My take on a Borgbackup Server as a Docker container to faciliate the backing up of remote machines using Borgbackup
FROM alpine:latest
MAINTAINER b3vis
#Install Borg & SSH
RUN apk add openssh sshfs borgbackup supervisor --no-cache --repository https://dl-3.alpinelinux.org/alpine/edge/testing/
RUN adduser -D -u 1000 borg && \
ssh-keygen -A && \
mkdir /backups && \
chown borg.borg /backups && \
sed -i \
-e 's/^#PasswordAuthentication yes$/PasswordAuthentication no/g' \
-e 's/^PermitRootLogin without-password$/PermitRootLogin no/g' \
/etc/ssh/sshd_config
COPY supervisord.conf /etc/supervisord.conf
RUN passwd -u borg
EXPOSE 22
CMD ["/usr/bin/supervisord"]
I personally like to split my ssh keys out of the main container to make updates and management easier. To achieve this I create a persistent storage container;
docker run -d -v /home/borg/.ssh --name borg-keys-storage busybox:latest
- Container Creation:
docker create \
--name=borg-server \
--restart=always \
--volumes-from borg-keys-storage \
-v path/to/backups:/backups \
-p 2022:22 \
b3vis/borg-server
After creating the container you will need to start the container add your own public keys.
