What do you dislike?

My only issue with docker is that persistent data storage is very complicated since when a container shuts down all that information is gone unless you figure out with docker data volumes which are not easy to work with.

Containers are the place where companies should move and Docker makes it easy, Docker works on any device that needs it, to allow all employees to use the machine that best promotes their creativity and productivity according to their preferences. I love how easy it is to set up a virtual machine, add one and also get rid of it. The principle of pulling virtual machines away if they are no longer needed and building them when necessary is a delight, you can also create your own images based on those of one or more available in the hub. You can also create your private center to store private images of your software.

Recommendations to others considering the product

We recommend docker as a service to grow your business.

What do you dislike?

Slow if you try to run Docker inside a VM. Probably an unusual use-case, but some dev actually do development in VM.

What do you like best?

It allowed me to create a server without spawning a full VM (which, for development purpose is very heavy) - what's not to like about that?

Recommendations to others considering the product

The only time you need to re-consider using this is if your dev is developing inside VM with different kernels (example: Windows VM inside Linux host), it's very slow during startup. By slow, I mean like 10-15 mins startup time which is horribly slow.

What do you dislike?

Running any virtual technologies can sometimes be a resource hog. Higher end more expensive hardware is preferred to run virtualized containers than running the software natively.

What do you like best?

Quick and easy deployment of required developer software.

What do you dislike?

Trying to handle and get multiple docker containers to talk to each other is definitely a challenge and requires a bit of a learning curve. Docker environments are not perfect replicas of actual linux servers, since they provide their own type of architecture, but luckily it's close enough to where it can be useful.

What do you like best?

Docker allows for a customizable container for any type of application/microservice service/etc. I have used other virtualization tools before, such as VMWare, Vagrant, and none of them have been as easy to set up or easy to use.

What do you dislike?

There is no good docker / kubernetes hosting supporting DSGVO at the moment

What do you like best?

Isolated testing environments and seamless deployment of complex applications

What do you dislike?

difficult to set up a private repository to use. can be slow at times

What do you like best?

easy to use and very good documentation. Easy ramp up period. Images are lightweight

What do you dislike?

So far it has worked and we don't report any issues.

What do you like best?

it has allowed us to scale our web application while not having the complexity of the parts of our software product slow down the development and deployment of new features and product expansion.

What do you dislike?

I don't like that sometimes programs are out of date and sometimes, I cannot open a Docker container due to some background issue. Also, it did take a me a bit to learn how Docker worked, but I learned fairly quickly. Mainly, though, I dislike that I didn't know about Docker sooner.

What do you like best?

I like that there are plenty of Docker images and that I do not have to install a bunch of programs to run a program, especially if I just want to try it out. I use a lot of programs for genomic assembly and analysis. Docker allows me to save some space on my computing cluster by only using a program as needed rather than installing it and consuming valuable space.

What do you dislike?

Docker container is not standalone, means you can't run it instead of an OS.

What do you like best?

Docker is extremely configurable and performs better than a virtual machine. Virtual machine has their own memory management, thus possess extreme overhead on the host system. While the Docker container runs as an application, could be started in few seconds and the applications in the container perform same as the virtual machine

Recommendations to others considering the product

Just use it. It's easy to setup. In my case, I have a shell script prepared by another developer which I run to deploy the application. So no hassle for me.
