How to deploy web application in openshift command line

To deploy a web application in OpenShift using the command-line interface (CLI), follow these steps: Create a new project: Before deploying your application, you need to create a new project. You can do this using the oc new-project command. For example, to create a project named “myproject”, run the following command:javascriptCopy codeoc new-project myproject Create an application: Use the oc…

If you want to run a local Red Hat OpenShift on your Laptop then this guide is written just for you. This guide is not meant for Production setup or any use where actual customer traffic is anticipated. CRC is a tool created for deployment of minimal OpenShift Container Platform 4 cluster and Podman container runtime on a local computer. This is fit for development and testing purposes only. Local OpenShift is mainly targeted at running on developers’ desktops. For deployment of Production grade OpenShift Container Platform use cases, refer to official Red Hat documentation on using the full OpenShift installer. We also have guide on running Red Hat OpenShift Container Platform in KVM virtualization; How To Deploy OpenShift Container Platform on KVM Here are the key points to note about Local Red Hat OpenShift Container platform using CRC: The cluster is ephemeral Both the control plane and worker node runs on a single node The Cluster Monitoring Operator is disabled by default. There is no supported upgrade path to newer OpenShift Container Platform versions The cluster uses 2 DNS domain names, crc.testing and apps-crc.testing crc.testing domain is for core OpenShift services and apps-crc.testing is for applications deployed on the cluster. The cluster uses the 172 address range for internal cluster communication. Requirements for running Local OpenShift Container Platform: A computer with AMD64 and Intel 64 processor Physical CPU cores: 4 Free memory: 9 GB Disk space: 35 GB 1. Local Computer Preparation We shall be performing this installation on a Red Hat Linux 9 system. $ cat /etc/redhat-release Red Hat Enterprise Linux release 9.0 (Plow) OS specifications are as shared below: [jkmutai@crc ~]$ free -h total used free shared buff/cache available Mem: 31Gi 238Mi 30Gi 8.0Mi 282Mi 30Gi Swap: 9Gi 0B 9Gi [jkmutai@crc ~]$ grep -c ^processor /proc/cpuinfo 8 [jkmutai@crc ~]$ ip ad 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens18: mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether b2:42:4e:64:fb:17 brd ff:ff:ff:ff:ff:ff altname enp0s18 inet 192.168.207.2/24 brd 192.168.207.255 scope global noprefixroute ens18 valid_lft forever preferred_lft forever inet6 fe80::b042:4eff:fe64:fb17/64 scope link noprefixroute valid_lft forever preferred_lft forever For RHEL register system If you’re performing this setup on RHEL system, use the commands below to register the system. $ sudo subscription-manager register --auto-attach Registering to: subscription.rhsm.redhat.com:443/subscription Username: Password: The registered system name is: crc.example.com Installed Product Current Status: Product Name: Red Hat Enterprise Linux for x86_64 Status: Subscribed The command will automatically associate any available subscription matching the system. You can also provide username and password in one command line. sudo subscription-manager register --username --password --auto-attach If you would like to register system without immediate subscription attachment, then run: sudo subscription-manager register Once the system is registered, attach a subscription from a specific pool using the following command: sudo subscription-manager attach --pool= To find which pools are available in the system, run the commands: sudo subscription-manager list --available sudo subscription-manager list --available --all Update your system and reboot sudo dnf -y update sudo reboot Install required dependencies You need to install libvirt and NetworkManager packages which are the dependencies for running local OpenShift cluster.

### Fedora / RHEL 8+ ### sudo dnf -y install wget vim NetworkManager ### RHEL 7 / CentOS 7 ### sudo yum -y install wget vim NetworkManager ### Debian / Ubuntu ### sudo apt update sudo apt install wget vim libvirt-daemon-system qemu-kvm libvirt-daemon network-manager 2. Download Red Hat OpenShift Local Next we download CRC portable executable. Visit Red Hat OpenShift downloads page to pull local cluster installer program. Under Cluster select “Local” as option to create your cluster. You’ll see Download link and Pull secret download link as well. Here is the direct download link provided for reference purposes. wget https://developers.redhat.com/content-gateway/rest/mirror/pub/openshift-v4/clients/crc/latest/crc-linux-amd64.tar.xz Extract the package downloaded tar xvf crc-linux-amd64.tar.xz Move the binary file to location in your PATH: sudo mv crc-linux-*-amd64/crc /usr/local/bin sudo rm -rf crc-linux-*-amd64/ Confirm installation was successful by checking software version. $ crc version CRC version: 2.7.1+a8e9854 OpenShift version: 4.11.0 Podman version: 4.1.1 Data collection can be enabled or disabled with the following commands: #Enable crc config set consent-telemetry yes #Disable crc config set consent-telemetry no 3. Run Local OpenShift Cluster in Linux Computer You’ll run the crc setup command to create a new Red Hat OpenShift Local Cluster. All the prerequisites for using CRC are handled automatically for you. $ crc setup CRC is constantly improving and we would like to know more about usage (more details at https://developers.redhat.com/article/tool-data-collection) Your preference can be changed manually if desired using 'crc config set consent-telemetry ' Would you like to contribute anonymous usage statistics? [y/N]: y Thanks for helping us! You can disable telemetry with the command 'crc config set consent-telemetry no'.

Your first Business Rules application on OpenShift: from Zero to Hero in 30 minutes

We disclosed how to convey a current JBoss BRMS/Drools rules extend onto an OpenShift DecisionServer. We made a choice/business-rules microservice on OpenShift Container Platform that was actualized by a BRMS application. The bilingual way of a microservice engineering enabled us to utilize the best usage (a guidelines motor) for this given usefulness (business rules execution) in our design.

The venture we utilized was a current standards extend that was accessible on GitHub. We did however not clarify how one can make a venture sans preparation in the JBoss BRMS Business Central condition and convey it on OpenShift Container Platform. That is the thing that we will investigate in this article.

Building the standards extend

Red Hat JBoss BRMS gives a workbench, creating condition and venture and guidelines vault called "Business Central". We will utilize Business Central to make our tenets venture, characterize our information display, and make our principles.

We give a Red Hat JBoss BRMS Installation Demo that gives a simple establishment of the BRMS stage. It would be ideal if you take after this demo to introduce and begin the stage. Once the stage is begun, we can make our venture. The venture will be a straightforward "Advance Application" demo (truth be told, it will be founded on one of our current demo's, which can be found here).

Open "Business Central" at "http://localhost:8080/business-focal" and give the username (brmsAdmin) and secret key (jbossbrms1!) (on the off chance that you've introduced the stage in a Docker compartment, utilize the URL of your Docker have as clarified in the README of the Install Demo). We initially need to make a purported Organizational Unit (OU) in the "Business Central" interface:

Tap on "Composing - > Administration"

Tap on "Hierarchical Units - > Manage Organizational Units"

Tap on "Include" and make another Organizational Unit with name "Demos" (you can leave alternate fields in the screen exhaust).

Presently will make another vault in which we can store our venture:

Tap on "Stores - > New storehouse"

Give it the name "advance" and dole out it to the "Demos" OU we made prior (leave "Oversaw Repository" unchecked).

Our next assignment is to make the venture:

Tap on "Creating - > Project Authoring"

Tap on "New Item - > Project"

Give the accompanying points of interest:

– Project Name: loandemo

– Group ID: com.redhat.demos

– Artifact ID: loandemo

– Version: 1.0

Making the Data Model

Since we have a venture, we can make our information display. In this illustration, we will make a basic information demonstrate comprising of 2 classes: Applicant and Loan.

Tap on "New Item - > Data Object"

Give the protest the name "Candidate"

Set the bundle to "com.redhat.demos.loandemo"

Give the question two fields:

– creditScore: int (Label: CreditScore)

– name: String (Label: Name)

Next, make an information question with name "Credit" in bundle "com.redhat.demos.loandemo" with the accompanying fields:

Sum: int (Label: Amount)

endorsed: boolean (Label: Approved)

Span: int (Label: Duration)

InterestRate: twofold (Label: InterestRate)

Make a point to spare the articles utilizing the "spare" catch (upper right corner) of the editorial manager. We can now make our standards.

Composing the tenets

We will make our tenets as a choice table:

Tap on "New Item - > Guided Decision Table"

Give it the name "LoanApproval"

Set the bundle to "com.redhat.demos.loan"

Try to choose "Expanded section, values characterized in table body"

Our choice table will comprise of 4 Constraint segments and one Action section. Our Constraint sections characterize the purported Left-Hand-Side of our tenets, the "when" part. The Action section characterizes the Right-Hand-Side or "at that point" part.

To include a Condition section:

Tap on the "+" sign beside "Choice Table"

At last, we have to design our Action section:

Click again on "New Column"

Select "Set the estimation of a field"

Give the accompanying esteems:

– Fact: l (this is our Loan certainty that we characterized in our Condition segments)

– Field: endorsed

– Column header: Approved?

Spare the Decision Table. We can now set the qualities in our choice table. Each column in our table characterizes a run the show. Whenever finish, the table ought to resemble this:

Arranging the venture for OpenShift S2I manufactures

The Red Hat JBoss BRMS Decision Server in OpenShift Container Platform utilizes the supposed S2I, or Source-to-Image, idea to manufacture its OpenShift (Docker) holder pictures. Basically, you give S2I the source code of your standards extend, and the manufacture framework will utilize Maven to assemble the KJAR (Knowledge JAR) containing the information model and guidelines, send this KJAR onto the Decision Server and make the compartment picture.

Since S2I utilizes Maven, we initially need to ensure that our venture is buildable by Maven. To check this, we clone the venture onto our nearby filesystem. Business Central uses a Git storehouse for capacity under the spreads, so we can essentially utilize our most loved Git instrument to clone the BRMS vault:

> git clone ssh://brmsAdmin@localhost:8001/advance

Take note of that the Git execution of Business Central uses a more established open key calculation (DAS), which may oblige you to add the accompanying settings to your SSH arrangement document (on Linux and macOS this record is situated at "~/.ssh/config").

Have localhost

HostKeyAlgorithms +ssh-dss

After the venture has been effectively cloned, go to the "advance/loandemo" catalog and run "mvn clean introduce" to begin the Maven assemble. On the off chance that all his right, this will create an assemble disappointment:

This is on the grounds that our space demonstrate contains Java explanations from the "kie-programming interface" library, in any case, that reliance is not characterized in the "pom.xml" extend descriptor of our venture. This reliance is not required for fabricates done in Business Central, as Business Central gives this JAR on the manufacture way verifiably. In any case, we have to expressly characterize this reliance in our "pom.xml" petition for our neighborhood and Decision Server S2I Maven works to succeed.

Add the accompanying reliance to the "pom.xml" record of the venture:

<dependencies>

<dependency>

<groupId>org.kie</groupId>

<artifactId>kie-api</artifactId>

<version>6.4.0.Final-redhat-13</version>

<scope>provided</scope>

</dependency>

</dependencies>

Take note of the "gave" scope, as we just require this reliance at assemble time. At runtime, this reliance is given by the Decision Server stage.

Run the construct once more: "mvn clean introduce". The manufacture ought to now succeed. We can confer these progressions and drive them back to our Git store in Business Central with the accompanying charges:

> git include pom.xml

> git confer - m "Added kie-programming interface reliance to POM."

> git push

Making the venture available to OpenShift S2I

As clarified before, the BRMS Decision Server S2I assemble takes the source code of your venture, for instance from a Git storehouse, arranges the sources into a KJAR, sends the KJAR onto the Decision Server and fabricates the OpenShift picture (nitty gritty data about the xPaaS BRMS picture for OpenShift can be found in the manual). In this way, the S2I fabricate needs access to our venture's source code.

The Cluster Logging Operator creates and manages the components of the logging stack in your OpenShift or OKD 4.x cluster. Cluster logging is used to aggregate all the logs from your OpenShift Container Platform cluster, such as application container logs, node system logs, audit logs, and so forth. In this article we will install the Logging Operator and create a Cluster Logging Custom Resource (CR) to schedule cluster logging pods and other resources necessary to support cluster logging. By using an operator, the initial deployment, upgrades, and maintenance of the cluster logging is the responsibility of Operator and not SysAdmin work. Install Cluster Logging Operator on OpenShift / OKD 4.x The default Cluster Logging Custom Resource (CR) is named instance. This CR can be modified to define a complete cluster logging deployment that includes all the components of the logging stack to collect, store and visualize logs. The Cluster Logging Operator watches the ClusterLogging Custom Resource and adjusts the logging deployment accordingly. We will be performing the deployments from the command line interface. The focus of this article is the Log collection part. We will have other articles explaining Logs storage and visualization. Step 1: Create Operators namespace We will create a Namespace called openshift-logging for the Logging operator. Create a new object YAML file for namespace creation: cat ocp_cluster_logging_namespace.yaml apiVersion: v1 kind: Namespace metadata: name: openshift-logging annotations: openshift.io/node-selector: "" labels: openshift.io/cluster-logging: "true" openshift.io/cluster-monitoring: "true" EOF Apply the file for actual namespace creation. oc apply -f ocp_cluster_logging_namespace.yaml Step 2: Create OperatorGroup object Next is the installation of Cluster Logging Operator. Create an OperatorGroup object YAML by running the following commands. cat cluster-logging-operatorgroup.yaml apiVersion: operators.coreos.com/v1 kind: OperatorGroup metadata: name: cluster-logging namespace: openshift-logging spec: targetNamespaces: - openshift-logging EOF Create the OperatorGroup object: oc apply -f cluster-logging-operatorgroup.yaml Step 3: Subscribe a Namespace to the Cluster Logging Operator. We need to subscribe a Namespace to the Cluster Logging Operator. But first create a Subscription object YAML file. cat cluster-logging-sub.yaml apiVersion: operators.coreos.com/v1alpha1 kind: Subscription metadata: name: cluster-logging namespace: openshift-logging spec: channel: "4.4" # Set Channel name: cluster-logging source: redhat-operators sourceNamespace: openshift-marketplace EOF Create the Subscription object which deploys the Cluster Logging Operator the openshift-logging Namespace: oc apply -f cluster-logging-sub.yaml Verify installation: $ oc get csv -n openshift-logging NAME DISPLAY VERSION REPLACES PHASE clusterlogging.4.4.0-202009161309.p0 Cluster Logging 4.4.0-202009161309.p0 Succeeded elasticsearch-operator.4.4.0-202009161309.p0 Elasticsearch Operator 4.4.0-202009161309.p0 elasticsearch-operator.4.4.0-202009041255.p0 Succeeded Step 4: Create a Cluster Logging instance Create an instance object YAML file for the Cluster Logging Operator: cat cluster-logging-instance.yaml apiVersion: "logging.openshift.io/v1" kind: "ClusterLogging" metadata: name: "instance" namespace: "openshift-logging" spec: managementState: "Managed" curation: type: "curator" curator: schedule: "30 3 * * *" collection: logs: type: "fluentd" fluentd: EOF Create the Logging instance: oc apply -f cluster-logging-instance.yaml Check pods running after some minutes.

Project Quay is a scalable container image registry that enables you to build, organize, distribute, and deploy containers. With Quay you can create image repositories, perform image vulnerability scanning and robust access controls. We had covered installation of Quay on a Linux distribution using Docker. How To Setup Red Hat Quay Registry on CentOS / RHEL / Ubuntu In this guide, we will review how you can deploy Quay container registry on OpenShift Container Platform using Operator. The operator we’ll use is provided in the Operators Hub. If you don’t have an OpenShift / OKD cluster running and would like to try this article, checkout our guides below. Setup Local OpenShift 4.x Cluster with CodeReady Containers How to Setup OpenShift Origin (OKD) 3.11 on Ubuntu How To run Local Openshift Cluster with Minishift The Project Quay is made up of several core components. Database: Used by Red Hat Quay as its primary metadata storage (not for image storage). Redis (key, value store): Stores live builder logs and the Red Hat Quay tutorial. Quay (container registry): Runs the quay container as a service, consisting of several components in the pod. Clair: Scans container images for vulnerabilities and suggests fixes. Step 1: Create new project for Project Quay Let’s begin by creating a new project for Quay registry. $ oc new-project quay-enterprise Now using project "quay-enterprise" on server "https://api.crc.testing:6443". ..... You can also create a Project from OpenShift Web console. Click create button and confirm the project is created and running. Step 2: Install Red Hat Quay Setup Operator The Red Hat Quay Setup Operator provides a simple method to deploy and manage a Red Hat Quay cluster. Login to the OpenShift console and select Operators → OperatorHub: Select the Red Hat Quay Operator. Select Install then Operator Subscription page will appear. Choose the following then select Subscribe: Installation Mode: Select a specific namespace to install to Update Channel: Choose the update channel (only one may be available) Approval Strategy: Choose to approve automatic or manual updates Step 3: Deploy a Red Hat Quay ecosystem Certain credentials are required for Accessing Quay.io registry. Create a new file with below details. $ vim docker_quay.json "auths": "quay.io": "auth": "cmVkaGF0K3F1YXk6TzgxV1NIUlNKUjE0VUFaQks1NEdRSEpTMFAxVjRDTFdBSlYxWDJDNFNEN0tPNTlDUTlOM1JFMTI2MTJYVTFIUg==", "email": "" Then create a secret on OpenShift that will be used. oc project quay-enterprise oc create secret generic redhat-pull-secret --from-file=".dockerconfigjson=docker_quay.json" --type='kubernetes.io/dockerconfigjson' Create Quay Superuser credentials secret: oc create secret generic quay-admin \ --from-literal=superuser-username=quayadmin \ --from-literal=superuser-password=StrongAdminPassword \ --from-literal=superuser-email=admin@example.com Where: quayadmin is the Quay admin username StrongAdminPassword is the password for admin user admin@example.com is the email of Admin user to be created Create Quay Configuration Secret A dedicated deployment of Quay Enterprise is used to manage the configuration of Quay. Access to the configuration interface is secured and requires authentication in order for access. oc create secret generic quay-config --from-literal=config-app-password=StrongPassword Replace StrongPassword with your desired password. Create Database credentials secret – PostgreSQL oc create secret generic postgres-creds \ --from-literal=database-username=quay \ --from-literal=database-password=StrongUserPassword \ --from-literal=database-root-password=StrongRootPassword \ --from-literal=database-name=quay These are the credentials for accessing the database server: quay – Database and DB username StrongUserPassword – quay DB user password StrongRootPassword – root user database password

Create Redis Password Credential By default, the operator managed Redis instance is deployed without a password. A password can be specified by creating a secret containing the password in the key password. oc create secret generic redis-password --from-literal=password=StrongRedisPassword Create Quay Ecosystem Deployment Manifest My Red Hat Quay ecosystem configuration file looks like below apiVersion: redhatcop.redhat.io/v1alpha1 kind: QuayEcosystem metadata: name: quay-ecosystem spec: clair: enabled: true imagePullSecretName: redhat-pull-secret updateInterval: "60m" quay: imagePullSecretName: redhat-pull-secret superuserCredentialsSecretName: quay-admin configSecretName: quay-config deploymentStrategy: RollingUpdate skipSetup: false redis: credentialsSecretName: redis-password database: volumeSize: 10Gi credentialsSecretName: postgres-creds registryStorage: persistentVolumeSize: 20Gi persistentVolumeAccessModes: - ReadWriteMany livenessProbe: initialDelaySeconds: 120 httpGet: path: /health/instance port: 8443 scheme: HTTPS readinessProbe: initialDelaySeconds: 10 httpGet: path: /health/instance port: 8443 scheme: HTTPS Modify it to fit you use case. When done apply the configuration: oc apply -f quay-ecosystem.yaml Using Custom SSL Certificates If you want to use custom SSL certificates with Quay, you need to create a secret with the key and the certificate: oc create secret generic custom-quay-ssl \ --from-file=ssl.key=example.key \ --from-file=ssl.cert=example.crt Then modify your Ecosystem file to use the custom certificate secret: quay: imagePullSecretName: redhat-pull-secret sslCertificatesSecretName: custom-quay-ssl ....... Wait for few minutes then confirm deployment: $ oc get deployments NAME READY UP-TO-DATE AVAILABLE AGE quay-ecosystem-clair 1/1 1 1 2m35s quay-ecosystem-clair-postgresql 1/1 1 1 2m57s quay-ecosystem-quay 1/1 1 1 3m45s quay-ecosystem-quay-postgresql 1/1 1 1 5m8s quay-ecosystem-redis 1/1 1 1 5m57s quay-operator 1/1 1 1 70m $ oc get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE quay-ecosystem-clair ClusterIP 172.30.66.1 6060/TCP,6061/TCP 4m quay-ecosystem-clair-postgresql ClusterIP 172.30.10.126 5432/TCP 3m58s quay-ecosystem-quay ClusterIP 172.30.47.147 443/TCP 5m38s quay-ecosystem-quay-postgresql ClusterIP 172.30.196.61 5432/TCP 6m15s quay-ecosystem-redis ClusterIP 172.30.48.112 6379/TCP 6m58s quay-operator-metrics ClusterIP 172.30.81.233 8383/TCP,8686/TCP 70m Running pods in the project: $ oc get pods NAME READY STATUS RESTARTS AGE quay-ecosystem-clair-84b4d77654-cjwcr 1/1 Running 0 2m57s quay-ecosystem-clair-postgresql-7c47b5955-qbc4s 1/1 Running 0 3m23s quay-ecosystem-quay-66584ccbdb-8szts 1/1 Running 0 4m8s quay-ecosystem-quay-postgresql-74bf8db7f8-vnrx9 1/1 Running 0 5m34s quay-ecosystem-redis-7dcd5c58d6-p7xkn 1/1 Running 0 6m23s quay-operator-764c99dcdb-k44cq 1/1 Running 0 70m Step 4: Access Quay Dashboard Get a route URL for deployed Quay: $ oc get route quay-ecosystem-quay quay-ecosystem-quay-quay-enterprise.apps.example.com quay-ecosystem-quay 8443 passthrough/Redirect None

Open the URL on the machine with access to the cluster domain. Use the credentials you configured to login to Quay registry. And there you have it.
