Docker帮助文档 - 使用篇

1. 安装Docker

x
#1.卸载旧的版本
yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine
#2.安装工具
yum install -y yum-utils
​
#3.设置镜像的仓库(国内阿里云镜像地址)
yum-config-manager \
    --add-repo \
    http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
​
#4.更新yum软件包索引
yum makecache fast
​
#5.安装Docker相关的内容 ce 社区版，ee 企业版
yum install docker-ce docker-ce-cli containerd.io
​
#6.启动docker
systemctl start docker
​
#7.docker随系统启动
systemctl enable docker
​
#8.配置阿里云镜像加速器
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://lyywjmta.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

2. 安装Docker-compose

x
#1.下载
curl -L https://get.daocloud.io/docker/compose/releases/download/1.29.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
​
#2.授权
chmod +x /usr/local/bin/docker-compose
​
#3.查看是否安装成功
docker-compose version

3. 安装 jully-project

1. 创建目录

x
#1.创建docker-compse目录
[root@localhost ~]# mkdir /home/docker-compose-jully
​
#2.创建数据卷目录
[root@localhost home]# mkdir -p /home/jully-volumes/main/{logs,tomcat/logs} /home/jully-volumes/{attachments,sync}
[root@localhost home]# cd jully-volumes/
[root@localhost jully-volumes]# 

2. 下载docker-compose.yml文件

x
[root@localhost home]# cd /home/docker-compose-jully
[root@localhost docker-compose-jully]# curl http://www.jullyupdate.cn/docker/compose/download>>docker-compose.yml
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  1447  100  1447    0     0  29090      0 --:--:-- --:--:-- --:--:-- 29530
[root@localhost docker-compose-jully]# ls
docker-compose.yml

3. 修改docker-compose.yml文件

1. 设置客户ID参数

x
#1.检查配置是否正确
[root@localhost docker-compose-jully]# docker-compose config
#如果出现如下警告，则表明没有设置客户ID
WARNING: The JULLY_CUSTOMER_ID variable is not set. Defaulting to a blank string.
​
#2.指定客户ID,在profile的最后增加如下语句
[root@localhost docker-compose-jully]# vim /etc/profile
export JULLY_CUSTOMER_ID=DOCKER_01
​
#3.生效环境变量
[root@localhost docker-compose-jully]# source /etc/profile
​
#4.查看环境变量
[root@localhost docker-compose-jully]# echo $JULLY_CUSTOMER_ID
DOCKER_01

2. 修改timezon

xxxxxxxxxx
#1.设置timezone，(以Asia/Shanghai为例)
#1-1.先查看当前宿主机的timezone
[root@localhost jully-volumes]# cat /etc/timezone 
cat: /etc/timezon: No such file or directory
#1-2.如果该文件不存在，则需要写入
[root@localhost jully-volumes]# echo 'Asia/Shanghai' >/etc/timezone

3. 修改yml文件

xxxxxxxxxx
version : '3.8'

4. 升级jully-project

xxxxxxxxxx
#1.停止项目
docker-compose down
​
#2.更新所有镜像，拉取最新的镜像

​
#3.删除none镜像(由升级导致tag变成none的旧镜像)
docker rmi -f $(docker images -aq -f dangling=true)
​
#4.启动项目
docker-compose up -d

5. 常用命令

x
#1.获取长容器ID
docker inspect --format="{{.Id}}" tomcat01
​
#2.容器外部复制到容器内部
docker cp /home/docker-compose-jully/jully d200f4e546ef14837b27d46ca6ab953ffee45ec8b6d18711b2333737eab25c57:/usr/local/tomcat/webapps
