azure - 在 CircleCI 中找不到 postgres_1 的容器

Question

我有一个circleCI脚本，它在Azure容器中运行docker-compose exec postgres pg_isready命令设置，但我们收到了代码构建错误，如下所示。相同的脚本早些时候运行良好，但从过去几天我们得到了这个。

running docker-compose up
Creating network "docker_default" with the default driver

过去一周使用相同的脚本成功构建。

这里的任何帮助都会很棒。

Answer 1

在您的docker-compose.yml文件中，请检查environment参数下是否提供了。如果未提供，请提供如下内容:- POSTGRES_HOST_AUTH_METHOD=trust。

这个解决方案对我们有用，导致此构建问题的原因应该是 Postgres 的 Docker 官方镜像最近已更新，这导致了以前工作的 PG 容器出现许多新问题现在在初始化时抛出错误。
