set up the stable repository.
2. Get root access by entering sudo su –

3. Enter command yum install –y yum-utils
4. Enter command yum-config-manager
--add-repo
https://download.docker.com/linux/centos/docker-ce.repo
to add Docker repository

5. Enter command yum install docker-ce docker-ce-cli containerd.io to install latest
version of docker-ce. If it does not work, try installing docker-ce with specific
version.

2. Install specific version of Docker-ce
1. Enter command yum list docker-ce –showduplicates | sort –r to show the
available versions of docker-ce repos and sort according to version in
descending order.
2. Enter command yum install docker-ce-18.09.0-3.el7 docker-ce-cli-18.09.0-3.el7
containerd.io with specific version of docker-ce from the list. Here I choose
3:18.09.0-3.el7 from the list. If still error in installing docker-ce try entering
command yum –y remove podman and enter the command yum install docker-
ce-18.09.0-3.el7 docker-ce-cli-18.09.0-3.el7 containerd.io once again.

3. Enter systemctl start docker to start Docker and enter docker run hello-world to
check to verify Docker engine installed correctly.

4. Install Jenkins Docker Image in
Docker container
1. Login as root user and create a directory with name docker.
2. Enter command docker pull Jenkins

3. Run command docker run -p 8080:8080 -p 50000:50000 –v
jenkins_home:/var/jenkins_home jenkins/jenkins:lts and copy the secret key and
paste somewhere as shown in the figure below which is required while Jenkins run
first time.
4. Run command ifconfig to check new docker container is created or not.
5. Run Jenkins in browser by putting host computer IP address followed by :8080 Ex.
192.168.0.32:8080 in my case.
6. Jenkins request for the secret key, which was saved previously.

7. Create admin username and password

8. Now Jenkins is successfully configured and ready to use.
9. Successfully logged in to Jenkins dashboard and ready to build our software
projects.

5. Install Jenkins with Docker
Compose
Docker compose is a tool to run multi-container Docker applications by defining and
configuring our application’s service in a single YAML file. We can easily create and run
the services in a single command.
1. Run command curl -L
"https://github.com/docker/compose/releases/download/1.26.0/docker-compose-
$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose to install Docker
compose.
2. Apply executable permissions to the binary by running command chmod +x
/usr/local/bin/docker-compose
3. Make a directory and create a docker-compose.yml file. In my case directory is
/Jenkins
4. Open YAML file from WinSCP in an editor to edit file.

5. Copy the following configuration for Jenkins in YAML file. List of application’s
services should be listed under services as shown below.
6. Change the permission for the folder Jenkins so that every can modify. Command:
chmod –R 777 jenkins
7. Change the security context by running command chcon -Rt svirt_sandbox_file_t
/docker/software-factory/Jenkins
8. Run command docker-compose up Jenkins and Jenkins will start successfully.

Now the configuration files and folders are created inside /Jenkins folder as shown in
figure below.
Now you can run Jenkins and do all the starting setups gradually as stated in chapter 4
Install Jenkins Docker Image in Docker container above.
Fixing the error: java.net.UnknownHostException:
updates.jenkins.io
1. Opening the bash of the container where we are running the Jenkins service.
Run command docker-compose exec –u0 jenkins bash to execute bash

Run following commands:
# Masquerading allows for docker ingress and egress (this is the juicy bit)
firewall-cmd --zone=public --add-masquerade --permanent
# Specifically allow incoming traffic on port 80/443 (nothing new here)
firewall-cmd --zone=public --add-port=80/tcp
firewall-cmd --zone=public --add-port=443/tcp
# Reload firewall to apply permanent rules
firewall-cmd –reload
Once all the command runs successfully now we are able to see all the plugins from
online as shown in picture below.

7. Nexus
Nexus is a repository manager provided by Sonatype which allows to manage our
dependencies JARs throughout the organization among other developers. It also allows
our build projects to publish artifacts within the company internally. It works like Maven
Repository. We can be able to share our build projects as a component to other projects
as dependency. The following steps I went through to install and run Nexus in my Docker
container.
1. Installing Nexus
1. Go to hub.docker.com and search for “sonatype/nexus” choose the latest
version of sonatype/nexus i.e. sonatype/nexus3.

2. Add nexus service configuration in docker-compose.yml file
3. Make directory name /nexus in the /docker/software-factory and change the
permission for nexus folder by running command chown –R 200 nexus in the
putty console.
4. Now run the command docker-compose up nexus to run the nexus service.
There is no nexus installed so at first docker-compose will install the
sonatype/nexus3 in the container.

2. Creating user account in Nexus
1. Login with default username and password given in docker/software-
factory/nexus/admin.password file.
2. Go to setting part and create new local user.
3. Create new nexus roles for user and assign it to the created user.

4. Updating the maven settings.xml file which is located in docker/software-
factory/jenkins/tools/hudson.tasks.Maven_MavenInstallation/default/conf/settings.
xml
5. Create new server and assign username and password created in nexus.

8. Adding Sonarqube in
container
1. Open docker-compose.yml file and add sonarqube service in the file
sonarqube:
image: "sonarqube"
ports:
- "9000:9000"
volumes:
- ./sonarqube/data:/opt/sonarqube/data
2. Run command docker-compose up sonarqube to install sonarqube in the container.
Go to host IP address followed by port 9000 to open sonarqube page. Ex:
192.168.0.33:9000

9. Sonarqube in Jenkins
1. Select the project from Jenkins dashboard and go to configuration page.

2. Go to build tab and write the command -Dsonar.host.url=http://sonarqube:9000
clean install sonar:sonar
3. Now we can build the project again. This time if the is executed in sonarqube for
testing code with rules provided by sonarqube.

4. Open sonarqube in the browser with IP address followed by port.
Ex. 192.169.0.33:9000
5. We can see the results in the projects page of sonarqube.

10. Jenkins with Nexus
1. To deploy the maven project in nexus we write the following command in project
configuration page.
-DaltDeploymentRepository=deploymentRepo::default::http://nexus:8081
repository/maven-snapshots/ clean deploy
Here I insert new command in the above command which is –DskipTests=true –fn
so the full command is -
DaltDeploymentRepository=deploymentRepo::default::http://nexus:8081
repository/maven-snapshots/ –DskipTests=true –fn clean deploy.
It is because there was error in my test case of my project so it was making
difficulty while deploying so I put test-skipping command along with the
deployment command to ignore run tests.

2. Start Jenkins service and Nexus service.
docker-compose start Jenkins
docker-compose start nexus
I could not run all three services at once because of high consumption of memory,
my PC was not working well. That is way I ran only two services and did little
change in goal options rather than pushing to sonarqube for checking code quality.
I have done in the previous chapter with sonarqube separately.
3. After that when we build project, the project will create the jar file and deploy to
the Nexus repository when the build is success.
After successful deployment, it will be available in nexus repositories.

11. Gitea Installation
1. Set gitea service setup configuration in docker-compose.yml file.
2. Create service in the docker container by running command docker-compose up
gitea

The error is due to port mapping because some service is already using port 22 so I have
to change the port to 1022.
Run docker-compose up gitea again.

Now the gitea will be added in our host machine as shown in figure below:

Open gitea in browser your host ip address followed by port 3000. Ex 192.168.0.33:3000
Setting configuration for gitea for the first time.

Administration user setting and install gitea.
Gitea Dashboard page.

Creating new organization in gitea.
New Organization created.

Creating new repo as my-repo

12. Pushing project in gitea
repository
1. Create new maven project in eclipse to push in the gitea repository. I have created
a demo project to push in gitea. i.e. gitea-demo
2. Commit the project and push our project to the gitea repository link.
Right click in project > team > share project
3. Create new repository in the local machine.

4. Commit project
5. Add gitea repository

The project is pushed to gitea repository.

13. Adding gitea as source code
management in Jenkins
1. Create new maven project in Jenkins i.e gitea-project
2. Add the gitea repository link in the source code management field in project
configuration.

2. Build project in Jenkins
After build success
