Docker - How to create your own Blog/WebApp/Web site?

Let's convert lockdown days into Learning days and today's learning is :-

1. Started with what is Wordpress, what is it and how it work?
2. Created a architecture of how I can create my own blog?
For this I need WordPress and MySQL two docker images so lets pull them from docker hub and start with implementation.
[root@server109 ~]# docker pull wordpress:5.1.1-php7.3-apache
[root@server109 ~]# docker pull mysql:5.7

3. Created two storage in docker one for mysql and another is for WordPress container
[root@server109 ~]# docker volume create mywp-storage
mywp-storage
[root@server109 ~]# docker volume create mysql-storage
mysql-storage

4. Launch a MySQL container with environment variable (-e option) database, username, customized storage(created previously
[root@server109 ~]# docker container run -dit -e MYSQL_ROOT_PASSWORD=redhat -e MYSQL_USER=rakesh -e MYSQL_PASSWORD=redhat -e MYSQL_DATABASE=mydb  -v mysql-storage:/var/lib/mysql --name  mysql_container mysql:5.7

 5. Launch another container and here I used mysql container created above
[root@server109 ~]# docker container run -dit -e WORDPRESS_DB_HOST=mysql_container -e WORDPRESS_DB_USER=rakesh -e WORDPRESS_DB_PASSWORD=redhat -e WORDPRESS_DB_NAME=mydb -v mywp-storage:/var/www/html --name mywp_container -p 8080:80 --link mysql_container wordpress:5.1.1-php7.3-apache

6. One interesting think I have done in this which that I have exposed WordPress container(PAT -p 8080:80) so that I can access my web app anywhere in my network and if I use public IP then it will be accessible from anywhere using internet.

7. Things are working fine but it was a manual process. So to automate I'll move on Docker-Compose. It is infrastructure-as-code for docker.

8. Created an infrastructure using docker-compose
[root@server109 ~]# mkdir /mydocker-workspace
[root@server109 ~]# cd /mydocker-workspace
[root@server109 ~]# vim docker-compose.yml

Please check below for docker-compose file content
Note:- Format(Indentation) is very mandatory
[root@server109 mydocker-workspace]# cat docker-compose.yml
version: '3'
services:
        mysql_container:
                image: mysql:5.7
                volumes:
                        - mysql-storage-new:/var/lib/myswql
                restart: always
                environment:
                        MYSQL_ROOT_PASSWORD: redhat
                        MYSQL_USER: rakesh
                        MYSQL_PASSWORD: redhat
                        MYSQL_DATABASE: mydb

         mywp_container:
                image: wordpress:5.1.1-php7.3-apache
                volumes:
                        - mywp-storage-new:/var/www/html
                restart: always
                depends_on:
                        - mysql_container
                ports:
                        - 8081:80
                environment:
                        WORDPRESS_DB_HOST: mysql_container
                        WORDPRESS_DB_USER: rakesh
                        WORDPRESS_DB_PASSWORD: redhat
                        WORDPRESS_DB_NAME: mydb
volumes:
        mysql-storage-new:
        mywp-storage-new:

Failed to get D-Bus connection: Operation not permitted

" Failed to get D-Bus connection: Operation not permitted " - systemctl command is not working in Docker container. If systemctl command is not working in your container and giving subjected error message then simple solution of this error is, create container with -- privileged option and also provide init file full path  /usr/sbin/init [root@server109 ~]# docker container run -dit --privileged --name systemctl_not_working_centos1 centos:7 /usr/sbin/init For detailed explanation and understanding I am writing more about it, please have look below. If we have a daemon based program(httpd, sshd, jenkins, docker etc.) running inside a container and we would like to start/stop or check status of daemon inside docker then it becomes difficult for us to perform such operations , because by default systemctl and service  commands don't work inside docker. Normally we run below commands to check services status in Linux systems. [root@server109 ~]# systemctl status

AWS cloud automation using Terraform

In this post I'll create multiple resources in AWS cloud using Terraform . Terraform is an infrastructure as code( IAC ) software which can do lots of things but it is superb in cloud automation. To use Terraform we have write code in a high-level configuration language known as Hashicorp Configuration Language , optionally we can write code in JSON as well. I'll create below service using Terraform- 1. Create the key-pair and security group which allow inbound traffic on port 80 and 22 2. Launch EC2 instance. 3. To create EC2 instance use same key and security group which created in step 1 4. Launch Volume(EBS) and mount this volume into /var/www/html directory 5. Upload index.php file and an image on GitHub repository 6. Clone GitHub repository into /var/www/html 7. Create S3 bucket, copy images from GitHub repo into it and set permission to public readable 8 Create a CloudFront use S3 bucket(which contains images) and use the CloudFront URL to update code in /var/w
