Rancher

Rancher is an open source software platform that enables organizations to run containers in production. With Rancher, organizations no longer have to build a container services platform from scratch using a distinct set of open source technologies. Rancher supplies the entire software stack needed to manage containers in production.

Quick Start

Env Prepare->Install: Install->Show Log: Show Log->Visit:
  • Env Prepare

Provision a Linux host with 64-bit Ubuntu 16.04, which must have a kernel of 3.10+. You can use your laptop, a virtual machine, or a physical server. Please make sure the Linux host has at least 1GB memory.

Install Docker onto the host.

  • Install Rancher
sudo docker run -d --restart=unless-stopped -p 8080:8080 rancher/server

it will download what it need, just wait…(^_^)

  • Run the Server
houbinbindeMacBook-Pro:~ houbinbin$ sudo docker run -d --restart=unless-stopped -p 8080:8080 rancher/server

  • Get the IP of rancher-server container

下文中 \ 转义符号,实际使用请替换掉。(这和 jekyll 模板冲突)

$   houbinbindeMacBook-Pro:~ houbinbin$ docker inspect --format '\{\{ .NetworkSettings.IPAddress \}\}' rancher-server

    172.17.0.2
  • ADD HOSTS

Click Infrastructure, into Hosts page, click Add Host

We will only be adding the Rancher server host itself. Click Save. By default, the Custom option will be selected, which provides the Docker command to launch the Rancher agent container. There will also be options for cloud providers, which Rancher uses Docker Machine to launch hosts.

rancher-add-host

1、Add the IP of rancher-server container in Something else

http://172.17.0.2:8080

2、Copy and run this:

sudo docker run -d --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher rancher/agent:v1.0.2 http://localhost:8080/v1/scripts/F6FA7D73AD9CEDEFDFFC:1477494000000:sDaoXvLMo7ZYn9rEmf0CLplZ2iI

When you click Close on the Rancher UI, you will be directed back to the Infrastructure -> Hosts view. In a couple of minutes, the host will automatically appear.

It may like this:
