通过docker加载postgres的命令？ [英] Command for loading postgres through docker?

问题描述

有人知道通过docker加载postgres的命令吗？以下是其文档上的推荐命令：

Does anyone know the command for loading postgres through docker? Here is the recommended command on their documentation:

docker run -it --rm --network some-network postgres psql -h some-postgres -U postgres

请忽略天真的问题，如何找到 some-network的值和 some-postgres的值？ / p>

Forgive the naive question, how do you find what values for "some-network" are supposed to be and what values "some-postgres" is supposed to be?

推荐答案

好，我知道了。我的命令在技术上是正确的，但是postgres需要几秒钟来加载服务器。在这种情况下，postgres客户端才能连接到服务器！这些命令适用于我的系统：

Ok, I figured it out. My command was technically correct, but postgres takes a few seconds to load the server. The postgres client can't connect to the server until this happens! These commands worked for on my system:

docker run -e POSTGRES_PASSWORD=password  -it --rm postgres

docker ps
(get container_id from this)

docker exec -it container_id  psql -h localhost -U postgres
