Install Okd On Centos 7
Feb 27, 2017 - A demonstrative article to show the installation and configuration of Openshift Origin on CentOS 7.2. Install RedHat OKD 3.11 on your own server. For a local only install, it is suggested that you use CDK or MiniShift instead of this repo. This install method is targeted for a single node cluster that has a long life. This repository is a set of scripts that will allow you easily install the latest version (3.11) of OKD in a single node fashion.
In this tutorial we will show you how to install FreeIPA on CentOS 7 server. For those of you who didn’t know, FreeIPA is an open source identity management system for Linux/Unix environments which provides centralized account management and authentication, like Microsoft Active Directory or LDAP.FreeIPA has many components, including Kerberos, NTP, DNS, and Dogtag (a certificate system) in order to provide security on your CentOS 7 server.
The full FreeIPA package essentially provides Linux systems with the abilities for centralized authentication, authorization and account information by storing data about users, groups, hosts and all the other objects that are needed to manage security for networks.This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step install FreeIPA open source identity management system on CentOS 7 server. Install FreeIPA on CentOS 7Step 1.
First let’s start by ensuring your system is up-to-date.
OKD is the open source upstream community edition of Red Hat's OpenShift container platform. OKD is a container management and orchestration platform based on and.OKD is a complete solution to manage, deploy, and operate containerized applications that (in addition to the features provided by Kubernetes) includes an easy-to-use web interface, automated build tools, routing capabilities, and monitoring and logging aggregation features.OKD provides several deployment options aimed at different requirements with single or multiple master nodes, high-availability capabilities, logging, monitoring, and more. You can create OKD clusters as small or as large as you need.In addition to these deployment options, OKD provides a way to create a local, all-in-one cluster on your own machine using the oc command-line tool.
This is a great option if you want to try OKD locally without committing the resources to create a larger multi-node cluster, or if you want to have a local cluster on your machine as part of your workflow or development process. In this case, you can create and deploy the applications locally using the same APIs and interfaces required to deploy the application on a larger scale. This process ensures a seamless integration that prevents issues with applications that work in the developer's environment but not in production.This tutorial will show you how to create an OKD cluster using oc cluster up in a Linux box. Install DockerThe oc cluster up command creates a local OKD cluster on your machine using Docker containers. In order to use this command, you need Docker installed on your machine. For OKD version 3.9 and later, Docker 1.13 is the minimum recommended version.

If Docker is not installed on your system, install it by using your distribution package manager. For example, on CentOS or RHEL, install Docker with this command: $ sudo yum install -y dockerOn Fedora, use dnf: $ sudo dnf install -y dockerThis installs Docker and all required dependencies. Configure Docker insecure registryOnce you have Docker installed, you need to configure it to allow the communication with an insecure registry on address 172.30.0.0/16. This insecure registry will be deployed with your local OKD cluster later.On CentOS or RHEL, edit the file /etc/docker/daemon.json by adding these lines. $ docker versionClient:Version: 1.13.1API version: 1.26Package version: docker-1.13.1- 75.git8633870.el7.centos.x8664Go version: go1.9.4Git commit: 8633870 /1.13.1Built: Fri Sep 28 19: OS /Arch: linux /amd64Server:Version: 1.13.1API version: 1.26 (minimum version 1.12 )Package version: docker-1.13.1- 75.git8633870.el7.centos.x8664Go version: go1.9.4Git commit: 8633870 /1.13.1Built: Fri Sep 28 19: OS /Arch: linux /amd64Experimental: falseEnsure that the insecure registry option has been enabled by running docker info and looking for these lines. $ docker info. Skipping long output.Insecure Registries:172.30.0.0 / 16127.0.0.0 / 8 4.
Open firewall portsNext, open firewall ports to ensure your OKD containers can communicate with the master API. By default, some distributions have the firewall enabled, which blocks required connectivity from the OKD containers to the master API. If your system has the firewall enabled, you need to add rules to allow communication on ports 8443/tcp for the master API and 53/udp for DNS resolution on the Docker bridge subnet.For CentOS, RHEL, and Fedora, you can use the firewall-cmd command-line tool to add the rules.

For other distributions, you can use the provided firewall manager, such as or.Before adding the firewall rules, obtain the Docker bridge network subnet's address, like this. $ sudo firewall-cmd -zone okdlocal -list-sources172.17.0.0 / 16$ sudo firewall-cmd -zone okdlocal -list-ports8443 /tcp 53 /udp 8053 /udpYour system is ready to start the cluster. It's time to download the OKD client tools. Download the OKD client toolsTo deploy a local OKD cluster using oc, you need to download the OKD client tools package. For some distributions, like CentOS and Fedora, this package can be downloaded as an RPM from the official repositories. Please note that these packages may follow the distribution update cycle and usually are not the most recent version available.For this tutorial, download the OKD client package directly from the official GitHub repository so you can get the most recent version available.
At the time of writing, this was OKD v3.11.Go to the to get the link to the OKD tools for Linux, then download it with wget. $ cd /Downloads /$ wget https: //github.com /openshift /origin /releases /download /v3.11.0 /openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gzUncompress the downloaded package: $ tar -xzvf openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gzFinally, to make it easier to use the oc command systemwide, move it to a directory included in your $PATH variable. A good location is /usr/local/bin: $ sudo cp openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit /oc /usr /local /bin /One of the nicest features of the oc command is that it's a static single binary.
You don't need to install it to use it.Check that the oc command is working. $ oc login -u system:adminLogged into 'as 'system:admin' using existing credentials.You have access to the following projects and can switch between them with 'oc project ':defaultkube-dnskube-proxykube-publickube-system. myprojectopenshiftopenshift-apiserveropenshift-controller-manageropenshift-core-operatorsopenshift-infraopenshift-nodeopenshift-service-cert-signeropenshift-web-consoleUsing project 'myproject'.$ oc get nodesNAME STATUS ROLES AGE VERSIONlocalhost Ready 52m v1.11.0+d4cacc0Since this is a local, all-in-one cluster, you see only localhost in the nodes list. Smoke-test your clusterNow that your local OKD cluster is running, create a test app to smoke-test it. Use OKD to build and start the sample application so you can ensure the different components are working.Start by logging in as the developer user. $ oc new-app php: 5.6https: //github.com /rgerardi /ocp-smoke-test.git- Found image 92ed8b3 ( 5 months old ) in image stream 'openshift/php' under tag '5.6' for 'php:5.6'Apache 2.4 with PHP 5.6-PHP 5.6 available as container is a base platform for building and running various PHP 5.6 applications and frameworks.
