Dreamhost to Docker Swarm and a site move

Whats up all…. It has been a while.

life happened.

the pandemic happened.

and i moved this site from dreamhost to a docker swarm setup (i will go over that setup in a later post)…

while configuring the compose file i decided that i should post it and also to explain that this version of the site was brought up fresh without a mysql backup / restore but rather i used the wordpress export / import tools to move stuff.

here is the docker compose i used :

version: "3"

services:
  wordpress:
    hostname: wordpress
    image: wordpress
    container_name: wordpress
    deploy:
      mode: global
      resources:
        limits:
          cpus: "2"
          memory: 512M
        reservations:
          memory: 256M
    ports:
      - 8080:80
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_USER: wp_user
      WORDPRESS_DB_PASSWORD: wp_pass
      WORDPRESS_DB_NAME: wordpress
    volumes:
      - "/path_to/wordpress:/var/www/html"

  db:
    hostname: mysql
    image: mysql
    container_name: mysql
    deploy:
      resources:
        limits:
          cpus: "2"
          memory: 1024M
        reservations:
          memory: 256M
    environment:
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wp_user
      MYSQL_PASSWORD: wp_pass
      MYSQL_RANDOM_ROOT_PASSWORD: '1'
    volumes:
      - "/path_to/mysql:/var/lib/mysql"

a few things to note :
– this is in docker swarm so hence the deploy section
– since this is swarm i decided to run the wordpress section itself in global
– the resource amounts chosen are still being graphed and tuned so YMMV
– i am using portainer to manage the docker installs

hopefully, with some testing and some more work i will get back to regularly posting and yelling into the void.
