In this tutorial, you will come to know about what is Ansible, Docker and what is the need of launching a Docker with Ansible, in which cases you can use this tools. Ansible is an open-source software provisioning, configuration management, and application-deployment tool enabling infrastructure as code. Docker is a set of platform as a service products that use OS-level virtualization to deliver software in packages called containers. In simple terms it is a light weight virtualization.
In this blog you will come to know about what is Ansible, Docker and what is the need of launching a docker with ansible, in which cases you can use this tools. If you are reading this blog then you have heard this terms earlier. No problem I will discuss eveything here.
Ansible is an open-source software provisioning, configuration management, and application-deployment tool enabling infrastructure as code. It runs on many Unix-like systems, and can configure both Unix-like systems as well as Microsoft Windows.
In simple terms it is a Automation tool. It is useful when you want to configure 2 or more number of systems. You think that we can also do this automation with a programming language like python, R, scala, java …etc.
But that languages should know what to do and how to do?
In ansible we only say what to do? It is declarative type of language. It doesn’t have any personal language. It uses YAML for writing the tasks.
Ansible has a feature called playbook where we can write a group of tasks and can be easily executed on the remote server or node.
Docker is a set of platform as a service products that use OS-level virtualization to deliver software in packages called containers. In simple terms it is a light weight virtualization.
Docker is easy to carry and can run in different environments with out crashing the application as it contains all the dependencies.
If we want our application to run continuously in different environments we have to configure the docker. As there is also a requirement for installing and configuring the software inside the docker.
Steps involved in configuring a docker with a webserver installed in it.
At some point we've all said the words, "But it works on my machine." It usually happens during testing or when you're trying to get a new project set up. Sometimes it happens when you pull down changes from an updated branch.
The docker manifest command does not work independently to perform any action. In order to work with the docker manifest or manifest list, we use sub-commands along with it. This manifest sub-command can enable us to interact with the image manifests. Furthermore, it also gives information about the OS and the architecture, that a particular image was built for. The image manifest provides a configuration and a set of layers for a container image. This is an experimenta
Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub.
Understanding DevOps and key differences between Ansible, Docker and Kubernetes. There are many DevOps tools one can use for automation processes like Pepper, Chef, Terraform, and more. But the forerunners are Ansible, Docker, and Kubernetes.
This article talks about the recent partnership between Docker and JFrog and how this partnership impacts developers and enterprises positively? The whole DevOps world works involving containers in building, packaging, running and shipping their software applications.
