| Containers are chroot with a Marketing Budget |
| |
| |
There are many ways to understand how containers work, but most useful explanations are actually simplifications.
Many people have settled on explaining containers by calling them ‘light-weight VMs’ and they are light-weight because they ‘share the kernel with the host’. This is useful, but it simplifies a lot away. What is a ‘light-weight VM’? What does sharing the kernel mean?
Others will tell you containers are about namespaces and specific kernel visibility tweaks. This is also a helpful explanation because namespaces partition visibility, so that running containers can’t see other things on the same machine.
But for the author of this post, containers are just chrooted processes. |

| Enable Prometheus to Scrape Anything from Anywhere |
| |
| |
Prometheus is a server which wants to reach out and pull data from "scrape targets". It will generally do this using http requests. One problem with this design is that these targets are often inaccessible, hidden from Prometheus behind a firewall.
If not hidden, it means some port was exposed on some network, thereby giving Prometheus the ability to pull the data it needs.
OpenZiti solves this problem. |
