Jenkins installation and configuration

Pull Jenkins
```
docker pull jenkins
Copy the code
```
Look at mirror
```
docker images
Copy the code
```
Create Jenkins directory
```
mkdir -p /home/jenkins
Copy the code
```

Modify the permissions

chown -R 1000 /home/jenkins/
Copy the code

Start the Jenkins

docker run -itd -p 9090:8080 -p 50000:50000 --name jenkins --privileged=true  -v /home/jenkins:/var/jenkins_home jenkins:latest
Copy the code

access

192.168.0.193:9090

According to the prompt, enter the container for the/var/jenkins_home/secrets/initialAdminPassword files looking for a password

Docker exec it ddd2e4dcf731 /bin/bash

View password: cat/var/jenkins_home/secrets/initialAdminPassword

Password: a762c435c13e41e08df4f5ebe83b2a8a

Note: in the view/home/Jenkins/secrets/initialAdminPassword can also, because when we start Jenkins with command (see above the green part of the command) specifies the/home/Jenkins directory mounted to the inside of the container/var/jenk Ins_home directory, so all files generated in the container will be generated on the host
Enter the installation plug-in.
Recommended plug-in installation
Emma: Oh, my God. It’s all failed
Create an administrator account to facilitate login
Click System Management to check the cause of plug-in installation failure, as shown in the picture below. It should be caused by the version being too low
As shown in the figure below, download the updated version of the WAR package is provided below, but here we are pulled by Docker, unlike tomcat startup, you can directly change the war package
Because docker pulled it directly, I decided to delete the image of the existing version of the container, version 2.190.3

First stop the existing Jenkins container: docker stop container ID

Then delete the container: docker rm container ID

Last delete image: docker RM Image ID
Check the latest version of the official website and available for docker pull version

[Jenkins download and deployment](www.jenkins.io/download/)
Docker pulls version 2.190.3
1. pull
```
Docker pull Jenkins: 2.190.3Copy the code
```
  As shown below, version 2.190.3 is not found
2. Go to docker’s official website to search, as shown in the picture below
3. Execute the command above, as shown in the picture below to download, wait until the download is complete and start, repeat the steps above, no repeat textures here
```
Docker pull Jenkins/Jenkins: 2.190.3 - centosCopy the code
```

Download successfully. Start

docker run -itd -p 9090:8080 -p 50000:50000 --name jenkins --privileged=true- v/home/Jenkins: / var/jenkins_home Jenkins/Jenkins: 2.190.3 - centosCopy the code

After startup, access 192.168.0.193:9090, view the password login, and reinstall the recommended plug-ins as shown below. Most of them were installed successfully
Select continue to create the first user
After logging in to the plugin management, the plugin has been installed, found that the Build Time plug-in exists, so I don’t care
Enter global tools configuration, configure JKD, Maven, etc…

Configure settings. XML to find maven’s installation directory, as shown below

Note: The directory I configured above is still the Maven directory in the Jenkins container. Remember to copy the entire /home/maven/ directory to the /home/jenkins/ directory after modifying the setting. XML file below

After the configuration shown above, you also need to change the repository address of settings.xml to a domestic site to speed up the download, as shown below
```
Vim/home/maven/apache maven - 3.6.3 / conf/Settings. The XMLCopy the code

Enter the container to view: as shown below

Note: The recommended plug-in does not have maven plug-ins. You need to manually search for the installation, enter the plug-in management, and wait until the installation is complete

Then create a project and upload it to SVN

Here, I create a SVN repository on SpringTools and upload a project to the repository. The repository address is the same as the repository address after SVN is installed

Submit the project, as shown in the picture below. Sorry, for the convenience of fast SVN file directory structure is not very standard, please refer to Baidu to establish a standard file directory structure

Check whether the access is successful. As shown in the following figure, the access is successful. Then configure automatic deployment
Create a new Maven project, as shown below
The above is the whole process of Jenkins’ pulling and releasing the SVN code. Of course, it is not finished yet. It is just pulling and carrying out basic configuration, without updating and starting our project on the server in real time
1. First of all, we download a Publish over SSH plug-in from system management ————> Plug-in Management, as shown in the picture below. I have already downloaded it. If you haven’t downloaded it, you can click the optional plug-in to search and download it, which will be used below
2. Step 2, enter the system configuration for system administration and configure the Docker host related things, as shown in the figure below
  
  Fill in the above parameters in the location shown above
  
  PassPhrase: indicates the password of the server
  
  Name: Any Name
  
  Hostname: server IP address (192.168.0.193)
  
  Username: indicates the Username used to log in to the server.
  
  Remote Diractory: Remote Diractory: Remote Diractory: Remote Diractory: Remote Diractory: Remote Diractory: Remote Diractory: Remote Diractory
  
  After filling in, click the button in the lower right to test, and then click “Save” to exit
3. Then click the project to enter the project configuration, as shown below
  
  Publish over SSH: Publish over SSH: Publish over SSH: Publish over SSH: Publish over SSH
  
  The parameters are described as follows:
  
  Name: Select the server we configured earlier in the system administration System configuration
  
  **/*.jar, which means that all generated JAR packages are moved to the folder under the remote directory configuration
  
  Remote directory: is the directory I created to put the jar package of the project, as shown in the picture below, is the main file, the code is not needed, here in order to avoid misleading, so the code
  
  Here I have filled in the absolute path where docker.sh resides, as shown in the figure above
  
  When you click on Jenkins to build a project, Jenkins will go to SVN and pull the latest one
  
  The code is compiled and packaged using maven, which we configured, and then executed as shown below
  
  The parameters we configured will first generate the JAR in the remote directory we configured, and then execute the configured jar
  
  The script docker.sh also has an advanced button below that needs to be checked as shown in the following image, otherwise the target folder will be generated as shown in the above image
  
  Note: There is a big hole here, as shown below. Both Pre Steps and Post Steps can be configured as above, so what is the difference? The general meaning of baidu is
  
  Pre Steps is the pre-processing step, that is, execute the command first, then compile and package the JAR package
  
  Post Steps are post-processing, that is, package, compile, generate jar package, and then execute command
  
  I configured the above information in Pre Steps, so I need to build the project twice each time to really see the changes in the SVN code, why? The reason is that the jar package is not packaged and compiled when the command is executed first, so each execution is the last JAR package, and the second build will run the last jar package, so why do you need to build the project twice each time to see the changes in the SVN code, and then changed to Post Steps Compile the package first, then execute the command. The correct step is to compile and execute the script first
4. The above is the configuration of the whole Jenkins, and the scripts in the server are introduced below. All the files are shown in the picture below. In order to avoid misleading, I have typed the files I created blind, and the two files in the picture below are respectively used when Jenkins configured SVN and Gitlab
  
  The Dockerfile file is as follows

The above is all the configuration of docker+ SVN + Jenkins + Maven automatic deployment
1. First look at the Java file and return Hello Word, as shown below
2. Jenkins build
3. access
  
  http://192.168.0.193:9999/springboot/hello
  
  Does return Hello Word (port 9999 is configured in Dockerfile, and the image docker runs on also specifies port 9999)
4. Modifying Java files
  
  Change to Hello Liucong and submit to SVN
5. To build again
6. To visit again
  
  http://192.168.0.193:9999/springboot/hello
  
  If Hello Liucong is returned, the process is successfully deployed
7. This is the deployment configuration of the entire process

Gitlab is automatically deployed, installed and configured

The environment

gitLab:

Environment is the same as above, gitLab is added

For other configurations, refer to the above files. This time, we mainly install the configurations above gitLab, Nginx and Jenkins

GitLab installation

GitLab image pull
```
docker pull gitlab/gitlab-ce
Copy the code
```
Gitlab-ce is a stable version. If the version number is not specified, the latest version is selected by default
Look at mirror
```
docker images
Copy the code
```

Run the mirror

docker run -d  -p 443:443 -p 80:80 -p 222:22 --name gitlab --restart always -v /home/gitlab/config:/etc/gitlab -v /home/gitlab/logs:/var/log/gitlab -v /home/gitlab/data:/var/opt/gitlab gitlab/gitlab-ce
Copy the code

-d: background running

-p: maps ports inside a container outward

–name: indicates the name of the container

-v: mounts the data folder or log configuration file in the container to the host directory

configuration

The gitLab container works fine as described above, but when creating a project on GitLab, the URL access address of the generated project is generated according to the hostname of the container, which is the container ID. As gitlab server, we need a fixed URL to access the address, then need to configure the gitlab. Rb (hosting path: / home/gitlab/config/gitlab rb)
1. Edit the file and modify the following contents
```
vim /home/gitlab/config/gitlab.rb
Copy the code
```
  External_url ‘http://192.168.0.193′(Specifies the access address used for the HTTP protocol. The default port number is 80.)
  
  Gitlab_rails [‘gitlab_ssh_host’] = ‘192.168.0.193’(set SSH access address and port)
  
  Gitlab_rails [‘gitlab_shell_ssh_port’] = 222(this port is 222 mapped from port 22 when run)
2. Save the exit
Restart the GitLab container
```
docker restart gitlab
Copy the code
```
access

http://192.168.0.193

(because my gitlab port is 80, so the browser URL does not need to enter the port number, if the port number is not 80, then open as: IP: port number), enter the new root user password for the first time, set only confirm line, then click login
Registered account
Create a project, again using the project in the tutorial above as an example
Open local Git bash and generate an SSH private key using the following command
1. Generate the private key
```
ssh-keygen -t rsa -C '***********@gmail.com'
Copy the code
```
  The public and private keys here generate the following directories
  
  Your identification has been saved in /c/Users/Administrator/.ssh/id_rsa.
  
  Your public key has been saved in /c/Users/Administrator/.ssh/id_rsa.pub.
2. Look at the private key
```
cat ~/.ssh/id_rsa.pub
Copy the code
```
  ~ denotes the user directory, for example c:\Users\Administrator on my Windows
  
  ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCiKZTTL8mMmsh4YZhF4cICbpwJlpXDlzxxrPAyldf7Ywh47EYcMZ9YrcLkifQeiMrPk+a6wn7Q9HKjOcZFBRS8g8QW NMD/+S6u6hXuhgePwFPYxg6mTDDNpyaw YcxislxLIL3rPYbMg2gmX+X2gH7Vm1waiUon2SV780s3dgAq+XlCLQ14dB60+XhMu+27BcxVKdXOku56 JILvmbK4Ww2B2A6Gxsh3xGDOga8bouoNlP2mlQipEs2W+y6+xkrNgS7XoKT/EbPKKvGd/lCEnApcmDNSONt5KCQEWbpQGPLna9vgfb6rQ/dF6g9HMwJZh+nJ [email protected]
3. Configuration gitLab
  
  Go to Pofile Stting — SSH Keys — Add SSH Key and paste what you copied in the previous step into the text box corresponding to the Key
4. Upload a new folder to Git
  
  Open the command box, go to FDliucong, and set the username and mailbox
  
  Git config — global user.name
  
  Git config — global user.email “[email protected]”
  
  Then clone the project
```
git cloneSSH: / / [email protected]:222 / liucong/spring - the boot - 01 - helloword. GitCopy the code
```
  The address is from the following figure
  
  When completed, the project appears in the FDLIUcong folder
  
  But this is just an empty project, you need to copy the other code into the spring-boot-01-Helloword directory and upload it to Git by command, as shown below
  
  First go into the project directory,
  
  cd spring-boot-010helloword/
  
  You then add the project with the add command, essentially adding the file to the staging area
  
  Git add * (* means all files and directories) and commit the project
  
  Git commit — m
  
  Finally, push to Git with the push command
  
  git push origin master
  
  There it is on Git
5. The above is the code upload on GitLab. Of course, there is more than this way. The tool I use below is IDEA, which can be selected by myself

Jenkins installation and configuration

In order to distinguish, the projects are suffixed respectively to represent the code pulled from SVN and Gitlab
Click on the project to configure

The default master below is the branch name. I’m publishing the trunk by default, but I can also publish a branch
Click Build, as shown below

Building a successful
Jenkins script configuration, as well as server script

The configuration is basically the same as that of the SVN, but the server file directory is different. Therefore, the configuration must be changed

The server directory is as follows

The top is gitlab configuration, and the bottom is SVN configuration. In fact, the file content is the same

The Dockerfile and docker.sh files are the same as the files in the SVN directory above. Some changes need to be made to change the directory name and port
