We will do same practical today but this time using one of the most demanding platform-as-a-service solution. Red Hat OpenShift container platform. I have explained in my previous posts that what extra we can achieve using OpenShift. Please have a look on below posts for more details-
I have logged into my rol account and have oc command ready with me. If you also want to configure oc command you down from here setup as below.
[root@server106 ~]# cd /root/Desktop/
[root@server106 Desktop]# ll

-rwxr-xr-x. 1 root root 120350344 Apr 27 2020 oc
[root@server106 Desktop]# chmod 755 oc
[root@server106 Desktop]# mv oc /usr/bin/
Run [root@server106 Desktop]# oc --version command, if you get options that means command is ready to use.
Step 1 :- Login into your OpenShift environment using below command. Username and paswrord is give in your lab environment. If your username password is correct you will get "Login successful" message.
[root@server106 ~]# oc login https://api.ocp-ap3.prod.nextcle.com:6443

Step 2 :- Run oc --help command to check oc options after that create a project.
[root@server106 Desktop]# oc new-project lw1 [create new project]
[root@server106 ~]# oc get projects [check available project]
NAME DISPLAY NAME STATUS
lw1 Active
[root@server106 ~]# oc get pods [check available pods]
No resources found.
[root@server106 ~]# oc get dc [check available dc(deployment config)]
No resources found.
[root@server106 ~]# oc get bc [check available bc(build config)]
No resources found.
Step 3 :- Create mysql pod, what is pod? to understand in simple language it is box which contain containers.
[root@server106 ~]# oc new-app -e MYSQL_USER=<USERNAME> MYSQL_PASSWORD=<PASSWORD> MYSQL_DATABASE=<DATABASE_NAME> openshift/mysql-56-centos
[root@server106 ~]# oc get pods
NAME READY STATUS RESTARTS AGE
mysql-56-centos7-1-7flz9 1/1 Running 0 65m
mysql-56-centos7-1-deploy 0/1 Completed 0 88m
[root@server106 ~]# oc get dc
NAME REVISION DESIRED CURRENT TRIGGERED BY
mysql-56-centos7 1 1 1 config,image(mysql-56-centos7:latest)
[root@server106 ~]# oc get svc [check service]
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
mysql-56-centos7 ClusterIP 172.30.252.164 <none> 3306/TCP 89m
[root@server106 ~]# oc get is [check image service]
NAME IMAGE REPOSITORY TAGS UPDATED
mysql-56-centos7 default-route-openshift-image-registry.apps.ocp-ap3.prod.nextcle.com
[root@server106 ~]# oc describe pod mysql-56-centos7-1-7flz9 [check all details of pod]
Step 3 :- Create wordpress pod.
[root@server106 ~]# oc new-app https://github.com/wordpress/wordpress
[root@server106 ~]# oc get dc
NAME REVISION DESIRED CURRENT TRIGGERED BY
mysql-56-centos7 2 1 1 config,image(mysql-56-centos7:latest)
wordpress 0 1 0 config,image(wordpress:latest)
[root@server106 ~]# oc get pods
NAME READY STATUS RESTARTS AGE
mysql-56-centos7-1-deploy 0/1 Completed 0 143m
mysql-56-centos7-2-deploy 0/1 Completed 0 15m
mysql-56-centos7-2-wsg9x 1/1 Running 0 6m16s
wordpress-1-build 1/1 Running 0 29s
[root@server106 ~]# oc get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
mysql-56-centos7 ClusterIP 172.30.252.164 <none> 3306/TCP 144m
wordpress ClusterIP 172.30.150.132 <none> 8080/TCP,8443/TCP 82s
[root@server106 ~]# oc expose svc wordpress
route.route.openshift.io/wordpress exposed
[root@server106 ~]# oc get route
NAME HOST/PORT PATH SERVICES PORT TERMINATION WILDCARD
wordpress wordpress-lw1.apps.ocp-ap3.prod.nextcle.com wordpress 8080-tc p None
If you followed the same steps you will be able to access wordpress framwork in your browser using this URL wordpress-lw1.apps.ocp-ap3.prod.nextcle.com.
