## Select for update skip locked with Spring Boot and Repositories
  @Lock(LockModeType.PESSIMISTIC_WRITE)
  @QueryHints({
    @QueryHint(name = "javax.persistence.lock.timeout", value =  LockOptions.SKIP_LOCKED + "") // LockOptions.SKIP_LOCKED == -2
  })
  List<SomeEntity> findByStatus(SomeEntityStatus status);

## docker-compose.yml

version: '2'
services:
  zookeeper:
    image: confluentinc/cp-zookeeper:3.3.0
    hostname: zookeeper
    ports:
      - "2181:2181"
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181

## Деплой spring boot приложения в debian подобной среде
# Путь /etc/systemd/system/myservice.service
[Unit]
Description=Desciption about my service
After=syslog.target network.target

[Service]
Type=forking

ExecStart=/opt/myservice/startup.sh

## Грепнуть часть логов из докер контейнера
sudo docker logs <container_name>  2>&1 | grep "подстрока для поиска" -A 100 -B 100

## Лучшие практики
# Архитектура

1. Паттерны микросервисов https://microservices.io/patterns/index.html

## docker-minio
docker run -d --name minio -p 9000:9000 -e "MINIO_ACCESS_KEY=admin" -e "MINIO_SECRET_KEY=adminadmin" minio/minio server /data

## git repush tag
1. While still on any branch

git tag -d v1.1

2. Create the tag again: This will "move" the tag to point to your latest commit on that branch

git tag v1.1

3. Delete the tag on remote
