OpenShift_019：使用 Dockerfile 部署 .war 到 JBoss EAP 7

环境：OCP 3.3

本文利用已有的 JBoss EAP 7 image 作为 base image，编写 Dockerfile 把 .war 文件拷贝到 EAP 部署目录下。

1. mkdir example

2. cd example

3. vim Dockerfile
FROM registry.example.com:5000/jboss-eap-7/eap70-openshift:latest
#EXPOSE 8080 8888
COPY example.war $JBOSS_HOME/standalone/deployments/ROOT.war

4. 复制 example.war 到 example 目录下

5. oc login -u admin -p admin

6. oc new-project example

7. cd .. 退到 example 上一级目录

8. oc new-app example --name=example --insecure-registry=true
输出如下：
--> Found Docker image 07ebd7e (5 months old) from registry.example.com:5000 for "registry.example.com:5000/jboss-eap-7/eap70-openshift:latest"

    * An image stream will be created as "eap70-openshift:latest" that will track the source image
    * A Docker build using binary input will be created
      * The resulting image will be pushed to image stream "example:latest"
      * Use 'start-build --from-dir=DIR|--from-repo=DIR|--from-file=FILE' to trigger a new build
      * WARNING: a binary build was created, you must specify one of --from-dir|--from-file|--from-repo when starting builds
    * This image will be deployed in deployment config "example"
    * Ports 8080/tcp, 8443/tcp, 8778/tcp will be load balanced by service "example"
      * Other containers can access this service through the hostname "example"
