基于Jenkins自动打包并部署docker环境

基于上一章 基于Jenkins自动打包并部署Tomcat环境_学习新鲜事物的博客-CSDN博客

1、安装docker-ce

在tomcat上创建远程命令

root@tomcat \~\]# mkdir /data

在tomcat上构建 tomcat基础镜像。在构建基础镜像之前需要先安装 Docker 与 JDK。

root@tomcat \~\]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo \[root@tomcat \~\]# yum -y install yum-utils device-mapper-persistent-data lvm2 \[root@tomcat \~\]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 已加载插件：fastestmirror adding repo from: http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo grabbing file http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo

安装dockers启动并查看

root@tomcat \~\]# yum -y install docker-ce \[root@tomcat \~\]# systemctl start docker \[root@tomcat \~\]# systemctl enable docker \[root@tomcat \~\]# docker version Client: Docker Engine - Community Version: 24.0.5 API version: 1.43 Go version: go1.20.6 Git commit: ced0996 Built: Fri Jul 21 20:39:02 2023 OS/Arch: linux/amd64 Context: default Server: Docker Engine - Community Engine: Version: 24.0.5 API version: 1.43 (minimum version 1.12) Go version: go1.20.6 Git commit: a61e2b4 Built: Fri Jul 21 20:38:05 2023 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.6.22 GitCommit: 8165feabfdfe38c65b599c4993d227328c231fca runc: Version: 1.1.8 GitCommit: v1.1.8-0-g82f18fe docker-init: Version: 0.19.0 GitCommit: de40ad0

2 、阿里云镜像加速器

root@tomcat \~\]# cat \<\< END \> /etc/docker/daemon.json \> { \> "registry-mirrors":\[ "https://nyakyfun.mirror.aliyuncs.com"

> }

> END

root@tomcat \~\]# systemctl daemon-reload \[root@tomcat \~\]# systemctl restart docker \[root@tomcat \~\]# cat centos-7-x86_64.tar.gz \| docker import - centos:7 sha256:a94721bf20e6e706ea0ab02bb4283bcd992e760542620aa908143dcf52012e39 \[root@tomcat \~\]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE centos 7 a94721bf20e6 3 seconds ago 589MB

3、构建tomcat 基础镜像

root@tomcat \~\]# mkdir docker-tomcat \[root@tomcat \~\]# cd docker-tomcat/ \[root@tomcat docker-tomcat\]# ls \[root@tomcat docker-tomcat\]# rz \[root@tomcat docker-tomcat\]# ll 总用量 196724 -rw-r--r--. 1 root root 9690027 7月 17 2020 apache-tomcat-8.5.40.tar.gz -rw-r--r--. 1 root root 191753373 7月 17 2020 jdk-8u191-linux-x64.tar.gz \[root@tomcat docker-tomcat\]# vim Dockerfile \[root@tomcat docker-tomcat\]# cat Dockerfile FROM centos:7 MAINTAINER from crushlinux \ #copy jdk and tomcat into image ADD ./apache-tomcat-8.5.40.tar.gz /usr/local/ ADD ./jdk-8u191-linux-x64.tar.gz /usr/local #set variable ENV JAVA_HOME /usr/local/jdk1.8.0_191 ENV PATH $JAVA_HOME/bin:$PATH #container starts up ENTRYPOINT /usr/local/apache-tomcat-8.5.40/bin/startup.sh \&\& tail -F /usr/local/apache-tomcat-8.5.40/logs/catalina.out
