xdebug - failed to solve with frontend dockerfile.v0: failed to create LLB definition: dockerfile parse error line 45: unknown instruction: ZEND_EXTENSION=XDEBUG.SO

How I got here

Running the following Docker command

docker-compose up

Generated this output:

Running Docker

Dangerous word... I'm assuming that Docker is installed.  Don't know how to check?  Using Terminal (I prefer iTerm2), run the following command

docker -D info

The set-up

Go to your project directory, and create a docker folder and a “docker-compose.yml” file:

Is Docker installed?

Check if your installation is ok and spin up Docker as well:

docker -D info

Using Docker

Now it's time to download and install docker images. Using the official images of MariaDB and Drupal. If you don’t specify the absolute URL to the image it will be searched and downloaded from Docker Hub. Tag 'latest' will be used by default.

In terminal I ran a regular command - compose update.  Something I've completed thousands of times previously.  However, this time I received the following response:

env: php: No such file or directory

Create and push to Docker Hub

Creating your own custom image... you need to have a Docker ID.  Not sure, well most likely you created it to download Docker Desktop.  If you don't have one, go to Docker and sign up.

In your  text editor create a file called Dockerfile in the same directory you want to have as your local site. No extension, just Dockerfile. Paste in this code and save the file:

If you are using theme_get_settings, such as:

$value = trim(theme_get_setting('my_setting'));

Then in your code editor you will also be seeing undefined  function 'theme_get_setting'.  This function has been deprecated for some time.

Running composer on a server... when running the command composer update, screen would error out.  In the site directory, composer would show 

composer --version

Composer version 1.10.24 2021-12-09 20:06:33

Whereas, the commnd

/opt/plesk/php/7.4/bin/php /usr/lib64/plesk-9.0/composer.phar --version

Composer version 2.2.5 2022-01-21 17:25:52

Ok, so composer on the server is running 2.2x.  But on my site directory, 1.x

Resetting Docker is basically following the start parameters.  All containers removed -

No containers running

Try running a container: Copy and paste this command into your terminal

docker run -d -p 80:80 docker/getting-started

Unable to find image 'docker/getting-started:latest' locally
latest: Pulling from docker/getting-started

Adding basic security to your server, requires altering the security.json file.  For me this file was located

/var/solr/data/

Add a User or Edit a Password

The set-user command allows you to add users and change their passwords. For example, the following defines two users and their passwords:

What am I setting out to achieve?

I want to meet the following requirements:
