PUSH/PULL Docker Image form Private Repository (Nexus) - Mithun Technologies +91-9980923226

PUSH/PULL Docker Image form Private Repository (Nexus)

Pre-Requisities:

Server 1: Ubuntu                                         Server 2: Ubuntu

Install the below softwares in Server1          Install the below softwares in Server2

Java 8                                                              Docker

Docker

Jenkins

Maven/Gradle

Server 1:

1   We are going to build our project using maven/gradle

2   Through docker file we are going to create an docker image for that project

3   We are going to push the docker image to Nexus (docker hosted) repo

Server 2:

1  We are going to pull the docker image form Nexus (docker hosted) repo

2   Create a container using the docker image

Nexus Repository (docker hosted,proxy) Creation:

docker hosted:   

1) Login to your Nexus repository.

2) Create docker hosted

 

 Here give a name to the repo (dock-hosted), then we are going to assign a port to this docker hosted repo. Through this port we are going to access this repo. (Note: you should not give 8081 because it is already assigned to Nexus Repo, so use different port number)

In this case I have assigned 8083 for this repo.

3) Keep the remaining settings as it is and create repository

 Note: Open 8083 in AWS Security Groups.

Ubuntu Configuration : Server 1 & 2

Do these steps in both the servers in order to push and pull docker images from Nexus Repo.

1.     Login as root user

2.     Go to /etc/docker

            cd /etc/docker

3.     Then create a file called daemon.json

vi /etc/docker/daemon.json

4.     Write these script in daemon.json

{

  "insecure-registries": [ "13.234.21.143:8083" ]

}

(Here we are allowing our docker daemon to access the Nexus Hosted Repo)

5.     Save the file

6.     Restart docker service using below command.

            systemctl restart docker

 

Server 1: Login,Build & Push

1 Login to Nexus repo

docker login –u admin –p password 13.234.21.143:8083

(or)

docker login 13.234.21.143:8083

2  Build an image using below command.

docker build –t 13.234.21.143:8083/image1 .

           

(here while building an docker image we will use ip address with port for the docked hosted repo instead of username in hub.docker.com)

 

3 Push docker image to Nexus Repo

Server 2: Pull image/Run container

1.     Login to Nexus

2   Pull docker image

 

3  Build a container

docker run –d –p 8090:8080 –p 9990:9990 - -name wildfly 13.234.21.143:8083/image1

(I am using wildfly to deploy)
