+# Docker
+
+This project relies in the following 3 application images:
+
+* [php.package.health/nginx](docker/nginx.Dockerfile): Serves static assets (css, fonts etc) and routes dynamic traffic to php-fpm;
+* [php.package.health/php-fpm](docker/php.Dockerfile): Serves dynamic traffic based in the application code;
+* [php.package.health/php-cli](docker/php.Dockerfile): Used to perform maintenance tasks, such as database migration.
+
+## Building the base images
+
+From the root directory of this repository:
+
+```bash
+docker build --file docker/nginx.Dockerfile --tag php.package.health/nginx:latest .
+docker build --file docker/php.Dockerfile --target fpm --tag php.package.health/php-fpm:latest .
+docker build --file docker/php.Dockerfile --target cli --tag php.package.health/php-cli:latest .
+```
+
+## Creating a network
+
+The network will be shared by the containers so they can communicate without exposing ports to the host machine.
+
+```bash
+docker network create php-package-health-network
+```
+
+## Starting the containers
+
+Start the database container:
+
+```bash
+docker run \
+  --detach \
+  --env-file "$(pwd -P)/.env" \
+  --volume "$(pwd -P)/var/db":/var/lib/postgresql/data \
+  --network php-package-health-network \
+  --name pph-postgres \
+  postgres:14.2-alpine3.15
+```
+
+Start the PHP-FPM container:
+
+```bash
+docker run \
+  --rm \
+  --detach \
+  --env-file "$(pwd -P)/.env" \
+  --network php-package-health-network \
+  --name pph-php-fpm \
+  php.package.health/php-fpm:latest
+```
+
+Start the NGINX container:
+
+```bash
+docker run \
+  --rm \
+  --detach \
+  --network php-package-health-network \
+  --publish 8080:80/tcp \
+  --name pph-nginx \
+  php.package.health/nginx:latest
+```
+
+## Database Migration
+
+Start the PHP-CLI container:
+
+```bash
+docker run \
+  --rm \
+  --interactive \
+  --tty \
+  --env-file "$(pwd -P)/.env" \
+  --network php-package-health-network \
+  --name pph-php-cli \
+  php.package.health/php-cli:latest \
+  sh
+```
+
+Check migration status:
+
+```bash
+../vendor/bin/phinx status --configuration ../phinx.php --environment "${PHP_ENV}"
+```
+
+Run migrations:
+
+```bash
+../vendor/bin/phinx migrate --configuration ../phinx.php --environment "${PHP_ENV}"
+```
+
+## Accessing the application
+
+Open your browser and head to [http://localhost:8080/](http://localhost:8080/).
+
+## Maintenance
+
+The following sections are dedicated to maintenance tasks only.
+
+### Application Console
+
+Start the PHP-CLI container:
+
+```bash
+docker run \
+  --rm \
+  --interactive \
+  --tty \
+  --env-file "$(pwd -P)/.env" \
+  --network php-package-health-network \
+  --name pph-php-cli \
+  php.package.health/php-cli:latest \
+  sh
+```
+
+List console commands:
+
+```bash
+php console.php
+```
+
+### PostgreSQL Command Line Interface (PSQL)
+
+Execute `sh` in the running `pph-postgres` container:
+
+```bash
+docker exec \
+  --interactive \
+  --tty \
+  pph-postgres \
+  sh
+```
+
+Run `psql`:
+
+```bash
+psql \
+  --username "${POSTGRES_USER}" \
+  --dbname "${POSTGRES_DB}"
+```
