Very often I keep into running cryptic errors with Fabric. E.g.,
today I ran into this:
2019-10-25 00:20:00.915 UTC [orderer.common.server] Start
-> PANI 003 Failed validating bootstrap block: initializing
configtx manager failed: error converting config to map:

panic: Failed validating bootstrap block: initializing

With these kinds of errors, its not possible to know what caused
it just by looking at trace above and I am helpless what to do
next. 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)
