Postgres tắt ngay lập tức khi bắt đầu với docker-compose

Question

Postgres tắt ngay lập tức khi bắt đầu với trình tạo docker. Các tập tin yaml sử dụng dưới

version: '2' 

services: 
    postgres: 
     image: postgres:9.5 
     container_name: local-postgres9.5 
     ports: 
      - "5432:5432" 

Nhật ký khi Docker-soạn lên lệnh được thực thi

Postgres dường như làm việc tốt khi một container được bắt đầu sử dụng cùng một hình ảnh với Docker chạy

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

Answer 1

Tôi đã cố gắng tạo docker và dịch vụ có vẻ như đang chạy trong vùng chứa:

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 
postgres 74 0.0 0.0 227148 1768 ?  Ss 14:42 0:00 postgres: checkpointer process 
postgres 75 0.0 0.0 227148 1772 ?  Ss 14:42 0:00 postgres: writer process 
postgres 76 0.0 0.0 227148 1768 ?  Ss 14:42 0:00 postgres: wal writer process 
postgres 77 0.0 0.1 227576 2720 ?  Ss 14:42 0:00 postgres: autovacuum launcher process 
postgres 78 0.0 0.0 82132 1888 ?  Ss 14:42 0:00 postgres: stats collector process 
root  79 2.0 0.0 21820 1984 ?  Ss 14:42 0:00 /bin/bash 
root  84 0.0 0.0 19092 1296 ?  R+ 14:42 0:00 ps aux 

Dù sao, đối với dự án của tôi, tôi sử dụng một hình ảnh khác cho postgresql: https://github.com/sameersbn/docker-postgresql. Điều này hoạt động tốt.

Answer 2

Nếu bạn nhìn vào dữ liệu ghi nhận của bạn, những dòng sau xuất hiện phía cuối:

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

Rõ ràng, dừng lại và khởi động lại máy chủ Postgres là một phần của quá trình khởi động. Trên thực tế, dòng thứ hai đến cuối cùng cho biết

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