在 CircleCI 中找不到 postgres_1 的容器

Question

我有 circleCI 脚本，其中运行s docker-compose exec postgres pg_isready 命令在 Azure 容器中设置，但我们收到代码构建错误，如下所示。相同的脚本之前运行宁没问题，但从过去几天我们得到这个。

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

上周使用相同脚本成功构建。

撰写文件

services:
  myproject:
    image: myproject:latest
    environment:
      - CONFIG_ENV=ci
      - CONFIG_PASSWORD
      - POSTGRES_HOST=postgres
  postgres:
    image: postgres:9.6
    environment:

这里有任何帮助都将非常有用。

Answer 1

在您的 docker-compose.yml 文件中，请检查是否在 environment 参数下提供。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，这个构建问题的原因应该是 Docker Postgres 的官方图像最近更新了，这导致了以前的一系列新问题正在工作的 PG 容器现在在初始化时抛出错误。
