Symfony 5, development and deploy stack

 Keywords: Symfony 5, PHP7.4, Apache 2.4, Postgres 10.4, Docker, Kubernetes, cli, https, Ingress

All commands are run in the root directory.

Config files

Path	Usage
./.env	build env variables for build via docker-compose
./app/.env	app env variables for local development
./app/.env.test	app env variables for test development

Prod ENVs are defined in ./kubernetes/init/secrets.yaml!

Local development

Remote postgres db (no-persist), apache listening on localhost:80 and php-fpm

$ ./cli start
$ ./cli stop

Predefined app commands

CLI shortcut (within manually connecting to container):

$ ./cli tests           <-- all tests
$ ./cli tests ecs       <-- only ecs
$ ./cli tests phpstan   <-- only phpstan
$ ./cli tests phpunit   <-- only phpuni

Or run composer commands / symfony commands in webroot directory in PHP container:

$ composer ecs          <-- code style check
$ composer ecs-fix      <-- code style check with auto-fix
$ composer phpstan      <-- php static analyst
$ composer phpunit      <-- classic phpunit tests

Useful commands

$ ./cli bash            <-- return bash from php-fpm container

Push docker images to GitHub registry

Enable docker container registry for your account

1. go to https://github.com/settings/tokens and generate new token for "repo", "write:packages", "read:packages"
2. on github.com click to your account -> Feature preview and click to "Enable"

Acces to github private registry from localhost

On your localhost run command (as password paste token from first step):

$ docker login ghcr.io -u [github_username]

Access to github private registry from Kubernetes

kubectl create secret docker-registry regcred \
    --docker-server=ghcr.io \
    --docker-username=[github_username] \
    --docker-password=[token_from_first_step] \
    --namespace [githubusername/github_project]

Great! You have github docker registry. Your images you can find on your github profile under "Packages" tab.

This project has GitHub actions for automatic build php-fpm and apache with save images on GitHub.

Set GitHub SECRETS for your project -> need for automatic build and deploy

1. on github in project settings click to Secrets
2. click to New repository secret and create two keys with this names:

File	Description
KUBE_CONFIG_DATA	contains base64 encode KUBECONFIG file for access your Kubernetes
CR_PAT	with token for image repository (from previous step)

Init production

Set Kubernetes namespace

All configs use namespace attribute. Namespace is generated from your github username/repo (repo must be cloned with git), for example:

Repo: git@github.com:kdosiodjinud/symfony-docker.git
Generated namespace: kdosiodjinud-symfony-docker

Becouse project is universal, you must init script for replace namespaces in your cloned version:

./cli init

That`s all! :)

Services

Look at the kubernetes/init/secrets.yaml file and config your settings for production. After check apply configure all files from folder init:

kubectl apply -f kubernetes/init/

Ingress (domain routing) and HTTPS

Install cert manager to Kubernetes cluster

This example is for Kubernetes over microk8s service, but commands for full install kubernetes is the same. In file ingress/cert.yaml set your email address. In file ingress/ingress.yaml set domain for your app.

// run in cluster
$ microk8s enable helm3 ingress
$ microk8s kubectl create namespace cert-manager
$ microk8s helm3 repo add jetstack https://charts.jetstack.io
$ microk8s helm3 repo update
$ microk8s helm3 install cert-manager jetstack/cert-manager \
  --namespace cert-manager --version v0.15.2 \
  --set installCRDs=true \
  --set ingressShim.defaultIssuerName=letsencrypt-production \
  --set ingressShim.defaultIssuerKind=ClusterIssuer \
  --set ingressShim.defaultIssuerGroup=cert-manager.io

// run from localhost
$ kubectl apply -f kubernetes/ingress/

Deploy to production

If you have ready app, push it to github. Init realease is realy easy. Make git tag with prefix r(for example r0.0.1).

After github register tag, github actions run tests, build images and make deploy to Kubernetes.

Create new commands for app CLI

This project use great simple framework for generate CLI:https://github.com/DannyBen/bashly

Thank you Danny :)

Path to sources files:

./cli-src/

New commands you can define in yml file:

./cli-src/src/bashly.yml

After edit you must run:

./cli-src/bashly generate 

Bashly create new *.sh files in ./cli-src/src/ directory - this is place for process your new command logic. After update run generate again!

In app root is symlink for easy call CLI:

./cli --help
