This article describes one of the fastest installation Kubernetes and experience KubeSphere core function of the way, all-in-one mode can be a key installation Kubernetes v1.15.5 and KubeSphere to a Linux machine.
prompt:
- KubeSphere 2.1 is supported
自定义安装各个功能组件, the user can configure the installation component selects the desired machine and business needs , default open only最小化安装, with reference to the installation instructions begin the installation of optional components.- If you use the cloud platform online installation, can be speed up installation by raising bandwidth way.
Prerequisites
We recommend turning off the network firewall.
Step One: Preparing the Host
Refer to the following specifications Prepare a start node host node to meet the requirements of the all-in-oneinstallation mode, the software version in order to prevent conflict, we recommended to choose a clean machine .
Description:
- If you use ubuntu 16.04 is recommended to use the latest version 16.04.5;
- The use ubuntu 18.04, root user is required;
- If the command sudo Debian system is not installed, you need to use the root user before installation to perform
apt update && apt install sudothe installation command sudo command after installation.
| operating system | The minimum placement |
|---|---|
| CentOS 7.5 (64 bit) | CPU: 2 core, RAM: 4 G, system disk: 100 G |
| Ubuntu 16.04/18.04 LTS (64 bit) | CPU: 2 core, RAM: 4 G, system disk: 100 G |
| Red Hat Enterprise Linux Server 7.4 (64 bit) | CPU: 2 core, RAM: 4 G, system disk: 100 G |
| Debian Stretch 9.5 (64 bit) | CPU: 2 core, RAM: 4 G, system disk: 100 G |
Step 2: Prepare the installation package
Download KubeSphere 2.1.0the installation package to be installed the machine, enter the installation directory.
$ curl -L https://kubesphere.io/download/stable/v2.1.0 > installer.tar.gz \
&& tar -zxf installer.tar.gz && cd kubesphere-all-v2.1.0/scriptsStep 3: Install KubeSphere
KubeSphere installation process will be automated environmental monitoring and file, install the platform dependent software, Kubernetes and etcd automated installation, configuration, and storage of automation, after a successful installation can click on to view the version installed by the upper right corner KubeSphere console.
Description:
- Normally you do not need to modify any configuration can be installed directly.
- Network plug-in by default
calico, if you need to be in a custom installation parameters, such as network, storage, load balancer plug-ins, such as an optional component configurationconf/common.yamlspecified or modify files, the reference cluster components configuration instructions .- The default storage with OpenEBS based Local Volume provides persistent storage service, OpenEBS support dynamic application the PV , easy initial installation but is not ready for deployment test at the storage server scenario , a formal environment recommended configuration persistent storage .
- Since the Cluster Kubernetes cluster IP subnet default
10.233.0.0/18, Pod the subnet default10.233.64.0/18, thus the installation KubeSphere IP address range should not be more than two network node duplication, if the conflict can be encountered in the configuration address range fileconf/vars.yamlmodificationkube_service_addressesorkube_pods_subnetparameters.
Reference to the following step starts all-in-one installation:
Explanation: The installation time with the network conditions and bandwidth, machine configuration, factors number of other mounting about node, has tested all-in-one pattern, in good network conditions to a list of specifications minimum configuration is about 20 minutes installation.
1. recommended rootusers install, execute install.shscript:
