Updating Wordpress

General
1

I’ve used Brad Traversy’s YT video ‘Quick Wordpress Setup With Docker’ to get a WP up and running (see code below). But there is still a lot I don’t understand. I’ve got my WP site up and running but I’ve got WP telling me there are updates available, before I ask my main question, I’d like to clear something up.

I’ve got a local folder which is mapped to another folder in the container and they sync up. Am I right in assuming that if WP updates (via my WP Admin console http://localhost:8000/wp-admin), it’s actually updating my local folder, which in turn will update WP in the container since they are set up to sync with each other?

http://localhost:8000/ gives me access to the site.

Currently if I try to update this is what I see in the WP console

After watching countless videos I found an answer:

  • To update WP to a later version go into your yml file set the version you want.

  • Then just issue the following command:
    docker-compose up -d wordpress

  • Then go into your WP admin console and select ‘upgrade’

It’s easier solution.

You have to edit wp-config.php file by add define('FS_METHOD','direct'); to the end of file.
Save the file and run update. From now, you don’t need FTP server to update your WordPress.
Remember! Before update make a backup :slight_smile:

How can setup WordPress to docker and what is the process.

on your yml file, you don’t need to map the whole wordpress folder
volumes: [‘./:/var/www/html’]

wp-content folder is enough
volumes: [‘./wp-content:/var/www/html/wp-content’]

And to update wordpress, especially if you are using the latest tag, issue the following command

docker pull wordpress

This will update the wordpress image on your machine
Finally, spin up the service by
docker compose up -d
