我尝试使用 postgres 插件设置无人机服务器，但我完全无法让它工作。
我所做的是从文档中复制默认的无人机设置：
---
kind: pipeline
type: docker
name: default
steps:
- name: test
image: postgres:9-alpine
commands:
- sleep 5 #give the service some time to start
- psql -U postgres -d test
services:
- name: database
image: postgres:9-alpine
environment:
POSTGRES_USER: postgres
POSTGRES_PASSWORD: password
POSTGRES_DB: test
但是我在尝试启动它时收到以下错误
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
我的猜测是，由于某种原因，postgres没有开始，但很难说。
这是Postgres日志：
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".
Data page checksums are disabled.

You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
Success. You can now start the database server using:
pg_ctl -D /var/lib/postgresql/data -l logfile start

无论是那个还是Postgres启动正常，但在其他进程有机会通信之前，有些东西会杀死它。不过我不完全确定。
任何帮助将不胜感激。
Drone 在自己的容器中启动具有自己主机名的服务。
在您的情况下，您database命名了服务，因此在与psql连接时，您需要传递主机名，以便psql通过 TCP 与容器建立连接：
psql -U postgres -d test -h database
