Opiniones de Docker

Docker has proven to be a fairly efficient and stable virtualization platform for productive environments of high stress and traffic flow.

The compatibility with other work tools is almost 100% guaranteed and also allows testing and deployments at speeds never before reached by infrastructure departments. One of the most significant advantages is the large repository of images of applications that are available in the docker hub.

Without a doubt, of the best tools that I use in my day to day

It takes great knowledge of linux and infrastructure to use docker, it is not a tool for beginners, if you do not have the basic knowledge of a LAMP or LEMP for example, you can not deploy a disconnected application in docker, much less create base clusters of data, among many other things.

The GUI helped me understand its all basic concept and functionality. The best thing about docker on windows is we can configure its system requirements easily without any hassle.

There is very less thing i could say because i haven't encountered in my learning phase. Though it took me a while to understand the .wslconfig file in windows.

Installing and configuring docker is very easy. Also, creating, pulling, and running docker containers are very easy. It makes it easy for a developer to containerize his application. Also, we get a lot of official images of mostly used software from Docker Hub.

Monitoring and Garbage clearance can be improved a lot. It becomes very hard for monitoring and analyzing docker containers. It can be improved a lot.

Implementing an IoT platform is quite easy, but deploying it and installing it in different environments can be quite challenging.Docker handles this pretty well. Running our image on different systems, pulling automatic updates with a tool such as watchtower, checking and executing updates makes our job much easier.

In terms of use, I did not have any difficulties with the visual interface or terminal commands, but I had a lot of problems with the installation on Windows, especially on the PCs provided by companies. The reason for this was WSL, then I solved the problem, but they can make improvements or more descriptive guide content in this area.

I find very convenient the way I can ship a demo by creating a docker image with all what is needed inside. I am more tended to the idea of a container serving a single purpose, but in much cases docker can be used to package and ship all that is needed to have a not complex MVP, even if it was complex several docker images can be built, but talking about simple cases I found docker easy of use by the final audience, they do not need to know all the details or have strong skills, just a few instructions and they are ready to see the demo. And also in some more complex cases, end users with more deep technical skills simply ask for a docker image with specific requirements, since they know how to connect the pieces and they have some infrastructure in place they can easily plug in the docker image.

IMO the user experience for a developer is more easy in linux based environments than in Mac environments, or it also could be that the development environment provided by some companies is some kind attached to mac computers but then on the testing, deployment, and production environments is more linux based. So the experience is not kind of uniform in my opinion.

1. Huge database for base images: Dockers works with Docker Hub by default which has a huge database of base images which includes Operating Systems with very limited tool set installed on top. This helps make the OS super light and can be downloaded and ran under minutes.
2. Any docker image runs as a container/ service which is independent from any other containers. However, each container can run in conjuction with other containers and they can even restart and be alive at all times automatically.
3. DockerFiles can be used to build docker images easily which can then be posted on DockerHub for private or public usage.

Docker lacks containerization due to which it is used only as the underlying software and not as a primary software. Containerization is a large part of microservices, therefore, this is one of the cons of docker. However, many third party orchestration tools are available for performing these activities.

Docker allows us to containerize our applications - meaning that pieces of big application can run in isolation, without having to set up dependencies on any environment. It allows us to worry less about server configuration, setup time on individual machines and not have to worry about dependency management. In conjunction with Kubernetes, it works great to deploy containerized applications to facilitate microservice/microfrontend architected applications

Docker has a steep learning curve. Configuring Docker desktop itself is a pain, although it becomes easier to containerize applications once the setup is complete. It requires a great deal of RAM , and thus, nearly impossible to work, on low RAM laptops.

Docker is the most popular container tool that helps teams set up and mange environments to run their applications without having to resort to VMs. It provides a simple interface to create environments and test, deploy and maintain applications within local, on-prem or cloud infrastructure. It has an extensive community that builds Docker images, pre-built environments that support for a variety of operating systems, programming languages and tools.

Docker can have a somewhat steep learning curve and is hard to explain to someone who doesn't know about it. Some of the more nuanced configuration options can be hard to find and harder to understand for newcomers. The support for Windows environments is also not as extensive as it could be.

Easy to use, great documentation, wide support in all major cloud providers and OSes (both regular and NAS oriented), lighter on resources than even the lightest VM. Great for web-specific microservice-oriented solutions deployments. Supported by all CI/CD platforms.

Security/privilege requirements of running the dockerd daemon.It's being dropped for CRI-O in Kubernetes deployments.

Docker is one of the best containerization application. To achieving continue integration it's very helpful. Managing the deployment container and images is now easy with Docker. Docker help to do the things for you by automation. Once you configure a Docker in your environment it will make sure that issue will not occur due to development or production environment. It also very helpful in deployment and virtualization. The best thing in it is secure and transparent as it's source code is open.

As docker can be configure in all environment and architecture, but it is sometime very challenging to solve the particular issue that is making hurdle in configuring it. Documentation is also limited as it is not covering all the aspects or environment in which we or our organization is working. I feel they should also provide the some enterprise feature like image management in open source version also.

The best thing about docker will be docker cloud. You can have your application in docker cloud and offer with your colleague or make it open which make it to a great degree accommodating to introduce your application in truly any framework without agonizing over the framework conditions. Heaps of supporters are there in docker cloud.

Not more documentation about various approaches to send application. Not great documentation about various directions you can keep running on docker-make and their conditions. Some time you feel stuck while taking care of specific issue and you discover no assistance in the web.

Docker is a very awesome tool to deploy containerized application. Docker is very helpfull while working in very big team. Docker make it very easy to deliver code or application as container. Docker makes environment setup very easy as it allows platform-dependency. Docker help to build, run any application anywhere .Using Docker we can create our images and we can push those images in Docker hub
using Docker we can run our application as a lightweight, portable, self-sufficient container anywhere.

One of the major issue I have faced with docker is, it is very difficult to run a Docker container build for windows on other operating system like Linux.
