Docker免sudo权限本地build脚本

默认docker.sock是root:docker的权限

直接执行docker build会报错如下：

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.30/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&shmsize=0&t=hello-http&target=&ulimits=null: dial unix /var/run/docker.sock: connect: permission denied

1 初始化为docker swarm manager

eval $(docker-machine env node-1)
docker swarm init \
    --advertise-addr $(docker-machine ip node-1)

eval $(docker-machine env node-1)

docker swarm init \

--advertise-addr $(docker-machine ip node-1)

2 获取swarm集群的token

eval $(docker-machine env node-1)
SWARM_MANAGER_TOKEN=$(docker swarm join-token -q manager)
SWARM_WORKER_TOKEN=$(docker swarm join-token -q worker)

eval $(docker-machine env node-1)

SWARM_MANAGER_TOKEN=$(docker swarm join-token -q manager)

SWARM_WORKER_TOKEN=$(docker swarm join-token -q worker)

3 其他机器加入集群(作为manager)

eval $(docker-machine env node-2)
docker swarm join \
    --token $SWARM_MANAGER_TOKEN \
    --advertise-addr $(docker-machine ip node-2) \
    $(docker-machine ip node-1):2377

eval $(docker-machine env node-2)

docker swarm join \

--token $SWARM_MANAGER_TOKEN \

--advertise-addr $(docker-machine ip node-2) \

$(docker-machine ip node-1):2377

4 其他机器加入集群(作为worker)

eval $(docker-machine env node-3)
docker swarm join \
    --token $SWARM_WORKER_TOKEN \
    --advertise-addr $(docker-machine ip node-2) \
    $(docker-machine ip node-1):2377

eval $(docker-machine env node-3)

docker swarm join \

--token $SWARM_WORKER_TOKEN \

--advertise-addr $(docker-machine ip node-2) \

$(docker-machine ip node-1):2377

1 在vbox中创建3个docker的结点(boot2docker)

docker-machine create -d virtualbox node-1

1	docker-machine create -d virtualbox node-1

2 删除vbox中创建的docker结点

docker-machine rm -f node-1

1	docker-machine rm -f node-1

3 停止/启动node

docker-machine start node-1
docker-machine stop node-1

1 2	docker-machine start node-1 docker-machine stop node-1

4 用本地docker直接操作某个结点

eval $(docker-machine env node-1)
docker swarm ....

1 2	eval $(docker-machine env node-1) docker swarm ....

5 获取ip

1 安装docker

sudo apt-get update 
sudo apt-get install     apt-transport-https     ca-certificates     curl     software-properties-common
curl -fsSL http://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
sudo apt-get install docker-ce

sudo apt-get update

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common

curl -fsSL http://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

sudo apt-get install docker-ce

2 安装docker-machine

docker-machine方便管理分布式的docker环境

curl -L https://github.com/docker/machine/releases/download/v0.12.1/docker-machine-`uname -s`-`uname -m` >/tmp/docker-machine &&     chmod +x /tmp/docker-machine &&     sudo cp /tmp/docker-machine /usr/local/bin/docker-machine

1	curl -L https://github.com/docker/machine/releases/download/v0.12.1/docker-machine-`uname -s`-`uname -m` >/tmp/docker-machine && chmod +x /tmp/docker-machine && sudo cp /tmp/docker-machine /usr/local/bin/docker-machine

其中这个０.12.1需要去上面github看最新版是啥
