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
