting CORE_PEER_TLS_ENABLED to FALSE
then the proposal gets submitted but the orderer POD throws the same error of TLS handshake failed.........
Here are the commands I am using to join the channel from cli pod:
kubectl -n hyperledger -it exec $CLI_POD -- sh -c "export FABRIC_CFG_PATH=/etc/hyperledger/clipod/config && export CORE_PEER_LOCALMSPID=GeneralMSP && export CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/clipod/organizations/peerOrganizations/general.example.com/peers/peer0.general.example.com/tls/ca.crt && export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/clipod/organizations/peerOrganizations/general.example.com/users/Admin#general.example.com/msp && export CORE_PEER_ADDRESS=peer-general:9051 && peer channel join -b /etc/hyperledger/clipod/channel-artifacts/$CHANNEL_NAME.block -o orderer:7050 --tls --cafile /etc/hyperledger/clipod/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem"
I am stuck on this problem, any help will be appreciated.
Thank you
I have fixed it. The issue I was facing was because of not setting the CORE_PEER_TLS_ENABLED = true for CLI pod.
One thing I have got learn from this whole model, whenever you see TLS issue, first to check for would be checking CORE_PEER_TLS_ENABLED variable. Make sure you have set it for all the pods or containers you are trying to interact with. The case can be false(for no TLS) or true(for using TLS) depending on your deployment.
Other things to keep in mind is using the correct variables of fabric including FABRIC_CFG_PATH, CORE_PEER_LOCALMSPID, CORE_PEER_TLS_ROOTCERT_FILE, CORE_PEER_MSPCONFIGPATH and some others depending on your command.
After starting the image, orderer cannot start normally

I am trying to backup and restore rancher server (single node install), as the described here.
After backup, I tried to turn off the rancher server node, and I run a new rancher container on a new node (in the same network, but another ip address), then I restored using the backup file.
After restoring, I logged in to the rancher UI and it showed the error below:
So, I checked the logs of the rancher server and it showed as below:

After that, I checked logs of the master nodes, I found that the rancher agent still tries to connect to the old rancher server (old ip address), not as the new one, so it makes the cluster not available.
How can I fix this?
You need to re-register the node in Rancher using the following steps.
Update the server-url in Rancher by going to Global -> Settings -> server-url
This should be the full URL with https://
Then use this script to re-register the node in Rancher https://github.com/mattmattox/cluster-agent-tool
Hello Everyone i am working on setup of fabric default first-network in kubernetes. But when i am instantiate the chaincode it gives me error. Please check below are my peer logs.

Once check if all your docker containers are up and running and if you are simply running the sample network without making any changes to the smart contract and the docker files then you can simply stop your network and freshly start the network(it worked in my case).
I have check with my configuration files it was due to wrong CORE_PEER_CHAINCODELISTENADDRESS env variable value for the peer.
