Automate Vault backup

How to have the latest data every time

using watches and handlers in cosul we can monitor for changes in consul Based on vault doc data of secret enginese saved in logical path of kv So we should monitor consul kv kv/vault-ha/logical and the watch should execute and backup from the consul In this way we can have automated and updated backup.

Setup

Run setup.sh with the kv store of vault in consul. so, if kv store of vault in Consul is v1/vault-ha/original so it will be ./setup.sh

What it does?

Setup script will watch over data of vault secret engines' changes which is persistent in consul, whenever a change happen watch notify handler to trigger handler run consul snapshot cmd to save a snapshot locally. Note: for preventing lots of backup creation we will save just the last backup of the day called: /backup/backup-YYYY-mm-dd".back logs will be in /backup/vault-backup-logs.log

Docker way

docker build -t vault-backup . create image and you can add it to the consul server with three env:

CONSUL_HTTP_TOKEN= <token of consul with acl access>
KV_PATH=<key/vale path of vault in consul>
CONSUL_HTTP_ADDR=<http address of consul for connecting consul agent to>

Executing container with args:

docker run afrouzmash/vault-backup:v1 -it --name vault-backup -e CONSUL_HTTP_TOEKN=blahblah -e KV_APTH=vault-ha -e CONSUL_HTTP_ADDR=http://127.0.0.1:8500 -v /backup:/backup
docker exec -it vault-backup ./setup.sh

you can run docker image as an deployment or a sideCar

kubectl apply -f ./
