Whether you are new to the cloud or devops, you have undoubtedly heard about Docker. If you are designing an app for business or education, it may be a good idea to check out the template below, even if you are just getting started with virtualization or the LXC platform. Listed below are the top 15 Docker containers currently available.
1. Alpine
Compared to previous BusyBox-based images, the image has access to a package repository that is significantly more comprehensive. For production apps and utilities, Alpine Linux is a fantastic image basis. It is a basic Alpine Linux image with a package index. It is only 5 MB in size and was created using BusyBox and the Musl libc.
2. BusyBox
In order to create distributions that take up little space, BusyBox is a great element. BusyBox is a compact program that combines a number of popular UNIX functions. The utilities have fewer choices than full-featured GNU, but the ones that are there still operate and behave similarly to their GNU equivalents. As a result, BusyBox gives any small or embedded system a pretty full environment.
3. Nginx
A load balancer, origin server, and reverse proxy server all in one, Nginx is free software. It functions on various versions of *nix, including Linux, BSD, Mac OS X, Solaris, AIX, HP-UX, and Solaris. Moreover, it features a proof-of-concept version for Windows.
4. Ubuntu
The most often used operating system worldwide for OpenStack and public clouds is Ubuntu. The container platform can also operate your containers rapidly and safely at scale.
5. Python
Python uses classes, dynamic typing, high-level data types, errors, and modules. Additionally, it serves as an extension language for programs that require customizable user interfaces. It can operate on many Unix variants, including Mac and Windows 2000 and later, and is portable. You may need assistance creating a comprehensive Dockerfile for many straightforward, single-file tasks. In these circumstances, you can execute a Python application using the Python Docker image.
6. PostGreSQL
PostgreSQL, also known as “Postgres,” manages tasks for single-machine apps as well as web-based programs with numerous users. Numerous environment variables are used in the picture and are simple to overlook. Only POSTGRES_PASSWORD is necessary; all other variables are discretionary.
7. Redis
Redis is a networked data storage that is open-source and offers optional durability.
The “Protected mode” is by default disabled to allow for simple access via Docker networking. As a result, anyone can access the port without a password if you reveal it to the outside world (for example, using the -p flag on docker run). Therefore, it is strongly advised to establish a password (by providing a config file).
8. Apache httpd
Apache is a Web server program that was crucial to the early development of the internet. Only the upstream settings for Apache httpd are included in this image. There isn’t any PHP loaded, but it should be simple to expand. On the other hand, view the PHP file and pay attention to the -apache tags if you want PHP with Apache httpd.
Add a Dockerfile to the project with public-HTML/ as the directory containing all the HTML to start an HTML server.
9. Node
A platform for server-side and networking apps is Node.js. On Mac OS X, Windows, and Linux, Javascript applications can operate unchanged within the Node.js runtime. Asynchronous I/O libraries for file, socket, and HTTP transmission are already included with Node.js. Node.js can function as a web server without the need for extra software like Apache thanks to the HTTP and socket support.
10. MongoDB
An open-source database tool called MongoDB makes use of documents that resemble JSON and have schemas. The MongoDB server in the image connects via Docker networks and operates on the default MongoDB port, 27017, just like a remote mongod.
11. MySQL
Since it can be used for many types of websites and personal projects, MySQL has emerged as a top database for web-based applications.
It’s easy to launch a MySQL instance:
$ docker run –name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag12. MariaDB
Popular open-source database server MariaDB Server was created by MySQL programmers. With the most recent version, starting a MariaDB instance is straightforward:
$ docker run –detach –name some-mariadb –env MARIADB_USER=example-user –env MARIADB_PASSWORD=my_cool_secret –env MARIADB_ROOT_PASSWORD=my-secret-pw mariadb:latest
or:
$ docker network create some-network
$ docker run –detach –network some-network –name some-mariadb –env MARIADB_USER=example-user –env MA13. RabbitMQ
The Advanced Message Queuing Protocol is implemented by the free and open-source message broker program RabbitMQ. The “Node Name,” which is always the hostname, is used to store data. So that the user doesn’t receive a random hostname and can keep track of the data, we should explicitly specify -h/-hostname for each daemon when using Docker.
14. Traefik
An HTTP reverse proxy and load balancer called Traefik makes the deployment of microservices simple. It dynamically configures itself and automatically interacts with the current Docker infrastructure. The single configuration step should be to point Traefik at your orchestrator.
15. Memcached
A distributed memory caching system is Memcached. Its APIs offer a sizable hash table spread over numerous machines. When the table is full, older data is deleted in the order of least recent use. Applications using Memcached typically layer requests and adds into RAM before quitting on a slower backing store.
