Database

The database must be placed in the postgresql/gln_pg_initdb folder, to be imported during the construction of the PostgreSQL container.

├───postgresql
│   └───gln_pg_initdb        

Variables

Before starting the containers, at the root of the Docker project, please copy the .env.default file, renaming it .env, then replace the varibales as you wish. To test the project, you can leave the default variables.

# For deploy
ENV_ID=develop
# Drupal
DRUPAL_HOST=learn.mm
DRUPAL_TAG=1.0.0
DRUPAL_VERSION=9.3.8
DRUPAL_PORT=8076
DRUPAL_SITE_EMAIL=yeah@hello.mm
DRUPAL_SITE_NAME=Learn Drupal 9
# Drupal BO (For information only, so as not to forget :)
DRUPAL_SITE_ADMINISTRATOR=admin
DRUPAL_SITE_ADMINISTRATOR_PASS=admin

...

Run container

• At the root of the project, launch the docker compose.

docker compose up -d --build

• The docker ps command to list containers.

docker ps

Composer and Drupal php dependencies

For development environment

When you have launched your containers, execute the container of the application in order to download the php dependencies of Drupal with composer.

docker exec -it learnapp bash

Then in the container, at the root of the /opt/drupal folder, I run composer install.

composer install

For the production environment

For the production environment, the composer install is launched in the Dockerfile script

# Install composer stuff
RUN composer install --no-dev

Build the image for a production context

For the build of the image and the deployment of the container:

• I go to the root of the project and I run the following command.

docker build -f ./config/production/Dockerfile -t learn/app/d9.3.8:1.0.1 --no-cache .

Command description

• We tell Docker which Dockerfile to use

-f ./config/production/Dockerfile 

• Then the name and the tags of the image

-t learn/app/d9.3.8:1.0.1

• We ask docker not to use caches

--no-cache

• We indicate the root location of the files to add in the images.
