xld-petclinic-docker

A sample Java application that shows how to package war in a tomcat docker image and deploy them with 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/vpartington/.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)"

• run mvn clean package

To integrate with XL Deploy,

• start XL Deploy version 5.0 with the xld-docker-plugin defined here: https://github.com/vpartington/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
