Time-saving deployment with seamless virtualization for diverse environments
I used Docker to Dockerize Java code. We had a code base, and I needed to create a Docker image from it so that it could be deployed. At the time, we used Docker Compose, which is somewhat similar to Kubernetes Docker allows virtualization at a higher level without the need for a host machine.…

A GUI solution that helps to administer a docker using a browser
The first time using Portainer involves a learning curve. It takes longer as you're unfamiliar with the processes and might be lazy to consult the manual. Initially, you may rely on intuition within the GUI. However, after repeating the same tasks three or four times, the process becomes much quicker.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature of Docker is its integration with other solutions, such as KVM and AlmaLinux."
"It is a very stable solution. Stability-wise, I rate the solution a ten out of ten."
"The tool helps us in code versioning. I think it's pretty much easy to use and very straightforward. Even if someone is new to the tool, they can easily start using it with a little guidance or theoretical knowledge. Go through the tool and start using it without much struggle."
"Traditional deployments take more time and builds can be inconsistent across different environments. Docker solves these issues."
"When used in conjunction with Kubernetes, it is seamless because it integrates very well."
"We are using Docker to host applications."
"I think that with Docker, it is easy to deploy it on different platforms."
"The most valuable features of Docker are its security, detailed documentation, and ease of use, and the Docker Swarm is not as complex as Kubernetes."
"Portainer comes with the ability to take the information of docker definition. Using it, I can visually observe how the container has been created. It allows me to create networks. I can also visually generate volumes and working stacks."
 

Cons

"The solution’s documentation could improve a bit."
"We would like to see improvement in adding the node into the Docker Swarm cluster, as at present it is a little tricky and requires a lot of manual steps."
"If you install Docker on a host, it creates its own firewalls. It can become an issue. Usually, when you want to install Docker, you need to restart the firewall or restart the active tables on the machine, but this is not the case with Kubernetes. It uses the default set up by the next administrator, but with Docker, you have to restart the firewall and restart Docker before the firewall on the system will be okay. If you do not the rules will not be created."
"The runtime and security could improve in Docker. Security is paramount in the cloud and important."
"There is always room for improvement. I often refer to forums such as StackOverflow to learn from other developers' experiences and the challenges they have faced while using Docker."
"They should provide proper documentation to understand the solution's cgroup process."
"I think Docker can improve as it relates to overall stability."
"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."
"Portainer needs to be more intuitive."
 

Pricing and Cost Advice

"The solution offers an open-source version that is free and includes a lot of functionality."
"Docker is cost-effective and open-source."
"Customers pay for the license through a yearly subscription model, where they pay per license. This means that the license is based on a subscription, and the customer pays annually for each license they use."
"Pricing is based on the number of users."
"There is a license needed to use Docker."
"It's free."
"Docker is a free open-source solution."
"The pricing of the solution is fairly cheap."
