There is also Bottlerocket, an open source Linux distribution built to run containers:
Bottlerocket is optimized for running containers with high security isolation. The host OS is extremely minimal, it does not come with bash, an interpreter, ssh, or anything beyond the system basics needed to run containers. In fact it uses an immutable root filesystem. You aren’t intended to run or install things directly on the host at all.Bottlerocket is optimized for running containers with high security isolation.
