strapi-docker: Successful installation with Docker... But I can't access Strapi through my browser !

My install seems successful, but I can’t access through my browser. I tried every installation method possible in Docker with always the same result.

I don’t know if it is an issue or juste me >_<

1/4 The Screen I get:

2/4 The Installation

Tools

Strapi … 3.0.0-beta.19.4
Mango … 4.2.5
Mac … Mohave 10.14.6 (18G95)
Docker … 2.2.0.4 (43472)

Steps/Procedures (For each Docker version mentioned below)

Installed latest version of Docker
I tried with the Instructions from your website: strapi.io/documentation/3.0.0-beta.x/installation/docker.html With both the docker-compose.yaml on your website and docker git repo (they are not the same)
And I tried with the Instructions from your Docker Repo: https://hub.docker.com/r/strapi/strapi Nothing seems to work in Docker …

Installation Types

Docker Latest Version w/ the guide on strapi website doc … ⛔️ Failed Docker Latest Version w/ the guide on docker strapi repo … ⛔️ Failed Docker Older version (2.0) w/ the guide on strapi website doc … ⛔️ Failed Docker Older version (2.0) w/ the guide on docker strapi repo … ⛔️ Failed CLI with SQLite … ✅ Success 🧐

I had to try with CLI… the problem seems to be with either Docker or the Docker Branch 😕

Url entered for the admin that point to the error page (image above)

localhost:1337/admin
127.0.0.1:1337/admin

On the other hand, CLI installation is working…!

3/4 The docker-compose.yaml file:

Basically this file: https://github.com/strapi/strapi-docker/blob/master/examples/mongo/docker-compose.yml

services:
  strapi:
    container_name: strapi
    image: strapi/strapi
    environment:
      - DATABASE_CLIENT=mongo
      - DATABASE_HOST=db
      - DATABASE_PORT=27017
      - DATABASE_NAME=strapi
      - DATABASE_USERNAME=
      - DATABASE_PASSWORD=
      - DATABASE_AUTHENTICATION_DATABASE=strapi
    ports:
      - 1337:1337
    volumes:
      - ./app:/srv/app
    depends_on:
      - db

  db:
    container_name: mongo
    image: mongo
    environment:
      - MONGO_INITDB_DATABASE=strapi
    ports:
      - 27017:27017
    volumes:
      - ./db:/data/db
    restart: always

I found the issue. It is coming from the host configuration in config/environments/{env}/server.json to run correctly in docker you will need to set it to 0.0.0.0

alexandrebodin on Mar 31, 2020

So I did the following and it worked for me:

Standard install using mango db docker-compose in your git
Changed "host": "localhost" to "host": "0.0.0.0"
Went on 127.0.0.1:1337/admin/ instead of localhost:1337/admin/

So amazing! With my actual level of knowledge of the development, I would never found out that solution!

One more question! Is this solution considered as a fix, a hack or normal thing to do under docker? I am asking this as on a CLI install, localhost works fine!

Thanks

@mannp to give you full context:

In prior versions of 19.3 the host wasn’t used to set the server listening so it always defaulted to 0.0.0.0 behind the scene.

This was fixed in 19.4 but the default value became localhost and thus broke deploys on docker or other containerized envs (heroku…)

Ideally we will put localhost back for users that do not use docker and use a HOST env var inside of our docker images so the env is only changed inside docker 😃

Hope this gives you the full picture!

Just released the new docker images with a fix for this host thing when creating a new project.

Closing this issue. Feel free to comment if you still are having problems when creating a new project 😃

FYI: After changing the server.json to ‘0.0.0.0’ I had to then visit 127.0.0.1/admin to load the admin panel, NOT localhost/admin
