应用场景

如果服务器上有很多镜像和容器，每次查看通过URL，命令行十分不方便，可以通过安装配置shipyard容器管理工具来统一监控管理。

操作步骤

1. 安装docker

按如下步骤操作：
 # wget http://mirrors.hustunique.com/epel/6/i386/epel-release-6-8.noarch.rpm
 # rpm -ivh epel-release-6-8.noarch.rpm
 # yum install docker-io
 # service docker start
 # chkconfig docker on

查看docker状态：
 # service docker status

2. 安装shipyard

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

由于网络原因，可能会失败，多尝试几次。
安装完成后，即可按照此，进行访问： http://ip:8080 admin/shipyard

如下图所示：

但是发现问题了，页面中容器，镜像，节点，什么都没有。造成的原因可能是：1.容器启动顺序不对，2.端口2375未映射到

3. 解决第一个问题，编辑start_shipyard.sh文件，加入如下命令，然后执行：

 # sh start_shipyard.sh restart

#!/bin/bash
PREFIX=shipyardrestart_rethinkdb() {
    docker $1$PREFIX-rethinkdb
}restart_discovery() {
    docker $1$PREFIX-discovery
}restart_certs() {
    docker $1$PREFIX-certs
}restart_proxy() {
    docker $1$PREFIX-proxy
}restart_swarm_manager() {
    docker $1$PREFIX-swarm-manager
}restart_swarm_agent() {
    docker $1$PREFIX-swarm-agent
}restart_controller() {
    docker $1$PREFIX-controller
}if [ $#-ne1 ];thenecho"Usage:sh shipyard_restart.sh  {start|stop|restart}"exit1fiecho"Restarting Shipyard Begin."echo"-> ${1}ing Database"
restart_rethinkdb $1echo"-> ${1}ing Discovery"
restart_discovery $1echo"-> ${1}ing Cert Volume"
restart_certs $1echo"-> ${1}ing Proxy"
restart_proxy $1echo"-> ${1}ing Swarm Manager"
restart_swarm_manager $1echo"-> ${1}ing Swarm Agent"
restart_swarm_agent $1echo"-> ${1}ing Controller"
restart_controller $1echo"${1}ing Shipyard Done."

启动：
 # sh  shipyard.sh start

停止：
 # sh shipyard.sh stop

重启
 # sh shipyard.sh restart

4. 解决第二个问题，编辑/etc/sysconfig/docker文件，加入如下红色语句。最后重启docker。

# /etc/sysconfig/docker
#
# Other arguments to pass to the docker daemon process
# These will be parsed by the sysv initscript and appended
# to the arguments list passed to docker -d

other_args='-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock'
DOCKER_CERT_PATH=/etc/docker

# Resolves: rhbz#1176302 (docker issue #407)
DOCKER_NOWARN_KERNEL_VERSION=1

# Location used for temporary files, such as those created by
# # docker load and build operations. Default is /var/lib/docker/tmp
# # Can be overriden by setting the following environment variable.
# # DOCKER_TMPDIR=/var/tmp

# service docker restart

访问连接发现，容器，镜像，nodes都有了！
