where to view the chaincode log

[yqbjtu]

I write some chaincode and deploy it . but there is some results, which is not my expected. I add some log to chiancode as debug info like "fmt.Println("id:" + args[0] + " - state" + args[1])", after I enter into the docker by "docker exec -it xxxx bash", then can't find where the chaincode log is.

Thank you!

see through the docker-compose start cli.
or use docker-compose logs -f where the docker-compose.yml stays.

Thank you very much! "docker-compose logs" does show the log

I use
var logger = shim.NewLogger("BienChaincode")
func main() {
logger.SetLevel(shim.LogInfo)
err := shim.Start(new(BienChaincode))
if err != nil {
fmt.Printf("Error starting BienChaincode chaincode: %s", err)
}
}

then call logger.Infof("init logger arg0=%s", args[0])

when I used the
peer chaincode deploy -p ./ -c '{"Function":"init", "Args": ["hi there2"]}' -u jim

to deploy the chaincode, in the container interal, it seem that "docker-compose logs" can't show the log.

yes, in that case, you should find your chaincode container id by docker ps, then use

docker logs -f chaincode_container_id
