How to create a custom Redis image

This is a step-by-step guide to creating a custom Redis image in case of fine tuned Redis configurations/customizations/disaster recovery.

Prerequisites

Create a new directory for your project.
```
mkdir redis-testing
cd redis-testing
```
Create a new Dockerfile in the root of your project.
```
cd > Dockerfile
```

Run a container with the redis/redis-stack image.

docker run -it --rm --name redis-stack -p 6379:6379 -p 8001:8001 redis/redis-stack:latest

Inspect the container.
```
docker inspect --name redis-stack
```
Take note of the ENV and the CMD. We will need these later.
Stop the container, then export the container.
```
docker stop redis-stack
docker export --name redis-stack redis-stack-container.tar
```
This will create a file called redis-stack-container.tar in the current directory.
Add the location of the redis-stack-container.tar file to the Dockerfile with COPY to copy it into the container (target the container root directory).
Build the image.
```
docker build -t redis-testing .
```

Run the image.

docker run -it --rm --name redis-testing -p 6379:6379 -p 8001:8001 redis-testing
