amazon/dynamodb-local Error: "Invalid directory for database creation"

Question

While attempting to run this docker command `docker run -p 8001:8001 amazon/dynamodb-local -jar DynamoDBLocal.jar -sharedDb -dbPath $DATA_DIRECTORY -cors http://localhost:5173,http://localhost:3000`

I receive a **Invalid directory for database creation.** error. I run the command above from a bash script:
```bash
DATA_DIRECTORY=$(realpath data)
docker run -p 8001:8001 amazon/dynamodb-local -jar DynamoDBLocal.jar -sharedDb -dbPath $DATA_DIRECTORY -cors http://localhost:5173,http://localhost:3000
```
When I inspect the docker container I can see that the args passed are correct and the folder does exist. Not sure what I am doing wrong here.

Answer

The `-dbPath` specifies the path in the container.
Therefore, if you want to create it in a folder on your computer, you must share it with the container using the `-v' option.

For example, you can run the following.

```
docker run -p 8001:8001 -v $DATA_DIRECTORY:/home/dynamodblocal amazon/dynamodb-local -jar DynamoDBLocal.jar -sharedDb -dbPath . -cors http://localhost:5173,http://localhost:3000
```
