informaticsmatters/volume-replicator repository overview

⁠docker-volume-replicator

A simple container image that expects two volume mounts "/volume-a" and "/volume-b" where data is replicated (using rsync) from one to the other based on an environment variable whose value is either AtoB or BtoA.

When running the image...

1. Mount volumes onto the paths /volume-a and /volume-b
2. Set environment variable REPLICATE_DIRECTION
3. Set environment variable REPLICATE_DELETE to anything other than yes to avoid wiping the destination

⁠Building the image

Just run docker..

$ docker build . -t informaticsmatters/volume-replicator:latest

And run typically with something like: -

$ docker run --rm -e REPLICATE_DIRECTION=AtoB \
        -v $PWD/a:/volume-a \
        -v $PWD/b:/volume-b \ 
        informaticsmatters/volume-replicator:latest
