I have a few questions regarding setting up a TTN backend network server development environment as follows:
. Instruction for setting up the development environment
There are two source code trees as below:
(1) v1-staging : https://github.com/TheThingsNetwork/ttn/tree/v1-staging
(2) v2-preview : https://github.com/TheThingsNetwork/ttn/tree/v2-preview
I guess v1-staging is what we are currently using and v2-preview is the production version that’s planned to be released in December this year. Am I right?
I guess v2-preview is currently under development and the code will be changing every day, and there is no code change for v1-staging.
Due to this reason, I’d like to set up the development environment and compile v1-staging first before I try to compile v2-preview.
I see there is an instruction for setting up for v2-preview but there is no set up instruction for v1-staging. Does the instruction for v2-preview apply to v1-staging?
 Which OS and version?
Which Linux version is preferred for the development environment? Is Ubuntu preferred? If it is, is the latest version of Ubuntu ok?
 Go lang and other component versions
I need to download and set up these components - Go, protobuf compiler, Redis, RabbitMQ - according to the instruction. I assume I should download the latest version of these components. Am I right?
 To run TTN network server locally
According to the instruction, I am supposed to run ‘forego start’ to start all backend services at the same time.
Can I start each TTN server component separately such as ‘ttn router’, ‘ttn broker’, ‘ttn networkserver’, ‘ttn handler’?
 Configuration file for each TTN server component?
If I ran TTN router, broker, handler, and network server separately on different hardware (with different IP addresses), I should configure these components with correct IP addresses so they can talk to right counterparts. Is there a configuration file for each TTN server component?
