IBM Containers running Spring Boot Applications with IBM Bluemix

There is now a new command line plugin for IBM containers on Bluemix so you can push and run docker images using CF CLI itself. The steps below show you how to set this up and I use a basic spring boot application as a docker image to test this out.

Steps

Take a note of the docker local host IP. In this example it was as follows, as I test my docker image on my laptop prior to pushing it to Bluemix.

-> docker is configured to use the default machine with IP 192.168.99.100

1. Install the latest CF command line, I used the following version.

pasapicella@pas-macbook-pro:~/bluemix_apps/CONTAINERS/ibm-containers/gs-rest-service/complete$ cf --version
cf version 6.14.0+2654a47-2015-11-18


https://github.com/cloudfoundry/cli

2. Install IBM Containers Cloud Foundry plug-in

pasapicella@pas-macbook-pro:~$ cf install-plugin https://static-ice.ng.bluemix.net/ibm-containers-mac

**Attention: Plugins are binaries written by potentially untrusted authors. Install and use plugins at your own risk.**

Do you want to install the plugin https://static-ice.ng.bluemix.net/ibm-containers-mac? (y or n)> y

Note: Default plugin directory as follows

$HOME/.cf/plugins


3. Login to IBM Containers

pasapicella@pas-macbook-pro:~/bluemix_apps/CONTAINERS$ cf ic login

OK

OK
Your container was authenticated with the IBM Containers registry.
Your private Bluemix repository is URL: registry.ng.bluemix.net/apples

You can choose from two ways to use the Docker CLI with IBM Containers:

Option 1: This option allows you to use "cf ic" for managing containers on IBM Containers while still using the Docker CLI directly to manage your local Docker host.
    Use this Cloud Foundry IBM Containers plug-in without affecting the local Docker environment:

    Example Usage:
    cf ic ps
    cf ic images

Option 2: Use the Docker CLI directly. In this shell, override the local Docker environment to connect to IBM Containers by setting these variables. Copy and paste the following commands:
    Note: Only Docker commands followed by (Docker) are supported with this option.

     export DOCKER_HOST=tcp://containers-api.ng.bluemix.net:8443
     export DOCKER_CERT_PATH=/Users/pasapicella/.ice/certs/containers-api.ng.bluemix.net/0bcbcada-bd11-4372-b416-955dff3078a1
     export DOCKER_TLS_VERIFY=1

    Example Usage:
    docker ps
    docker images
4. View docker images

pasapicella@pas-macbook-pro:~/bluemix_apps/CONTAINERS$ cf ic images

5. Clone application to run as docker image

$ git clone https://github.com/spring-guides/gs-rest-service.git

6. Create a file called Dockerfile as follows in the "complete" directory

pasapicella@pas-macbook-pro:~/bluemix_apps/CONTAINERS/ibm-containers/gs-rest-service/complete$ cat Dockerfile
FROM java:8
VOLUME /tmp
ADD target/gs-rest-service-0.1.0.jar app.jar
RUN bash -c 'touch /app.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]


7. Package the demo

$ mvn package

8. Build docker image

pasapicella@pas-macbook-pro:~/bluemix_apps/CONTAINERS/ibm-containers/gs-rest-service/complete$ docker build -t gs-rest-service .
