Installation
============
An environment suitable for running docker containers is recommended.
Using Cloudify deployment
-------------------------
The first possibility is to use blueprints and cfy commands.
Deployment Prerequisite/dependencies
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Make sure that **cfy** is installed and configured to work with the Cloudify deployment.
Make sure the Message Router and Data Router are running.
Deployment steps
^^^^^^^^^^^^^^^^
1. Execute bash on the cloudify manager kubernetes pod.
``kubectl -n onap exec -it <dev-dcaegen2-dcae-cloudify-manager> bash``
2. Download the dfc `blueprint`_.
.. _blueprint: https://gerrit.onap.org/r/gitweb?p=dcaegen2/platform/blueprints.git;a=blob;f=blueprints/reference_templates/k8s-datafile-collector.yaml-template;h=17d2aedec131154b4f5f84a08a099b0364b1e627;hb=HEAD
3. Run Cloudify Install command to install dfc.
``cfy install <dfc-blueprint-path>``
Sample output:
``cfy install k8s-datafile.yaml``
Run '*cfy events list -e 37da3f5f-a06b-4ce8-84d3-8b64ccd81c33'* to retrieve the execution's events/logs.
Validation
^^^^^^^^^^
curl <dcaegen2-dcae-healthcheck> and check if datafile-collector is in *'ready'* state.
Standalone deployment of a container
------------------------------------
DFC is delivered as a docker container based on openjdk:8-jre-alpine. The
host or VM that will run this container must have the docker application
loaded and available to the userID that will be running the DFC container.
Also required is a working DMAAP/MR and DMAAP/DR environment. DFC
subscribes to DMAAP/MR fileReady event as JSON messages and publishes the downloaded files to the DMAAP/DR.
Installation
^^^^^^^^^^^^
The following command will download the Frankfurt version of the datafile image from
nexus and launch it in the container named "datafile":
``docker run -d -p 8100:8100 -p 8433:8433 nexus3.onap.org:10001/onap/org.onap.dcaegen2.collectors.datafile.datafile-app-server:1.3.0``
For another version, it is possible to replace the tag '1.2.3' with any version that seems suitable (including latest).
Available images are visible following this `link`_.
.. _link: https://nexus3.onap.org/#browse/search=keyword%3D*datafile*
Another option is to pull the image first, and then run the image's container with the image ID:
``docker pull nexus3.onap.org:10001/onap/org.onap.dcaegen2.collectors.datafile.datafile-app-server:latest``
``docker images | grep 'datafile'``
``docker run -d -p 8100:8100 -p 8433:8433 <image ID>``
The grep command will display the images corresponding to DFC. There can be several due to remotely or locally built
image, and also to different tags, i.e. different versions.
