Install Fabric8 on OpenShift

Fabric8 apps have been packaged to make them easy to install on Kubernetes or OpenShift.

Install via the console

If you are already running the fabric8 console you can use it to install all the other Fabric8 apps and quickstarts. If you are not yet running the fabric8 console then try install it via the CLI below.

When you open the fabric8 console select the Apps tab then click on the Run... button (top right green butotn).

This will list all of the installed OpenShift Templates on your installation.

  • To Run any of the installed templates just click the Run button (the green play button).
  • To install any new OpenShift Templates or other Kubernetes resources just drag and drop the JSON file onto the Apps tab!
  • You can download the fabric8 templates 2.2.89 distribution unzip and drag the JSON files you want to install onto the fabric8 console and they should appear on the Run... page

  • You can also install other OpenShift Templates or Kubernetes resources via the oc command line tool:

      oc create -f jsonOrYamlFileOrUrl

Install via the CLI

These instructions assume that you have either

Setup domain

  • setup the KUBERNETES_DOMAIN environment variable for the domain you are installing to. Usually this is a host name or domain name.

e.g. if you are using the fabric8 Vagrant image then use

export KUBERNETES_DOMAIN=vagrant.f8

Downloading all templates

Download and unzip the fabric8 templates 2.2.89 distribution.

e.g.

curl -o fabric8.zip http://repo1.maven.org/maven2/io/fabric8/devops/distro/distro/2.2.89/distro-2.2.89-templates.zip
unzip fabric8.zip
cd main

Once you have found the kubernetes.json file for the app you wish to install type the following using the oc command from OpenShift:

    oc process -v DOMAIN=$KUBERNETES_DOMAIN -f kubernetes.json | oc create -f -

For example to install the fabric8 console then type:

    oc process -v DOMAIN=$KUBERNETES_DOMAIN -f console-2.2.89.json | oc create -f -

Download templates individually

Or to install from the central repository then choose the commands below to suit the application you wish to install:

Console

Provides the base fabric8 console at the vagrant.f8 domain. On OpenShift run the following command:

    export KUBERNETES_DOMAIN=vagrant.f8
    oc process -v DOMAIN=$KUBERNETES_DOMAIN -f \
    http://repo1.maven.org/maven2/io/fabric8/devops/apps/console/2.2.84/console-2.2.84-kubernetes.json \
    | oc create -f -

If you are using kubernetes run:

    kubectl create -f http://central.maven.org/maven2/io/fabric8/apps/console-kubernetes/2.2.104/console-kubernetes-2.2.104-kubernetes.json

Then setup the OpenShift Routes

Management

Provides centralised Logging and Metrics

    oc process -v DOMAIN=$KUBERNETES_DOMAIN -f \
    http://repo1.maven.org/maven2/io/fabric8/devops/packages/management/2.2.89/management-2.2.89-kubernetes.json \
    | oc create -f -

Then setup the OpenShift Routes

Logging

Provides just the centralised Logging

    oc process -v DOMAIN=$KUBERNETES_DOMAIN -f \
    http://repo1.maven.org/maven2/io/fabric8/devops/packages/logging/2.2.89/logging-2.2.89-kubernetes.json \
    | oc create -f -

Then setup the OpenShift Routes

Metrics

Provides just the centralised Metrics

    oc process -v DOMAIN=$KUBERNETES_DOMAIN -f \
    http://repo1.maven.org/maven2/io/fabric8/devops/packages/metrics/2.2.89/metrics-2.2.89-kubernetes.json \
    | oc create -f -

Then setup the OpenShift Routes

iPaaS

Provides the fabric8 console and the Integration Platform As A Service

    oc process -v DOMAIN=$KUBERNETES_DOMAIN -f \
    http://central.maven.org/maven2/io/fabric8/apps/ipaas/2.2.89/ipaas-2.2.89-kubernetes.json \
    | oc create -f -

Then setup the OpenShift Routes

Continuous Delivery

Provides a Continuous Integration and Continuous Delivery system.

The complete Continuous Delivery installation.

    oc process -v DOMAIN=$KUBERNETES_DOMAIN -f \
    http://repo1.maven.org/maven2/io/fabric8/devops/packages/cd-pipeline/2.2.89/cd-pipeline-2.2.89-kubernetes.json \
    | oc create -f -

Then setup the OpenShift Routes

Creating Routes

If you install via the command line then you will need to create the OpenShift Routes for any services you created. Note that this is done automatically if you create applications via the fabric8 console.

To do this use the mvn fabric8:create-routes goal.

Note that this command can be run in any folder; it doesn't need to be run from inside a maven project.

Before you start make sure you have setup your local machine have logged in and setup the environment variables etc.

If you have defined the $KUBERNETES_DOMAIN environment variable then you can use the following command:

mvn io.fabric8:fabric8-maven-plugin:2.2.89:create-routes

Otherwise you can be specific and specify the domain you wish to use:

mvn io.fabric8:fabric8-maven-plugin:2.2.89:create-routes -Dfabric8.domain=my.acme.com

You could then setup a wildcard DNS rule on *.$KUBERNETES_DOMAIN to point to the IP address of your OpenShift master or HAProxy installation. Or you could add custom entries to your /etc/hosts file for each service.

If you are using the Vagrant image with Linux or OSX you already have wildcard DNS resoultion. For Windows you have to add each new route to %WINDIR%\System32\drivers\etc\hosts. E.g. if your IP address for the OpenShift master/router is 172.28.128.4 (which it is for the fabric8 Vagrant image) then add this to your hosts file to expose the routes as host names:

    172.28.128.4 vagrant.f8 fabric8.vagrant.f8 docker-registry.vagrant.f8 gogs-http.vagrant.f8
    172.28.128.4 gogs-ssh.vagrant.f8 nexus.vagrant.f8 jenkins.vagrant.f8 kibana.vagrant.f8

You should now be able to access the console at http://fabric8.vagrant.f8/
