error at docker

[KaungZawHtet]

When I run in ./my-project-exe at /service/build on docker, the err is shown :

 E |2020-10-11 19:00:01 1602442801238882| [oatpp::network::tcp::server::ConnectionProvider::instantiateServer()]:Error. Couldn't bind. Address not available
terminate called after throwing an instance of 'std::runtime_error'
  what():  [oatpp::network::tcp::server::ConnectionProvider::instantiateServer()]: Error. Couldn't bind Address not available
Aborted

Is there something I missed ?

Hey @KaungZawHtet ,

I've changed connection provider settings to:

return oatpp::network::tcp::server::ConnectionProvider::createShared({"0.0.0.0", 8000, oatpp::network::Address::IP_4});

Now it should work.

You can also play with host, and IP version.

Please let me know if it works for you now.

Regards, Leonid

Same problem:

E |2020-10-11 21:33:13 1602451993394144| [oatpp::network::tcp::server::ConnectionProvider::instantiateServer()]:Error. Couldn't bind. Address in use

Hey @KaungZawHtet ,

Not the same:

In the first case, you had

Error. Couldn't bind Address not available - # like for example if you were trying to use IPv6 addr which was not available.

And in the second case:

Error. Couldn't bind Address in use - # Mean that you already have some service running on that address.

So, you have to check if something already running on the address. Or change the host/port.
