 # Docker Kit
 
-The humble kit with configuration files of Docker Compose for web development. Inside you can find the next configurations of virtual hosts:
+The humble kit with configuration files of Docker for a web development. Inside you can find simple web applications in JavaScript, Python and PHP.
 
-#### Nginx
-- Simple PHP web application
-- WordPress
-- Yii 2 (advanced application template)
-- Yii 2 (basic application template)
+## Installation
 
-#### Apache
-- Yii 2 (advanced application template)
+Try it out by the following steps.
 
-## Setup
-
-For example, set the kit to Ubuntu 16.04 x64 (with 512 MB RAM). You should add the swap space and install Docker Compose.
-
-1. Create and enable the swap file equal 2xRAM:
-```bash
-$ sudo fallocate -l 1G /swapfile
-$ sudo chmod 600 /swapfile
-$ sudo mkswap /swapfile
-$ sudo swapon /swapfile
-```
-2. Make the swap file permanent by adding it to the `/etc/fstab` file:
-```bash
-$ echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
-```
-3. Modify kernel setting:
-```bash
-$ sudo sysctl vm.swappiness=10
-$ sudo sysctl vm.vfs_cache_pressure=50
-$ sudo sysctl vm.overcommit_memory=1
-$ sudo sysctl vm.overcommit_ratio=80
-```
-4. Set Docker memory limits:
-```bash
-$ echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/default/grub
-$ sudo update-grub
-```
-5. Restart the system:
-```bash
-$ sudo shutdown -r now
-```
-6. Install Docker and Docker Compose (by default `docker-compose.yml` is configured for nginx, you can change it):
+1. Download and install [Docker Engine](https://docs.docker.com/engine/install/) and [Docker Compose](https://docs.docker.com/compose/install/).
+> **Note:** Docker Compose should be install for all users into the `/usr/local/lib/docker/cli-plugins/docker-compose` directory.
+2. Clone the repository:
 ```bash
-$ curl -sSL get.docker.com -o docker-setup.sh
-$ sh docker-setup.sh
-$ rm docker-setup.sh
-$ curl -L https://github.com/docker/compose/releases/download/1.23.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
-$ chmod +x /usr/local/bin/docker-compose
+$ cd /home/
+$ git clone https://github.com/mickgeek/docker-kit.git
 ```
-7. Clone the repository **into a directory with path `/srv/docker`**:
+3. Copy `.env.example` to `.env` and then edit the file according to needs:
 ```bash
-$ git clone https://github.com/mickgeek/docker-kit.git /srv/docker
+$ cp /home/docker-kit/docker/.env.example /home/docker-kit/docker/.env
 ```
-8. Copy `.env.example` to `.env` and then edit the file according to needs:
+4. Start up the containers:
 ```bash
-$ cp /srv/docker/.env.example /srv/docker/.env
+$ cd /home/docker-kit/docker/
+$ docker compose up
 ```
-9. Add the service to system startup:
+
+## Tips
+
+### Service of the system startup
+
+To add the service to the system startup (Ubuntu 16.04), you should execute the next commands:
 ```bash
-$ cp /srv/docker/docker-compose-app.service /etc/systemd/system/
-$ sudo systemctl enable docker-compose-app
-$ sudo systemctl start docker-compose-app
+$ cp /home/docker-kit/docker/docker-kit.service /etc/systemd/system/
+$ sudo systemctl enable docker-kit
+$ sudo systemctl start docker-kit
 ```
-10. For correct work of web server set necessary permissions via execute the `sudo chown -R www-data:www-data /srv/www` command. Use this directory for your projects 🍾
 
-> **Note:** To update Docker and Docker Compose you should delete both through the following commands:
-> ```bash
-> $ apt-get purge docker-ce
-> $ rm /usr/local/bin/docker-compose
-> ```
-> And then repeat the steps in point 5, specifying the desired version of Docker Compose. Also change `COMPOSE_API_VERSION` in the `.env` file according new API version of Docker (`$ docker version`).
+### Docker updating
+
+To update Docker Engine and Docker Compose you should delete both, and then install again specifying the desired version. Also change `DOCKER_API_VERSION` and `COMPOSE_API_VERSION` in the `.env` file according new API version of Docker Engine (`$ docker version`) and Docker Compose (`docker compose version`) respectively.
+
+### "Permission denied" error
+
+Use correct permissions for application directories. For PHP projects set permissions via execute the `sudo chown -R www-data:www-data /home/docker-kit/apps/php/` command. Or run the [docker-compose exec](https://docs.docker.com/compose/reference/exec/) command with the `--user` option.
