Getting Started: Cloning the Repository

To kick off your DevOps journey, you’ll need to clone the necessary scripts from the GitHub repository. Here’s how:

git clone https://github.com/feiskyer/ops.git --recurse-submodules
cd ops

Kubernetes Setup

Kubernetes is the heartbeat of container orchestration. Let’s dive into creating your Kubernetes cluster master!

Creating a Kubernetes Cluster Master

Install Kubernetes with Docker by running the following:

sh
# Setup Kubernetes master.
sudo ./kubernetes/install-kubernetes.sh

Adding a New Node

To add nodes to your cluster, you’ll need to establish a token and define your cluster’s settings:

sh
# Setup token and CIDR first.
# replace this with yours.
export TOKEN=xxxx
export MASTER_IP=x.x.x.x
export CONTAINER_CIDR=10.244.2.024
# Setup and join the new node.
sudo ./kubernetes/add-node.sh

Customizing Your Setup

Customization is key in DevOps. You have various options for configuration:

• Use mirrors in China: export USE_MIRROR=true (Only required for Chinese users)
• Container runtime:
  • export CONTAINER_RUNTIME=docker
  • Supported options: docker, containerd, cri-o, gvisor
• CNI network plugins:
  • export NETWORK_PLUGIN=flannel
  • Supported options: flannel, calico, weave, azure, bridge
• Cluster CIDR: export CLUSTER_CIDR=10.244.0.016
• Container CIDR: export CONTAINER_CIDR=10.244.1.024 (Only required for bridge network plugin)

Kubernetes Manifest Examples

Docker Installation

Next on our journey is the installation of Docker:

sh
sudo ./kubernetes/install-docker.sh

Open vSwitch (OVS)

To install Open vSwitch, follow these commands:

sh
# Install ovs: 
sudo ./ovs/ovs-install.sh
# Start ovn: 
sudo ./ovs/ovn-start.sh

Miscellaneous Installations

Finally, don’t forget to install Go programming language:

sh
sudo ./misc/golang-install.sh

Troubleshooting Tips

Even the best plans can go awry. Here are some troubleshooting tips to help you out:

• Check for any missing dependencies or outdated scripts.
• Ensure you have the correct permissions for installation commands. Use sudo as needed.
• If encountering network issues, verify your network configurations are correct, particularly the CIDR.
