Re: How to get inside docker container and debug code with breakpoints?
David Enyeart
Close... some key within the [Group] config has an illegal character. You can see the valid characters here: I might also add that in this case, the error message and backtrace are actually extremely informative "Illegal characters in key: [Group]" I'm guessing it doesn't like the brackets in "[Group]" "/opt/gopath/src/github.com/hyperledger/fabric/orderer/common/server/main.go:98" Tells you exactly where the "Failed validating bootstrap block" problem is. A debugger would absolutely not tell you much more. On 10/24/2019 5:29 PM, Siddharth Jain wrote:

So I am wondering if there is a way for me to log into the container and be able to debug with a debugger (like the way we could do using gdb or ddd)? Would appreciate step by step instructions please which can be followed by a poor man like me (not hand wavy answers)
