Postgres semble fonctionner correctement lorsqu'un conteneur est démarré en utilisant la même image avec Docker Run

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

J'ai essayé votre docker-compose et le service semble fonctionner dans le conteneur:

root@0afe99de0f0b:/# ps aux

Quoi qu'il en soit, pour mon projet, j'utilise une autre image pour postgresql: https://github.com/sameersbn/docker-postgresql . Celui-ci fonctionne bien.

Si vous regardez la sortie de votre journal, les lignes suivantes apparaissent vers la fin:

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

Apparemment, l'arrêt et le redémarrage du serveur Postgres font partie du processus d'initialisation. En fait, l'avant-dernière ligne dit

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