Deployment

The easiest way to deploy your pckg app is by using Docker Compose. The example below shows you how to run a multiple stacks with:

HAProxy + Letsencrypt at entrypoint
MySQL, Redis and RabbitMQ as a system services
Apache + PHP for the web/app server

Docker Compose (Swarm)

Entrypoint

Entrypoint is only needed in production environment.

 docker stack deploy local-project--entrypoint \
 -c docker-compose.entrypoint.yml \
 -c docker-compose.entrypoint.prod.yml \
 --with-registry-auth --prune --resolve-image always

 env VOLUME_DATABASE_KEY=local-project--system--database \
 env VOLUME_CACHE=/local/local-project--system--cache \
 env VOLUME_CACHE_KEY=local-project--system--cache \

 docker stack deploy local-project--system \
 -c docker-compose.system.yml \
 -c docker-compose.system.prod.yml \
 --with-registry-auth --prune --resolve-image always

Deploy app.

$ env CONFIG_WWW=/www/client/project.local/htdocs/.env
 env CONFIG_WWW_KEY=local-project--www
 env CONFIG_APACHE=/www/client/project.local/htdocs/storage/apache.conf
 env CONFIG_APACHE_KEY=local-project--apache

 docker stack deploy local-project--www \
 -c docker-compose.www.yml \
 -c docker-compose.www.prod.yml \
 --with-registry-auth --prune --resolve-image always

Production

You need to pack your code first.

$ docker build \
 -f docker/build/Dockerfile \
 -t registry.digitalocean.com/team/project:$GITHUB_SHA \
 .

FROM schtr4jh/pckg:apache-fpm-80-alpine

COPY . /var/www/html

ENTRYPOINT ["sh", "/docker-entrypoint-apache-fpm-80.sh"]

Development

Run temp docker container with Apache + PHP FPM + MySQL + Redis + Composer + Yarn + Webpack + a lot more.

$ docker run \
 -v /path/to/project/:/var/www/html \
 -i -p 8089:443 \
 -t schtr4jh/pckg:latest \
 -e PCKG_EMAIL="your@email.net" \
 -e PCKG_NAME="John Doe" \
 --restart=always /bin/bash

CLI (with Docker Compose - Swarm)

If you have installed Pckg CLI, you can use it to automatically deploy your app to the local/dev environment or remote environment by providing SSH keys.

$ pckg-cli config:memorize --name project.local --reverse local-project --host localhost
$ # pckg-cli deploy --image haproxy:letsencrypt
$ pckg-cli deploy --image mysql:8.0
$ pckg-cli deploy --image redis
$ pckg-cli deploy --image rabbitmq
$ pckg-cli deploy --image apache2
$ pckg-cli deploy --image php:8.0
