knowledge dump on container runtimes | |
KataContainers | |
- image coupled with kernel | |
- light vm layer | |
- can run in nested virturalization environments if hardware supports and you can enable it in bios (ex. only bare metal EC2 instances, limits many cloud providers) | |
- slower startup time | |
- OCI compliant | |
- previously known as ClearContainers by Intel |
Nodes are not assigned public IP. If you have accessible VM in the same VNET as worker nodes, then you can use that VM as jump host and connect the worker via private IP.
Alternatively public IP can be assigned to a worker node. This readme shows how to do that.
