Sﾃｳlo soporta arquitecturas de 64 bits, ademﾃ｡s de que requiere una versiﾃｳn de Kernel de al menos 3.8. Por lo general, no se pueden extraer muchas malas conclusiones sobre Docker.

Una de las caracterﾃｭsticas que mﾃ｡s me gustan de Docker es que una plataforma de cﾃｳdigo abierto. Entre las principales ventajas de esta plataforma es obligatorio destacar la forma en la que aﾃｭsla las aplicaciones y sus requisitos, de modo que sus instancias se inician rﾃ｡pidamente y son muy portables. Permite emplear por ejemplo sistemas operativos distintos, o versiones distintas del entorno de ejecuciﾃｳn de las aplicaciones segﾃｺn las dependencias de estas, pudiendo ejecutarse todas estas aplicaciones en un mismo host sin causar conflictos. La administraciﾃｳn de los contenedores y de sus capas es sencilla, y agiliza los tiempos de despliegue de cualquier proyecto empleando mﾃ｡quinas virtuales muy ligeras. Otra ventaja es que consume muy pocos recursos hardware. Por ﾃｺltimo, destacar que el uso de los Dockerfiles es muy ﾃｺtil e intuitivo a la hora de construir contenedores personalizados.

Recomiendo Docker para desarrolladores o administradores de sistemas cuyas aplicaciones o despliegues tengan ciertas dependencias, o bien en el caso donde se estﾃｩ virtualizando con mﾃｩtodos menos portables o que no aﾃｭslen el despliegue de las aplicaciones.

You need to create docker image from your code, even if your code have a single line of change, whole image needs to be rebuild.

Docker is an amazing tool, if you want a highly scalable application. It encapsulates your code into docker images which can run on any linux system kernal. You do not need to worry about your environment, as environment is contained in the docker image itself. Great if you have applications whose environment can interfere with each other. For example, one of your applications uses java 7, while the other one uses java 8. You can run both application on a single system by having separate images for both.

What do you dislike?

The software must fight for system resources, so sometimes the bottleneck is not the disk, CPU, network.. etc. They are the system resources, and that's hard to stop. I also don't like the awkward process of writing a Dockerfile. I think it should have done it easier, there are too many options with many subtle differences

What do you like best?

The easiness to download Dockerfiles, and to run them. DockerHub is a great place to find containers also. I like that the process separation is via cgroups, so it is not that heavyweight as virtual machines. I also like the integration with Ansible, so the build process is just an "Enter" away.

There's almost no rivalry to Docker, so better to learn it if you're doing DevOps!

What do you dislike?

Although Docker provides a way of containerization, it does not give a great way of orchestrating them. We do have an option of using Docker Swarm but it has a very high costing plus it does not have monitoring feature internally. We need to rely on external monitoring tools and pay for them as well while tools like Kubernetes have Docker support, does container orchestration and provide monitoring through Grafana as well.

Docker is one of the best containerization tool out there. It has a great feature of creating platform independent software VMs that run as a container and uses internal kernel features namespace, resource isolation, cgroups, etc. All these can be accomplished by building images using simple to write and read Dockerfiles.

What do you dislike?

Sometimes i find difficult to open a docker container, may be due to some background issues.To start Docker Containers, it don't have comprehensive guidelines and therefore different containers may take different skills to implement.One thing which i dislike the most is that the containers share the same kernel and is less isolated than VMs.

What do you like best?

Docker is safer to deploy with a consistent container system. With just a single command, i set up Php and Nginx with Docker.The best part of it is, its simplicity.It is quite better than using a virtual machine in virtualBox because it is extremely configurable.Docker works on any device allowing all employees to make their own preferences for better productivity.

It is very useful and having a huge variety of apps that are ready to be deployed on your local machine.But taking some time to properly use it, is very important part.
