Manual Installation

Prior to the deployment, depending on the cluster types you need to generate either of the proxying or serving certificates.

Certificate Description
Proxying Used to secure the communication between Hawtio Online and the Jolokia agents. A client certificate is generated and mounted into the Hawtio Online pod with a secret, to be used for TLS client authentication.
Serving Used to secure the communication between the client and Hawtio Online.

OpenShift

Proxying certificates

For OpenShift, a client certificate must be generated using the service signing certificate authority private key.

Run the following script to generate and set up a client certificate for Hawtio Online:

./scripts/generate-proxying.sh

or if you have Yarn installed, this will also do the same thing:

yarn gen:proxying

Serving certificates

For OpenShift, a serving certificate is automatically generated for your Hawtio Online deployment using the service signing certificate feature.

Kubernetes

Proxying certificates

For Kubernetes, proxying certificates are disabled by default and you don't need to go through the steps.

Warning

This means that client certificate authentication between Hawtio Online and the Jolokia agents is not available by default for Kubernetes, and the Jolokia agents need to disable client certificate authentication so that Hawtio Online can connect to them. You can still use TLS for securing the communication between them.

It is possible to use a proxying client certificate for Hawtio Online on Kubernetes; it requires you to generate or provide a custom CA for the certificate and then mount/configure it into the Jolokia agent for its client certificate authentication.

Serving certificates

For Kubernetes, a serving certificate must be generated manually. Run the following script to generate and set up a certificate for Hawtio Online:

./scripts/generate-serving.sh [-k tls.key] [-c tls.crt] [SECRET_NAME] [CN]

or:

yarn gen:serving [-k tls.key] [-c tls.crt] [SECRET_NAME] [CN]

You can provide an existing TLS key and certificate by passing parameters -k tls.key and -c tls.crt respectively. Otherwise, a self-signed tls.key and tls.crt will be generated automatically in the working directory and used for creating the serving certificate secret.

You can optionally pass SECRET_NAME and CN to customise the secret name and Common Name used in the TLS certificate. The default secret name is hawtio-online-tls-serving and CN is hawtio-online.hawtio.svc.

Manual steps

Instead of running the scripts you can choose to perform everything manually.

For manual steps, see Generating Certificates Manually.

Deployment

Now you can run the following instructions to deploy the Hawtio Online console on your OpenShift/Kubernetes cluster.

There are two deployment modes you can choose from: cluster and namespace.

Deployment Mode Description
Cluster The Hawtio Online console can discover and connect to hawtio-enabled 1 applications deployed across multiple namespaces / projects.
OpenShift: Use an OAuth client that requires the cluster-admin role to be created. By default, this requires the generation of a client certificate, signed with the service signing certificate authority, prior to the deployment. See the Preparation - OpenShift section for more information.
Namespace This restricts the Hawtio Online console access to a single namespace / project, and as such acts as a single tenant deployment.
OpenShift: Use a service account as OAuth client, which only requires admin role in a project to be created. By default, this requires the generation of a client certificate, signed with the service signing certificate authority, prior to the deployment. See the Preparation - OpenShift section for more information.

1. Containers with a configured port named jolokia and that exposes the Jolokia API.

OpenShift

You may want to read how to get started with the CLI for more information about the oc client tool.

To deploy the Hawtio Online console on OpenShift, follow the steps below.

Cluster mode

If you have Yarn installed:

yarn deploy:openshift:cluster

otherwise (two commands):

oc apply -k deploy/openshift/cluster/
./deploy/openshift/cluster/oauthclient.sh

Namespace mode

If you have Yarn installed:

yarn deploy:openshift:namespace

otherwise:

oc apply -k deploy/openshift/namespace/

You can obtain the status of your deployment, by running:

$ oc status
In project hawtio on server https://192.168.64.12:8443

https://hawtio-online-hawtio.192.168.64.12.nip.io (reencrypt) (svc/hawtio-online)
  deployment/hawtio-online deploys hawtio/online:latest
    deployment #1 deployed 2 minutes ago - 1 pod

Open the route URL displayed above from your Web browser to access the Hawtio Online console.

Kubernetes

You may want to read how to get started with the CLI for more information about the kubectl client tool.

To deploy the Hawtio Online console on Kubernetes, follow the steps below.

Cluster mode

If you have Yarn installed:

yarn deploy:k8s:cluster

otherwise:

kubectl apply -k deploy/k8s/cluster/

Namespace mode

If you have Yarn installed:

yarn deploy:k8s:namespace

otherwise:

kubectl apply -k deploy/k8s/namespace/
