Rotating out nodes during an upgrade is slow and potentially disruptive, however your systems should be built to handle this, and this is a good way of forcing it.
Deploy both and see which patterns you prefer, and what fits into your organisation better.
I have used both, but find Argo can be unnecessarily complex, and focuses solely as git as a source of truth for your k8s resources. The image updater can even write back to git to reflect version numbers etc, which is arguably an anti-pattern (git is not a database). However, the UI is excellent and is very powerful, and if your just getting started in the gitops space, its very intuitive.
I feel like the weaveworks team (who created flux) have encountered the problem of using git as a source of truth at scale. They let you specify other sources such as S3 and OCI containers, this gives you a lot more power to build custom, powerful workflows.
This means that you define your k8s resources (kustomizations definitions defining k8s resources, and flux resources) in git, but build, lint and test them in a CI/CD pipeline and publish them as a container. Then you can just tag that container with the cluster name or environment and treat your k8s resources like you would code. You can observe this with the flux ui too.
I think people get too hung up on the git part of gitops. All infrastructure should be defined in a version control system, and follow a sane CI process, but the way your cluster pulls that state to enforce it should be any source that is a reflection of that versioned code in SCM.
Absolutely, and argo really falls short when you have more complex patterns, like monorepos and promotion between different envs. Then you have to revert to argo events and workflows anyways and script your way through it.
It is mainly per host $15 or $23 PCM with the first 5-10 containers free then $0.002 per hour (~$1.5 PCM) per container. The insight and stats you get are quite granular and valuable however. For large scale deployments you can ignore certain containers etc.
Datadog is a pretty amazing product, and if you are careful and use it in the right way, it is very powerful, and cheaper than rolling your own LGTM Grafana stack (or similar). If you are not careful, or at a decent scale, you can easily spend obscene amounts of money. The metrics pricing is completely insane for example, and its easy for people to emit high cardinality metrics from apps and explode your bill. I think by this point you need to run an internal solution, and that is when it makes sense to double down on a combo of elastic, and grafanas stack for logging, tracing and metrics.
Based on my research the data available through the Linked API is very limited [1]. Basically `r_liteprofile` (name and photo), `r_emailaddress` (email) and `w_member_social` (post on a user's behalf). You can't get the users "vanity" url, profile information or posts. I'd love to be proven wrong though!
Expensify are doing this to a certain extent and have written about it before

There have been a lot discussions about this on HN over the years too.
There is a great story about an old man who lived in Hackney, East London who dug a series of tunnels under his house and surrounding houses. He was finally found out when other peoples houses started subsiding.
https://www.mylondon.news/news/nostalgia/mole-man-of-hackney...
When I was a kid I moved into my grandparents house and my uncle showed me a tunnel in his basement bedroom that he had started when he was a kid so he could sneak out. He turned 18 and moved out before he finished it, so it was my turn after that. By the time we moved out the tunnel was almost to the alley behind the house/backyard. Probably 60 to 70 feet long.
I always wondered what they thought when they tore the house down 15 years later.
I remember watching this video [1] about that same guy.
> "The Hackney Mole Man", In 2006, a network of tunnels were discovered beneath a house in Hackney, London. This discovery initiated a wave of public concern and media attention revolving around a lone figure, known locally as 'the Mole Man'.
Also, following an artist mentioned in the video, I tracked this page [2] and an interesting excerpt:
> Though flattered by my interest, the Mole Man proved to be extraordinarily difficult to work with. He was extremely racist, misogynistic and paranoid, and was only interested in talking about my sex life. His elusive, subterranean behavior – in many ways like that of an actual mole – and his obsession with tunnels was the ultimate Freudian manifestation. I soon realized, though, that the sexual overtones of our relationship threatened to over-take the project completely.

I wouldn't call that a "great" story since it was ultimately not just pointless but actively harmful to everyone.
Dashrath Manjhi's story is one I would qualify of "great", after his wife sadly died from what he perceived was a delay of care due to his village remoteness, he resolved to straight carve a roadway through the ridge abutting his village (over which the nearest town was located). Spent 20 years carving a 110m long and 9m wide road through the ridge, apparently with hammer and chisel.
Probably several chisels, and maybe even multiple hammers. I've done my share of chiseling and I've never worn one out yet but I'm not in the habit to going through 100+ meters of rock, even so my cold chisel is probably only about 80% the size that it was when I first bought it.
Oh yes absolutely, he explained that initially the other villagers had thought him crazy, then after a few years and visible progress some started giving him food or chipping in for tools replacement.
The sheer perseverance is humbling. I have a hard time staying focused on anything for much longer than week, and those tend to be interesting and intellectually rewarding, to be focused on transforming rock to rubble and removing it for decades is somewhere just below 'god mode'.
In the 90s I knew a guy on suburban Long Island who had started tunneling out of his basement. Last I heard he had gotten a couple of hundred feet under some neighbor's properties. Lost touch with him long ago and never found out how it turned out, but there were no reports in the local papers, so I can only assume he is still down there somewhere.
