Install Docker Swarm Cluster on Debian 10 -Step by Step Process ?
This article covers how to install Docker Swarm Cluster on Debian 10. Docker Swarm is a tool used to orchestrate docker hosts. We can create a high availability and a high performance Docker cluster with applications distributed among the hosts. Docker swam uses a manager host and worker nodes architecture. You can have one or several manager nodes in your docker swarm cluster. The manager nodes uses the native Docker API and share the database of the Docker Swarm cluster with the worker nodes. The manager hosts maintain the cluster state, schedule tasks and handle the HTTP API endpoints.
Install Drupal with Docker Compose
This article covers how to install Drupal with Docker Compose. Basically, installation process of Drupal can be simplified with the use of tools like Docker and Docker Compose. Docker Compose can be used to create a Drupal installation with an Nginx web server.
Drupal and Docker needs the following to work:
1. HTTP Server with PHP: We can either use Apache with PHP or Nginx with PHP. I'm going to demonstrate building the Docker using Apache with PHP. A Drupal docker can also have services like SSH (for drush alias to work) and some important utilities like vim
2. SQL Server: Choose your favourite SQL Service (MySQL or PostGRESQL or SQLite). I'm going to be using a MySQL docker. The idea behind using a separate docker for SQL is so that you have a freedom to choose an internal SQL service or an external SQL Services like Amazon RDS without affecting your Drupal environment.
The need to Use Docker to Run Drupal:
Using the Drupal and PostgreSQL images from Docker Hub offers the following benefits:
1. The configuration of the software has been done for you, which means that you don’t need to follow a step-by-step process for each application to get them running on your system.
2. Updating your software is as simple as downloading the latest images from Docker Hub.
3. Images and containers are self-contained, which means that they are easy to clean up if you decide to remove them.
How to Set Up Drupal ?
1. Create a new directory in your home folder called my_drupal and cd into it:
mkdir ~/my_drupal/
cd ~/my_drupal/
2. Create a file named docker-compose.yml in this folder and add the following contents. Set your own password for the POSTGRES_PASSWORD option.
3. From the my_drupal directory, start your Docker containers:
docker-compose up -d
4. The Docker containers will take a minute or two to start up Drupal and PostgreSQL. Afterwards, you can visit your Linode’s IP address in your web browser .
5. On the Set up database page, select PostgreSQL as the Database type and enter the following values:
Database name: postgres
Database username: postgres
Database password: The password you set in the docker-compose.yml file
Host (under Advanced Options): postgres
6. When creating your Drupal user, be sure to enter a password that is different from your PostgreSQL password.
Jenkins setup with Docker and JCasC - Automate it now
This article covers how to perform Jenkins Configuration as Code (JCasC) method which can help us to automate the setup of Jenkins using Docker.
This will automate the installation and configuration of Jenkins using Docker and the Jenkins Configuration as Code (JCasC) method.
Jenkins uses a pluggable architecture to provide most of its functionality.
JCasC makes use of the Configuration as Code plugin, which allows you to define the desired state of your Jenkins configuration as one or more YAML file(s), eliminating the need for the setup wizard.
On initialization, the Configuration as Code plugin would configure Jenkins according to the configuration file(s), greatly reducing the configuration time and eliminating human errors.
Just as the Pipeline plugin enables developers to define their jobs inside a Jenkinsfile, the Configuration as Code plugin enables administrators to define the Jenkins configuration inside a YAML file.
Both of these plugins bring Jenkins closer aligned with the Everything as Code (EaC) paradigm.
How to Provision docker containers with Ansible
This article will guide you on how to provision docker #containers using Ansible. #Ansible seamlessly automates #Docker and the process of building and deploying containers.
Ansible Container will allow users to build, #deploy, and orchestrate containers at scale, all from Ansible playbooks.
Set Up Laravel Nginx and MySQL with Docker Compose
This article will guide you on how to set up #Laravel, #Nginx, and #MySQL with #Docker Compose. When using a #LEMP application stack, for example, with PHP, Nginx, MySQL and the Laravel framework, Docker can significantly streamline the setup process.
Docker Compose has further simplified the development process by allowing developers to define their #infrastructure, including application services, #networks, and volumes, in a single file. Docker Compose offers an efficient alternative to running multiple docker container create and docker container run #commands.
