使用 docker-compose 运行时无法访问 Odoo 服务器

Question

我正在尝试使用docker-compose 。 我已按照此处的说明进行操作。 我可以使用 Docker 启动 Postgres 和 Odoo 服务器并正确访问 Odoo 服务器。 当我运行第一个“最简单”的docker-compose示例时，它似乎可以正确启动 Postgres 服务器，但几分钟后 web 服务器会出现一条错误消息：

docker-compose.yml完全从 docker 集线器页面复制，除了我注意到我安装了 Postgresql v14，因此我更改了 postgres 图像：

version: '3.1'
services:
  web:
    image: odoo:15.0
    depends_on:
      - db
    ports:
      - "8069:8069"
  db:
    image: postgres:14
    environment:
      - POSTGRES_DB=postgres
      - POSTGRES_PASSWORD=odoo
      - POSTGRES_USER=odoo

我已经使用 snap 在我的 Linux Mint 21 系统上安装了 Docker。 我这样做是因为这里的安装说明在我的系统上不起作用。

我现在已经能够安装 Docker Debian 包，这个问题就解决了。

为了正确安装 Debian package，我更改了：

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

至：

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  jammy stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
