ratpack-docker-example

An example of how to package a Ratpack application as a Docker container.

Running the Example

1. Package the application as a Docker container by running the following Gradle command:

    $ ./gradlew buildImage
   

   Once the build completes you will see Docker Image ID that was created in the console:

   > Task :buildImage
   Created image with ID '02e353fa9cc5'.
   

2. Start the newly created Docker container with the following command:

    $ docker run -p5050:5050 -d {image id}
   

3. Test that the service is running in the container by executing the following command:

    $ curl -v http://localhost:5050/example
   

   If successful you will receive an HTTP 200 similar to the following:

    *   Trying ::1...
    * TCP_NODELAY set
    * Connected to localhost (::1) port 5050 (#0)
    > GET /example HTTP/1.1
    > Host: localhost:5050
    > User-Agent: curl/7.54.0
    > Accept: */*
    >
    < HTTP/1.1 200 OK
    < content-type: text/plain;charset=UTF-8
    < content-length: 17
    <
    * Connection #0 to host localhost left intact
    This thing works!
