docker总结

一. Docker的安装

1. 准备
   确保内核版本大于3.1 并更新yum

   uname -r
   yum update
   

2. 添加仓库 安装

     yum install -y yum-utils device-mapper-persistent-data lvm2    # 安装yum的辅助包
   
   
     yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo  # 设置阿里的镜像
   
     yum install docker-ce       # 安装
   

3. 启动并加入开机启动

       
       systemctl start docker
       systemctl enable docker
       docker version
   

4. 配置远程访问

      vim /usr/lib/systemd/system/docker.service
   

   把 ExecStart=/usr/bin/dockerd 这一行改为

    ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375
   

   重启docker服务

     systemctl daemon-reload #通知systemd重载配置文件
     systemctl restart docker
   

   此时访问 http://IP:2375/version 可以看到版本为17.05.0-ce

5. 设置国内镜像源
   新增/修改 /etc/docker/daemon.json

       {
                 "registry-mirrors": ["https://registry.docker-cn.com"]
       }
   

6. 安装 docker-compose
   参见GitHub上的shell

    docker-compose --version # 测试安装成功了吗
   

7. TLS
   在/etc/docker目录下新建shell

#!/bin/bash
# 
# Created by L.STONE 
# -------------------------------------------------------------
# 自动创建 Docker TLS 证书
# -------------------------------------------------------------

# 以下是配置信息
# --[BEGIN]------------------------------

CODE="ADMIN"
IP="139.196.122.34"
PASSWORD="ADMIN"
COUNTRY="CN"
STATE="sd"
CITY="qd"
ORGANIZATION="redsoft"
ORGANIZATIONAL_UNIT="Dev"
COMMON_NAME="$IP"
EMAIL="[email protected]"

# --[END]--

# Generate CA key
openssl genrsa -aes256 -passout "pass:$PASSWORD" -out "ca-key-$CODE.pem" 4096
# Generate CA
openssl req -new -x509 -days 365 -key "ca-key-$CODE.pem" -sha256 -out "ca-$CODE.pem" -passin "pass:$PASSWORD" -subj "/C=$COUNTRY/ST=$STATE/L=$CITY/O=$ORGANIZATION/OU=$ORGANIZATIONAL_UNIT/CN=$COMMON_NAME/emailAddress=$EMAIL"
# Generate Server key
openssl genrsa -out "server-key-$CODE.pem" 4096

# Generate Server Certs.
openssl req -subj "/CN=$COMMON_NAME" -sha256 -new -key "server-key-$CODE.pem" -out server.csr

echo "subjectAltName = IP:$IP,IP:127.0.0.1" >> extfile.cnf
echo "extendedKeyUsage = serverAuth" >> extfile.cnf

openssl x509 -req -days 365 -sha256 -in server.csr -passin "pass:$PASSWORD" -CA "ca-$CODE.pem" -CAkey "ca-key-$CODE.pem" -CAcreateserial -out "server-cert-$CODE.pem" -extfile extfile.cnf


# Generate Client Certs.
rm -f extfile.cnf

openssl genrsa -out "key-$CODE.pem" 4096
openssl req -subj '/CN=client' -new -key "key-$CODE.pem" -out client.csr
echo extendedKeyUsage = clientAuth >> extfile.cnf
openssl x509 -req -days 365 -sha256 -in client.csr -passin "pass:$PASSWORD" -CA "ca-$CODE.pem" -CAkey "ca-key-$CODE.pem" -CAcreateserial -out "cert-$CODE.pem" -extfile extfile.cnf

rm -vf client.csr server.csr

chmod -v 0400 "ca-key-$CODE.pem" "key-$CODE.pem" "server-key-$CODE.pem"
chmod -v 0444 "ca-$CODE.pem" "server-cert-$CODE.pem" "cert-$CODE.pem"

# 打包客户端证书
mkdir -p "tls-client-certs-$CODE"
cp -f "ca-$CODE.pem" "cert-$CODE.pem" "key-$CODE.pem" "tls-client-certs-$CODE/"
cd "tls-client-certs-$CODE"
tar zcf "tls-client-certs-$CODE.tar.gz" *
mv "tls-client-certs-$CODE.tar.gz" ../
cd ..
rm -rf "tls-client-certs-$CODE"

# 拷贝服务端证书
mkdir -p /etc/docker/certs.d
cp "ca-$CODE.pem" "server-cert-$CODE.pem" "server-key-$CODE.pem" /etc/docker/certs.d/

# /etc/docker/daemon.json
# {
#   "tlsverify": true,
#   "tlscacert": "/etc/docker/certs.d/ca.pem",
#   "tlscert": "/etc/docker/certs.d/server-cert.pem",
#   "tlskey": "/etc/docker/certs.d/server-key.pem",
#   "hosts": ["tcp://0.0.0.0:2376", "unix:///var/run/docker.sock"]
# }

echo " - 修改 /etc/docker/daemon.json 文件"
cat <

执行脚本，设置 /usr/lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -D -H tcp://0.0.0.0:2376 --tlsverify --tlscacert=/etc/docker/certs.d/ca.pem --tlscert=/etc/docker/certs.d/server-cert.pem --tlskey=/etc/docker/certs.d/server-key.pem

重新加载配置文件重启docker。下载tls-client-certs-.tar 设置idea
URL： https://IP:2376
把下载的文件夹放上，主要去掉-

二 . rabbitmq

1. 拉取镜像

docker pull rabbitmq:management

2. 配置命令

#!/bin/bash
docker run -d --name rabbit -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=redSoft123  -p 5672:5672 -p 15672:15672 rabbitmq:management

添加执行权限 执行ok

3. 常用命令
   停止： docker ps
   docker stop [id]
   如果修改了启动shell的文件 则 docker rm [id]
   启动 docker start [id]
   初次启动 执行如上脚本

三. redis

1. 配置命令

#!/bin/bash
docker run --name redis -p 6379:6379 -v /Users/fengfan/doc/temp/redis_temp_data:/data -d redis:latest  redis-server --appendonly yes --requirepass "123456"
