xld-petclinic-docker

A sample application that shows how to package docker images and deploy them to a Docker Engine and a Kubenetes Cluster using XLDeploy.

Usage

• set the docker environment

export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.123:2376"
export DOCKER_CERT_PATH="/Users/bmoussaud/.docker/machine/machines/docker-machine-virtualbox-1"
export DOCKER_MACHINE_NAME="docker-machine-virtualbox-1"
# Run this command to configure your shell:
# eval "$(docker-machine env docker-machine-virtualbox-1)"

or

eval $(minikube docker-env)

• run mvn clean package to build the applications and the associated images

To push the images to Docker registries

• local trusted registry (default url is 192.168.99.100:5000)
• docker.hub (edit the ~/.m2/settings.xml)

   <server>
        <id>docker-hub</id>
        <username>bmoussaud</username>
        <password>XXXXXXXX</password>
        <configuration>
          <email>bmoussaud@xebialabs.com</email>
        </configuration>
   </server>
  

To integrate with XL Deploy,

• start XL Deploy version with the default bundled xld-docker-plugin
• run mvn clean install. This command pushthe images in the registry using a timestamp for version and import the XL Deploy DAR file in XL Deploy

The XL Deploy manifest file for the application (Docker):
