问题描述
我正在使用上述组件部署应用程序。我正在部署一个 django/gunicorn 应用程序,使用 Nginx,使用 docker-compose。
它基于前端模板 (sb-admin),该模板在 sb-admin-2.min.css 中定义。我在 mystyle.css 中覆盖/补充了它。
基本上我构建我的图像,将它们推送到我的 dockerhub。然后我部署它们(通过使用 docker-compose pull 拉取图像),并使用 docker-compose up --no-build 运行它们(只是为了确保)。
您可以查看结果以及控制台详细信息。右边是本地部署,左边是linode。您可以从控制台看到两个加载 mystyle.css 的 GET 200 OK 响应(在加载 sb-admin-2.min.css 之后)。然而不知何故,结果在 linode 上的实际服务器部署上有所不同。
我试过了:
- 从头开始多次。例如。我已经删除了 linode 服务器和本地机器上的所有容器/图像。然后我在本地重新构建它们,将它们推送到 dockerhub。然后拉动它们(在本地和 linode 上)。然后部署并访问页面 - 结果有些不同。我很漂亮,我正在拉/推/跑我认为我应该做的事情。
我什至不太确定如何解决这个问题 - 显然部署有效,但为什么结果不同?我应该如何调试这个?
dockerfile:
version: '3.9'
services:
django:
# since both build: & image: are present,the result of the build: instruction will be called whatever name we assign to image:
image: franckit/${DJANGO_IMG_NAME}
build:
# everything relevent to that built is within /app
context: ./app
# specifying the Dockerfile to use,as it is not named Dockerfile
dockerfile: Dockerfile.prod
args:
- "VERSION=${DJANGO_IMG_VERSION}"
# using gunicorn as our webserver in front of Docker (manage traffic)
command: "gunicorn myproject.wsgi:application --bind ${DJANGO_IP}:${DJANGO_PORT}"
# expose only makes the port available on the Docker virtual network. Dfeault for django is 8000 so we'll just use that
expose:
- "${DJANGO_PORT}"
# we'll dump the (runtime) envars in there. to user buildtime envars,see this issue: https://stackoverflow.com/questions/64405332/docker-compose-env-file-only-loading-env-but-not-a-specific-name/64436008#64436008
# short story being that you MUST name a file .env if you are to use those as build-time envars
