"Container Orchestration Without the Headache"

What do you like best?

Hard to pick one thing I like best because the beauty of Rancher lies in how well it ties together many different features to make up one of the most complete, usable container orchestration platforms available. In particular, the API is very intuitive for building custom tooling against, and the UI gives me a complete view of my infrastructure from the container level down to the hardware itself.

What do you dislike?

After continued use, the web UI can become extremely slow to the point that I have to close my browser and re-open it in order to perform basic administration tasks. This has been a source of frustration, but my understanding is that newer versions of Rancher have addressed this (we currently run v1.2).

Recommendations to others considering the product

The current major release of Rancher (2.0 at this time) is built exclusively on top of Kubernetes. If you are considering Rancher, I would recommend becoming familiar with Kubernetes administration as well.

What business problems are you solving with the product? What benefits have you realized?

Rancher is our go-to control panel for simple, failsafe container deployments. We initially chose Rancher because it allowed us the flexibility to switch between many different container scheduling platforms (Mesos, Swarm, Kubernetes, and Cattle). As all of these solutions were very new, this flexibility gave us the confidence to move to a container-based infrastructure without the fear that we were investing in a container scheduling platform that might soon become obsolete. I do believe that v2+ of Rancher only integrates with Kubernetes, however I don't see this as a loss of flexibility as much as an indication that it has become a clear winner among the previously supported platforms. Since adopting Rancher, we've seen a significant reduction in downtime, since healthchecks and automatic rescheduling keep our systems healthy with very little manual intervention.

"Best containerization software around"

What do you like best?

Rancher supports a number of systems that other containerization software does not.

Nodes are set out in an easy to read way, and the other views provide a lot of information.

Creating containers was much simpler than the other software products I've used, with plenty of useful features, like 'Health check'.

Rancher is open source, so does not cost anything

What do you dislike?

Installation and set-up was time and people consuming.

The sheer amount of features on offer may be off putting to new users.

More network information would have been good, such as CPU and RAM specs.

Recommendations to others considering the product

Very feature rich, so set some time out to train users on how to use the system correctly. It's also time consuming to instal / set up for the first time. Other than that Rancher will do everything you need it to!

What business problems are you solving with the product? What benefits have you realized?

We use Rancher for our main containers and clusters, as it provides much more functionality in comparison with the other products available.

Since Rancher is open source, the product is totally free, saving the University money!

What Load Balancing solution do you use?

Thanks for letting us know!

"Rancher brings all your docker containers and hosts into one manageable place!"

What do you like best?

Rancher seems to be one of many few products which can bring docker hosts into one manageable interface and provides the ability to deploy stack's as opposed to just individual containers.

You can provide dockers at service level and not worry so much about the infrastructure behind them and is more of a service offering.

Its very easy to setup. The best bit I love is all you need to do is execute one command on any hosts you want to bring into rancher and docker automatically downloads and runs an 'Agent' image and automatically connects to your rancher host. From here you can even go out through firewalls as its client to server connection. A brilliant way of implementing such tool!

What do you dislike?

There isn't a great deal to dislike but over anything it would be that i've not found a way to move a container from one host to another - now that would be cool! Even better if it were drag and drop :) but otherwise its brilliant.

What business problems are you solving with the product? What benefits have you realized?

Rancher has provided a brilliant ability to implement multiple hosts and manage them all within one infrastructure. Even Rancher can run inside one of the hosts its managing! In my opinion this has to be the leading tool for docker users.

"A great tool for getting into docker orchestration"

What do you like best?

How easy Rancher was to get up and running. At the time we started using Rancher it had just reached 1.0 GA, and comparatively all of the other tools available like Docker Swarm seemed unnecessarily complex and more trouble than they were worth to use.

Rancher was easy to get setup, reliable, and made container orchestration a breeze.

What do you dislike?

There isn't much to dislike about Rancher. The high-availability feature could use some work. According tot the official docs as of version 1.5.x, there is still the following caveat when upgrading an HA Rancher server: "NOTE: When upgrading an HA setup, the Rancher server setup will be down during the upgrade." It seems like some work could be done to make the HA environment truly HA during the upgrade process.

Compared to other orchestration tools like, Kubernetes, it lacks some of the auto-scaling capabilities.

What business problems are you solving with the product? What benefits have you realized?

Rancher helped us increase our deployment time for new application versions. This has helped us innovate faster and deliver new features and/or bug fixes at a much quicker rate while utilizing the benefits on containers.

"Rancher is almost there"

What do you like best?

The Rancher interface is what sets it apart. Managing hosts, containers, and services is fairly intuitive.

What do you dislike?

There are still a few bugs here and there. Networking between the Rancher master and hosts sometimes becomes disconnected for no explicable reason. Re-registering the host is usually required. Rancher could also be a little more smart about balancing containers.

Recommendations to others considering the product

You may want to wait until Rancher 2.0 when first class support for Kubernetes is added.

What business problems are you solving with the product? What benefits have you realized?

Rancher allows us to deploy and manage our applications in docker containers.
