Docker Erfahrungen

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.

Docker is a powerful tool for containerization. It gives the platform for build, test and deploy application using container. The Docker container helps in adopting the DevOps methodology that helps in rapid release. Docker container helps to isolate the application which helps to execute the consistent test results. Dockers helps to optimize the development and operational process. Docker Enterprise provides a one stop solution to all problems from its dashboard.

Docker daemon configuration for container and images is a tricky part and it should be simplified. Managing the Swarm and Kubernetes for orchestration is a complex part with using Docker API.

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.

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.

Containers are quick to deploy and you can have dedicated machine that run software you don't want (or you cannot) install on any machine in your network.
I have a Zabbix docker machine, an uniquity one and also a snort one.
I usually install docker on linux machines (I choose Ubuntu in my case) but you can also use docker on QNAP Nas systems, really useful and easier to setup.
Installation of docker is easy, just follow the instruction on main site. Installing applications is also easy.
Highly recommended!

You need a Linux machine and a little knowledgement to run successfully docker, but there is a lot of documentation on internet

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.

The advantage of Docker is that it provides an easy way to deploy applications on multiple platforms and can run on multiple operating systems. It also offers a consistent development, testing and deployment environment. Additionally, it is lightweight and can be easily deployed on minimal hardware which can help reduce costs. The software is also secure, as all containers are isolated from the rest of the system, eliminating the potential risk of malware.

Among its weaknesses or shortcomings is that it can be complicated to set up and manage its environment. It's also lack customization options can be a limitation depending on the complexity of the application. Also, docker containers can be expensive, especially when using proprietary and closed source images.

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 is the ideal container virtualization for private as well as commercial software projects in need of scalability. Docker impresses with its do-it-your-way building block principle, which implements simple and platform-independent develop- and deployment solutions.

Ingeniously, Docker enables cross-project development of software as if it were already in a deployment mode.

Actually, there are hardly any drawbacks with Docker. When it comes to small-scale troubleshooting, the fixes are mostly robust and long-lasting. However, images can sometimes become too large because developers want to avoid the time-consuming work of memory optimization.

1. Containerization - this wasnt even a word before Docker made it a household verb for every developer. Allowing multiple services to be independent of each other, in other words to form a microservice by virtualization at the VM level. Its a Linux ship!
2. Rapid Deployment - developer can simply push the build and deploy happens atuomatically
3. Images are easily available in plenty for consumption
4. Intuitive command line interface
5. Its predicatable - Works exactly the same way on any OS platform and that augurs well for enterprise needs

1. Breaking a monolithic application into microservices is tough and hence, dockerization of an existing application can take some amount of investment
2. A bit of learning curve if not hands-on with linux.
3. High load throughput can be troublesome at times, docker hangs in such situations
4. Debugging can be a challenge sometimes
5. Backward compatibility with various Docker versions is also spotty.
6. Docker can be an overkill if the application is already on Amazon lambda, Elastic Beanstalk

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?

When I found Docker and what it can do I was amazed by how powerful it is. Each container is a closed environement like a VM would be but it is super easy to deploy and configure. I wish I would have known docker sooner as I had so much trouble migrating things from a server to another back in the days but now with docker it is so easy to do and this is just amazing.

I would like docker to have a web UI where you can manage your container from there. Yes you can use Portainer but I wish it would be there by default when you install portainer. A command line tool can repel some users to learn Docker.

Docker is used by millions, meaning that most software you'll encounter supports it out of the box. In addition to that you have their container registry, Docker Compose, and other helpful tools that make using it as frictionless as possible.

Docker is UNIX software created by people who probably never used a UNIX system. The usage is confusing and non-idiomatic. Moreover the interface is not well thought out - for example the poorly named and frequently confused "exec" and "run" commands.
