404 when attempting to access admin panel behind reverse proxy

[eric-at-nocoast]

Going to preface this with the fact that I'm very new to working with Docker so it's very possible I'm missing something, any help would be appreciated.

After building an image using the example Dockerfile behind a reverse proxy, I receive a 404 when trying to access the admin panel.

Additionally though the index page loads, it is missing the "Create admin" button

Dockerfile:

FROM strapi/base

WORKDIR /srv/app

COPY ./app/package.json ./
COPY ./app/yarn.lock ./

RUN yarn install

COPY ./app /srv/app

ENV NODE_ENV production

RUN yarn build

EXPOSE 1337
CMD ["yarn", "start"]

Hi, I'm running into the exact same issue. Have you managed to resolve it?

[eric-at-nocoast]

Hey @artfurma,

I had to switch to a subdomain approach to get this functioning. I couldn't get the sub folder approach to function with the application being dockerized.

@eric-at-zd so basically, this is still a bug and you just switched away from this approach of sub folder. So this should still be an issue? Because im having the same problem and either the official Strapi documentation is faulty or incomplete
