Docker Reviews

We're utilizing Docker extensively as all our products and services are deployed on Kubernetes, which is based on Docker. Our reliance on it is high. We have various services, including Python, C++, and Node.js, and several applications that are deployed via Docker. Our usage of Docker is almost 100 percent across all entries.

The most valuable feature of Docker is that it revolutionized virtualization by providing a new approach with containers that completely nullified the time it used to take to deploy applications on virtual servers, resulting in deployment times that can be as quick as milliseconds, unless it is a heavy application, such as Java. Additionally, resource utilization has greatly improved with Docker, allowing for more resources to be allocated to other tasks. These are a few key features that make Docker a preferred choice.

There may not be much room for improvement with Docker as it has greatly evolved. However, one area that could be improved upon is the documentation on their website which was once easy to follow but has become quite terrible with numerous versions being released. As an example, the installation process for Docker now requires more than just a one-line command, causing inconvenience. Additionally, based on my experience as a college instructor, teaching students to install Docker was a difficult task due to the lack of straightforward and easy-to-follow documentation. Docker should focus on improving their documentation to make it more user-friendly for all.

In an upcoming release of the solution, the UI should be made even more user-friendly and comprehensive, as it currently requires a multi-step process to set up a registry or host a container. A one-click solution that streamlines the entire process and makes storing, leaving, and cleaning up images significantly easier. This feature would greatly benefit those who have previously struggled with additional cleaning when hosting their own container, and it would make the end-to-end Docker experience more accessible and efficient.

I have been using Docker for approximately 10 years.

Docker has various integrations, such as Docker, Compose, Docker Swarm, and Kubernetes, I have witnessed a considerable amount of downtime resulting in applications going down. Unfortunately, it has been difficult to pinpoint the root cause of these issues. Thus, I would say that Docker is not completely stable, with an estimated stability rate of around 90 percent. As a precautionary measure, I deploy my services on multiple stations with proper scalability and high availability to mitigate any potential downtime.

We only have engineering users using Docker which is approximately 50 percent of our staff. We have a total of approximately 25 people using the solution.

The solution is scalable.

The initial setup of Docker was easy but this has changed. The setup is not necessarily difficult, but it has become quite confusing. As long as I am familiar with all of the necessary commands and don't encounter any unexpected issues, it should be a relatively straightforward process. However, the written instructions are so convoluted that it may prove challenging to install everything without encountering any obstacles.

Docker has made some changes and there is an enterprise version that is affordable.

This solution is doing its job well. The stability could improve, but the other parts of the solution are great.

I rate Docker an eight out of ten.

The solution is used to run systems in small applications.

You should start by running your applications to ensure optimal performance in a Docker environment. The administrator should validate the setup with Kubernetes before deployment. This process includes validating our software applications and comparing features with other open-source alternatives. It’s important to understand that application performance can vary due to various factors. For instance, issues may arise due to ZDR policies. Before deploying in production, consider using OpenShift if additional features are needed. Our organization currently uses Oracle, but Docker provides a flexible and efficient way to manage our applications.

We use Docker to facilitate deployment, updates, and management.

Enhancing artificial intelligence capabilities and cluster management should be a priority. It should facilitate some security management.

I have been using Docker for four years.

I have been going through the session block for enhancement. I rate the solution’s scalability a six out of ten.

The initial setup is straightforward.

It requires a premium subscription.

The CI/CD was created, and the template is there. It's sufficient to prevent blockers. The restore is deployed, and we are conducting large-scale scans to identify duplicates. For continuous intelligence, we are using Azure DevOps tools from GitLab. We use Docker for various tasks like scanning, automation, testing, and searching.

We support software implementation and maintenance. Nowadays, we update our software regularly. Our recommendation for regular users is to avoid using outdated software, especially when it involves personal data sources such as software applications, desktops, and internet usage.

Azure uses Docker and integrates with Azure products. Docker overlaps the network, which facilitates communication between containers. This network operates on VPNs but can utilize third-party gateways to reach and solve problems.

Docker has more advanced authentication, backup, and accountability.

Overall, I rate the solution a six out of ten.

We use the solution for containerization. We've replaced it with other solutions. We are using it to compartmentalize some legacy products. We are also onboarding other third-party applications using it. We have a few use cases. 

It's helped to save many resources.

The features, such as scaling and high availability, have been excellent. 

It is easy to set up. 

The solution is stable.

It can scale well. 

The pricing could be a bit better. We'd like the least amount of spend as possible.

We'd like knowledge transfer to be easier.

The support could be better. 

The solution can be a bit expensive. 

I've been using the solution for about six years so far. 

The solution has been pretty stable. 

The solution can scale well. 

I'm not sure how many users are currently using the solution. We are migrating all development teams over to containers. 

We have support from our vendor and also use support for the Kubernetes cluster. It could use some improvement. It could be a bit better. They should be more responsive. 

I've been working with Kubernetes alongside other solutions. 

The implementation, for me, was pretty simple. I'm not sure if others would have issues. 

I would deeply it on top of the Kubernetes cluster. It usually takes one day to deploy. We're using Docker as a service for testing purposes and have implemented it on Kubernetes clusters in order to test and deploy applications in order to handle production-grade applications. 

Have not looked into ROI to see if we have witnessed any. 

I'm not sure what the exact pricing is. I don't deal with licensing. However, my understanding is it is expensive. 

I started using the trial version and moved on to the latest version. 

I'd recommend the solution to others. I'd rate it nine out of ten. 

In our company, I have used Docker to launch an application publicly. The aforementioned application becomes available to end users via CloudFront. Docker is also used to cache the optimized performance.  

Docker hasn't been directly able to improve our organization's deployment processes. 

Docker offers a resilient system with minimal failure chances and optimized performance. For example, if an EC2 is utilized, the software container can be customized to allow only the specific benchmark of resources to be used. I found the solution to be easily customizable. 

The vendor should release a monitoring tool or include monitoring capabilities in Docker that can be used to monitor container performance and other Docker-based solutions. 

I have been using Docker for two years. 

I would rate the stability a nine out of ten. As containers are isolated and not dependent on each other, stability is satisfying in Docker. With the solution, when one service is down at the production end, it won't affect the functionality of other services running in parallel. The solution can be considered stable 99% of the time. 

I would rate the scalability an eight out of ten. Docker offers satisfying scalability features, and it depends upon the correct configuration being run within the virtual machines. Scalability in Docker is easier to manage than in legacy-based documents.

Presently, Docker is used by only me in our organization. Docker is an open-source solution. In our organization, we work with Docker on average once a week. At our company, we are not planning to increase the usage of Docker. 

Previously, applications were directly deployed in the server in our company instead of packaging the applications and running them on isolated environments. For instance, if any application experiences outage, it affects the other services as well, but with Docker this issue doesn't arise. 

I would rate the initial setup a ten out of ten. Docker offers an effortless setup process. As part of the setup, I have faced some configuration failure issues in Docker compose utility, but I was able to resolve it on my own with some changes in configuration. A feature of Docker can be made live in 20 to 30 seconds but the total deployment of the solution took me around one and a half days. 

As part of the deployment process, I inputted the code in the local environment and tested it on my personal computer using the Docker desktop utility. Following the aforementioned step, I pushed the code to the cloud and cloned it in EC2. Then, I developed a few necessary configuration files for Docker deployment and building.

As the last step of the deployment, the commands are run successfully to make the solution go live. Only one professional is enough to deploy Docker. To implement maintenance for a production-based cluster, a team of three professionals, one lead and two other team members, is needed. 

It's an open-source solution, so it doesn't cost anything. 

Docker is a trending tool and is being used for numerous production based applications, so instead of evaluating multiple tools, our company adopted Docker. 

I find Docker to be a user-friendly product. Docker acts as a stand-alone application without any dependency on other hardwares, so it can be used in an isolated environment. The tool can be easily customized. 

In our company, the product is running on EC2. I have restored all the required packages and need to compile the code within a container using the Docker tool. After the aforementioned step, Docker is used to run a few specific images where images are not dependent on each other. If one of the running images on Docker malfunctions, there won't be any cases of outage because the environment remains isolated. There is no interdependency between containers in Docker. 

Docker's container orchestration capabilities support our organization's projects with minimal downtime and low failure chances and offer a robust system. Our company has a Docker compose utility to customize the workflow and make it operate smoothly. Overall, I would rate the solution a nine out of ten. 

When we are developing an application, we try various libraries. It is better to isolate one application from the other because if they install one library and then it doesn't work on the other end or while using a driver, then it doesn't work on the other driver. There is always this conflict that is bothering us, and that is where Docker separates containers to build applications.

Docker is a useful tool that we just implement and use directly.

It is a perfect solution for me stability-wise. Owing to a few shortcomings in its stability, I would say that its stability can be improved. It is important to note that I am not an expert to speak about what needs improvement.

In the future releases of Docker, we should be able to isolate a couple of applications. It should also be possible to isolate an environment.

I have been using Docker for one or two years.

The solution is stable.

The solution is scalable.

We have a couple of users in our organization using Docker since it's just a test system right now.

We don't have plans to increase usage.

We haven't contacted the technical support of Docker. We did search for the details of Docker's support team on Google.

We have used the virtual machine named VMware previously. We switched to Docker because VMware was very clumsy when we tried to build a lot of virtual machines using it. VMware is best suitable as a business solution.

The initial setup of the complete environment is complex, but Docker is easy to set up.

If you want to set up a complete environment, it will take a week, depending on the applications.

We don't do the deployment since we only look into the PoC phase. The company we work with does the deployment, and then they worry about the environment, infrastructure, and other things.

We do the deployment by ourselves because we need to test or develop some applications and do the PoC phase.

Docker is perfect for what I do, though it is really limited as a tool.

Overall. I rate the solution a ten out of ten.

Our primary use is to deploy the applications in a secure environment. We prefer that our developer and the Docker files can make the images. After we have captured the images we use our CI/CD tool and deploy our applications. This makes our publisher fast and our containers are isolated from each other. We increase our security by using Docker. 

The most valuable feature is Docker has a fast learning curve. There are a lot of default options that when you use Docker you do not need to customize or configure it in a way that it slows you down.  The user interface is very nice as well. Docker has good security.

One item that could be improved is the overall stability of Docker.

I have been using Docker for one year.

For the most part, Windows is stable, but sometimes the application crashes and we have to have an error fixed in order for the stability to remain. When it comes to Linux it is not so compatible.

The reason why the company decided to use Docker is that it is easy to learn.

The setup is easy and straightforward.  The Docker site is comprehensive, and you can find all of the documentation, API, details, and comments you need to deploy.

The current cost for us is nothing as an open source.

I would recommend they use the online videos and tutorials and after a week they are going to be ready to start. I would recommend it to anyone to use. I would rate Docker an eight out of ten.

I use Docker to create dev stacks, usually for developers to plug and play their applications, and in cases where they don't need to be bothered with complex architectures and decoupling services. We create a simple Docker compose file and provision it. We are customers of Docker and I'm a DevOps engineer.

The lift and shift is valuable because you create a lightweight image that can be accessed by anyone who has installed Docker.

I'd like to see improvement in some of the documentation because there are currently errors and it requires a thorough check and deep dive to make sure it's correct. If they were to incorporate what the community offers into the documentation, it would be beneficial.

Many people use multiple containers for their workload and it would be great to have pre-deployed solutions for typical deployments like WordPress and multiple CMS which would encourage more developers to use Docker. I would love to see the solution with pre-baked, ready-to-go capabilities for multi-container solutions.

I've been using this solution for five years. 

I haven't found such complex issues that I need to contact customer support. I found most of the answers through the community or using a work around. 

The initial setup is very easy. You just need some basic understanding of the system, and how containerization works. Images are already prepared so if the user doesn't have the images on his local system, Docker pulls it from the repository and it's good to go. It's much faster if the images are downloaded. As a DevOps engineer, I generally carry out the deployment myself. 

I recommend learning about containerization prior to using this solution starting with basic deployments. Take the opportunity to test it out and check the components. Docker has relieved a lot of the pressure, including the fact that I no longer have to provide everything from scratch. I know I just have to install the Docker community edition, make Docker images and get going. That said, Docker has some limitations and Kubernetes has discontinued using it. It's compatibility is reduced as a result and many organizations are moving towards Kubernetes and other orchestration services.

I rate this solution seven out of 10. 

Docker helps us implement applications quickly.

Docker is convenient and easy to use. We can create and implement different types of virtual machines. It provides a lot of flexibility. The applications can be deployed quickly.

The stability could be improved.

The product is stable and reliable. I rate the stability a nine out of ten.

Five engineers in the IT team use the product in our organization.

The support team is fast, customer-friendly, knowledgeable, and quite professional.

We didn't face any issues with the installation.

We deployed the tool in-house.

The tool provides a return on investment. We are able to deploy some services and applications faster and be aligned with business requirements.

We have a monthly subscription. The product is not expensive. I rate the pricing an eight out of ten.

We do not use the solution often. It works well. We don’t have huge projects. I will recommend the tool to others. Everyone in IT uses Docker. Everyone knows it. At some level, a company must find a way to use Infrastructure as a Service by implementing different container technologies like Docker. Many IT personnel are aware of the solution. Overall, I rate the tool a nine out of ten.
