【docker】docker部署爬虫实战

环境

系统：ubuntu18.04
docker：19.03.5

Docker概述

一、安装docker

1、卸载已安装的docker

 sudo apt autoremove docker
 
 sudo apt autoremove docker-engine
 
 sudo apt autoremove docker.io

2、执行自动安装docker的脚本

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

安装成功后出现：

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker dell

Remember that you will have to log out and back in for this to take effect!

WARNING: Adding a user to the "docker" group will grant the ability to run
         containers which can be used to obtain root privileges on the
         docker host.
         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
         for more information.

此时，docker CE 的稳定(stable)版本已经安装在系统中。

3、新建docker用户组，并将当前用户加入

sudo groupadd docker
sudo usermod -aG docker 当前用户的用户名

4、设置docker开机自启动，并重启docker使配置生效

sudo systemctl enable docker
sudo systemctl start docker

sudo systemctl daemon-reload
sudo systemctl restart docker

5、验证docker的启动

docker run hello-world

出现如下信息说明启动成功：

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker ID:
 https://hub.docker.com/

二、创建docker镜像

Docker日志默认存储位于：/var/lib/docker/containers/<container_id>/*.log
