我认为这个问题应该很容易解决,但是我正在拔头发。我有以下docker-compose:
version: "3"
services:
pg-db:
image: postgres:11
environment:
POSTGRES_PASSWORD: "postgres"
POSTGRES_USER: "postgres"
POSTGRES_DB: "postgres"
ports:
- 5432:5432
#network_mode: host
然后我运行docker-compose up
,它将启动容器
pg-db_1_78e7ec4a95e6 | 2020-02-21 13:53:53.928 UTC [1] LOG: database system is ready to accept connections
我可以使用docker exec连接到它
docker exec -it docker_pg-db-compose_1_78e7ec4a95e6 psql -h pg-db -U postgres postgres
但是我无法通过“裸” psql连接到它:
psql postgresql://postgres:postgres@localhost:5432/postgres
psql: could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
psql postgresql://postgres:postgres@pg-dg:5432/postgres
psql: could not translate host name "pg-db" to address: Name or service not known
我尝试过使用network_mode
,但没有帮助。

启动docker-compose之后,您需要执行以下操作获取docker容器ip:
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id
然后您可以进行postgresql://postgres:postgres@<container idp>:5432/postgres
的连接

我正在使用Postgres DockerHub page中提供的docker-compose
文件的修改版本。
version: '3.1'
services:
db:
image: postgres:11
restart: always
ports:
- 5432:5432
environment:
POSTGRES_PASSWORD: postgres
当我运行docker-compose up
时,会收到非常相似的“就绪”消息:
db_1 | 2020-02-21 14:34:17.826 UTC [1] LOG: database system is ready to accept connections
这时,我可以使用psql连接到Postgres。
$ psql -h localhost -U postgres
Password for user postgres:
psql (12.2, server 11.7 (Debian 11.7-1.pgdg90+1))
Type "help" for help.
postgres=#
我还可以使用您提供的连接字符串和postico进行连接:
差异微妙,我不确定restart政策在这里是否有任何区别,请尝试一下。
