=== Using the {project_openshift_product_name} Image Streams and Application Templates
|

[IMPORTANT]
|
|
====
|
|
Red Hat JBoss Middleware for OpenShift images are pulled on demand from the secured Red Hat Registry: link:https://access.redhat.com/containers/[registry.redhat.io], which requires authentication. To retrieve content, you will need to log into the registry using the Red Hat account.
|
|
|
|
To consume container images from *_registry.redhat.io_* in shared environments such as OpenShift, it is recommended for an administrator to use a Registry Service Account, also referred to as authentication tokens, in place of an individual person's Red Hat Customer Portal credentials.
|
|
|
|
To create a Registry Service Account, navigate to the link:https://access.redhat.com/terms-based-registry/[Registry Service Account Management Application], and log in if necessary.
|
|
|
|
. From the *_Registry Service Accounts_* page, click *_Create Service Account_*.
|
|
. Provide a name for the Service Account, for example *_registry.redhat.io-sa_*. It will be prepended with a fixed, random string.
|
|
.. Enter a description for the Service Account, for example *_Service account to consume container images from registry.redhat.io._*.
|
|
.. Click *_Create_*.
|
|
. After the Service Account was created, click the *_registry.redhat.io-sa_* link in the *_Account name_* column of the table presented on the *_Registry Service Accounts_* page.
|
|
. Finally, click the *_OpenShift Secret_* tab, and perform all steps listed on that page.
|
|
|
|
See the link:https://access.redhat.com/RegistryAuthentication[Red Hat Container Registry Authentication] article for more information.

====
|
|
|
|
. Ensure that you are logged in as a cluster administrator or a user with project administrator access to the global openshift project:
|
|
|
|
. Choose a command based on your version of OpenShift Container Platform.
|
|
|
|
.. If you are running an OpenShift Container Platform v3 based cluster instance on (some) of your master host(s), perform the following:
|
|
+
|
|
[source,bash,subs="attributes+,macros+"]
|
|
----
|
|
$ oc login -u system:admin
|
|
----
|
|
.. If you are running an OpenShift Container Platform v4 based cluster instance, link:https://docs.openshift.com/container-platform/latest/cli_reference/openshift_cli/getting-started-cli.html#cli-logging-in_cli-developer-commands[log in to the CLI] as the link:https://docs.openshift.com/container-platform/latest/authentication/remove-kubeadmin.html#understanding-kubeadmin_removing-kubeadmin[kubeadmin] user:

----
|
|
$ oc login -u kubeadmin -p password \https://openshift.example.com:6443
|

|
|
|
|
. Run the following commands to update the core set of {project_name} {project_version} resources for OpenShift in the `openshift` project:
|
|
+
|
|
[source,bash,subs="attributes+,macros+"]
|
|
----
|

|
|
oc replace -n openshift --force -f \
|

{project_templates_url}/$\{resource}
|
|
done
|
|
----
|
|
. Run the following command to install the {project_name} {project_version} OpenShift image streams in the `openshift` project:
|
|
+
|
|
[source,bash,subs="attributes+,macros+"]

=== Deploying the {project_name} Image
|
|
[[Preparing-SSO-Authentication-for-OpenShift-Deployment]]
|
|
==== Preparing the Deployment
|
|
Log in to the OpenShift CLI with a user that holds the _cluster:admin_ role.
|
|
|
|
. Create a new project:
|
|
+
|
|
[source,bash,subs="attributes+,macros+"]
|
|
----
|
|
$ oc new-project sso-app-demo
|
|
----
|
|
. Add the `view` role to the link:{ocpdocs_default_service_accounts_link}[`default`] service account. This enables the service account to view all the resources in the sso-app-demo namespace, which is necessary for managing the cluster.
|
|
+
|
|
[source,bash,subs="attributes+,macros+"]
|
|
----
|
|
$ oc policy add-role-to-user view system:serviceaccount:$(oc project -q):default

|
|
|
|
==== Deploying the {project_name} Image using the Application Template
|
|
|
|
===== Deploying the Template using OpenShift CLI
|
|
|
|
. List the available {project_name} application templates:
|
|
+
|
|
[source,bash,subs="attributes+,macros+"]
|
|
----
|
|
$ oc get templates -n openshift -o name | grep -o '{project_templates_version}.\+'
|
|
{project_templates_version}-https
|
|
{project_templates_version}-postgresql
|
|
{project_templates_version}-postgresql-persistent
|
|
{project_templates_version}-x509-https
|
|
{project_templates_version}-x509-postgresql-persistent
|
|
----
|
|
. Deploy the selected one:
|
|
+
|
|
[source,bash,subs="attributes+,macros+"]
|
|
----
|
|
$ oc new-app --template={project_templates_version}-x509-https
|

An example {project_name} 7 application. For more information about using this template, see https://github.com/jboss-openshift/application-templates.

A new {project_name} service has been created in your project. The admin username/password for accessing the master realm using the {project_name} console is IACfQO8v/nR7llVSVb4Dye3TNRbXoXhRpAKTmiCRc. The HTTPS keystore used for serving secure content, the JGroups keystore used for securing JGroups communications, and server truststore used for securing {project_name} requests were automatically created using OpenShift's service serving x509 certificate secrets.

Alternatively, perform one of the following procedures to deploy the {project_name} template by using the OpenShift 3.x or 4.x web console.
|
|
|
|
===== Deploying the Template using the OpenShift 3.x Web Console
|
|
|
|
. Log in to the OpenShift web console and select the _sso-app-demo_ project space.
|
|
. Click *Add to Project*, then *Browse Catalog* to list the default image streams and templates.
|
|
. Use the *Filter by Keyword* search bar to limit the list to those that match _sso_. You may need to click *Middleware*, then *Integration* to show the desired application template.
|
|
. Select an {project_name} application template. This example uses *_{project_name} {project_versionDoc} (Ephemeral)_*.
|
|
. Click *Next* in the *Information* step.
|
|
. From the *Add to Project* drop-down menu, select the _sso-app-demo_ project space. Then click *Next*.
|
|
. Select *Do not bind at this time* radio button in the *Binding* step. Click *Create* to continue.
|
|
. In the *Results* step, click the *Continue to the project overview* link to verify the status of the deployment.
