This image runs pg_dump to backup data using cronjob to folder /backup


docker run -d \
    --env \
    --env PG_PORT=27017 \
    --env PG_USER=admin \
    --env PG_PASSWORD=password \
    --volume host.folder:/backup

Moreover, if you link jmcarbo/docker-postgres-backup to a postgres container (e.g. tutum/mysql) with an alias named pg, this image will try to auto load the host, port, user, pass if possible.

docker run -d -p 27017:27017 -p 28017:28017 -e PG_PASS="mypass" --name pg postgres
docker run -d --link pg:pg -v host.folder:/backup jmcarbo/docker-postgres-backup
