AAI Developer Environment Setup
================================
This guide will illustrate setting up an A&AI development environment in
Ubuntu 16.04.
For this exercise, I set up a new instance of Ubuntu in Virtualbox and
gave it 16G RAM, 200GB dynamically allocated storage, and 3 processors.
- install openjdk 8
..code:: bash
sudo apt install openjdk-8-jdk
- Install single node hadoop/titan
..code:: bash
wget http://s3.thinkaurelius.com/downloads/titan/titan-1.0.0-hadoop1.zip
unzip titan-1.0.0-hadoop1.zip
cd titan-1.0.0-hadoop1
sudo ./bin/titan.sh start
- Install haproxy
..code:: bash
sudo apt-get -y install haproxy
haproxy -v
HA-Proxy version 1.6.3 2015/12/25
Copyright 2000-2015 Willy Tarreau
willy@haproxy.org http://haproxy.org/
- Install this haproxy.cfg file in /etc/haproxy
`haproxy.cfg <https://wiki.onap.org/download/attachments/10782088/haproxy.cfg?version=2&modificationDate=1501018863000&api=v2>`__
..code:: bash
sudo cp aai.pem /etc/ssl/private/aai.pem
sudo chmod 640 /etc/ssl/private/aai.pem
sudo chown root:ssl-cert /etc/ssl/private/aai.pem
`aai.pem <https://wiki.onap.org/download/attachments/10782088/aai.pem?version=1&modificationDate=1501019585000&api=v2>`__
..code::bash
sudo mkdir /usr/local/etc/haproxy
- Add these hostnames to the loopback interface in /etc/hosts:
..code:: bash
127.0.0.1 localhost aai-traversal.api.simpledemo.openecomp.org aai-resouces.api.simpledemo.openecomp.org
- Restart haproxy
..code:: bash
sudo service haproxy restart
- Set up repos. First, follow the initial setup instructions in
`Setting Up Your Development Environment <https://wiki.onap.org/display/DW/Setting+Up+Your+Development+Environment>`__
..code:: bash
mkdir -p ~/LF/AAI
cd ~/LF/AAI
git clone ssh://<username>@gerrit.onap.org:29418/aai/aai-common
git clone ssh://<username>@gerrit.onap.org:29418/aai/traversal
git clone ssh://<username>@gerrit.onap.org:29418/aai/resources
git clone ssh://<username>@gerrit.onap.org:29418/aai/logging-service
- If you did not originally create a settings.xml file when setting
up the dev environment, you may get an error on some of the repos
saying that oparent is unresolvable. Using the example
settings.xml file should solve this problem:
`Setting Up Your Development Environment#MavenExamplesettings.xml <https://wiki.onap.org/display/DW/Setting+Up+Your+Development+Environment#SettingUpYourDevelopmentEnvironment-MavenExamplesettings.xml>`__
- Build aai-common, traversal, and resources
..code:: bash
cd ~/LF/AAI/aai-common
mvn clean install # Should result in BUILD SUCCESS
cd ~/LF/AAI/resources
mvn clean install # Should result in BUILD SUCCESS
cd ~/LF/AAI/logging-service
mvn clean install # Should result in BUILD SUCCESS
cd ~/LF/AAI/traversal # I had to add the following to traversal/pom.xml to get
traversal to build:
..code:: xml
<repositories><repository><id>maven-restlet</id><name>Restlet repository</name><url>https://maven.restlet.com</url></repository></repositories>
mvn clean install # Should result in BUILD SUCCESS
- Titan setup
1. Modify both titan-cached.properties and
titan-realtime.properties to the following (for all MS’s that
will connect to the local Cassandra backend)
..code:: bash
storage.backend=\ *cassandra*
storage.hostname=\ *localhost*
2. update
~/LF/AAI/resources/aai-resources/bundleconfig-local/etc/appprops/titan-cached.properties
3. update
~/LF/AAI/resources/aai-resources/bundleconfig-local/etc/appprops/titan-realtime.properties
4. update
~/LF/AAI/traversal/aai-traversal/bundleconfig-local/etc/appprops/titan-cached.properties
5. update
~/LF/AAI/traversal/aai-traversal/bundleconfig-local/etc/appprops/titan-realtime.properties
6. The following property can be added to specify the keyspace
name, each time you do this step (g) should be done. If not
specified Titan will try to create/use a defaulted keyspace
named titan.
..code:: bash
storage.cassandra.keyspace=<keyspace name>
7. From the resources MS run the create db schema standalone program.
8. ***NOTE***: The first thing that would need to be done is adding
the schema to the local instance. (this will need to be done
whenever using a new keyspace or after wiping the data).
Runnable class org.onap.aai.dbgen.GenTester with the following vm
args.
..code:: bash
-DAJSC_HOME=~/LF/AAI/resources -DBUNDLECONFIG\_DIR="bundleconfig-local"
9. Here's the command I used, and it worked:
..code:: bash
cd ~/LF/AAI; java -DAJSC_HOME=/home/jimmy/LF/AAI/resources/aai-resources
-DBUNDLECONFIG_DIR="bundleconfig-local" -cp
aai-common/aai-core/target/aai-core-1.1.0-SNAPSHOT.jar:resources/aai-resources/target/aai-resources.jar:resources/aai-resources/target/userjars/\*
org.onap.aai.dbgen.GenTester
- Start the "resources" microservice
1. Resources runs on port 8446. Go to the resources directory
..code:: bash
cd ~/LF/AAI/resources
2. Set the debug port to 9446
..code:: bash
export MAVEN_OPTS="-Xms1024m -Xmx5120m -XX:PermSize=2024m
-Xdebug -Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,address=9446,server=y,suspend=n"
3. Start the microservice
..code::bash
mvn -P runAjsc
16. Verify the resources microservice (this example uses Postman utility
for Google Chrome)
1. | Use basic auth, user = AAI, pw = AAI
2. | Set the X-TransactionId header (in the example below, the value is
| 9999)
3. | Set the X-FromAppId header (in the example below, the value is
| jimmy-postman)
4. | Perform a GET of https://127.0.0.1:8443/aai/v11/network/vces
5. | You should see an error as below, 404 Not Found, ERR.5.4.6114.
| This indicates that the service is functioning normally:
+------------------------------------------+
| |image1| |
+------------------------------------------+
18. Start the "traversal" microservice
1. | Traversal runs on port 8447. Go to the traversal directory
..code:: bash
$ cd ~/LF/AAI/traversal
2. | Set the debug port to 9447
| $ export MAVEN_OPTS="-Xms1024m -Xmx5120m -XX:PermSize=2024m
-Xdebug -Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,address=9447,server=y,suspend=n"
3. | Start the microservice
| $ mvn -P runAjsc
| Should see something like this: 2017-07-26
12:46:35.524:INFO:oejs.Server:com.att.ajsc.runner.Runner.main():
Started @25827ms
- Verify the traversal microservice
1. | Set up the widget models
| This will set up the postman to add widget models: `Add Widget Models.postman_collection.json <https://wiki.onap.org/download/attachments/10782088/Add%20Widget%20Models.postman_collection.json?version=2&modificationDate=1501102559000&api=v2>`__ `NamedQuery.postman_collection.json <https://wiki.onap.org/download/attachments/10782088/NamedQuery.postman_collection.json?version=2&modificationDate=1501102582000&api=v2>`__
2. | Create a runner using this file:
`models.csv <https://wiki.onap.org/download/attachments/10782088/models.csv?version=1&modificationDate=1501100140000&api=v2>`__
3. | Run the test runner
| |image2|
4. | Add a named query called "getComponentList" (this named query is used by VID):
`NamedQuery.postman_collection.json <ificationDate=1501102582000&api=v2>`__
| |image3|
5. | Add objects:
`Add Instances for Named Query.postman_collection.json <https://wiki.onap.org/download/attachments/10782088/Add%20Instances%20for%20Named%20Query.postman_collection.json?version=1&modificationDate=1501102617000&api=v2>`__
6. | Execute named-query:
`Execute Named Query.postman_collection.json <https://wiki.onap.org/download/attachments/10782088/Execute%20Named%20Query.postman_collection.json?version=1&modificationDate=1501102658000&api=v2>`__
| You should see something like the following:
| |image4|
- Your A&AI instance is now running, both the resources and traversal
microservices are working properly with a local titan graph.
