–link 就是在我们的hosts配置增加了一个172.18.0.3 tomcat02 104ddec21caa

我们真实玩Docker已经不建议使用–link了

自定义网络！不适用docker0!

docker0问题：他不支持容器名连接访问！

网络模式

bridge:桥接docker(默认,自己创建也使用bridge模式）

none:不配置网络

host:和宿主机共享网络

container:容器网络连通！（用的少！局限很大）

测试
# 我们直接启动的命令 --net bridge,而这个就是我们的docker0
docker run -d -P --name tomcat01 tomcat
docker run -d -P --name tomcat01  --net bridge tomcat

# docker0特点，域名不能访问，--link可以打通连接

卸载Docler

  1. Uninstall the Docker Engine, CLI, and Containerd packages:

    $ sudo yum remove docker-ce docker-ce-cli containerd.io

  2. Images, containers, volumes, or customized configuration files on your host are not automatically removed. To delete all images, containers, and volumes:

    $ sudo rm -rf /var/lib/docker

1.准备工作

yum install python-pip      # pip 是python包管理工具
yum -y install epel-release # 报错的话执行

2.为项目创建目录

$ mkdir composetest
$ cd composetest

3.的项目的目录中创建一个名为app.py的文件，内容如下：

import time

import redis
from flask import Flask

app = Flask(__name__)
cache = redis.Redis(host='redis', port=6379)

def get_hit_count():
    retries = 5
    while True:
        try:
            return cache.incr('hits')
        except redis.exceptions.ConnectionError as exc:
            if retries == 0:
                raise exc
            retries -= 1
            time.sleep(0.5)

@app.route('/')
def hello():
    count = get_hit_count()
    return 'Hello World! I have been seen {} times.\n'.format(count)

在本例中，redis是应用程序网络上redis容器的主机名，我们使用的Redis是默认端口6379

4.在项目目录中，创建名为requirements.txt的文件,内容

flask
redis

5.在项目目录中，创建名为Dockerfile的文件

FROM python:3.6-alpine
ADD . /code
WORKDIR /code
RUN pip install -r requirements.txt
CMD ["python", "app.py"]

6.在项目目录中创建一个名为docker-compose.yml的文件

version: "3.8"
services:
  web:
    build: .
    ports:
      - "5000:5000"
    volumes:
      - .:/code
  redis:
    image: "redis:alpine"

7.启动项目运行

Build and run your app with Compose
# docker-compose up

services:
  daleiapp:
    build: .
    image: kuangapp
    depends_on:
      - redis
    ports:
      - "8088:8088"
  redis:

How nodes work

Estimated reading time: 2 minutes

Docker Engine 1.12 introduces swarm mode that enables you to create a cluster of one or more Docker Engines called a swarm. A swarm consists of one or more nodes: physical or virtual machines running Docker Engine 1.12 or later in swarm mode.

There are two types of nodes: managers and workers.
