Working with an All-In-One project

Before you continue make sure that you have read and completed the tasks in the Getting started tutorial to generate an All-In-One (AIO) project, which means selecting the org.alfresco.maven.archetype:alfresco-allinone-archetype Maven archetype when generating the project. The following information assumes that the AIO project was generated with the name my-all-in-one-project.

Introduction

An AIO SDK project is used to build extensions for both Alfresco Content Services (ACS) Repository and Alfresco Share UI. The runtime environment for ACS is Docker so not only is this project building the source code for your extensions but also the custom Docker images for the Alfresco Repository and Alfresco Share. The custom Docker images includes the JARs, or AMPs, with your extension code.

Looking into the generated AIO parent project we can see that we got a Docker Compose file (my-all-in-one-project/docker/docker-compose.yml) that will be used to build custom Docker images and run the project, one sub-project called my-all-in-one-project-platform that will be used to build Repository customizations, and one sub-project called my-all-in-one-project-share that can be used to build Alfresco Share UI customizations.

There are also the my-all-in-one-project-platform-docker and my-all-in-one-project-share-docker projects that are used to assemble (aggregate) all the Repository and Share extensions (there are usually more than one of each in a bigger project) and then build the custom Docker images with the extension(s) applied.

The Repository and Share extensions that are aggregated can either be extensions that you develop locally or extensions that are available in a Maven repository somewhere.

Configuration properties

There are a number of properties that we can customise when we run the Alfresco SDK project. These configuration properties are defined in the my-all-in-one-project/pom.xml project file.

The following table explains some of these properties:

Name Type Default value Description
alfresco.platform.version string 6.1.2-ga The version of the ACS Repository (i.e. alfresco.war) that the Repository Extension should be applied to. This also specifies the version of the ACS Repository Docker Image that the custom built Repository image should be based on. See my-all-in-one-project-platform-docker/src/main/docker/Dockerfile
alfresco.share.version string 6.1.0-RC3 The version of Alfresco Share (i.e. share.war) that the Share Extension should be applied to. This also specifies the version of the Alfresco Share Docker Image that the custom built Share image should be based on. See my-all-in-one-project-share-docker/src/main/docker/Dockerfile
docker.acs.image string alfresco/alfresco-content-repository-community The name of the ACS Repository Docker image in Docker Hub. This changes if you switch to Enterprise Edition.
docker.share.image string alfresco/alfresco-share The name of the Alfresco Share Docker image in Docker Hub. This changes if you switch to Enterprise Edition.
share.port number 8180 The external port (i.e. outside container) for the Alfresco Share webapp.
share.debug.port number 9898 The external port (i.e. outside container) for Alfresco Share remote debugging.
acs.host string my-all-in-one-project-acs This is the name (host) that the ACS Repository is available at. This maps to the service name for the ACS Repository in the Docker Compose file my-all-in-one-project/docker/docker-compose.yml. The name is only useful for communication between containers on the default Docker network that is created.
acs.port number 8080 The external port (i.e. outside container) for the ACS Repository.
acs.debug.port number 8888 The external port (i.e. outside container) for ACS Repository remote debugging.
postgres.port number 5555 The external port (i.e. outside container) for PostgreSQL database.

When you first start out you don't need to change any of these properties, just use the defaults and try it out.

Building and running the project

The first thing you need to do before you can run anything is to build the custom ACS Docker images with the custom extensions. We can build images and extensions at the same time as we start (run) the project by using the ./run.sh build_start script (on Windows use the run.bat build_start script instead).

Note that if you have another Alfresco SDK project running, then you need to stop it first. Also, make sure that the following ports are free: 8180 (Share), 8080 (Alfresco Repo), 9898 (Share Debug), 8888 (Alfresco Repo Debug), 5555 (Postgres). If you want to change the ports see the properties section of my-all-in-one-project/pom.xml. This project file also contains the versions of Alfresco Repository and Alfresco Share that will be used.

The ./run.sh build_start script will do the following:

  • Stop anything running already with this project's Docker Compose file: my-all-in-one-project/docker/docker-compose.yml
  • Build the Repository and Share Extension JARs so we are sure to get the latest changes
  • Assemble/Aggregate all Repository extension JARs into the my-all-in-one-project/my-all-in-one-project-platform-docker/target/extensions directory
  • Assemble/Aggregate all Share extension JARs into the my-all-in-one-project/my-all-in-one-project-share-docker/target/extensions directory
  • Create Docker Volumes for Repository (alf_data), Search index, and Database so data is persisted outside the containers
  • Run the project via the Docker Compose file and instruct Docker Compose to build the custom Docker images first
  • Tail the logs of all containers

This will build the following two Docker images:

$ docker image ls|more

The different web applications should now be accessible:

Trying out the sample code

The AIO project has some sample extension code that you can try out. There is a one Repository extension and one Share extension that you can test to make sure the extension JARs have been applied properly.

The Repository extension is a Web Script that can be called with the following URL: http://localhost:8080/alfresco/service/sample/helloworld. The source code for the Web Script is located here: my-all-in-one-project/my-all-in-one-project-platform/src/main/resources/alfresco/extension/templates/webscripts/alfresco/tutorials and here: my-all-in-one-project/my-all-in-one-project-platform/src/main/java/ com/example/platformsample/HelloWorldWebScript.java.

The Share extension is a custom Aikau page with a custom widget, you reach it with the following URL: http://localhost:8180/share/page/hdp/ws/simple-page. The source code for the Page and Widget is located here: my-all-in-one-project/my-all-in-one-project-share/src/main/resources/alfresco/web-extension/site-webscripts/com/example/pages and here: my-all-in-one-project/my-all-in-one-project-share/src/main/resources/META-INF/resources/my-all-in-one-project-share/js/tutorials/widgets.

Looking inside the containers

Sometimes it's good to be able to look at what has actually been deployed in the containers. For example, how do I access the Repository container and list the custom Repository extension JARs that have been deployed?

You can do that as follows:

First Ctrl-C out of the log tailing:

my-all-in-one-project-acs_1       | 27-Mar-2019 07:26:23.893 INFO [main] org.apache.coyote.AbstractProtocol.start Starting ProtocolHandler ["http-nio-8080"]

my-all-in-one-project-acs_1       |  2019-03-27 07:26:24,304  INFO  [management.subsystems.ChildApplicationContextFactory] [http-nio-8080-exec-3] Starting 'Search' subsystem, ID: [Search, managed, solr6]

^CERROR: Aborting.
my-all-in-one-project mbergljung$ 

Then check the name of the ACS Repository container:

$ docker container ls
CONTAINER ID        IMAGE                                                         COMMAND                  CREATED             STATUS              PORTS                                                      NAMES

1f197e52b4f2        alfresco/alfresco-search-services:1.2.0                       "/bin/sh -c '$DIST_D…"   5 minutes ago       Up 5 minutes        0.0.0.0:8983->8983/tcp                                     docker_my-all-in-one-project-ass_1
4eff0cc9cc25        alfresco-share-my-all-in-one-project:development              "/usr/local/tomcat/s…"   5 minutes ago       Up 5 minutes        8000/tcp, 0.0.0.0:8180->8080/tcp, 0.0.0.0:9898->8888/tcp   docker_my-all-in-one-project-share_1
a7854ff16d72        postgres:9.6                                                  "docker-entrypoint.s…"   5 minutes ago       Up 5 minutes        0.0.0.0:5555->5432/tcp                                     docker_my-all-in-one-project-postgres_1

Then open up a shell into the ACS Repository container:

my-all-in-one-project mbergljung$ docker exec -it docker_my-all-in-one-project-acs_1 /bin/bash
[root@733867a70117 tomcat]# pwd
/usr/local/tomcat
[root@733867a70117 tomcat]# ls -l webapps/alfresco/WEB-INF/lib | grep "my-all"
-rw-r--r-- 1 root root    17220 Mar 27 07:24 my-all-in-one-project-platform-1.0-SNAPSHOT.jar
[root@733867a70117 tomcat]# exit
exit

Updating extension code

So now you probably want to write some new code, or update the existing code, and see how that works with the containers running. What do you need to do, restart etc. First just update the code. For example, let's update the Repository Web Script to return a different message. Open up the my-all-in-one-project/my-all-in-one-project-platform/src/main/resources/alfresco/extension/templates/webscripts/alfresco/tutorials/helloworld.get.html.ftl file and change it to look as follows:

Message: '${fromJS}' '${fromJava}' UPDATED!

To get this code update deployed we just have to run the following command in another console then where we are tailing the logs, and stand in the directory where the run.sh script is located:

my-all-in-one-project mbergljung$ ./run.sh reload_acs

What this will do is the following:

  • Kill the my-all-in-one-project-acs container
  • Remove the killed (stopped) my-all-in-one-project-acs container, so a new Docker image can be created with development tag
  • Build the Repository extension JAR: my-all-in-one-project/my-all-in-one-project-platform
  • Copy the newly built Repository extension JAR over to the my-all-in-one-project/my-all-in-one-project-platform-docker/target/extensions where it will be picked up when the new Docker image is built.
  • Build a new alfresco-content-services-my-all-in-one-project:development image
  • Start up the my-all-in-one-project-acs container based on new image

You will be left with the console tailing the logs, but you can Ctrl-C out of this as you are already tailing the logs in the initial console where we started things up.

You can now check if the change took effect by accessing the http://localhost:8080/alfresco/service/sample/helloworld Web Script.

Stopping the project

To stop the solution you need to first Ctrl-C out of the log tailing. This does not stop the containers as they run in daemon mode in the background. Check this by executing the following command that lists running containers:

$ docker container ls
CONTAINER ID        IMAGE                                                         COMMAND                  CREATED             STATUS              PORTS                                                      NAMES
49015432f1b2        alfresco-content-services-my-all-in-one-project:development   "catalina.sh run -se…"   20 minutes ago      Up 20 minutes       0.0.0.0:8080->8080/tcp, 0.0.0.0:8888->8888/tcp             docker_my-all-in-one-project-acs_1
edb9ea129a5d        postgres:9.6                                                  "docker-entrypoint.s…"   20 minutes ago      Up 20 minutes       0.0.0.0:5555->5432/tcp                                     docker_my-all-in-one-project-postgres_1
6992d183986f        alfresco/alfresco-search-services:1.2.0                       "/bin/sh -c '$DIST_D…"   20 minutes ago      Up 20 minutes       0.0.0.0:8983->8983/tcp                                     docker_my-all-in-one-project-ass_1
107d00733efd        alfresco-share-my-all-in-one-project:development              "/usr/local/tomcat/s…"   20 minutes ago      Up 20 minutes       8000/tcp, 0.0.0.0:8180->8080/tcp, 0.0.0.0:9898->8888/tcp   docker_my-all-in-one-project-share_1

Now, standing in the directory where the run.sh script is located execute the following command to stop and remove the containers:

my-all-in-one-project mbergljung$ ./run.sh stop
Stopping docker_my-all-in-one-project-acs_1      ... done
Stopping docker_my-all-in-one-project-postgres_1 ... done

Removing docker_my-all-in-one-project-ass_1      ... done
Removing docker_my-all-in-one-project-share_1    ... done
Removing network docker_default
You can’t perform that action at this time.
