docker-composeで起動するとすぐにPostgresがシャットダウンする

Question

Postgresは、docker-composeで起動するとすぐにシャットダウンします。使用YAMLファイルは

version: '2' 

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

コンテナがドッキングウィンドウの実行と同じ画像を使用して開始されたときにドッキングウィンドウ・作曲アップコマンドが

Postgresの実行正常に動作するようですされたログを下回っている

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

Answer 1

私はあなたのドッカーの作成を試みましたが、サービスはコンテナ内で実行されているようです：

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

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

とにかく、私のプロジェクトではpostgresqlの別のイメージを使用します：https://github.com/sameersbn/docker-postgresql。これはうまく動作します。

Answer 2

あなたのログ出力を見れば、次の行は、最後の方に表示されます。

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

はどうやら、Postgresのサーバーを停止し、再起動すると、初期化プロセスの一部です。実際には、2行目から最後の行までは、

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