Deployed application API is accessible by URL: http://127.0.0.1:8080/api/v1/ltp

Possible compile errors

Windows 10

failed to run custom build command for openssl-sys v0.9.102

The possible solution to build 'openssl' library is available by a link

Other possible errors

If you see below error in running docker container

ERROR crypto_ltp_example::routes::last_trade_price] Not fetched pair = "BTC/USD" due to error: Connect is failed: error sending request for url (https://api.kraken.com/0/public/Ticker?pair=BTCUSD)

There are number of reasons possible that prevent internal container code to access external internet (firewall, network settings). There is no one solution for all OS and situations, sorry.
