Zdravím, je tu někdo kdo rozumí Dockeru a jeho backupům? Chtěl jsem si před updatem aplikace vytvořit zálohu .tar balíček. Apka je nainstalovaná pomocí docker-compose. V Docker-compose je toto:

/usr/local/plausible # cat docker-compose.yml 
version: "3.3"
services:
  mail:
    image: bytemark/smtp
    restart: always

  plausible_db:
    image: postgres:12
    restart: always
    volumes:
      - db-data:/var/lib/postgresql/data
    environment:
      - POSTGRES_PASSWORD=postgres

  plausible_events_db:
    image: yandex/clickhouse-server:21.3.2.5
    restart: always
    volumes:
      - event-data:/var/lib/clickhouse
      - ./clickhouse/clickhouse-config.xml:/etc/clickhouse-server/config.d/logging.xml:ro
      - ./clickhouse/clickhouse-user-config.xml:/etc/clickhouse-server/users.d/logging.xml:ro
    ulimits:
      nofile:
        soft: 262144
        hard: 262144
    build: .

  plausible:
    image: plausibe_from_back:latest
    restart: always
    command: sh -c "sleep 10 && /entrypoint.sh db createdb && /entrypoint.sh db migrate && /entrypoint.sh db init-admin && /entrypoint.sh run"
    depends_on:
      - plausible_db
      - plausible_events_db
      - mail
    ports:
      - 8000:8000
    env_file:
      - plausible-conf.env

volumes:
  db-data:

Abych to zabackupoval, dávám: "docker export" pro vytvořeni tar balíčku s image (backup), a importnu ho:

docker export 521652a81c22 > /root/backup_docker/yandex_`date -I`.tar
docker import - yandex_from_back < /root/backup_docker/yandex_2023-07-24.tar

V docker-compose file zaměním image, chci vyzkoušet backupovanou image:

#Puvodni:
  plausible_events_db:
    image: yandex/clickhouse-server:21.3.2.5

#Zmenim na:

  plausible_events_db:
    image: yandex_from_back:latest

viz:
# docker images
REPOSITORY                     TAG               IMAGE ID       CREATED             SIZE
yandex_from_back               latest            c23ef7bb8f72   About an hour ago   398MB

A pustím, docker-compose up:

Tady bych se chtěl zeptat, jestli v postupu zálohování postupuji správně, nebo jak tedy kontejner správně odzálohovat? Děkuji za radu.
