Postgres निष्पादित ठीक से काम करने लगता है है जब एक कंटेनर डोकर रन के साथ ही छवि का उपयोग शुरू कर दिया है

docker run --name local-postgres9.5 -p 5432:5432 postgres:9.5 

Answer 1

मैंने आपके डॉकर-कंपोज़ की कोशिश की और सेवा कंटेनर में चल रही है:

root@0afe99de0f0b:/# ps aux 
USER  PID %CPU %MEM VSZ RSS TTY  STAT START TIME COMMAND 
postgres  1 0.5 0.8 227148 16128 ?  Ss 14:42 0:00 postgres

root  84 0.0 0.0 19092 1296 ?  R+ 14:42 0:00 ps aux 

वैसे भी, मेरी परियोजना के लिए मैं postgresql: https://github.com/sameersbn/docker-postgresql के लिए एक और छवि का उपयोग करता हूं। यह ठीक काम करता है।

Answer 2

आप अपने लॉग उत्पादन को देखें, तो निम्नलिखित लाइनों अंत में प्रकट:

local-postgres9.5 | server stopped 
local-postgres9.5 | 
local-postgres9.5 | PostgreSQL init process complete; ready for start up. 

जाहिर है, को रोकने और पुन: प्रारंभ Postgres सर्वर initialisation प्रक्रिया का हिस्सा है। वास्तव में, दूसरी-से-आखिरी पंक्ति कहती है

local-postgres9.5 | LOG: database system is ready to accept connections.
