I am trying to run a sample chaincode application on hyperledger fabric by following the steps mentioned in their github url
I am able to start the network using docker compose, below are the running containers:

Now when I try to build the sample abstore Go application from within the chaincode container, I get the below error everytime.
/opt/gopath/src/chaincode/abstore/go $ go build -o abstore go build
github.com/hyperledger/fabric-samples/chaincode/abstore/go: open
abstore: permission denied.
Can someone guide me here where I am going wrong.
The issue was resolved after giving complete access to the folders using :
sudo chmod -R 777 .

I am using Hyperledger Composer version v0.19.9 and Hyperledger Fabric version v1.1.
I have setup my blockchain network using Fabric and made all docker containers up and running. Following docker containers are running:
1. cli
2. orderer.sterlite.com
3. peer0.orga.sterlite.com
4. ca.orga.sterlite.com
5. peer0.orgb.sterlite.com
I have created a Peer Admin card using Composer CLI named PeerAdminOrgA#sterlite.
Now, when I try to install a business network using below command, I am getting an error:
composer network install -c PeerAdminOrgA#sterlite -a com-fab-bn.bna
Following is the error:
safvan#safvan-VirtualBox:~/blockchain/fabric-sdk/fabric-sdk-go/src/github.com/sterliteChain/config$ composer network install -c PeerAdminOrgA#sterlite -a com-fab-bn.bna
Installing business network. This may take a minute...
Error: Error trying install business network. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: 14 UNAVAILABLE: EOF

I am trying to deploy BNA to Fabric but getting this error

I installed Fabric using step 4 of this guide then ran
./startFabric.sh
./createPeerAdminCard.sh
prior to deploying BNA.
EDIT:
$ docker -v
Docker version 18.02.0-ce, build fc4de44
$ system_profiler SPSoftwareDataType

I concluded that my issue was because of me using docker-machine to run Docker instead of running Docker via daemon.
I solved it by adding the ports used to VirtualBox.
I am following the link: https://hyperledger.github.io/composer/tutorials/deploy-to-fabric-multi-org to deploy bna file in 2 different peers.
Up to step-16 everything is working fine, but when I am trying to deploy the .bna file getting following error.
After importing the identity cards to composer when I have run "install runtime" command for Org1, it is successfully processed but when I am running for Org2 it is showing "No valid responses from any peers" error.
Following are the output.

Please help how to resolve this. Thanks
I did the following modification in "peer-base.yaml" file and issue has been resolved.
- CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=${COMPOSE_PROJECT_NAME}_byfn
To
- CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=network_amsnetwork
Here "network_amsnetwork" is the network name. You can find your network name by using "docker network ls" command
when I run
composer network start -c PeerAdmin#hlfv1 -a test-network.bna -A admin -S adminpw
it took a long time then got a timeout error
Error: Error trying to instantiate composer runtime. Error: No valid responses from any peers.

The composer network start command is creating a new docker container and using npm install within that container, so your timeout could be a result of a slow system creating the container, and/or slow performance of the npm install command.
The default timeout is 300 seconds, but you can increase that value with the environment variable CORE_CHAINCODE_EXECUTETIMEOUT=800s
If you look at the docker-compose yaml file that is used to start your Fabric (specifically the Peer) then you can add an additional line for this environment variable.
If you are using the default Dev Fabric, the file you are looking for is probably: ~/fabric-tools/fabric-scripts/hlfv11/composer/docker-compose.yml
I am trying to pass in the channel configuration transaction artifact to the order-er using the command:
peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls --cafile
/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
But I get an error:
2018-03-17 20:55:21.380 GMT [main] main -> ERRO 001 Fatal error
when initializing core config : error when reading core
config file: Unsupported Config Type ""
What does this error mean? and how can I fix it?
Using docker ps -a

this is the log of orderer.example.com
You should be inside the CLI container to execute the peer channel create command.
You will enter the CLI container using the docker exec command:
docker exec -it cli bash
If successful you should see the following:
root#0d78bb69300d:/opt/gopath/src/github.com/hyperledger/fabric/peer#
Over there, you should run the peer channel create command like this:
root#0d78bb69300d:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
Before running this command, please note that you should also run commands for creating environment variables for CHANNEL_NAME and other Environment variables for PEER0 within this CLI Container.
export FABRIC_CFG_PATH=$PWD. it will resolve this issue.
This is the error you get when the core.yaml is not found. Like the Mukesh mentioned above, running command within the CLI Container will not throw the Error.
See this link for more detail.
Can you try running this command: echo $FABRIC_CFG_PATH
Whatever value you get, can you navigate to that directory and confirm if you can see the configtx.yaml file in there.
From the docs here, it says the error is as a result of inappropriately setting the value of that variable.
