# docker-postgres-backup

this is forked from https://github.com/jmcarbo/docker-postgres-backup

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

## Usage:

    docker run -d \

        --env POSTGRES_HOST=mysql.host \

        --env POSTGRES_PORT=27017 \

        --env POSTGRES_USER=admin \

        --env POSTGRES_PASSWORD=password \

        --volume host.folder:/backup

        nexus.rancher.emundo.local/emundo-ci/postgres-backup

Moreover, if you link `nexus.rancher.emundo.local/emundo-ci/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 nexus.rancher.emundo.local/emundo-ci/postgres-backup

## Parameters

    POSTGRES_HOST      the host/ip of your postgres database

    POSTGRES_PORT      the port number of your postgres database

    POSTGRES_USER      the username of your postgres database

    POSTGRES_PASSWORD      the password of your postgres database

    POSTGRES_DB        the database name to dump. Default: `--all-databases`

    EXTRA_OPTS      the extra options to pass to pg_dump command

    CRON_TIME       the interval of cron job to run pg_dump. `0 0 * * *` by default, which is every day at 00:00

    MAX_BACKUPS     the number of backups to keep. When reaching the limit, the old backup will be discarded. No limit by default

    INIT_BACKUP     if set, create a backup when the container starts

    INIT_RESTORE_LATEST if set, restores latest backup

## Restore from a backup
