容器制作

安装Docker

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

安装工具

yum install -y yum-utils

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

更新yum软件包索引

yum makecache fast

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

启动docker

systemctl start docker

docker随系统启动

systemctl enable docker

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

安装Docker-compose

下载

curl -L https://get.daocloud.io/docker/compose/releases/download/1.29.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

授权

chmod +x /usr/local/bin/docker-compose

查看是否安装成功

docker-compose version

安装 Project

创建docker-compse目录

mkdir /home/docker-compose-jully

创建数据卷目录

mkdir -p /home/jully-volumes/main/{logs,tomcat/logs} /home/jully-volumes/{attachments,sync}

下载docker-compose.yml文件

首先定位到 /home/docker-compose-jully 路径下

curl http://www.jullyupdate.cn/docker/compose/download>>docker-compose.yml

修改docker-compose.yml文件

设置客户ID参数

#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

修改timezon

#设置timezone，(以Asia/Shanghai为例)
#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
#2.如果该文件不存在，则需要写入
[root@localhost jully-volumes]# echo 'Asia/Shanghai' >/etc/timezone

修改yml文件

version : '3.8'

升级Project

此方法今后废弃

#1.停止项目
docker-compose down

#2.更新所有镜像，拉取最新的镜像
docker images --format "{{.Repository}}:{{.Tag}}" | grep ':latest' | xargs -L1 docker pull

#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

其他常用命令

#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
​
#3.删除所有镜像
docker rmi -f $(docker images -aq)
​
#4.删除所有容器
docker rm -f $(docker ps -aq)
