我正在尝试使用Docker并希望将Postgres容器化。
我按照官方示例进行操作,但无法使用psql连接到正在运行的镜像。
我创建了一个包含示例内容的Dockerfile。我从Dockerfile构建了一个镜像,并为其分配了名称。然后我运行了PostgreSQL服务器容器(在前台)。
~/test » docker run --rm -P --name pg_test eg_postgresql
2014-10-10 06:12:43 UTC LOG: database system was interrupted; last known up at 2014-10-10 06:12:29 UTC
2014-10-10 06:12:43 UTC LOG: database system was not properly shut down; automatic recovery in progress
2014-10-10 06:12:43 UTC LOG: redo starts at 0/1782F68
2014-10-10 06:12:43 UTC LOG: record with zero length at 0/1782FA8
2014-10-10 06:12:43 UTC LOG: redo done at 0/1782F68
2014-10-10 06:12:43 UTC LOG: last completed transaction was at log time 2014-10-10 06:12:29.2487+00
2014-10-10 06:12:43 UTC LOG: database system is ready to accept connections
2014-10-10 06:12:43 UTC LOG: autovacuum launcher started
然后我打开另一个终端来查找端口:
~/test » docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
aaedb0479139 eg_postgresql:latest "/usr/lib/postgresql 3 days ago Up 41 seconds 0.0.0.0:49154->5432/tcp pg_test
所以我可以使用psql连接到实例。但是我不能...
~/test » psql -h localhost -p 49154 -d docker -U docker --password
Password for user docker:

非常感谢您的帮助。
