What do you dislike?

Docker adds an additional layer of complexity to the build and deployment of an application.

What do you like best?

Docker creates a very easy way to run applications.

Recommendations to others considering the product

I would definitely recommend Docker to anyone that is interested. Docker is a great tool that provides great ease of use and can be used by all of the members within a team.

What do you dislike?

It takes a bit of time to build an initial docker image.

What do you like best?

It's easy to get started with Docker and set it up. It has quite a good documentation. It makes the deployment process easier and useful for DevOps to mimic the production environment.

Recommendations to others considering the product

It is useful when you need to do deployment to multiple servers or if you need to mimic the production environment for DevOps.

What do you dislike?

Local development can be a hassle with logs from all services being lumped into one giant stream on STDOUT. This isn't so much of a problem in production when connected to a mature logging service (we use SumoLogic) which allows easy querying, but it can make local debugging a bit messy.

What do you like best?

Containerization gives exceptional control over environment, which reduces bugs and unpredictable test results.

What do you dislike?

This is a product that is work in progress, additional functionalities are being added and numerous bugs that are annoying. Also, theres security concerns around containers and how to secure these containers. The code base still changes at a relatively quick pace compare to other more mature software products.

What do you like best?

Docker has provided freedom to setup, replicate, distribute our work environments and deployment environments.

Recommendations to others considering the product

Docker is still a relatively new technology, in large corporations, this product may not be yet certified for production use due to slow approval cycle.

What do you dislike?

Though this is not Docker's fault, I would like to be able to run a native macOS kernel instead of a linux one. Apple needs to embrace this as part of their ecosystem and support the community on this effort, much the way Microsoft has.

What do you like best?

Docker is a lightweight and and faster than using a VM in my development workflow. Because Docker runs on Mac/Linux/Windows it has proven to be the most important way to experiment with new technologies and is integral to my development CI/CD workflow.

Recommendations to others considering the product

Initially the Docker/Container concept may be difficult to wrap your head around, especially into regards to it's value. My recommendation is to install it, and try it out. Once you have deployed multiple services and are running them on your machine, it will be hard not to imagine the possibilities.

What do you dislike?

Docker has many feature that could be helpful to our team. I wish there was an area where we could access tutorial of what we can do with docket. We feel like we aren't using it to its max capacity.

What do you like best?

Docker provides a very novice environment to build, manage, and test our applications that we work on. It is also a great collaboration medium to keep track of our projects. We also like the deployment feature that allows us to get new versions of our application fast and easy

This is a great platform if you have a huge company. You will really get everything out of the money you spend.

What do you dislike?

- Lots of configurations to get some containers running.

- Containers don't have generic guidelines to start. Different containers take different skills to get up and running.

- Sometimes, the containers may die. Though this is not Docker's fault, it is application fault.

- Around 5-7 containers, my machine starts to give up.

- I don't like Kitematic. It can be more refined. Currently it doesn't even show logs properly, and is slow and brittle.

- Docker itself is small, but not all applications built inside docker are small. E.g. Just adding a language and couple of libraries would increase your storage significantly. This is not a docker fault per say, but not all applications have been re-worked to lower the memory and storage footprint.

What do you like best?

- I don't have to install any software. Everything is dockerized!

- I can run multiple copies of everything for scaling.

- Containers start instantly. So fast.

- After I delete containers, no residue is left. It is truly a sandbox.

- Docker perfectly manages its storage space. If you are downloading two similar images, docker would only save the common parts of those images once.

- Docker is ever-growing. This is the future, and development is very active. You get new updates very often, and you can tell that they are moving in the right direction.

- The concept of containerization as a whole is so supreme and powerful, that you are really missing out, if you have not dockerized your applications yet. Docker has really redesigned the whole pipeline and deployment game.

Recommendations to others considering the product

Just use it. Everyone else uses it, and for good reason.

What do you dislike?

I did dislike the lack of first-class support for Kubernetes, but they have recently released support for this orchestration technology. So, I am very happy with the changes in this area.

What do you like best?

I love that Docker not only does containerization well, it makes it easy. With all of the tooling they have released it is a breeze to dive in. The community is amazing, for support as well as coming up with external tooling based on the Docker containerization technology.

Recommendations to others considering the product

I definitely recommend installing all of the command line tools and really understanding the core concepts of containers, images, and how Docker's virtualization takes place. From this point you will have a great vantage to be able to implement as to your needs. Once you have solid footing here, check out Compose.

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 one more thing is its command line is boring, long and one big downside is that Docker need to download the essential files of the selected operating system in container, so if you want to keep synced your Docker image between two computers, it is a big pain.

What do you like best?

Docker made containers easier and safer to deploy with a much more standardized container system. Allows my team to deploy to the cloud easily and scale on the fly. Containers are where companies should be moving to and docker makes it easy, I highly recommend it.

With Docker, developers can build any app in any language using any toolchain. 窶廛ockerized窶� apps are completely portable and can run anywhere - colleagues窶� OS X and Windows laptops, QA servers running Ubuntu in the cloud, and production data center VMs running Red Hat.

Docker helps developers build and ship higher-quality applications, faster. also developers can automate their build pipeline and share artifacts with collaborators through public or private repositories.

Docker helps sysadmins deploy and run any app on any infrastructure, quickly and reliably.
