docker-volume-replicator (2.0)

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...

Mount volumes onto the paths /volume-a and /volume-b
Set environment variable REPLICATE_DIRECTION (to either AtoB or BtoA)
Set environment variable REPLICATE_DELETE to anything other than yes to avoid wiping the destination

In 2.0 you can use S3 as a destination or source. To do this you must set VOLUME_A_IS_S3 (where '/volume-a' is expected to be the S3 volume). See the docker-entrypoint.sh for details of these and other related environment variables.

Building the image

Just run docker...

$ docker-compose build

And run typically with something like: -

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