Easy to set up, helps save on resources, and offers high availability
Pros and Cons
- "The solution is stable."
- "We'd like knowledge transfer to be easier."
What is our primary use case?
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.
What is most valuable?
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.
What needs improvement?
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.
For how long have I used the solution?
I've been using the solution for about six years so far.
What do I think about the stability of the solution?
The solution has been pretty stable.
What do I think about the scalability of the solution?
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.
How are customer service and support?
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.
Which solution did I use previously and why did I switch?
I've been working with Kubernetes alongside other solutions.
How was the initial setup?
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.
What was our ROI?
Have not looked into ROI to see if we have witnessed any.
What's my experience with pricing, setup cost, and licensing?
I'm not sure what the exact pricing is. I don't deal with licensing. However, my understanding is it is expensive.
What other advice do I have?

Azure DevOps Lead at DXC Technology
Allows us to containerize microservices but could be more UI-based
Pros and Cons
- "Containerization is the most valuable feature. I can communicate to the Docker containers using other containers."
- "I would like to see a more UI-based tool so that students can easily understand it rather than memorizing all of the Docker commands."
What is our primary use case?
We used to have a silo problem. Docker solved it because we're able to containerize the microservices that we're developing in the form of Docker mail.
Once we run the Docker image, it becomes a container. This container is guaranteed to run in every machine because we're installing Docker as the platform. On top of Docker platform, we're curating the Docker images and running the container. That container has a limited number of libraries and a limited number of data, which is required to run the application.
Each container has a limited library system, which is required to run the application. This encapsulation makes it work perfectly, irrespective of the system. It works perfectly once we have encapsulated the application and containerized it. This is guaranteed to run in each machine.
We're deploying the solution on Azure cloud. We're curating the CI/CD pipeline. In the CI/CD pipeline, we're curating the Docker images and pushing it to the container registry. We're writing the steps for how to build the Docker image into the YAML code. Once the Docker image is built, it's pushed to the container registry. We're writing this YAML code in the pipeline.
Every person on the DevOps team is using this Docker tool.
We have plans to increase usage because it's a great tool, and it's the latest technology. We're no longer developing monolith architecture, so everyone is developing applications with microservices. Docker is the best tool to containerize the application and encapsulate it.
How has it helped my organization?
We used to work on monolithic architecture to develop the application until it goes to the production environment. It takes a huge amount of time. Now, we are using a microservices architecture. Rather than creating the application as a whole, we are dividing the application into small services. Each microservice is loosely coupled. With each microservice, we can develop and containerize it in the form of a Docker container.
If an application has a hundred microservices, like on an e-commerce portal website, then the login is usually one application, the catalog is one application, and the E-card is one application. Each application can be considered as one service. For each microservice, we can develop a code and containerize it.
What is most valuable?
Containerization is the most valuable feature. I can communicate to the Docker containers using other containers. The copying feature is helpful because if a container dies, we won't lose the data. That data is retained because of this data volume feature. We mount it to our shared system or any shared folder.
What needs improvement?
I would like to see a more UI-based tool so that students can easily understand it rather than memorizing all of the Docker commands. Some people try using Docker desktop and containers to make it graphical.
Docker Swarm could have more advanced features, like Kubernetes, which has an auto scaling feature and cell-filling capabilities.
For how long have I used the solution?
I have used Docker for four years.
What do I think about the stability of the solution?
I would rate the stability as seven out of ten.
What do I think about the scalability of the solution?
I would rate the scalability as seven out of ten.
How are customer service and support?
I would rate technical support as seven out of ten.
How was the initial setup?
Setup is simple. We can install Docker with just one command. It doesn't take more than three to four minutes to run the pipeline. A Docker image is built in that time frame.
We're running the pipeline in a self-hosted agent or Microsoft-hosted agent.
Docker Compose can be installed easily. It allows you to use multiple containers at a time. Docker Swarm can also be installed easily.
What's my experience with pricing, setup cost, and licensing?
Docker is open source. To use a Docker enterprise model, we would need to pay for it.
What other advice do I have?
I would rate this solution as seven out of ten.
My advice is to create an account on Docker Hub. In Docker Hub, there are three Docker images available for practice. We use GitHub to see how we're making the Docker images and then push it to the public Docker Hub. I have an account in Docker Hub and have images there that I can reuse later. I would also advise completing a Udemy course for Docker or watching YouTube videos about it. This will make Docker easier to understand.
Which deployment model are you using for this solution?

Lead Machine Learning Engineer at Schlumberger
Simple implementation, easy to use, and large user base
Pros and Cons
- "The most valuable feature of Docker is that it provides a containerized environment. The isolation between the environments is beneficial. Additionally, the solution is easy to use."
- "Docker can improve the integration with Microsoft Windows. It does not support native installations."
What is our primary use case?
Docker can be deployed on-premise or on the cloud.
We are using Docker for containerizing our applications.
What is most valuable?
The most valuable feature of Docker is that it provides a containerized environment. The isolation between the environments is beneficial. Additionally, the solution is easy to use.
What needs improvement?
Docker can improve the integration with Microsoft Windows. It does not support native installations.
There can be a lot of issues with Microsoft Windows and Docker and those issues should be resolved in a future release. For example, if you are running Docker and you are running a lot of things in Microsoft Windows, these issues should be resolved.
For how long have I used the solution?
I have been using Docker for approximately
What do I think about the stability of the solution?
Docker is highly stable.
What do I think about the scalability of the solution?
The scalability of Docker is very good.
Every machine learning group in my company uses Docker. We have approximately 2000 to 3000 people using it.
How are customer service and support?
I have not needed to use the support from Docker because I have not had any issues.
How was the initial setup?
The initial setup of Docker was extremely easy. The only part that takes some time is the containerization, the rest of the process is quick.
I rate the initial setup of Docker a ten out of ten.
What's my experience with pricing, setup cost, and licensing?
Docker is a free-to-use solution. However, Docker Enterprise is not free.
Which other solutions did I evaluate?
We chose Docker over other solutions because it has a relatively large use user base. It is a popular solution.
What other advice do I have?
If you are trying to use Docker for the first time, make sure that the Docker file you have or the containerization which is done, is done properly. If the containerization is not done properly there can be some folders that are not mounted correctly and it causes several issues.
Docker Enterprise takes less time to set up if I was to compare it to this Docker free open-sourced version.
I rate Docker a nine out of ten.

- "The most valuable feature is that it gives you the same environment as on a developer machine as well as a production machine relevant to specifications, with binaries and dependencies all bundled together in a similar fashion in both places."
- "I would like to see better management layers."
- "I would like to see better management layers."
What is our primary use case?
Our primary use case is to build and bundle applications.
What is most valuable?
The most valuable feature is that it gives you the same environment as on a developer machine as well as a production machine relevant to specifications. The binaries and dependencies are all bundled together and they are in a similar fashion in both places.
What needs improvement?
I would like to see better management layers. One example of this would be binary shipping. I would also like to see Docker utilize a concept like Red Hat Family.
For how long have I used the solution?
I have been using Docker for three to four years.
What do I think about the stability of the solution?
The stability is excellent. Sometimes, memory management can be tricky.
What do I think about the scalability of the solution?
Docker is scalable on both community and commercial levels. I am using the community version. There are around one hundred to one hundred and twenty of us using Docker on a daily basis.
How are customer service and support?
For customer support, we are using the documentation on the forums and they are suitable.
How was the initial setup?
The initial setup was very simple and straightforward.
What about the implementation team?
You can use either an in-house or vendor team. We simply downloaded Docker into our organizational environment.
What other advice do I have?
There are a sufficient number of YouTube videos and best practices to build Docker. I would encourage a potential user to investigate those videos. On a scale of one to ten, I would rate Docker a nine.

Open source containerization platform that removes environment dependancies and can be deployed anywhere at any time
Pros and Cons
- "There are ways of using Docker where you have absolutely no dependencies on the environment that you work in. This allows us to deploy Docker anywhere anytime and this has been most valuable."
- "There are ways of using Docker where you have absolutely no dependencies on the environment that you work in, which allows us to deploy Docker anywhere anytime and has been most valuable because it removes any dependencies when it comes to deployment."
- "There are elements of stability that are problematic. One of the most recent upgrades created a major incident on our cloud, whereby the containers were not restarting automatically."
- "There are elements of stability that are problematic."
What is our primary use case?
We use this solution for our web applications and websites for automatic deployment. We also have a cloud based solution that we sell as a product and we offer cloud hosting, which is Docker based. Our clients have access to a graphic user interface where they can deploy their websites with one click and we use Docker in the back end to make that possible.
Docker is an entirely containerized cloud solution that supports different types of applications running on the cloud including websites, web applications, APIs and some Lambda functions. We have a whole bunch of stuff running on the cloud. We have thousands of users supported by this solution.
What is most valuable?
There are ways of using Docker where you have absolutely no dependencies on the environment that you work in. This allows us to deploy Docker anywhere anytime and this has been most valuable.
Docker removes any dependancies when it comes to deployment. We can ship it between different devices and different locations without our clients being impacted or aware. In once instance, we redeployed a client's container without losing any of their data.
What needs improvement?
There are elements of stability that are problematic. One of the most recent upgrades created a major incident on our cloud, whereby the containers were not restarting automatically. Docker is a fairly new application and has matured and improved since 2016 but still needs improvement on stability.
Prior to using Docker, we used a CH root and jailing process. Essentially, Docker is a CH root on steroids combined with an image management system that is based out of git code. When you're dealing with such low level technology, there should not be issues with stability.
For how long have I used the solution?
We have been using this solution since 2016.
What do I think about the scalability of the solution?
This is a scalable solution
How was the initial setup?
The setup on the most recent versions of Windows is pretty straightforward. The setup on Mac is also pretty straightforward, but there are networking problems. Docker, it doesn't play well with the Mac virtual hypervisor. There are some issues on that side. On Linux, well, it's less straightforward, you have to know how to work it out. There are no performance or networking issues.
What about the implementation team?
We have done in house deployments and we have also used other tools like Kubernetes or Docker Compose. We have our own PHP library that can deploy Docker containers, which is called Linux for Composer. It is oriented towards helping PHP developers to use Docker to make things more simple.
What was our ROI?
We have definitely experienced ROI because it cuts down on development time. There are no surprises when it comes to deployment. It cuts down on development, deployment and it cuts down on staff. There are multiple advantages including on the financial side.
Which other solutions did I evaluate?
We've had a look at other possible solutions such as KVM and Pod Man. Pod Man is not very mature right now. There are a lot of things that we're used to being able to do with Docker that we can't do right now with Pod Man.
We're not excluding the possibility of using Pod Man. There is also an equivalent to Docker which is the Windows subsystem for Linux, WSL two. We've used that for a few projects in Windows environments, and we are considering putting our Linux distribution on WSL two.
What other advice do I have?
I would advise others not to use Docker as a virtual machine or to think of it as being similar to VMware or Virtual Box. It has an entirely different use case. They have to think about it as a system that is used on an ad hoc basis.
If you build thinking that it is temporary in nature, you will have the full benefits of Docker.
I would rate this solution a nine out of ten.
Which deployment model are you using for this solution?
Hybrid Cloud
