Deploying on OpenShift
This guide covers generating and deploying OpenShift resources based on sane default and user supplied configuration.
Pré-requisitos
Para concluir este guia, você precisa:
-
Cerca de 15 minutos
-
Um IDE
-
JDK 17+ installed with
JAVA_HOME
configured appropriately -
Apache Maven 3.9.9
-
Opcionalmente, o Quarkus CLI se você quiser usá-lo
-
Access to an OpenShift cluster (Minishift is a viable option)
-
OpenShift CLI (Optional, only required for manual deployment)
Iniciando uma aplicação
First, we need a new project that contains the OpenShift extension. This can be done using the following command:
Para usuários do Windows:
-
Se estiver usando cmd, (não use barra invertida '\' e coloque tudo na mesma linha)
-
Se estiver usando o Powershell, envolva os parâmetros '-D' entre aspas duplas, por exemplo, '"-DprojectArtifactId=openshift-quickstart"'
Quarkus offers the ability to automatically generate OpenShift resources based on sane defaults and user supplied configuration. The OpenShift extension is actually a wrapper extension that brings configures the Kubernetes extension with sensible defaults so that it’s easier for the user to get started with Quarkus on OpenShift.
When we added the OpenShift extension to the command line invocation above, the following dependency was added to the pom.xml
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-openshift</artifactId>
</dependency>
implementation("io.quarkus:quarkus-openshift")
Log Into the OpenShift Cluster
Before we build and deploy our application we need to log into an OpenShift cluster. You can log in via the OpenShift CLI:
oc login -u myUsername (1)
1 | You’ll be prompted for the required information such as server URL, password, etc. |
Alternatively, you may log in using the API token:
oc login --token=myToken --server=myServerUrl
You can request the token via the Copy Login Command link in the OpenShift web console. |
Finally, you don’t need to use the OpenShift CLI at all.
Instead, set the quarkus.kubernetes-client.api-server-url
config property and authenticate with the quarkus.kubernetes-client.token
, or quarkus.kubernetes-client.username
and quarkus.kubernetes-client.password
respectively:
quarkus build -Dquarkus.kubernetes-client.api-server-url=myServerUrl -Dquarkus.kubernetes-client.token=myToken
./mvnw install -Dquarkus.kubernetes-client.api-server-url=myServerUrl -Dquarkus.kubernetes-client.token=myToken
./gradlew build -Dquarkus.kubernetes-client.api-server-url=myServerUrl -Dquarkus.kubernetes-client.token=myToken
Build and Deployment
You can trigger a build and deployment in a single step or build the container image first and then configure the OpenShift application manually if you need more control over the deployment configuration.
To trigger a build and deployment in a single step:
quarkus build -Dquarkus.openshift.deploy=true
./mvnw install -Dquarkus.openshift.deploy=true
./gradlew build -Dquarkus.openshift.deploy=true
If you want to test your application immediately then set the quarkus.openshift.route.expose config property to true to expose the service automatically, e.g. add -Dquarkus.openshift.route.expose=true to the command above.
|
When using DeploymentConfig and Service Binding, re-deploying might remove the configuration added by OpenShift to allow service discovery. A new container image build will trigger a refresh of the Quarkus app in OpenShift: -Dquarkus.container-image.build=true which might be enough in most situations. If you need to update the OpenShift resources, you need to delete the binding first to create it again after new deployment.
|
This command will build your application locally, then trigger a container image build and finally apply the generated OpenShift resources automatically.
The generated resources use a Kubernetes Deployment
, but still make use of OpenShift specific resources like Route
, BuildConfig
etc.
As of OpenShift 4.14, the DeploymentConfig object has been deprecated.
|
Since Deployment
is a Kubernetes resource and not OpenShift specific, it can’t possibly leverage ImageStream
resources, as is the case with DeploymentConfig
. This means that the image references need to include the container image registry that hosts the image.
When the image is built, using OpenShift builds (s2i binary and docker strategy) the OpenShift internal image registry image-registry.openshift-image-registry.svc:5000
will be used, unless another registry has been explicitly specified by the user. Please note, that in the internal registry the project/namespace name is added as part of the image repository: image-registry.openshift-image-registry.svc:5000/<project name>/<name>:<tag>
, so users will need to make sure that the target project/namespace name is aligned with the quarkus.container-image.group
.
The deprecation document contains additional information about how to set up/use automatic rollbacks, triggers, lifecycle hooks, and custom strategies.
quarkus.container-image.group=<project/namespace name>
You can use the OpenShift web console to verify that the above command has created an image stream, a service resource and has deployed the application. Alternatively, you can run the following OpenShift CLI commands:
oc get is (1)
oc get pods (2)
oc get svc (3)
1 | Lists the image streams created. |
2 | Get the list of pods. |
3 | Get the list of Kubernetes services. |
Note that the service is not exposed to the outside world by default.
So unless you’ve used the quarkus.openshift.route.expose
config property to expose the created service automatically you’ll need to expose the service manually.
oc expose svc/openshift-quickstart (1)
oc get routes (2)
curl http://<route>/hello (3)
1 | Expose the service. |
2 | Get the list of exposed routes. |
3 | Access your application. |
Configure the OpenShift Application Manually
If you need more control over the deployment configuration you can build the container image first and then configure the OpenShift application manually.
To trigger a container image build:
./mvnw clean package -Dquarkus.container-image.build=true
The build that will be performed is a s2i binary build.
The input of the build is the jar that has been built locally and the output of the build is an ImageStream
that is configured to automatically trigger a deployment.
The base/builder image is specified using base-jvm-image
and base-native-image
for jvm and native mode respectively. An ImageStream for the image is automatically generated, unless these properties are used to reference an existing ImageStreamTag in the internal openshift registry. For example:
quarkus.openshift.base-jvm-image=image-registry.openshift-image-registry.svc:5000/some-project/openjdk-11:17.1.16.
During the build you may find the
For more information, see deploying to Kubernetes. |
Once the build is done we can create a new application from the relevant ImageStream
.
oc get is (1)
oc new-app --name=greeting <project>/openshift-quickstart:1.0.0-SNAPSHOT (2)
oc get svc
oc expose svc/greeting (3)
oc get routes (4)
curl http://<route>/hello (5)
1 | Lists the image streams created. The image stream of our application should be tagged as <project>/openshift-quickstart:1.0.0-SNAPSHOT. |
2 | Create a new application from the image source. |
3 | Expose the service to the outside world. |
4 | Get the list of exposed routes. |
5 | Access your application. |
After this setup the next time the container image is built a deployment to OpenShift is triggered automatically. In other words, you don’t need to repeat the above steps.
Non-S2I Builds
Out of the box the OpenShift extension is configured to use container-image-s2i. However, it’s still possible to use other container image extensions like:
When a non-s2i container image extension is used, an ImageStream
is created that is pointing to an external dockerImageRepository
. The image is built and pushed to the registry and the ImageStream
populates the tags that are available in the dockerImageRepository
.
To select which extension will be used for building the image:
quarkus.container-image.builder=docker
or
quarkus.container-image.builder=jib
Customizing
All available customization options are available in the OpenShift configuration options.
Some examples are provided in the sections below:
Exposing Routes
To expose a Route
for the Quarkus application:
quarkus.openshift.route.expose=true
You don’t necessarily need to add this property in the
The same applies to all properties listed below. |
Securing the Route resource
To secure the incoming connections, OpenShift provides several types of TLS termination to serve certifications. You can read more information about how to secure routes in the official OpenShift guide.
Let’s see an example about how to configure a secured Route using passthrough termination by simply adding the "quarkus.openshift.route.tls" properties:
quarkus.openshift.route.expose=true
quarkus.openshift.route.target-port=https
## Route TLS configuration:
quarkus.openshift.route.tls.termination=passthrough
quarkus.openshift.route.tls.insecure-edge-termination-policy=None
Environment variables
OpenShift provides multiple ways of defining environment variables:
-
key/value pairs
-
import all values from a Secret or ConfigMap
-
interpolate a single value identified by a given field in a Secret or ConfigMap
-
interpolate a value from a field within the same resource
Environment variables from key/value pairs
To add a key/value pair as an environment variable in the generated resources:
quarkus.openshift.env.vars.my-env-var=foobar
The command above will add MY_ENV_VAR=foobar
as an environment variable.
Please note that the key my-env-var
will be converted to uppercase and dashes will be replaced by underscores resulting in MY_ENV_VAR
.
Environment variables from Secret
To add all key/value pairs of Secret
as environment variables just apply the following configuration, separating each Secret
to be used as source by a comma (,
):
quarkus.openshift.env.secrets=my-secret,my-other-secret
which would generate the following in the container definition:
envFrom:
- secretRef:
name: my-secret
optional: false
- secretRef:
name: my-other-secret
optional: false
The following extracts a value identified by the keyName
field from the my-secret
Secret into a foo
environment variable:
quarkus.openshift.env.mapping.foo.from-secret=my-secret
quarkus.openshift.env.mapping.foo.with-key=keyName
This would generate the following in the env
section of your container:
- env:
- name: FOO
valueFrom:
secretKeyRef:
key: keyName
name: my-secret
optional: false
Environment variables from ConfigMap
To add all key/value pairs from ConfigMap
as environment variables just apply the following configuration, separating each
ConfigMap
to be used as source by a comma (,
):
quarkus.openshift.env.configmaps=my-config-map,another-config-map
which would generate the following in the container definition:
envFrom:
- configMapRef:
name: my-config-map
optional: false
- configMapRef:
name: another-config-map
optional: false
The following extracts a value identified by the keyName
field from the my-config-map
ConfigMap into a foo
environment variable:
quarkus.openshift.env.mapping.foo.from-configmap=my-configmap
quarkus.openshift.env.mapping.foo.with-key=keyName
This would generate the following in the env
section of your container:
- env:
- name: FOO
valueFrom:
configMapKeyRef:
key: keyName
name: my-configmap
optional: false
Environment variables from fields
It’s also possible to use the value from another field to add a new environment variable by specifying the path of the field to be used as a source, as follows:
quarkus.openshift.env.fields.foo=metadata.name
Changing the generated deployment resource
Beside generating a Deployment
resource, you can also choose to get either a DeploymentConfig
, StatefulSet
, Job
, or a CronJob
resource instead via application.properties
:
quarkus.openshift.deployment-kind=StatefulSet
Generating Job resources
If you want to generate a Job resource, you need to add the following property via the application.properties
:
quarkus.openshift.deployment-kind=Job
If you are using the Picocli extension, by default the Job resource will be generated. |
You can provide the arguments that will be used by the Kubernetes Job via the property quarkus.openshift.arguments
. For example, adding the property quarkus.openshift.arguments=A,B
.
Finally, the Kubernetes job will be launched every time that is installed in OpenShift. You can know more about how to run Kubernetes jobs in this link.
You can configure the rest of the Kubernetes Job configuration using the properties under quarkus.openshift.job.xxx
(see link).
Generating CronJob resources
If you want to generate a CronJob resource, you need to add the following property via the application.properties
:
quarkus.openshift.deployment-kind=CronJob
# Cron expression to run the job every hour
quarkus.openshift.cron-job.schedule=0 * * * *
CronJob resources require the Cron expression to specify when to launch the job via the property quarkus.openshift.cron-job.schedule . If not provide, the build will fail.
|
You can configure the rest of the Kubernetes CronJob configuration using the properties under quarkus.openshift.cron-job.xxx
(see link).
Validação
A conflict between two definitions, e.g. mistakenly assigning both a value and specifying that a variable is derived from a field, will result in an error being thrown at build time so that you get the opportunity to fix the issue before you deploy your application to your cluster where it might be more difficult to diagnose the source of the issue.
Similarly, two redundant definitions, e.g. defining an injection from the same secret twice, will not cause an issue but will indeed report a warning to let you know that you might not have intended to duplicate that definition.
Backwards compatibility
Previous versions of the OpenShift extension supported a different syntax to add environment variables. The older syntax is still supported but is deprecated, and it’s advised that you migrate to the new syntax.
Old |
New |
||
Plain variable |
|
|
|
From field |
|
|
|

|
|
All from |
|
|
|
From one |
|
|
|
|
|
||
From one |
|
|
|
|
|
If you redefine the same variable using the new syntax while keeping the old syntax, ONLY the new version will be kept, and a warning will be issued to alert you of the problem. For example, if you define both
quarkus.openshift.env-vars.my-env-var.value=foobar and quarkus.openshift.env.vars.my-env-var=newValue , the extension will only generate an environment variable MY_ENV_VAR=newValue and issue a warning.
|
Mounting volumes
The OpenShift extension allows the user to configure both volumes and mounts for the application.
Any volume can be mounted with a simple configuration:
quarkus.openshift.mounts.my-volume.path=/where/to/mount
This will add a mount to my pod for volume my-volume
to path /where/to/mount
The volumes themselves can be configured as shown in the sections below:
Knative - OpenShift Serverless
OpenShift also provides the ability to use Knative via the OpenShift Serverless functionality.
The first order of business is to instruct Quarkus to generate Knative resources by setting:
quarkus.kubernetes.deployment-target=knative
In order to leverage OpenShift S2I to build the container image on the cluster and use the resulting container image for the Knative application, we need to set a couple of configuration properties:
# set the Kubernetes namespace which will be used to run the application
quarkus.container-image.group=geoand
# set the container image registry - this is the standard URL used to refer to the internal OpenShift registry
quarkus.container-image.registry=image-registry.openshift-image-registry.svc:5000
The application can then be deployed to OpenShift Serverless by enabling the standard quarkus.kubernetes.deploy=true
property.

Assuming the container port has been set (as per above comment), if execAction or tcpSocketAction are not set, an HTTP probe will be used automatically even if no path is set (which will result in the root path being used). If Smallrye Health is used, the path will automatically be set according to the health check path. Environment variable: Show more |
