===== Часовой пояс в контейнере =====
Необходима установка tzdata. Dockerfile:
<code yaml>
FROM alpine
RUN apk add tzdata
CMD cp /usr/share/zoneinfo/Europe/Moscow /etc/localtime
</code>
https://gitlab.alpinelinux.org/alpine/aports/-/issues/5543

Альтернативный вариант - пробросить ''/etc/localtime'' с хоста. В docker-compose.yml:
<code yaml>
    volumes:
      - /etc/localtime:/etc/localtime:ro
</code>
===== cron =====
<code bash>
test -d /etc/periodic/daily9am || mkdir /etc/periodic/daily9am ; \
grep -q daily9am /etc/crontabs/root || echo -e "0\t9\t*\t*\t*\trun-parts /etc/periodic/daily9am" >> /etc/crontabs/root ; \
echo "#!/bin/sh" > /etc/periodic/daily9am/birthdays ; \
echo 'wget -O - -q "https://bva.dyndns.info/webtrees/reminder-cron/run?key=secretKeyHere"' >> /etc/periodic/daily9am/birthdays ; \
chmod a+x /etc/periodic/daily9am/birthdays ; \
