libpcap VS conduit

As long as your custom service used the rpcap protocol I'd expect it to be possible. You may find this GitHub page informative, since it includes some rpcap source code and one of the main Wireshark developers appears to be a contributor there.

mitmproxy can be used to find the HTTP request with the needed data in addition browser dev tools. At some point, I'll explore tcpdump and wireshark to reverse engineer websites for web scraping and share the learnings with you.

(Of course, this consideration should be appropriately downweighted by YAGNI, as threading memory management through prototype or internal utility code can by itself easily force it into very non-prototype amounts of effort.)

I am working with libpcap, a library that parses packets captured from tcpdump, which I have cIncluded from Zig.

Nmap and Wireshark, tcpdump tools can be used to scan networks and packets.

Also definitely start looking at tcpdump and wireshark. These are invaluable tools for the non-network engineer that is perhaps a sysadmin or analyst to use for network troubleshooting.

For future reference, libpcap is a library that Wireshark and many other network analysis tools use to record network traffic. It has its own file format that it can use to save the recorded network traffic to disk.

A lot is covered here and here, sar might be useful, getfacl and tcpdump and probably hundred more tools I am not even aware of. The easiest to learn those is to have a problem and identify and solve it with those tools, but to do that you need to know roughly what those tools can do.

For example, gopacket uses libpcap by default for capturing the traffic. Libpcap doesn't support network namespaces and we can't ask it to listen to traffic on a different namespace. However, we can change the network namespace of the calling thread and then start libpcap to see the traffic on a different namespace.

Leverage a service mesh like Istio or Linkerd to manage communication between microservices within the Kubernetes cluster. These service meshes can be configured to intercept JMX traffic and enforce access control policies. Benefits:

Looks like CNCF waved them through Graduation anyway, let's look at policies from July 28, 2021 when they were deemed "Graduated"

All maintainers of the LinkerD project had @boyant.io email addresses. [0] They do list 4 other members of a "Steering Committee", but LinkerD's GOVERNANCE.md gives all of the power to maintainers: [1]

> Ideally, all project decisions are resolved by maintainer consensus. If this is not possible, maintainers may call a vote. The voting process is a simple majority in which each maintainer receives one vote.

And CNCF Graduation policy says a project must "Have committers from at least two organizations" [2]. So it appears that the CNCF accepted the "Steering Committee" as an acceptable 2nd committer, even though the Governance policy still gave the maintainers all of the power.

I would like to know if the Steering Committee voted to remove stable releases from an un-biased position acting in the best interest of the project, or if they were simply ignored or not even advised on the decision.

I'm all for Boyant doing what they need to do to make money and survive as a Company. But at that point my opinion is that they should withdraw the project from the CNCF and stop pretending like the foundation has any influence on the project's governance.

From here, we can explore other developments and tutorials on Kubernetes, such as o11y or observability (PLG, ELK, ELF, TICK, Jaeger, Pyroscope), service mesh (Linkerd, Istio, NSM, Consul Connect, Cillium), and progressive delivery (ArgoCD, FluxCD, Spinnaker).

https://linkerd.io/ is a much lighter-weight alternative but you do still get some of the fancy things like mtls without needing any manual configuration. Install it, label your namespaces, and let it do it's thing!

Would it be possible to create a custom extension with the code that authorize traffic based on my custom access token?

Open source API Gateway (Apache APISIX and Traefik), Service Mesh (Istio and Linkerd) solutions are capable of doing traffic splitting and implementing functionalities like Canary Release and Blue-Green deployment. With canary testing, you can make a critical examination of a new release of an API by selecting only a small portion of your user base. We will cover the canary release next section.

I have experimented with other service meshes and I was able to get up to speed quickly: Linkerd = 1 day, Istio = 3 days, NGINX Service Mesh = 5 days, but Consul Connect service mesh took at least 11 days to get off the ground. This is by far the most complex solution available.

Out of the number of service mesh solutions that exist, the most popular open source ones are: Linkerd, Istio, and Consul. Here at Koyeb, we are using Kuma.
