Dockerizing a Redis service (Engine)

Dockerizing a Redis service

Very simple, no frills, Redis service attached to a web application using a link.

Create a Docker container for Redis

Firstly, we create a Dockerfile for our new Redis image.

FROM        ubuntu:14.04
RUN         apt-get update && apt-get install -y redis-server
EXPOSE      6379
ENTRYPOINT  ["/usr/bin/redis-server"]

Next we build an image from our Dockerfile. Replace <your username> with your own user name.

$ docker build -t <your username>/redis .

Run the service

Use the image we’ve just created and name your container redis.

Running the service with -d runs the container in detached mode, leaving the container running in the background.

Importantly, we’re not exposing any ports on our containe
