docker swarm+register-web+shipyard搭建

1.swarm安装

swarm安装有很多种服务注册的方式，token、etcd、zookeeper，本文主要以swarm默认的token方式进行安装。因为最新的docker已经集成了swarm,所以从安装docker开始，本文所用操作系统为ubuntu14.04。

          IP           name     service

10.241.81.233 swarm-1  manage

10.241.81.234 swarm-2  worker

10.241.81.235 swarm-3  worker

参考文档：https://store.docker.com/editions/community/docker-ce-server-ubuntu

（1).set up the repository

sudo apt-get -y install 
  apt-transport-https 
  ca-certificates 
  curl

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository 
       "deb [arch=amd64] https://download.docker.com/linux/ubuntu 
       $(lsb_release -cs) 
       stable"
sudo apt-get update

(2)Install the latest version of Docker CE on Ubuntu:

sudo apt-get -y install docker-ce

(3)Run the following command to create a new swarm:

(参考：https://docs.docker.com/engine/swarm/swarm-tutorial/create-swarm/)

mananger:
# docker swarm init --advertise-addr 10.241.81.233
Swarm initialized: current node (cpds4fjp7vv6ttqm4y77vmhae) is now a manager.

To add a worker to this swarm, run the following command:

docker swarm join 
--token SWMTKN-1-5gmmq1w6qsm2zm3wfjkx5at3j2a5mwy1k0qjfp16womwgkqeqj-4ttti9ppo6aqebuw4b1m46vo7 
10.241.81.233:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

worker:
docker swarm join 
--token SWMTKN-1-5gmmq1w6qsm2zm3wfjkx5at3j2a5mwy1k0qjfp16womwgkqeqj-4ttti9ppo6aqebuw4b1m46vo7 
10.241.81.233:2377

在manage上执行docker node ls，查看node的状态:

# docker node ls
ID                            HOSTNAME            STATUS              AVAILABILITY        MANAGER STATUS
7gzxsm1kmzf92bz8tply3j6dj     swarm-2             Ready               Active              
cpds4fjp7vv6ttqm4y77vmhae *   swarm-1             Ready               Active              Leader
ejrnqul66xm1xy62ankhuhvn1     swarm-3             Ready               Active  

2.安装register及register-web (参考:https://hub.docker.com/r/hyper/docker-registry-web/)

docker run -itd --restart=always -p 5000:5000 --name registry-srv registry:2

docker run -idt  --restart=always  -p 8090:8080 --name registry-web --link registry-srv -e REGISTRY_URL=http://10.241.81.233:5000/v2 -e REGISTRY_NAME=localhost:5000 

可以访问register-web，http://10.241.81.233:8090。

修改配置docker配置文件,在DOCKER_OPTS加入--insecure-registry=10.241.81.233:5000，我的原先为空，所以改后状态如下：

# vi /etc/default/docker

DOCKER_OPTS="--insecure-registry=10.241.81.233:5000"

重启docker 就 可以往registerpush镜像了。

3.shipyard安装方式有俩种，一种是脚本，一种是手动，这里选择的脚本安装。

(参考:https://shipyard-project.com/docs/deploy/)

shipyard界面：

curl -sSL https://shipyard-project.com/deploy | bash -s

然后访问 http://10.241.81.233:8080  就有界面了。

 如果需要加入新的节点:

curl -sSL https://shipyard-project.com/deploy | ACTION=node DISCOVERY=etcd://10.241.81.233:4001 bash -s

就能看到有多个节点了，如下图:

也可把register加进去管理：

整个安装部署到此就结束了，后续监控也可以用prometheus收集cadvisor监控swarm的集群状态。
