Docker Image Run Inbucket in a container
Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries – anything you can install on a server. This guarantees that it will always run the same, regardless of the environment it is running in.
docker run -p 9000:10080 -p 2500:10025 jhillyerd/inbucket
Then point your browser at localhost:9000
