I started using Redis 6.0 in docker container recently and faced with the following issue, suddenly: I see in logs that Redis container started to try writing to /var/spool/cron directory.
It is the second time I face the problem, first time It happened tonight (in several hours after launch). If I restart container, everything is fine again.
I have found link which stated that it happens so, because Redis container was hacked: The link
Is it true and how can I solve the issue?
My Dockerfile:
FROM redis:6.0-alpine
WORKDIR /usr/src/app
RUN apk add --no-cache tzdata
ENV TZ=Europe/Moscow
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
COPY redis.conf /usr/local/etc/redis/redis.conf
CMD [ "redis-server", "/usr/local/etc/redis/redis.conf" ]
RUN chmod 0755 /usr/src/app/
RUN chmod 0755 /etc/crontabs/
RUN chmod 0755 /data/
Redis Config key points:
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::1
protected-mode no # I thought that if I have user protected-mode works by default
port 6379
dbfilename dump.rdb
dir ./
user someusername allcommands allkeys on >somelongpassword
I run docker conatainer the following way:
docker run -p 6379:6379 -v myvol:/usr/src/app --name redis -d --network mynet redis
I attached print screen of my terminal window.
