### Dockerfile VOLUME ###

Định nghĩa VOLUME trong Dockerfile sẽ:
* Expose folder/directory được tạo bởi container ra đường dẫn trên host: `/var/lib/docker/volumes/[container_id]/_data/`
Note: `_data` được gọi là *"mount point"*

Run container với lệnh: `docker run --rm image`

Khi container được run, ta có thể check volume được tạo bởi container bằng câu lệnh: `docker volume ls`
Khi container exited, volume sẽ mất do ta định nghĩa cờ `--rm` ở câu lệnh `docker run`, do đó container và volume của nó sẽ được remove hoàn toàn.

In `scripts/` sub-directory are custom scripts called by crontab, e.g. `arangodb-snapshot.sh` for backingup arango database daily:

```shell
#!/bin/bash
set -e

BASE_DUMP_DIR=/var/lib/arangodb3/backups
CUR_DUMP_DIR="mydb-dump-`date '+%Y%m%d%H%M%S'`"
TAR_BALL="${CUR_DUMP_DIR}.tgz"

mkdir -p "$BASE_DUMP_DIR"
cd "$BASE_DUMP_DIR"

docker exec my-arango arangodump \
    --server.database=mydb \
    --server.username='root' --server.password='' \
    --output-directory="${BASE_DUMP_DIR}/${CUR_DUMP_DIR}"

tar -cvzf "$TAR_BALL" "$CUR_DUMP_DIR"

## Send to cloud-storage

## Notify success

```

Run:

```shell
docker run -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/amidala/arangodb3:/var/lib/arangodb3 cron
```
