AdonisJs - Presets

Start an AdonisJs Project with Docker in 3 Easy Steps

  1. Run kool create adonis my-project
  2. Update .env
  3. Run kool run setup

Yes, using kool + Docker to create and work on new AdonisJs projects is that easy!

Requirements

If you haven't done so already, you first need to install Docker and the kool CLI.

Also, make sure you're running the latest version of kool. Run the following command to compare your local version of kool with the latest release, and, if a newer version is available, automatically download and install it.

$ kool self-update

Please note that it helps to have a basic understanding of how Docker and Docker Compose work to use Kool with Docker.

1. Run kool create adonis my-project

Use the kool create PRESET FOLDER command to create your new AdonisJs project:

$ kool create adonis my-project

Under the hood, this command will run adonis new my-project to install the AdonisJs fullstack blueprint using a customized kool Docker image: kooldev/node:14-adonis.

After installing AdonisJs, kool create automatically runs the kool preset adonis command, which helps you easily set up the initial tech stack for your project using an interactive wizard.

$ Preset adonis is initializing!

? Which database service do you want to use [Use arrows to move, type to filter]
> MySQL 8.0
  MySQL 5.7
  PostgreSQL 13.0
  none

? Which cache service do you want to use [Use arrows to move, type to filter]
> Redis 6.0
  Memcached 1.6
  none

? Which javascript package manager do you want to use [Use arrows to move, type to filter]
> npm
  yarn

$ Preset adonis initialized!

Now, move into your new AdonisJs project:

$ cd my-project

The kool preset command auto-generated the following configuration files and added them to your project, which you can modify and extend.

+docker-compose.yml
+kool.yml

Now's a good time to review the docker-compose.yml file and verify the services match the choices you made earlier using the wizard.

2. Update .env

You need to update some default values in AdonisJs' .env file to match the services in your docker-compose.yml file.

We recommend you make the same changes in your .env.example file.

Host

-HOST=127.0.0.1
+HOST=0.0.0.0

Database Services

SQLite

If you selected "none" for database service when answering the preset wizard questions, and you decide to use AdonisJs' default SQLite database, you'll need to install the sqlite3 package and make this change (see "Connect to Docker Database Container" below for more info).

-DB_HOST=127.0.0.1
+DB_HOST=database

MySQL 5.7 and 8.0

-DB_CONNECTION=sqlite
+DB_CONNECTION=mysql

-DB_HOST=127.0.0.1
+DB_HOST=database

PostgreSQL 13.0

-DB_CONNECTION=sqlite
+DB_CONNECTION=pgsql

-DB_HOST=127.0.0.1
+DB_HOST=database

-DB_PORT=3306
+DB_PORT=5432

Cache Services

If you added a cache service to docker-compose.yml, you need to add these new environment variables, depending on which service you selected.

Redis

+REDIS_HOST=cache
+REDIS_PORT=6379

Memcached

+MEMCACHED_HOST=cache
+MEMCACHED_PORT=11211

3. Run kool run setup

Say hello to kool.yml, say goodbye to custom shell scripts!

As mentioned above, the kool preset command added a kool.yml file to your project. Think of kool.yml as a super easy-to-use task helper. Instead of writing custom shell scripts, add your own scripts to kool.yml (under the scripts key), and run them with kool run SCRIPT (e.g. kool run adonis). You can add your own single line commands (see adonis below), or add a list of commands that will be executed in sequence (see setup below).

To help get you started, kool.yml comes prebuilt with an initial set of scripts (based on the preset), including a script called setup, which helps you spin up a project for the first time.

scripts:
  adonis: kool exec app adonis
  npm: kool exec app npm # or yarn
  npx: kool exec app npx

  setup:
    - kool docker kooldev/node:14 npm install # or yarn install
    - kool start

Go ahead and run kool run setup to start your Docker environment and finish setting up your project:

$ kool run setup

As you can see in kool.yml, the setup script will do the following in sequence: run npm install to build your Node packages and dependencies (by spinning up and down a temporary Node container); and then start your Docker environment using docker-compose.yml (which includes a command to automatically run adonis serve --dev).

Once kool run setup finishes, you should be able to access your new site at http://localhost:3333 and see the AdonisJs "It works!" welcome page. Hooray!

Verify your Docker container is running using the kool status command:

$ kool status
+---------+---------+------------------------+--------------+
| SERVICE | RUNNING | PORTS                  | STATE        |
+---------+---------+------------------------+--------------+
| app     | Running | 0.0.0.0:3333->3333/tcp | Up 5 seconds |
+---------+---------+------------------------+--------------+

Run kool logs app to see the logs from the running app container, and confirm the AdonisJs server was started.

Use kool logs to see the logs from all running containers. Add the -f option after kool logs to follow the logs (i.e. kool logs -f app).

$ kool logs app
Attaching to my-project_app_1
app_1  |
app_1  |  SERVER STARTED
app_1  | > Watching files for changes...
app_1  |
app_1  | info: serving app on http://0.0.0.0:3333

Run Commands in Docker Containers

Use kool exec to execute a command inside a running service container:

# kool exec [OPTIONS] SERVICE COMMAND [--] [ARG...]

$ kool exec app node -v

Try kool run adonis --help to execute the kool exec app adonis --help command in your running app container and print out information about AdonisJs' commands.

Open Sessions in Docker Containers

Similar to SSH, if you want to open a Bash session in your app container, run kool exec app bash, where app is the name of the service container in docker-compose.yml. If you prefer, you can use sh instead of bash (kool exec app sh).

$ kool exec app bash
bash-5.1#

$ kool exec app sh
/app #

Connect to Docker Database Container

You'll need to install the appropriate Node packages to use a database service. For example, to use AdonisJs' default SQLite database, you'll need to add the sqlite3 package by running kool run npm install sqlite3 --save (or kool run yarn add sqlite3 --save), after which you can call kool run adonis migration:run to run migrations (and don't forget to change DB_HOST to database in your .env file).

If you added a database service, you can easily start a new SQL client session inside your running database container by executing kool run mysql (MySQL) or kool run psql (PostgreSQL) in your terminal. This runs the single-line mysql or psql script included in your kool.yml.

Access Private Repos and Packages in Docker Containers

If you need your app container to use your local SSH keys to pull private repositories and/or install private packages (which have been added as dependencies in your package.json file), you can simply add $HOME/.ssh:/home/kool/.ssh:delegated under the volumes key of the app service in your docker-compose.yml file. This maps a .ssh folder in the container to the .ssh folder on your host machine.

volumes:
  - .:/app:delegated
+ - $HOME/.ssh:/home/kool/.ssh:delegated

Staying kool

When it's time to stop working on the project:

$ kool stop

And when you're ready to start work again:

$ kool start
