Migrating a WordPress installation to Docker - getting a fresh WP install screen

Docker Desktop
1

Hi,

I am trying to migrate an existing WordPress installation from AMPPS to Docker on my local machine. Every time I visit the site after running docker-compose up I am confronted with a fresh WordPress install screen. My docker-compose.yml looks like this:

version: '3'

services:
  mysite-wp-db:
    image: mysql:5.7
    volumes:
      - ./db/initdb.d:/docker-entrypoint-initdb.d
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: wordpress
      MYSQL_USER: some_user
      MYSQL_PASSWORD: pwd

  mysite-wp:
    depends_on:
      - mysite-wp-db
    image: wordpress:latest
    restart: always
    expose:
      - "80"
    environment:
      - VIRTUAL_PORT=80
      - VIRTUAL_HOST=mysite.local
    volumes:
      - ./wp/wp-content:/var/www/html/wp-content
      - ./wp/wp-config.php:/var/www/html/wp-config.php

networks:
  default:
    external:
      name: mysite-nginx-proxy

I am running the site behind an nginx reverse proxy container. I have mysite.local mapped to 127.0.0.1 in /etc/hosts.

I populate the db from an sql dump file located under ./db/initdb.d (see the volumes: section of the mysql container above), and having also run a container with phpmyadmin in this stack I can confirm that it’s being copied over. So what am I doing wrong? Frustratingly I did have this working a few months ago.

Thanks

UPDATE: If I mount my entire WordPress installation directory to the container then it sort of works, but there are problems. So, I now have this:

      volumes:
          - ./wp:/var/www/html

where wp is the entrie WordPress folder, containing wp-config.php, wp-content, etc. I no longer get any errors, but when I access http://mysite.local I am always redirected to http://mysite.local/wp/. My AMPPS install was indeed under 127.0.0.1/wp, but I changed all of the links in my db text dump from that to mysite.local. Looking at the page source in the browser I can see that wp is being appended to mysite.local for all of the resources… if I remove it I can however access these resources - logos, JS files and CSS files, etc… it’s all there, just with wp added where it shouldn’t be… I don’t get this.

I have the standard .htaccess file in my wp folder, which looks like this:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

SOLVED: I had neglected to remove /wp from my 'siteurl' and 'home' entries in my database dump file… gah! It’s working now… although it seems only if I mount the entire original WordPress installation directory from AMPPS to var/www/html.

Sorry for the noise.
