fabric8:create-routes

The maven fabric8:create-routes goal queries all the Services in the current namespace which expose ports 80 or 443 and create a new OpenShift Route if one doesn't already exist

You can use the maven property fabric8.domain or the environment variable $KUBERNETES_DOMAIN to define the DNS host to expose services as OpenShift Routes

For a summary of the options see the Maven Property Reference

Default Configuration

The Kubernetes environment and authentication is defined by the kubernetes-api environment variables. In particular:

• KUBERNETES_MASTER - the location of the kubernetes master
• KUBERNETES_NAMESPACE - the default namespace used on operations

Defaults from OpenShift

If no configuration is supplied through maven properties or environment variables, the fabric8:create-routes goal will try to find the current login token and namespace by parsing the users ~/.kube/config file.

This means that if you use the OpenShift command line tool oc you can login and change projects (namespaces in kubernetes speak) and those will be used by default by the fabric8:create-routes goal. e.g.

oc login
oc project cheese
mvn fabric8:create-routes

In the above, if there is no KUBERNETES_NAMESPACE environment variable or maven property called fabric8.namespace then the fabric8:create-routes goal will apply the Kubernetes resources to the cheese namespace.

Example

To generate any missing routes for services use the following goal:

mvn fabric8:create-routes

Note if you are not in a maven project which has the fabric8 maven plugin enabled then you can use the more verbose version:

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

To specify an explicit namespace and domain in recreate mode:

mvn fabric8:create-routes -Dfabric8.domain=foo.acme.com -Dfabric8.namespace=cheese   

Templates

Applying an OpenShift template works the same as a regular List of Kubernetes resources.

One difference is that you may wish to override some of the template parameter values as you apply the template which you can do on the command line via system properties.

mvn fabric8:create-routes -Dfabric8.apply.FOO=bar

The above will apply the OpenShift template defined in target/classes/kubernetes.json overriding the template parameter FOO with the value bar before processing the template and creating/updating the resources.

Maven Properties

The following maven property values are used to configure the behaviour of the apply goal:
