Subject Re: [PROPOSAL] Create and provide karaf-boot plugin
Date Tue, 28 Apr 2015 11:51:04 GMT

I am looking forward to whatever it is that you produce. I enjoy karaf
and am sure as time goes on the tools will improve and I will get a
better at the understanding of them. I would love to learn more about
profiles as well. Are profiles complete for what is getting released in
the 4.0 version.

custom distributions i.e Modify the org.ops4j.pax.web.cfg to use port 8080 on startup Add
external jars to the lib directory. or is it just going to be an additional option for how
to deploy features. I am sorry if I am not on the right track. On 2015-04-27 15:53, Jean-Baptiste

a dependency. Imagine, that in your project pom.xml, you have: <parent> <groupId>org.apache.karaf.boot</groupId>
<artifactId>karaf-boot-starter-parent</artifactId> <version>4.0.0-SNAPSHOT</version>
</parent> The parent contains all plugins and dependencies set, especially the Karaf
standard distribution. Later in your pom.xml, you have: <build> <plugins> <plugin>
<groupId>org.apache.karaf.boot</groupId> <artifactId>karaf-boot-maven-plugin</artifactId>
</plugin> </plugins> </build> In your project, you just need a class describing
your Karaf bootstrapping: @KarafBootApplication @WithShell @profiles({"a","b","c"}) @featuresBoot({"f1","f2"})
public class MyContainer implements KarafBootstrapper { @Override public void run() { // setup
your Karaf bootstrapping } } The user can add "boot features" to customize the container:
<dependency> <groupId>org.apache.karaf.boot</groupId> <artifactId>org.apache.karaf.boot.webcontainer</artifactId>
</dependency> for instance it will automatically add Pax Web war feature in featuresBoot
(no need to use @featuresBoot). The purpose is to (depending of the goal used by the user):
1/ be able to run container+application easily 2/ package a custom distribution, ready to
go ("key turn") including applications Again, the approach is, from the native user codebase,
be able to bootstrap a container embedding the user applications. This container can be started
directly from the project, and provide an artifact ready to deploy (on docker, or whatever).
The artifact is actually a custom
karaf distribution. I hope it's clearer. Again, it's just an idea, but IMHO, it will give
a new dimension to Karaf: it will turn Karaf as a modern polymorphic container. The users
can still use Karaf "standalone" where they do the provisioning, or they can use Karaf "boot"
as basis for key turn application container. Regards JB On 04/27/2015 07:57 PM, Guillaume

all, On a local branch, I worked on some new goals for the karaf-maven-plugin, especially:
karaf:run to easily bootstrap and start a Karaf instance +1 karaf:deploy to upload (scp) the
project artifact (or a given artifact) in the deploy folder or the system folder (respecting
the maven structure) +1 we could also add sftp and http/https upload, with the help of the
maven http servlet i've added in 4.x karaf:client to connect to a running Karaf instance and
execute commands +1, i suppose we'd need interactive and scripted, like the bin/client
script, right ? I would like to add a new plugin (more than a new goal): karaf-boot-maven-plugin
with the boot goal. The purpose is easily: 1/ in the end user code module, build a karaf custom
distribution including karaf standard distribution and the end user built application 2/ be
able to easily include test with pax-exam 3/ provide a ready to run artifact 4/ provide a
way to specify profiles or features to include in the distribution It's just an idea for now.
The purpose is to provide a ready to run Karaf container like users does with spring-boot.
So it would create the distribution, same as the install-kars / assembly goal, then use the
karaf:run goal ? The only step than the assembly / run / archive goals can't do is the tests,
but I'm not completely sure to understand this part... It looks more like an archetype than
a plugin to me ? Or do I miss something ? Thoughts ? Regards JB -- Jean-Baptiste Onofré jbonofre@apache.org
