istepanov/pg_dump

Docker image with pg_dump running as a cron task

Usage

Attach a target postgres container to this container and mount a volume to container's /dump folder. Backups will appear in this volume. Optionally set up cron job schedule (default is 0 1 * * * - runs every day at 1:00 am).

docker run -d \
    -v /path/to/target/folder:/dump \   # where to put db dumps
    -e 'CRON_SCHEDULE=0 1 * * *' \      # cron job schedule
    -e PGUSER=postgres \
    -e PGPASSWORD=mysecretpassword \
    --link my-postgres-container:db \   # linked container with running mongo
    istepanov/pg_dump dump-cron

Run backup once without cron job, use "mybackup" as backup file prefix, shell will ask for password:

docker run -ti --rm \
    -v /path/to/target/folder:/dump \   # where to put db dumps
    -e PREFIX=mybackup \
    --link my-postgres-container:db \   # linked container with running mongo
    istepanov/pg_dump dump
