Environments are logical groupings of containers. All containers deployed inside an environment automatically have a private network built between them, enabling seamless communication.
One of the most difficult aspects of using containers is networking them together. Though this has gotten a bit easier over the years, nothing comes close to the simple, yet powerful approach of Cycle environments.
Every container deployed into the same environment has a private, encrypted network built between them, regardless of their geographic location. Instances in Tokyo can communicate with your database in California, using nothing other than the hostname. Containers obtain both a private IPv4 and IPv6 address, where the format is:
- IPv4 -
- IPv6 -
An environment service is a container Cycle starts within the environment to provide extra functionality. These services are created and managed automatically, but may have some configuration options available. At this time, two services are started in each environment:
All environments will have the choice of setting services to high availability or
HA. Marking a service as being
HA will be done through a checkbox on the environment dashboard under Environment Summary.
When you mark a service
HA Cycle will take steps to make sure that the service is deployed in a way that has a high failure tolerance. The service will spawn two - three more instances. If an instance fails, the platform will takes steps to bring that instance back online.
Swapping out of
HA mode will scale your instances back down to a single instance. Cycle follows FILO and will eliminate the instances, starting with the last instance created and moving toward the original instance.
From the environment dashboard, you are able to get a bird's eye view of all the containers running within. See where instances are deployed to, the number of containers/instances online, active services and their IPs, and a log of all activity within the environment. To get to the container dashboard:
- Select the Environments tab on the left in the navigation menu.
- Click the name of environment you wish to see from the list.
- Alternatively, from within an environment, click the "Dashboard" tab at any time.
While containers can be managed individually, you may wish to start or stop all containers within an environment simultaneously.
Navigate to an environment dashboard, and in the top right corner you will see three buttons:
- - Start All Containers.
- - Stop All Containers.
- Deploy Containers.
