Mini-projet de Systèmes d'informations (3e année, janvier 2015)

Le container inclut un Glassfish faisant tourner un war (WeddingSiteApp.war). Le site comprend:

• single site avec Angularjs pour faire des cadeaux de mariage et laisser un commentaire dans le guest book
• single admin page pour gérer les cadeaux

Le tout avec un service REST et JPA côté serveur.

Pour utiliser le container

Lancer le container:

docker run  \
     -v path/to/war/folder:/opt/oracle/glassfish4/glassfish/domains/domain1/autodeploy/  \
     -v path/to/datasources:/opt/oracle/glassfish4/glassfish/databases/ \
    -p 8080:8080 -p 1527:1527 -p 4848:4848 \
     derlin/wed-live:latest

Ajouter -d pour le lancer en daemon.

Pour ensuite ouvrir un shell:

docker ps
docker exec -ti <container id> bash

pour l'autodeploy avec netbeans

In project.properties file must add a reference for your end folder:

war.custom.dir=/path/to/war/folder/

Then, in your build.xml file should add this chunk of code:

<target name=“-post-dist”> 
    <echo message=“Copy .war file to my custom folder”/> 
    <copy file=“${dist.war}” todir=“${war.custom.dir}” /> 
</target>

Note: don't use the default dist folder, since it is removed/recreated on each build !

using a data-container for the databases

Create the container

First, create and run a data only container. For this, either use a Dockerfile or simply use a run command. With a dockerfile:

# Dockerfile
FROM busybox
VOLUME /opt/oracle/glassfish4/glassfish/databases/
CMD /bin/sh

and then:

docker build -t user/db_store .

With a run command:

docker run -ti -v /opt/oracle/glassfish4/glassfish/databases --name db_store busybox /bin/sh

Use the container

Build the wed-live image, commit, and relaunch it with:

docker run \     
    --volumes-from db_store \
    -p 8080:8080 -p 1527:1527 -p 4848:4848 \
    derlin/test

Backup and restore databases

Backup:

docker run --volumes-from db_store -v $(pwd):/backup busybox \
    cd /opt/oracle/glassfish4/glassfish/databases && tar czvf /backup/backup.tar.gz .

Restore it in a new container:

docker run -ti -v /opt/oracle/glassfish4/glassfish/databases --name db_store2 busybox /bin/sh
docker run --volumes-from db_store2 -v $(pwd):/backup busybox \
    cd /opt/oracle/glassfish4/glassfish/databases && tar xzvf /backup/backup.tar.gz
