Local container testing has boosted development speed but still needs lower battery and memory use
The main thing that really frustrates me about Docker is how much battery power it consumes on a Macintosh. I really am not a fan of that, which leads me to not want to run Docker 24/7 because I do not want my laptop battery to be exhausted by Docker instances running or even the Docker CLI or UI being booted up. I tend to not have it running until I need it, and then I run it and close it. It would be really nice if it did not consume as much battery as it does currently. Docker can definitely be improved by reducing the battery and CPU load that it impacts on a Macintosh. If it were possible for me to run Docker without panicking about the battery running out, that would be excellent. I believe battery is the biggest issue with Docker. The other issue is memory. It seems to consume a lot of memory, and I am not a fan of that. This means that I need to have a really powerful, high-specification Macintosh with a lot of battery and a lot of memory for it to work reliably. I do not always have access to that. If Docker could consume less battery and less memory, that would be magnificent.

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 solution's most valuable feature is the Dockerfile, which makes the life of developers easy. Developers get a real understanding of container creation."
"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."
"The tool's most valuable feature is its sandbox environment. It makes it very easy to run and test applications without needing configurations, which is the core advantage of containerization. Kubernetes and Helm are helpful as they provide high-level metrics, making tracking the status of all the containers and applications running easier."
"We find the auto scaling and auto healing functionality of this solution very good."
"The initial setup was easy, and you are only required to run commands."
"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."
"The solution offers speed and flexibility."
"It is neat and very flexible."
"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."
"They should provide proper documentation to understand the solution's cgroup process."
"As for improving Docker, I would like to see enhancements in its user interface and documentation to make it even more user-friendly and accessible. I believe Docker will expand its scope and reduce limitations to support more applications, both online and offline. For instance, in scenarios like deployments on ships or during upgrades, Docker can continue to offer software services and container-based intelligence."
"The learning curve with Docker is huge and extensive"
"Deployment could be quicker."
"The solution needs to be more scalable for local machines."
"The security layer is very vulnerable, although they are working to improve the system hardening and email hardening."
"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."
"Portainer needs to be more intuitive."
 

Pricing and Cost Advice

"I use the solution's open-source version."
"Docker is a free tool."
"We use the open-source version."
"The pricing of the solution is fairly cheap."
"It's free."
"We are using the open-source version of the solution."
"The offering and service are quite free."
"It's an open-source solution, so it doesn't cost anything"
