At Hyper_, our mission has always been Make running containers in production effortless. In the past few weeks, we keep collecting feature requests from our community to prioritize our roadmap. Today, we have some really exciting news for you.
Please install the new CLI.
Since our GA, one of the top feature requests is Security Group. By controlling the traffic for containers, it provides developers greater security and manageability:
hyper sg create web-sg -f web_sg.yaml: create a security group by adding rules that allow traffic to or from its associated containers
hyper run -d --sg=web-sg --name web nginx: specify one or more security groups with the container; when we decide whether to allow traffic to reach a container, we evaluate all the rules from all the security groups that are associated with the container
hyper update nginx --sg_add=new-sg: add/remove the security groups associated with containers
hyper sg update web-sg -f web_sg2.yaml: modify the rules for a security group on the fly; the new rules are automatically applied to all containers that are associated with the security group
More details can be found at Roadmap, Documentation.
CLI Auto Upgrade
Everyone loves command line tools! It is the enormously powerful to be able to control everything at fingertips. However, the trade-off is manual update. With this release, the built-in functionality will upgrade
hyper CLI whenever there is a newer version. It helps you to automatically keep your local utility up to date.
Faster Container Deployment
If a Docker image is built with the
VOLUME instruction, it creates a mount point with the specified name and marks it as holding externally mounted volumes, which will be initialized upon
create commands. The initialization process could take tens of seconds or even minutes to complete, depending on the data size.
--noauto-volume option allows faster container deployment, by skipping
VOLUME flag in the Docker image.
$ hyper run --noauto-volume`.
### Multiple Mountpoints
You can mount a volume at multiple different paths of a container.
$ hyper run -v vol1:/opt/data -v vol1:/opt/log --name=mycontainer ubuntu
Large Local Data Support
hyper run -v /local:/container allows you to load local data to remote containers upon launching. Previously the data size limit is a few hundreds MBs. The new release supports up to 10GB!
Enhanced Container Resource Limits
The new performance patch improves the container resource limits:
- Max open files: 1000000
- Max processes: 30604
- Max pending signals: 30604:30604
We hope that you will enjoy these new features in the new Hyper_. Please stay tuned on our roadmap as we continue to add more exciting features and if you have any questions you can always contact us through the Hyper_ console, Hyper_ forum, or on email@example.com.
