Mirantis Container Cloud Reviews

My experience with Docker is in helping to provide solutions for my clients. Specifically, this involves continuous integration and continuous deployment for my clients' workflow.

We are using Docker for a client that we currently have in India. They are building a solution for the medical industry. Docker is very helpful for taking the code from development and applying it to the end user.

The most important thing that my clients focus on is rapid deployment. In this regard, Docker wins hands-down.

It would be very nice to have a GUI that can be used by any administrator, and not just people who have experience with Docker.

The stability of this solution is perfect. Five stars.

This solution scales very well, and it can be scaled to the entire infrastructure when required.

Three of my clients are currently using Docker, and all of them are involved in software development. One of my clients is in the process of scaling up, moving from ten to one hundred and fifty developers within the next six months.

The documentation for this solution is excellent. So far, all of the problems that I have faced have been solved by looking at the documentation.

We did not use another solution prior to this one.

The setup was very straightforward. I just followed the documentation on the Docker website, and it went smoothly.

Implementation for the client was not very big. It was eight to ten developers, and it took between one and two days to complete. The most important thing on our end was to get our client's infrastructure up and running with Docker.

One person can handle the deployment and maintenance of this solution.

We implement this solution for our clients using our in-house team.

I am using the community edition, rather than the enterprise edition because I am operating on a very small scale at the moment. The community edition does not require a license and is completely free.

We did not evaluate options other than Docker.

My advice to anybody who is implementing this solution is to read the documentation very carefully. That can give a lot of relief when the client needs a solution.

If Docker had a graphical user interface then it would be a perfect solution.

I would rate this solution and eight out of ten.

I am using this as a lab costing application. It is pretty fast.

You can easily deploy it in different platforms and cloud providers. You are actually deploying container to container. 

The commissioning is very fast. 

I think this solution needs better security due to rising threats from the outside world. 

The product is stable. 

I am not scaling it very much at this time. I only have about 20 users at present. The roles of the users are information users, managers and middle managers.

The tech support is pretty good. 

It was straightforward for us. 

The pricing and licensing really depends on what your needs are. You could be paying $100 a month to $100,000. It depends on the needs you have from the solution, and the agreement you make.

This solution has cut down on our development time and allows us to spin off new instances for inner development, testing, productions, and security testing.

Areas for improvement are the privacy of container management and the documentation. In the next release, I would like to see best practices on how to manage distributed containers and networks.

I've been using this solution for about five years.

This solution is pretty much stable.

This solution is extremely scalable - we are able to spin off multiple instances very rapidly.

Initial setup was extremely simple and was done in minutes.

I implemented through an in-house team.

I would rate this solution as eight out of ten.

The most valuable feature of Docker is by far is creating your own image. By creating your own image, you can have an environment for whatever you are working on that is exactly how you want it.

The idea that you can create a machine this quickly, use it, destroy it if you want, build upon it, take things out, and rebuild very quickly is very useful.

For example, you could add a command that installs a certain tool to your Dockerfile and build that image. Your image now has that tool. If you want to get rid of that tool, you just get rid of the line from the Dockerfile, rebuild the image, and it’s like you never installed that tool.

It gives you a feeling of complete control. By comparison, doing the same thing with something like Vagrant would take a lot of time. With Docker, building an image is so fast that it’s practically disposable.

Docker has allowed me to have pre-defined working environments that can be moved to the cloud and I know they will be exactly the same. Something can be deployed to the cloud, but the overhead of running a virtual machine is wasteful. This is especially the case since on most clouds, an account is already contained by a virtual machine. Running a virtual machine within a virtual machine is possible, but not ideal.

Docker is already aware of how faulty their file system volume mounting technology is on the Mac. I see that they are making improvements in that area, but there is still a long way to go.

On the Mac, Docker is far from perfect. The program has issues communicating with the file system and receiving events. As a result, Docker’s volume features are very slow on the Mac. However, there is a workaround called Docker-sync. Docker sync goes around Docker’s weak volume support on the Mac by syncing files through the network using unison and rsync. Still, I would only give Docker a 10 if their volume experience were as good on the Mac as it is on Linux. I have used this product in a Mac environment as well as Linux.

I have been using Docker since November, 2016. I started using it to see what all the talk was about. The initial learning curve was somewhat steep. What Docker does is simple. However, understanding what Docker does is important and not obvious. That’s why I took Lynda’s course on Docker. This course gave me a good practical understanding of Docker. After understanding the basics, the documentation actually became useful to read.

In my experience, Docker has been very stable.

There have been no scalability issues. As a matter of fact, Docker itself can be used to help you scale up by allowing you to create a new environment quickly when you need more power, or if you want to deliver an instance closer to a customer.

In term of technical support, the Docker community is very helpful and active. There are already a lot of answers to common questions on stack overflow.

I previously used Vagrant. I switched because of Docker’s speed, ease of creating images, and its low overhead.

The initial setup of Docker on the Mac is simple. There is a very friendly GUI installer. If you already have Homebrew installed, you can simply run “brew cask install docker”.

Installing Docker on Linux is a different story, since the versions supported by the default package manager sources are out of date. It’s necessary to follow somewhat lengthy instructions from Docker’s website.

The Docker community edition is free. I don’t have any experience with their paid versions. I have not felt the need to upgrade.

I tried Docker because there was a bit of hype around it. I had been using Vagrant. I did not know about things like LXD before starting to experiment with Docker. If anything, I have learned about alternative container technologies that I might evaluate later.

I think that Docker is the best among its peers. Creating, downloading, uploading, and sharing images is faster than doing the same on something like Vagrant.

When using Docker on the Mac, I only used it to create a local development environment. I also have a Docker installation running in production on a production environment being used as the backend for an iOS app.

I would advise people to take the Lynda course on Docker. In my experience, the documentation only becomes useful after understanding the basics and the general idea.

Our primary use case for this solution is for electronic commerce.

It took us 30% faster to implement the solutions that we used to have with other platforms, and the flexibility has increased by 50%.

The most valuable aspect is the excellent support. In addition, the billing system is really easy to understand.

Sometimes the basic support is a bit difficult if you have a firewall and cloud servers behind the firewall and then try to implement the backup solution, it can be a bit difficult to do by yourself. If you have a Rackspace engineer, it is easier, because they know the procedures, but that service is not cheap. It can be an extra $500 for that extra service, per month. It would be nice to see that cost decrease.

The product is stable. Any problems that we have noticed have been with the customer doing something wrong. For instance, they may have two versions of the application that do not match, which will cause errors. But, we can never blame Rackspace Docker for this. It is an internal problem. 

The scalability is a bit difficult. Rackspace has beautiful tools to make scaling pretty easy. Usually, it is our customer that is afraid to scale too fast. At times, we have to convince our clients to move towards the cloud, because the cloud function is very different from the on premise solutions. Once they understand this, they are eager to jump to the next level. 

We currently have two customers that have 8,000 users connected to the solution. They are in the automotive industry. The users are a combination of sales people, service representatives and executives.  There is a tremendous ability for Docker to support a lot of users.

The customer service is good. 

The setup was very easy, but if you get into something with the backup agent or the API, that is when you may begin to stumble. Sometimes this causes a slower time for implementation and ultimate deployment. 

Our standard procedure is to look at the requirements, set of a pilot, do some testing, and then release the solution. It can take several weeks, and it depends on understanding our customers' needs. We have our own staff who complete the process.

At times, my customers are upset with the cost of the product. Other solutions seems inexpensive, in comparison. But, I tell my customers that once you start putting the solution together, will you realize that it will cost more than Rackspace Docker. 

We looked at VMware and Hyper-V, as well as Amazon. But, we stayed with Rackspace Docker becuas ewe already know that this is doing the best in terms of what it is offering.

My advice is in regards to the security. Many of my customers do not care enough about security, they have a disbelief that once you are in a cloud, you are automatically secure. This sis not the case at all. You need to understand that nothing is guaranteed if you do not follow the right rules. You need proper monitoring tools to keep the work-site safe and secure. It may cost the customer more, but it is worth every penny.

What I like most about Docker is that it is straightforward and easy to use, yet powerful. The graphical interface is very user-friendly and reporting is fast and effective.

Sometimes it is difficult to access the quality of information on Docker. I also feel that it is not a 100% secure product and I'd say there is room for improvement in the security area and functionality. I would also like to see more features inside Docker as well as more integration with different solutions.

The solution isn't always that stable.

I believe Docker is scalable.

I like their technical support but I mostly use their external documentation.

The initial setup was really easy and the deployment was fast and straightforward. I did everything myself.

We use the free version of Docker.

I don't use any other software, given that Docker is our solution.

My advice to others is to just do it. It is a no-brainer. I really recommend this solution and on a scale from one to ten, my rating is a nine.

We use this solution for the virtualization of monolithic apps, providing a better scalable and agile solution.

This solution has improved our organization with the agility, microservices approach, and scalable solutions for distributed systems.

The most valuable features of this solution are scalability and agility. It is easy to manage and deploy.

The orchestration and tracing should be improved.
