Docker Reviews

Docker works on every platform and makes it simple to match production and development systems. It's similar to older virtual machine and VM management tooling, but much more lean and 100% open source.

Getting started can be intimidating. While it's worth the time invested, development teams accustomed to working directly on their own hardware or with traditional virtual machine tools will have a bit of a learning curve.

I think the most impactful and beneficial thing about Docker is the capacity to hold an entire program with an insanely low size (30MB for an entire and fully operational Alpine-linux!!). This enables a world of microservices to be created and never depend on one thing, you can have 6 different micro services hosted on 6 different containers and each and every one can be resetted without holding the rest hostage.

I think the implementation process could be easier, sometimes you really need an easy-access terminal and Docker is not that friendly when it comes to that, I have high hopes that they can resolve that issue, for example as Anaconda did, a separate executable terminal for each virtual environment, this could be a separate command terminal for each container.

First of all, it's very easy to use. If you have experience on powershell or other batch scripts, you can handle docker command perfectly. Docker changed the world deeply. Container architecture is certain to happen all devops processes. With Docker, software development process and shipping are quite simple. It's because Docker provide a standard file system and command scripts.

If you are Microsoft Windows 10 user, you need to install specific version of windows that supports Docker. When you decide to use Docker, you have to buy a security application to secure docker file and docker images, containers. So, it is another cost.

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 is great for setting up development environments for projects and making sure everyone is working on the same basis. That includes locally as well as in production environments. Once you have you have your configurations set it becomes trivial to drop it into any project with similar requirements. It's very flexible in what it allows you to do. It definitely speeds up the on-boarding of new team members.

Docker works 99% of the time. It's fairly reliable. Every now and then things won't work for no reason. It usually ends up being some or other obscure issue. Luckily enough if you search hard enough there's usually someone that has experienced the same problem and has managed to resolve it. There's thankfully many ways to tackle a problem when it comes to 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.

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 the DevOps Tool that is used to for Containerization. It's the best tool to automate the build, Deploy and Release Management. By using it,the risk of human error is eliminated. It can be integrated with any operational infrastructure or multiple cloud. It boosts the agile process with DevOps methodology. The enterprise level of security delivers the application with a protected way. Best thing in it is Docker simplify the development process with the automation with the help of containerization.

In every release of docker, we need to check and test the compatibility of our product before implementing it, which is totally unplanned. It should come with more brief documentation as the learning curves are sharp. The integration of some cloud based services is not stable.

Docker made the deployment across a heterogeneous ecosystem very easy and much faster than before. Helped integrate across diverse platforms with less effort on my part.

Mini-docker containers were a little difficult to manage and the app didn't include free software to manage them. What good is a technology that lets you package and ship out the apps without giving you a way to mange them as well?
