- Runs podman not docker
OCI compliant - cross platform compliant containers
SSH into containers
- You can
- Not by default
- You really shouldn't
Exec into a container is similar to SSH
Containers are supposed to be disposable
Container Management
- Kubernetes
- OpenShift/OKD
- Many others
To install you need to know
- SSH
- Basic Networking

Container Management gets you
- Load Balancing
- High Availability
- Monitoring
- etc
Containers are ephemeral by default
Containers typically have a shared storage backend
OpenShift/OKD Takes care of a lot of networking for you
There are two networks involved
- Communication - Container to Container
- LAN - Traditional Network
