Docker deployment of continuous integration environment

Deployment preparation

Jenkins Server 10.1.2.183

Docker Server 10.1.2.184

Git/Harbor Server 10.1.2.182

Each service version

CentOS 7.4_x64

Maven 3.5

Tomcat 8

JDK 1.8

Jenkins 2.6

DockerCE 17.06

On the Git server

1. Install Git

Yum install git

2. Create Git users

Useradd gitpasswd git

3. Create a warehouse

Su-gitmkdir solo.git

Cd / home/git/solo.git

Git-bare init

Install the docker service on the git server and the jenkins server to add the domestic mirror source and add the trust to the harbor host in the / etc/docker/daemon.json of the two servers, as follows

{"registry-mirrors": ["https://registry.docker-cn.com"],"

"insecure-registries": ["10.1.2.182"]}

On the jenkins server

Install git, using git's client

Yum install git

Install openjdk1.8

Tar zxvf jdk-8u45-linux-x64.tar.gz & & mv jdk1.8.0_45 / usr/local/

Download the empty project on the git server and create a blank sample repository locally

Git clone 10.1.2.182:/home/git/solo.git # set up a blank warehouse locally

Download the sample project on github

Git clone https://github.com/lizhenliang/tomcat-java-demo

Extract the downloaded sample project, copy the content to the blank warehouse and submit it to the local git repository

Unzip solo-master.zip & & cp-r solo-master/* solo/ & & git add. & & git commit-m "all" # in this case, the simulation is to pull down, modify, and upload the code to the git server.

Remote git server that mentions the soho project

Git push origin master

On the jekins server

Install the jenkins,dockerfile file using dockerfile as follows

Mkdir / root/jenkins;cd / root/jenkins

Cat Dockerfile

FROM jenkins

RUN apt-get update & & apt-get install-y git libltdl-dev

Build a jenkins image

Docker build-t jenkins:v1

Start jenkins

Docker run-d\

-- name jenkins\

-p 808014 080\

-v / var/jenkins_home/:/var/jenkins_home\

-v / usr/local/apache-maven-3.5.0:/usr/local/maven\

-v / usr/local/jdk1.8.0_45:/usr/local/jdk\

-v / var/run/docker.sock:/var/run/docker.sock\

-v $(which docker): / usr/bin/docker\

-v ~ / .ssh:/root/.ssh\

Jenkins:v1

Configure docker and jenkins the login-free configuration for harbor is used for push and pull between git

Ssh-keygen

Ssh-copy-id 10.1.2.182

Visit 10.1.2.183 8080 for jenkins installation

Configure jenkins

Modify jenkins domestic upgrade source

Https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/current/update-center.json

System Management-Global tool configuration

Configure jdk,maven,git

Configure key login to docker hosts on jenkins

Ssh-copy-id 10.1.2.184

Add credentials on the jenkins page credential management

Copy the contents of the / root/.ssh/id_rsa file on the jenkins host into Private Key

Add remote host

System Management-system Settings

Select the ROOT user you added earlier

Deploy the project

Create a new maven project

To configure Git, credentials do not need to be selected, because the jenkins server has been configured to avoid interaction with the git server

PS: in the figure above, if the git account cannot be used, use the root account.

Build option

Build a test to see if maven is finished.

Next, we will package the built package into an image and upload it to the harbor repository.

Build the tomcat basic image on jenkins, and then build the project based on this basic image

Mkdir / root/solo

Cat Dockerfile

FROM centos:7

MAINTAINER www.aliangedu.com

RUN yum install unzip iproute-y

ENV JAVA_HOME / usr/local/jdk

ADD apache-tomcat-8.0.46.tar.gz / usr/local

RUN mv / usr/local/apache-tomcat-8.0.46 / usr/local/tomcat

WORKDIR / usr/local/tomcat

EXPOSE 8080

ENTRYPOINT [". / bin/catalina.sh", "run"]

Construction

Docker build-t 10.1.2.182/test/tomcat:v1. # when building here, mark it directly and push it directly to the warehouse later.

Push

Create a test project in harbor and set the project member chench permission to project administrator or development permission, otherwise you will not be able to push

Docker push 10.1.2.182/test/tomcat:v1

Choose to build the execution script, use Dockfile to build the image in the script, and then upload the image to the GIt repository

Select ssh to execute the shell script to the remote host

Pull the image from Git repository to docker server and run it

The browser accesses the docker host ip:8888 to see if the startup is successful.
