# Это заготовка для нормального файла
Для настройки Dev-окружения нужно склонировать проект в удобное место,
за тем сделать символьную ссылку в свой GOPATH:
```sh
# Выполнять, находясь внутри директории репозитория
mkdir -p $GOPATH/src/elyby
ln -s $PWD $GOPATH/src/elyby/minecraft-skinsystem
```
Или можно склонировать репозиторий сразу в нужную локацию:
```sh
git clone git@bitbucket.org:elyby/minecraft-skinsystem.git $GOPATH/src/elyby/minecraft-skinsystem
```
Поднять репозиторий можно командой:
```sh
docker-compose up -d
```
Рекомендуемый файл `docker-compose.override.yml` для dev-окружения:
```sh
version: '2'
services:
app:
volumes:
- ./:/go/src/app
command: ["go", "run", "minecraft-skinsystem.go"]
```
В таком случае, для перезапуска контейнера (при условии, что не появляется
новых зависимостей) будет достаточно выполнить только одну команду:
```sh
docker-compose restart app
```
Если нужно пересобрать весь контейнер, то выполняем следующее:
```
docker-compose stop app # Останавливаем конейтнер, если он ещё работает
docker-compose rm -f app # Удаляем конейтнер
docker-compose build app # Запускаем билд по новой
docker-compose up -d app # Поднимаем свежесобранный контейнер обратно
```
