Install Docker Offline on Centos7

Recently, I had to build an environment which have a kind of real web application running to test LBaaS site affinity solution,. After a few minutes,I made a decision to install a Jenkins container on my testing Centos 7 virtual machines. 

Unfortunately, my Centos virtual machines have no Internet access. So I spent a bit of time to work out how to installl docker and run a container offline on Centos 7. Then I have this blog which maybe can help others who have the same challenge.

The docker version which I am going to install is: 
docker-ce-18.03.1.ce-1.el7.centos

On another Linux Centos 7 (minimum install) which have Internet access, I run the CLI below to identify all required packages for Docker offline installation.
repoquery -R docker-ce-18.03.1.ce-1.el7.centos
From the output, I found out that I need the following packages to complete Docker offline installation:

1:libsepol-2.5-8.1.el7
2:libselinux-2.5-12.el7
3:audit-libs-2.8.1-3.el7_5.1
4:libsemanage-2.5-11.el7
5:libselinux-utils-2.5-12.el7
6:policycoreutils-2.5-22.el7
7:selinux-policy-3.13.1-192.el7
8:libcgroup-0.41-15.el7
9:selinux-policy-targeted-3.13.1-19
10:libsemanage-python-2.5-11.el7
11:audit-libs-python-2.8.1-3.el7_5.1
12:setools-libs-3.3.8-2.el7
13:python-IPy-0.75-6.el7
14:pigz-2.3.3-1.el7.centos
15:checkpolicy-2.5-6.el7
16:policycoreutils-python-2.5-22.el7
17:container-selinux-2:2.68-1.el7
18:docker-ce-18.03.1.ce-1.el7.centos
19:audit-2.8.1-3.el7_5.1

Then I went to download docker rpm package and all dependent packages with yumdownloader:
yumdownloader –resolve  docker-ce-18.03.1.ce-1.el7.centos

I archived the above packages (tar cf docker-ce.offline.tar *.rpm) and uploaded to my offline Centos 7 virtual machines. Then use the rpm CLI to install Docker:

[root@lbaas02 ~]# rpm -ivh –replacefiles –replacepkgs *.rpm

After the installation completed,  started and enabled docker service:

[root@lbaas02 ~]# systemctl enable docker

Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

[root@lbaas02 ~]# systemctl start docker

Now the next question for me is to import the offline Jenkins docker image. Firstly, I pulled the Jenkisn docker image:

docker pull jenkins/jenkins

Then exported the docker image as a file and uploaded to my testing Centos.

docker save -o jenkins.docker jenkins/jenkins

On my testing Centos, I loaded the image to docker process.

[root@lbaas01 ~]# docker load -i jenkins.docker

Now I am able to start my Jenkins docker on this offline Centos 7.

docker run -d -p 8080:8080 -p 50000:50000 -v jenkins_home:/var/jenkins_home jenkins/jenkins

Wait for 2-3 mins. After Jenkins container is fully running, I can login into my Jenkins.:)
