SMT Laravel Demo App

To get started with this Laravel 7 demo application smt you can clone the application using:

git clone `https://github.com/smart48/smt-demo.git`

Installation

Generate Auth Key and .env

php artisan key:generate

Packages

composer install to install all PHP packages and npm install for the JS and Vue parts.

Migrations

Then migrations using php artisan migrate --database="nameOfConnection". We use --database as we work with two databases locally and in Kubernetes. So we have

  • php artisan migrate --database="mysql" for base database
  • php artisan migrate --path=/database/migrations/published --database="mysql_published for the secondary.

As of this writing the secondary database is still empty

NB Quick rollback php artisan migrate:reset

Laradock

Laradock based submodule has been added using git submodule add https://github.com/smart48/smt-docker.git and can be used from that folder.

The Laradock env.smt.example has been set up to work with:

  1. Workspace,
  2. PHP FPM,
  3. PHP Worker,
  4. Nginx,
  5. Laravel Horizon,
  6. Redis,
  7. MariaDB x 2,
  8. MailDev,

Rename it to .env to work with it inside your project.

Locally we work with docker-compose.yml inside the Laradock subdmodule folder. You can run this with docker-compose.yml up -d. See Docker docs . We do not use the default docker-compose.yml as we want to be able to update the submodule with ease when need be.

Note: All the web server containers nginx, apache ..etc depends on php-fpm, which means if you run any of them, they will automatically launch the php-fpm container for you, so no need to explicitly specify it in the up command. If you have to do so, you may need to run them as follows: docker-compose up -d nginx php-fpm mysql.

NB We use port 9090 for http and 4433 for https for Nginx and 3307 and 3308 for MariaDB to avoid conflicts with Valet.

docker-compose up -d

And to shut them down

docker-compose down

List Containers

docker container ls

Infrastructure

To set up Kubernetes with nodes and managed databases at Digital Ocean we use Terraform and Kubernetes. The package is added using git submodule add https://github.com/smart48/smt-provision.git

cd smt-provision
terraform init

You should see something like

Initializing the backend...

Initializing provider plugins...
- Checking for available provider plugins...
- Downloading plugin for provider "helm" (hashicorp/helm) 1.2.1...
- Downloading plugin for provider "digitalocean" (terraform-providers/digitalocean) 1.18.0...

The following providers do not have any version constraints in configuration,
so the latest version was installed.

To prevent automatic upgrades to new major versions that may contain breaking
changes, it is recommended to add version = "..." constraints to the
corresponding provider blocks in configuration, with the constraint strings
suggested below.

* provider.digitalocean: version = "~> 1.18"
* provider.helm: version = "~> 1.2"
* provider.null: version = "~> 2.1"

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

Terraform Test

To check if the files will do their job you can run a test. But first add smt-provision/terraform.tfvars with

do_token = "key"
spaces_access_id = "access_key"
spaces_secret_key = "secre_key"
region = "ams3"
email = "jasper@imwz.io"
state_bucket = "tfstate"
helm_enabled = "true"
helm_nginx_ingress_classes = ["nginx-class-1"]
helm_nginx_ingress_replica_counts = ["2"]
kubernetes_name = "smt1"
name = "smt1"
kubernetes_context = "smt1"
kubernetes_version = "1.17.5-do.0"
kubernetes_node_size = "s-1vcpu-2gb"
# kubernetes_node_count = ""
kubernetes_autoscale = "true"
kubernetes_min_nodes = 1
kubernetes_max_nodes = 2
mysql_version ="8"
mysql_instances = ["smt1_mysql"]
mysql_node_sizes = ["db-s-1vcpu-2gb"]
mysql_node_counts = ["1"]
redis_version = "5"
redis_instances = ["smt1_redis"]
redis_node_sizes = ["db-s-1vcpu-2gb"]
redis_node_counts = ["1"]

and make sure to add your own Digital Ocean keys. Once done you can run:

terraform plan

to do a test run.
