Install v1.5 on Ubuntu 16.04 server (OpenShift Origin)

1. Introduction

This page details how to install OpenShift Origin 1.5, in an Ubuntu 16.04 64-bit server, following the "Method 2: Downloading the Binary" described at:

https://docs.openshift.org/latest/getting_started/administrators.html#getting-started-administrators

2. Pre-requirements

Host preparation reference > https://docs.openshift.org/latest/install_config/install/host_preparation.html#install-config-install-host-preparation

If not yet installed, install 'apt-transport-https' and 'wget':

sudo apt-get install apt-transport-https

sudo apt-get install wget

If not yet installed install docker deamon. REference > https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-16-04

sudo apt-get update

sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

sudo apt-add-repository 'deb https://apt.dockerproject.org/repo ubuntu-xenial main'

sudo apt-get update

sudo apt-cache policy docker-engine

sudo apt-get install -y docker-engine

# check that docker is running

sudo systemctl status docker

# optional, add user to the docker group to avoid having to prepend docker commands with sudo

sudo usermod -aG docker $(whoami)

Docker must be able to pull images from the host system

Reference > https://docs.docker.com/registry/insecure/#deploying-a-plain-http-registry

Ensure you set the --insecure-registry flag

sudo vi /etc/default/docker

# modify or add the DOCKER_OPTS line with the --insecure-registry flag

#DOCKER_OPTS="--insecure-registry 172.30.0.0/16"

DOCKER_OPTS="--insecure-registry 172.30.155.30:5000"

The previous setting didn't work, "/etc/docker/daemon.json" is the platform-independent configuration.

Reference> http://stackoverflow.com/questions/38695515/can-not-pull-push-images-after-update-docker-to-1-12

• Create or modify /etc/docker/daemon.json on the client machine
  • { "insecure-registries":["172.30.155.30:5000"] }
• Restart docker daemon
  • sudo /etc/init.d/docker restart

2. Download the binary from the Releases page

cd /opt

sudo wget https://github.com/openshift/origin/releases/download/v1.5.0/openshift-origin-server-v1.5.0-031cbe4-linux-64bit.tar.gz

3. Untar the binary on the local system (and, optionally, remove the binary)

sudo tar -xvzf openshift-origin-server-v1.5.0-031cbe4-linux-64bit.tar.gz

sudo rm openshift-origin-server-v1.5.0-031cbe4-linux-64bit.tar.gz

4. Add the directory you untarred the release into to your path

cd openshift-origin-server-v1.5.0-031cbe4-linux-64bit

export PATH="$(pwd)":$PATH

5. Launch the server

sudo ./openshift start

6. OpenShift Origin services are secured by TLS. In this path we generate a self-signed certificate on startup which must be accepted by your web browser or client.

You must point oc and curl at the appropriate CA bundle and client key and certificate to connect to OpenShift Origin. Set the following environment variables:

$ export KUBECONFIG="$(pwd)"/openshift.local.config/master/admin.kubeconfig $ export CURL_CA_BUNDLE="$(pwd)"/openshift.local.config/master/ca.crt $ sudo chmod +r "$(pwd)"/openshift.local.config/master/admin.kubeconfig

This is just for example purposes; in a production environment, developers would generate their own keys and not have access to the system keys.

7. What's next?

Now that you have OpenShift Origin successfully running in your environment, try it out by walking through a sample application lifecycle.
