Ansible Installation

1) Create RedHat 3 Servers (1-AnsibleServer , 2- Host Machines for demo) in AWS.

2) Login As a root user and create ansible user and provide sudo access in all Servers.

    2.1) Create the user ansible and set the password on all hosts:
           sudo useradd ansible
           sudo passwd ansible

    2.2) Make the necessary entry in sudoers file /etc/sudoersfor ansible
           user for password-less sudo access:

visudo

           ansible ALL=(ALL) NOPASSWD: ALL



    2.3) Make the necessary changes in sshd_config file /etc/ssh/sshd_config
           to enable password based authentication.

         Un comment PasswordAuthentication yes
        and comment PasswordAuthentication no.
         And save the file .

            vi /etc/ssh/sshd_config

                sudo service sshd restart

=============================================================================
               Install Ansible in Red hat (Ansible Server)
=============================================================================

1)    SSH to Redhat System & Switch to ansible user
       sudo su - ansible

2)    Install python
       sudo yum install python3 -y

3)    Update python alaternatives
       sudo alternatives --set python /usr/bin/python3

4)    Verify Python Version
     python --version

5) Install ansible using Yum

sudo yum -y install ansible

6)    Verify Ansible version
       ansible --version

=============================================================================
Generate SSH Key, Copy SSH Key(Ansible Server)
=============================================================================

1) Now generate SSH key in Ansible Server:

sudo su - ansible

ssh-keygen

2) Copy it to Host servers as ansible user:

Repeat below command by updating HOST IP for all the HOST Servers.

ssh-copy-id ansible@<HostIP>

Update Host Inventory in Ansible Server to add host servers’ details.

1) Add Host Server details

vi /etc/ansible/hosts

# Connect using username and password

192.168.1.105 ansible_user=ansible ansible_password=password

# Connect using username and pem(Make Sure Have pem file at given path)

172.31.35.23 ansible_user=ec2-user ansible_ssh_private_key_file=~/aws.pem

# If ssh keys are copied

172.31.35.23

2) Use ping module to test Ansible and after successful run you can see the below output.

ansible all -m ping

172.31.35.23 | SUCCESS => {

"changed": false,

"ping": "pong"

}

3) Install sshpass in Ansible server if you get below error .

"to use the 'ssh' connection type with passwords, you must install the sshpass program

$ sudo yum install -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/sshpass-1.06-2.el7.x86_64.rpm

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
